Haas VF: Super Speed Halves the Table Load Nobody Reads

Haas publishes the table load rating for every VF it makes, and it publishes a different one for the Super Speed version of the same machine. A VF-2 is rated 3,000 lb. A VF-2SS is rated 1,500. On the VF-5 it goes 4,000 down to 1,750, a 56 percent cut, and the SS publishes the same 30 hp and the same 90 ft-lb of torque as the machine it is faster than.

So the Super Speed package buys you rpm and rapids, costs you half your fixture weight, and adds no cutting power at all. It is in Haas's own spec tables and we have not seen a used listing mention it.

This breakdown covers the whole roster and why a higher number is not a bigger machine, the suffix system, the specs that go backwards as you add capability, the two generation boundaries that decide what an old VF is worth, the red grease era and how to inspect for it, and what the used market actually pays as opposed to what it asks.

The roster, and the two numbers that are not machines

Haas currently lists VF-1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 and 14, in a long list of variants across 40 and 50 taper. The historical line adds the VF-0, VF-0E and VF-0E/EXT, and a VF-1YT that appears in Haas's 2014 shipping document and is gone from the catalogue today.

There is no VF-13. Not in the current catalogue, not in the 2014 weight document, not in the model list of the early-2000s operator's manual. Haas has never published a reason. One thing that will confuse you if you go looking: Haas service procedures list model coverage as VF-10/11/12/13/14, so the string does appear in Haas print. It is a range shorthand in a document that covers many families, not a machine. The superstition explanation is universal in the trade and we are treating it as inference rather than fact, because Haas has not said it.

And the VF-16 through VF-26 are racing cars. Haas F1 was founded in 2014 and first raced in 2016, and it names its chassis on the same Very First convention, so a search for a large VF number returns Formula One results. At least one dealer guide lists the cars in the same article as the mills. If a listing offers you a VF-17, it is not a machine tool.

One naming note Haas does publish: the V is vertical, and Gene Haas added F1 to mark the company's Very First One. That is the only part of the name Haas explains anywhere.

A higher number is not a bigger machine

At the bottom of the range there appears to be a clean rule. X travel equals ten times the model number plus ten, in inches.

The VF-4 and the VF-5 have identical 50 inch X travel. What separates them is Y, 20 inches against 26. From the VF-5 upward the number stops being a travel figure and becomes an ordinal size index.

Above that, the numbers run in pairs that share an X travel and step the Y.

The mistake this causes

A VF-7 has 84 inches of X. A VF-8 has 64. The higher number is the wider machine, not the longer one. A shop that needs length, sees a VF-8 listed above a VF-7, and buys the bigger number ends up with twenty inches less of exactly the thing it was buying. Haas publishes no explanation of the numeric ladder anywhere, so nothing on the machine or in the catalogue warns you.

The number does not track weight either. A VF-7/40 weighs 26,000 lb and a VF-8/40 weighs 24,800, per Haas document ES0428 Rev CA of September 2014. Treat those as period figures: that document stops at the VF-12 and does not contain a VF-14 at all.

The suffix system, and what Haas actually defines

The order is not consistent, and that is worth knowing before you try to parse a listing. A VF-5/40XT puts the taper before the travel suffix. A VF-3YT/50 puts it after. And an SS machine drops the taper token altogether: there is no VF-5/40SS, only a VF-5SS. Haas is not applying a grammar here, it is naming machines one at a time.

SS and YT are orthogonal and they compose. A VF-2SS is a standard 16 inch Y with the speed package. A VF-2YT is a standard spindle with Y raised to 20 inches and the table widened from 14 to 18. A VF-2SSYT is both. They are not a ladder, they are two independent choices, and that is why the names get long.

One dealer definition to ignore. A published dealer guide defines TR as High Torque. Haas's own VF-2TR, VF-5/50TR and VF-6/40TR pages define TR as a two-axis trunnion rotary table for 5-axis work. The manufacturer settles it.

The spec ladder, 40 taper

Current-generation figures from Haas Automation UK product pages, retrieved September 2026.

Every 40-taper VF spindle is 30 hp with 90 ft-lb at 2,000 rpm as standard, Super Speed included. Haas also publishes an optional 40-taper two-speed gearbox at 250 ft-lb at 450 rpm, which is a genuine upgrade and should not be confused with the 250 ft-lb figure in the next section, where the same number is a 50-taper downgrade. The 50-taper machines are a different animal: 7,500 rpm, 340 ft-lb at 700 rpm, and a two-speed geared head rather than an inline direct drive.

One figure we are flagging rather than asserting. Haas's VF-11 and VF-14 pages both print a 28 inch table width alongside 40 inches of Y travel, the same width as the 32 inch Y machines they sit beside. Two differently framed reads returned the same thing. If that is right it means the extra Y carries the spindle past the table edge rather than over more table. Confirm it against a machine-specific quote before you plan a fixture around it.

