Used Rollomatic Buying Guide: What to Inspect Before You Purchase
Rollomatic machines are built to ultra-precision tolerances, and a well-maintained example delivers decades of production output. Because these grinders rely on tightly integrated mechanical, hydraulic, and software systems, our buying team focuses on four critical areas.
Spindle Condition and Runout
The grinding and workholding spindles are the heart of any Rollomatic. Look for documented runout values (Rollomatic specifies under 0.002 mm concentricity on the patented shank guide and steady rest), bearing hour counts, and any history of crash damage. Listen for noise during a power-on test and verify smooth ramp-up to top RPM. On synchronous-spindle GrindSmart models, confirm the motor holds constant rotation under load.
Linear Motors, Hydrostatic Slides, and Way Systems
Most modern GrindSmart, ShapeSmart, and LaserSmart machines use linear and torque motors with oil-shared cooling and grinding coolant. Pull recent error and alarm logs to check for thermal events, encoder faults, or position errors. On hydrostatic-slide machines (GrindSmart Nano6 and 830XW), verify the oil supply, filter condition, and pressure stability. Older Strausak and pre-linear-motor models should be checked for backlash and lubrication history.
VirtualGrind Pro Software, Licenses, and Control Generation
Rollomatic’s proprietary VirtualGrind® Pro programming software (VGPro) is one of the most valuable assets bundled with the machine. Confirm the software version, that the license is transferable, and that the control hardware generation is still supported. Strausak machines using NumrotoPlus follow the same rule. We help buyers verify this with the OEM before purchase.
Automation, Wheel Changer, and Loader Condition
Rollomatic machines are often configured with high-speed pick-and-place loaders (capacities up to 1,360 tools), 6-position wheel and nozzle changers, and 6-axis Fanuc robot integrations on RW models. These options carry significant value. Inspect gripper wear, verify loader and changer cycles, and confirm in-process gauging probes are functional and calibrated.
Rollomatic Machine Series Overview
GrindSmart 5-Axis Tool Grinders (528XS, 530XW, 530XF, Nano5)
The 5-axis GrindSmart platform handles the bulk of round-tool production: endmills, drills, reamers, and burs from sub-millimeter to mid-range diameters. The Nano5 specializes in micro-tools and dental instruments. The 528XS, 530XW, and 530XF are widely deployed production grinders. Optional robotics and wheel changers are common.
GrindSmart 6-Axis Tool Grinders (628XW, 630XS, 630XW, 660XW, 830XW, Nano6)
The 6th axis allows the grinding wheel head to incline, improving accuracy on ballnose endmills and corner radii while shortening cycle times. The 630XW and 630XW3 are workhorses for tools 0.1 to 20 mm. The 660XW adds peel grinding capability. The 830XW pushes capacity to 32 mm diameter and 200 mm flute length. The Nano6 brings hydrostatic precision to micro-tools below 0.002 mm concentricity. The 630RW3 series adds a 6-axis Fanuc robot for medical long-drill production up to 500 mm.
ShapeSmart Cylindrical Pinch and Peel Grinders (NP30, NP3+, NP5, NP50, RPG II)
The patented pinch and peel process uses simultaneous roughing and finishing wheels to deliver finished blanks in a single pass. The NP30 covers 0.025 to 25 mm in 4 axes. The NP3+, NP5, and NP50 add a 5th axis for non-round shapes (flats, hexes, ellipses, cam profiles) used in punch and mold work. The RPG II is a hydraulic plunge grinder for high-volume infeed.
LaserSmart Laser Machining Centers (510, 510 femto, 810XL)
The LaserSmart line replaces conventional EDM and grinding for ultra-hard materials. The 510 handles PCD, CVD, and natural diamond tooling. The 510 femto, with a femtosecond laser source, achieves cutting edge radii under 1 µm. The 810XL handles tools up to 300 mm diameter, 350 mm length, and 15 kg, with a 30-part robot loader.
Strausak ONE Job-Shop Resharpening
The Strausak ONE linear is built for resharpening and high-mix, low-volume work. Compact footprint, short setup, and the NumrotoPlus control make it accessible to smaller shops.
Sell Your Rollomatic: Top Dollar, Fast Turnaround
Rollomatic equipment holds its value better than nearly any other CNC grinder on the used market. Swiss build quality, OEM parts support, and steady demand from cutting tool producers mean clean machines move quickly. Resell CNC pays competitive cash and closes on your timeline.

3. Accept and close. If you accept, we coordinate inspection, rigging, and payment so you can clear the floor on your schedule.
Frequently Asked Questions About Used Rollomatic Machines
Are used Rollomatic CNC machines reliable?
Yes. Rollomatic builds vertically in Switzerland with proprietary spindles, slides, and software, and well-maintained units routinely run production for 15 to 20 years or more. Strong OEM parts and service support out of Mundelein, Illinois protects long-term ownership.
What CNC controls do Rollomatic machines use?
GrindSmart, ShapeSmart, and LaserSmart machines run Rollomatic’s VirtualGrind® Pro software with NanoGrind machine control on Fanuc or Siemens base CNC platforms. Strausak machines use NumrotoPlus.
What should I inspect when buying a used Rollomatic?
Focus on four areas: spindle runout and bearing condition; linear motor and hydrostatic slide health; software version and license transferability; and automation including loaders, wheel changers, and probing systems.
What is the best-value used Rollomatic for a small tool shop?
The 5-axis GrindSmart 528XS and 530XW are popular entry points for endmill and drill grinding. For blank prep, the ShapeSmart NP30 is a strong value. For resharpening, the Strausak ONE offers fast setups and a smaller footprint. Call us for a recommendation.
What is the difference between 5-axis and 6-axis GrindSmart machines?
The 5-axis machines cover most round-tool grinding. The 6th axis on machines like the 630XW and 660XW lets the grinding wheel incline during cuts, improving geometry on ballnose endmills and corner radii and shortening cycle times by reducing empty moves.
Does Rollomatic still support older machines?
Rollomatic Inc. provides parts, field service, training, and applications support from its Mundelein, Illinois headquarters. Available support depends on model and control generation; verifying support is part of our pre-purchase inspection.
Can I finance a used Rollomatic through Resell CNC?
Yes. We work with multiple equipment finance partners offering competitive rates. Visit our financing page or call (844) 478-8181.
