What to Look for When Buying a Used Mikron
Mikron machines are built to Swiss precision standards, holding tolerances in tenths. High-speed spindles, linear drives, and thermally symmetrical structures are exceptional performers but demand careful inspection.
Inspect the high-speed spindle. Mikron HSM and MILL S machines run spindles from 20,000 up to 60,000 RPM with HSK-E32, HSK-E40, or HSK-E50 interfaces. Test runout cold and after full thermal warm-up, listen for bearing noise across the full RPM range, and verify rated speed without vibration. Spindles are the most valuable component and replacement is costly, so hours and history matter enormously.
Check linear motors and direct-drive axes. On HSM uLP (linear motor) models and MILL P/MILL S 5-axis machines, the rotary and tilting axes use water-cooled torque motors. Verify cooling function, check for leaks around the rotary table, and confirm the axes clamp for heavy roughing. Measure positioning accuracy in all five axes and verify 5-axis kinematic calibration.
Identify the control generation. Mikron uses Heidenhain iTNC 530 on older units, TNC 640 on mid-generation machines, and TNC 7 or Siemens Sinumerik ONE on current models. Newer MILL E and VCE machines may be configured with Fanuc. Check for Mikron Smart Machine modules (Intelligent Thermal Control, Intelligent Spindle Monitoring, Operator Support System), which add production value.
Verify automation. Many Mikron machines shipped with integrated pallet changers, robot loaders, or System 3R tooling. Confirm all components are present and functional. Missing pallets, fixtures, or robot cells substantially reduce resale value.
Mikron High-Speed Machining Centers (HSM Series)
HSM 400, 500, 600, 700, 800
The HSM series is Mikron's flagship high-speed line and the most commonly traded Mikron family on the used market. The HSM 400 and 500 are compact 3-axis mills ideal for electrode production, small molds, and precision components. The HSM 600 and 700 handle mid-size mold and die work. The HSM 800 takes workpieces up to 1,000 kg and was often configured with integrated pallet changers. Spindles range 20,000 to 42,000 RPM.
HSM 400U / 600U / 400uLP (MILL S Series)
U-suffix models are full 5-axis variants with integrated rotary/swiveling tables. The HSM 400uLP (now part of the MILL S series) uses linear motors instead of ballscrews for maximum dynamic performance, popular in graphite electrode work and micromachining.
Mikron High-Performance Machining Centers (HPM Series)
HPM 450U, 600U, 800U, 1150U, 1350U
The HPM series delivers higher torque and heavier chip loads than the HSM line, targeting production part-making rather than mold work. HPM-U models offer 5-axis capability with HSK-A63 spindles (12,000 to 20,000 RPM), trunnion tables, and large tool magazines. Common applications: aerospace structural components, medical implants, and automotive parts.
Mikron 5-Axis Universal Platforms
UCP Series (Legacy Universal)
The UCP series (UCP 600, 710, 800 Duro, 1000, 1150) was Mikron's original 5-axis universal milling platform. UCP 600 Vario adds extended rotary/tilting axis range. Most UCP machines run Heidenhain iTNC 530 with HSK-A63 spindles (12,000 to 20,000 RPM). Proven, serviceable machines with ongoing parts support.
MILL P U Series (Current 5-Axis)
The MILL P 500U and MILL P 800U are current-generation 5-axis machines in a gantry-type design with water-cooled direct drives, thermally symmetrical structures, and Machine & Spindle Protection (MSP). The MILL P 800U ST adds turning up to 800 RPM for mill-turn operations. Controls: Heidenhain TNC 640 or Siemens 840D sl.
Mikron 3-Axis Machining Centers
MILL E and VCE Pro Series
The MILL E series (MILL E 800, 1200) delivers 3-axis vertical machining at accessible investment levels, with 12,000, 16,000, or 20,000 RPM spindle options. The VCE Pro series (VCE 600, 800, 1000, 1200, 1400, 1600, 2000 Pro) handles workpieces up to 3 tons and 2 meters, popular for mold, die, and large-part work. Legacy VCP and VC models remain widely traded.
How to Sell Your Used Mikron
Mikron machines hold strong resale value thanks to Swiss build quality, ongoing parts support, and steady demand from mold, die, aerospace, and medical shops. HSM, MILL P, UCP, and VCE Pro machines with Heidenhain controls and documented service history command the highest offers.

Frequently Asked Questions About Used Mikron Machines
Are used Mikron machines reliable?
Yes. Mikron is Swiss-engineered to exceptionally tight tolerances, with thermally symmetrical structures and premium components. Under GF Machining Solutions, parts, service, and spindle rebuild support are available through a worldwide dealer network. Well-maintained Mikron machines routinely deliver 15 to 20 years of productive service.
What CNC control does Mikron use?
Most Mikron machines run Heidenhain controls: iTNC 530 on older units, TNC 640 on newer machines, and TNC 7 on current production. Siemens Sinumerik (840D sl and Sinumerik ONE) is an alternative on many models. Select MILL E and VCE Pro machines may be equipped with Fanuc.
What is the difference between Mikron HSM and HPM?
HSM (High-Speed Machining) centers run ultra-high-speed spindles (20,000 to 60,000 RPM) optimized for mold, die, electrode, and fine-finish work. HPM (High-Performance Machining) centers use heavier-torque spindles (12,000 to 20,000 RPM) built for production part-making with higher material removal rates.
What Mikron models hold their value best?
HSM 400/500/600, HPM 800U, UCP 600/710/1000, VCE 800/1000 Pro, and MILL P 500U/800U all maintain strong resale values. Machines with linear motors, integrated automation, or recent spindle rebuilds command premiums.
Are Mikron parts still available?
Yes. Mikron milling machines are supported by GF Machining Solutions, with production and service in Switzerland, the US, Sweden, and China, plus sales in over 50 countries. Spare parts, spindle rebuilds, and technical support remain available for most models in active use.