Seven specs that go the wrong way

1. Super Speed halves your table load. VF-2, 3,000 lb. VF-2SS, 1,500. VF-3YT 3,500 to VF-3SSYT 1,750. VF-4 3,500 to VF-4SS 1,750. VF-5/40 4,000 to 1,750, a 56 percent cut. VF-6/40 4,000 to 2,000. A shop that buys a VF-5SS for cycle time and then loads a tombstone is more than 2x outside Haas's published rating.

2. Super Speed adds no torque at all. Every 40-taper SS model publishes the same 30 hp and the same 90 ft-lb at 2,000 rpm as the standard machine. You are buying spindle speed, rapids and a bigger tool changer. For heavy roughing in steel the SS gives you nothing the base machine does not have, while costing you half the table rating.

3. The high-speed 50-taper option removes a quarter of your torque. On a VF-6/50 the standard spindle is 7,500 rpm and 340 ft-lb. The optional 10,000 rpm spindle is 250 ft-lb at 700 rpm. That is 90 ft-lb gone, 26 percent, on a machine bought specifically for torque. A used VF-6/50 advertising 10,000 rpm as an upgrade is advertising a downgrade for most 50-taper work.

4. Choosing 50 taper costs you rpm, and rules out Super Speed entirely. VF-5/40 runs 8,100 rpm. VF-5/50 runs 7,500. You gain 340 ft-lb against 90, which is an enormous win for heavy cuts, but there is no 50-taper Super Speed VF anywhere in the catalogue. SS is a 40-taper-only package.

5. Bigger machines are dramatically slower, on the axis that grew. VF-1 through VF-4 rapid at 1,000 ipm. The VF-5 and VF-3YT drop to 710. The VF-6/40 through VF-9/40 run 600, though the VF-7SS and VF-8SS get 1,200. And the VF-10 through VF-14 traverse X at 360 ipm, 36 percent of a VF-2, on a machine with four times the travel. Air-cutting time on a long-bed VF is brutal, and it is worse inside Super Speed too: the VF-2SS gets 1,400 ipm while the VF-5SS and VF-6SS get 1,200.

6. YT costs the VF-3 nearly a third of its rapids, and costs the VF-2 nothing. A VF-3 rapids at 1,000 ipm. A VF-3YT rapids at 710, for six inches of Y, with the spindle, the table load and the tool capacity unchanged. The VF-2 and VF-2YT are both 1,000 ipm, so this is a VF-3-specific trap rather than a rule about YT.

7. Bigger machines hold fewer tools. VF-6/40 and VF-8/40 carry 30+1. The VF-7/40, VF-9/40, VF-10/40, VF-11/40, VF-12/40 and VF-14/40 all carry 24+1. The Super Speed versions of those frames go back up to 30+1, so this is a configuration fact rather than a size rule. The VF-7/40 has fewer pockets than the smaller VF-6/40, and a VF-11 with 120 inches of X holds fewer tools than a VF-2SS with 30. Tool capacity is not monotonic with size anywhere in this family.

And the trunnion is in a category of its own. A VF-2 table is rated 3,000 lb. The VF-2TR trunnion platter is rated 80 lb, with a 17.5 inch maximum swing. Bolting it on removes 97 percent of your usable part weight. It also eats Z clearance by sitting on top of the table, and Haas does not publish the resulting Z figure on any TR page, which is worth knowing before you plan a job around one. For scale, a UMC-750 platter takes 660 lb.

Thirty years of one model name

The VF-1 launched at IMTS in 1988 at 49,900 dollars, the first American-built VMC under fifty thousand. It is still in the catalogue. That means "Haas VF-1" in a listing spans nearly four decades of machine.

Identical work envelope, 50 percent more spindle power, one model name. The same 20 to 30 hp story runs across the 40-taper line. A listing that says only Haas VF-1, or only Haas VF-2, has told you the travels and almost nothing else. The year matters more than the model number on this family, which is the opposite of how most listings are written.

Two generation boundaries, and only one is the one people talk about

The Next Generation Control arrived in 2016. The figures that follow come from dealer and monitoring-vendor documentation rather than from Haas, whose own control pages we could not reach. A Classic control is commonly cited at 1 to 16 MB of program memory and moves data over RS-232. NGC starts at 1 GB, goes to 8, runs a 15.6 inch touchscreen and has Ethernet with remote monitoring. On a modern 3D toolpath that difference decides whether the program fits in the machine at all.

You can tell them apart in thirty seconds. NGC has a wired network page under Settings and shows Setting 143 as a number. Classic shows RS-232 settings on the I/O page and Setting 143 as on or off. Machines older than either show neither.

But 2016 is not the obsolescence line, and this is the part that costs money. The boundary that matters is older and it is about the processor, not the screen. Owners reported from October 2016 that Haas had declared CRT-era main boards unavailable, with replacement quoted at 10,000 dollars. By July 2018 an owner account put the systematic electronics replacement at approaching 20,000 dollars, having been less than half that a year earlier.

Ask the right question

Not "is it Classic or Next Gen." Ask "is it CRT or LCD, and which processor generation." A late Classic machine from roughly 2005 to 2015 is not in the obsolete-board group and has a healthy parts aftermarket behind it. A CRT machine is the one carrying a five-figure repair that exceeds what the machine is worth.

The red grease era, and how to inspect for it in five minutes

This is the best-documented defect story in the family, and Haas dates it themselves. Their service alert of 7 November 2022 states that machines built from April 2014 to August 2022 used Haas Liquid Grease, that machines after August 2022 use Haas Axis Lubrication Oil, and that Liquid Grease cartridges and refills are no longer available.

What owners in that window actually report. Lines plugging, and the signature symptom of grease following the path of least resistance: one axis flooded while another gets nothing. On a 2012 VF-2, a first-hand report describes one Y-axis rail pristine and the other showing rust and pitting. The forum thread carrying most of this ran in early 2016 and ended without resolution, so we are reporting it as owner experience rather than as an established failure rate.

The five-minute test, and it is the useful part. An owner running a 2014 VF-2SS on red grease alongside a 2016 machine on purple reported the 2014 showed no significant grease usage while the newer machine's canister was half gone at fewer hours. A grease reservoir that is not going down is not being economical. It is not delivering lubricant. Check the reservoir level against the machine's hours, then pull the Y-axis way covers and look at both rails directly.

What a documented conversion is worth. Haas publishes kit 93-2755A to convert red grease to oil and 93-2601B to replace the plastic reservoir with metal, along with procedure AD0659 for the red grease conversion and AD0629 for the Liquid Grease one, covering the VF line and much of the rest of the Haas catalogue. A machine with the conversion done and papered is genuinely worth more. Rail pitting is not economically repairable against the value of the machine, because it means rails and trucks on something worth 30,000 to 50,000 dollars.

One nuance on the dates. Haas's cutover is April 2014, but owner reports place red grease machines in the field on 2014 and even 2016-badged builds, including a 2016 VF-3 whose canister failed with no warning and no alarm. Treat model years 2010 through 2016 as the inspection window, with April 2014 as the point where the risk starts falling rather than ends.

The used market, and it is the deepest one there is

Everything we have written about thin families does not apply here. On one marketplace carrying 3,130 used vertical machining centers across all brands, surveyed in September 2026, 886 of them are Haas. That is 28 percent of the entire category, and 3.6 times the second brand on the same platform, which showed 246. For contrast the same platform listed 16 Chiron and four Yasda.

One finding cuts against expectation. By total listings, not by the priced sample in the table below, the single deepest model is not the plain VF-2. It is the VF-2SS, and across the VF-2, VF-3 and VF-4 the Super Speed variants outnumber their standard counterparts. The speed package was sold in enormous numbers and is now the volume used product.

Asking prices, and they are asks not sales

The VF-5 and large-frame bands rest on one or two machines and we are not going to dress them up as bands. Everything above excludes machines listed as call for price, which pulls both the newest and the most tired machines out of the sample.

What the market actually pays

This is the number nobody publishes, and getting it required going to the one venue that reports completed sales, because the machine tool auction industry systematically withholds hammer prices. We checked six major auction platforms. One closed VF-2D lot states it plainly: the auctioneer has chosen not to publish the price of this lot. Anyone quoting Haas VF auction results from those platforms without an account is quoting asks.

Median gap on an old machine is roughly 65 percent, across four comparisons. Read that carefully, because it is a channel gap and not purely a negotiation gap, and because four comparisons is a small sample to hang a rule on. It bundles together an as-is private sale against a dealer offering power-up and some recourse, the buyer carrying rigging and freight and risk, and real condition differences the listing never disclosed.

And it reverses at the good end. A well-specified VF-2D with a fourth axis and an advertised 30,000 rpm spindle, which is far above anything Haas publishes for a VF and so is either an aftermarket high-speed head or a listing error, cleared above the dealer ask for a plain contemporary VF-2. The honest summary: on a pre-2005 VF with no options and no service history, expect one-third to one-half of the ask. On a documented, well-optioned, low-hour machine the gap collapses to nearly nothing.

Where the curve flattens, and where it falls off

There is a genuine plateau at roughly 16 to 25 years, where a VF is priced on capability rather than age: the step down across that span is 21 percent against 38 percent in the bucket before it. Then there is a cliff past about 26 years, and the cliff is the control, not the iron. A 1999 VF-4 asking 15,500 and transacting at 6,900 cannot absorb a 20,000 dollar electronics replacement. That arithmetic is what sets the floor.

The oldest VFs still commanding real money are the big ones. A 1999 VF-5 asks 33,000 at 27 years old, against 9,500 to 20,000 for contemporary VF-2s and VF-3s. A 2003 VF-7B/40 cleared under 29,500. The mechanism is replacement cost and scarcity of envelope: a new VF-6 was listed at 179,500 and a new VF-8/40 at 229,750, both dealer figures, and the VF-6 one does not say which taper or variant it is, so a large frame at 33,000 is roughly 14 to 18 percent of new, and a worn big machine still does work no VF-2 can do at any condition. A thirty-year-old VF-2 competes against fifty other VF-2s. A twenty-seven-year-old VF-5 competes against almost nothing.

Hours on a Haas are weaker evidence than you think

Haas controls carry three visible timers under CURNT COMDS, page down: power on time, cycle start time and feed cutting time. All three can be zeroed by any operator with the origin key. Non-resettable totals exist behind a service entry sequence, but an owner report confirms that installing a new control software version resets those too, and over a twenty year life a software update is routine maintenance rather than tampering.

The habit that actually tells you something is the ratio. Compare power-on hours against feed-cutting hours. A machine with 40,000 power-on and 4,000 cutting has led a completely different life from one with 12,000 and 9,000.

And here is the market fact behind all of it. Across the 53 priced dealer listings we examined, which includes a few models too thin to break out in the table above, hours were stated in zero of them. In the completed sales, zero. On this market age is the priced variable and hours are not, because hours are neither disclosed nor trusted. Which means a seller with genuinely low and verifiable hours has a real arbitrage, and a buyer who checks both counters himself is holding information nobody else in the deal has.

What holds value, and the one option that does not

These are associations in asking data, not option price lists. The dominant confound is that well-optioned machines are also newer and better cared for. That is also why the Super Speed figure here, plus 36 percent, is so far below the raw gap in the asking table above, where the VF-2SS median sits at 59,750 against 26,500 for the plain VF-2. That raw 125 percent gap is mostly age, because the SS machines in the sample are much newer. The 36 percent is what is left once you compare machines from the same era, and it is the number to trust.

The fourth axis is the finding worth acting on. Dealer guidance calls it a high-value option and the listing data does not support that at all. The likely mechanism is that a rotary table is portable: it unbolts and sells separately, and the used parts market confirms it, with rotary controllers, driver boards and conversion boxes all trading briskly on their own. Price the machine and the rotary separately rather than paying a bundled premium. The sample is three machines, so treat it as directional, but the mechanism is sound and it is the opposite of the received wisdom.

VF against the rest of the Haas catalogue

The thing a VF cannot be optioned into. The VM table carries T-slots running in both X and Y, and Haas lists a multi-fixturing table among the VM's standard features. A VF table has slots in one direction only. There is no VF option that adds cross-slots, because it is a different casting. The VM also ships the 12,000 rpm inline spindle and the side-mount changer as standard where a VF-2 gets a 20-pocket carousel.

The trade runs both ways though. A VM-2 rapids at 710 ipm, slower than a plain VF-2 at 1,000 and far slower than a VF-2SSYT at 1,400, on identical travels. The VM is not simply a better VF, it is a different job.

And a TM is not a cheap VF. One tool, 200 ipm rapids, a 4,000 rpm 7.5 hp spindle. It is a CNC-controlled toolroom machine. Any listing pricing one against a VF is mispositioned.

Resell CNC Take

We see more used VFs than any other machine, and the pattern is consistent: buyers shop the model number and the year, and the money is in neither. It is in the control generation, the lubrication era and the option list.

If we walk a VF for a client, the first three things are the processor and screen generation, the grease reservoir level against the hour meters, and the Y-axis rails with the covers off. None of those three are in the advert, and all three move the number more than the difference between a VF-2 and a VF-3.

Advice that costs us the sale

If you are looking at a pre-2005 VF, assume the control is the whole risk. The iron on these machines outlasts the electronics comfortably. A CRT-era machine carrying a five figure board replacement is worth what a running machine is worth minus that number, and on most of them the arithmetic goes negative. Do not let a low price talk you past it.

If you want speed, buy the SS. If you want to cut, do not. Same power, same torque, half the table rating. A standard VF-4 with probing and a conveyor will out-earn a bare VF-4SS in most job shops, and it will cost less.

And if you are selling one, the margin is in the three things nobody supplies. Verified dual-counter hours, a ballbar report, and for a 2010 to 2016 machine, paperwork showing the lubrication conversion. The market cannot get those and prices as if nobody has them.

The good news, and it is real: this is the deepest used market in machine tools. Eight hundred and eighty-six machines on one platform means you can wait for the right one, walk away from a bad one, and check a price against fifty comparables. That is worth more than any single spec on this page.
