CNC Specialist’s Guide: Selecting the Right Used, Surplus, Secondhand, Pre-Owned Hurco VMX42 CNC Vertical Machining Center made in Germany
Here’s a CNC Specialist’s Guide to selecting the right used, surplus, second-hand, or pre-owned CNC Vertical Machining Center Hurco VMX 42i or Hurco VMX 42 SRTi CNC Vertical Machining Center (commonly referred to as Hurco VMX42) — including key technical machine details, practical selection criteria, and what to check before you buy.
1. Machine Overview — Hurco VMX42 Series
The Hurco VMX42 family are 3-axis or advanced vertical machining centers designed for versatile milling, drilling, and tapping operations in low to medium-volume CNC production environments. They are widely used in mold & die shops, general fabrication, and job shops due to their ease of programming and robust build quality.
Common variants include:
- VMX42i – 3-axis standard machining center
- VMX42 SRTi – Swivel Head + Rotary Table (5-axis capable)
All VMX-42 machines share a compact footprint with large table capacity and robust structural rigidity for precise machining.
2. Core Technical Specifications (Typical)
Axis Travel & Table
Most used VMX42 machines offer:
- X-Axis Travel: ≈ 1,067 mm (42 in)
- Y-Axis Travel: ≈ 610 mm (24 in)
- Z-Axis Travel: ≈ 610 mm (24 in)
- Table Size: ~1,270 × 610 mm (50″ × 24″)
- Max Table Load: 1,360 kg – 1,750 kg range depending on variant.
Spindle & Tooling
- Spindle Taper: CAT 40 / SK 40 (BT 40 on some used units)
- Max Spindle Speed: ~10,000 – 12,000 rpm standard (some with higher speed options)
- Spindle Power: ~15 – 18 kW industry-typical
- Tool Changer: 24 – 40 pos. automatic tool changer
- Max Tool Diameter: ~80 mm
- Max Tool Length: ~250 – 300 mm
- Max Tool Weight: ~7 kg
- Rapid Traverse Rates: ~30 – 38 m/min on major axes.
Control Systems
Used units may be equipped with:
- WinMax CNC control — intuitive Hurco conversational + G-code interface
- Ultimax family of CNC controls (older style)
- Advanced software options (dxF import, rigid tapping, tool libraries).
3. Why Hurco VMX42 Is Popular in Used Markets
Versatility: Large table + generous travels make it suitable for a wide range of operations — from simple 3-axis milling to complex 5-axis when equipped with swivel heads or rotary tables.
Wide Support & Common Parts: Hurco machines are common worldwide; used parts and service manuals are often available for VMX42 models at competitive pricing.
Control Familiarity: WinMax and Ultimax controls are well known in job shops, easing operator adoption.
Modular Options on Used Units: Many machine sellers list optional pallet changers, tool probing, tool presetter interfaces, coolant systems and chip conveyors alongside base machine specs.
4. Practical Buying Considerations
a. Verify Machine Origin & Build Quality
- Confirm where the machine was originally manufactured or commissioned.
- Even though Hurco has global sales, the engineering and assembly of VMX42 machines trace back primarily to Hurco facilities in the USA — verify component provenance with documentation.
b. Inspect Critical Wear Areas
- Guideways: Check for wear on linear guides and ball screws; excessive backlash shows as chatter or chatter marks.
- Spindle Bearings: Noises or vibration at high speeds indicate bearing wear.
- Tool Changer Mechanism: Drum or arm ATCs are wear points; verify smooth operation without misfeeds.
c. Control & Software
- Check if the CNC control has been updated (WinMax latest builds preferred over older Ultimax on modern shops).
- Verify the program storage integrity and connectivity interfaces (USB / network).
d. Performance Test Cuts
- Always perform a test part cut on the actual material you will be machining. Check finish, dimensional accuracy, and tool life under load.
e. Parts & Service Availability
- Older VMX42 units sometimes have discontinued accessories or bespoke parts; ensure service availability of major components like spindle units and control cards.
5. Configuration Options to Review
When evaluating a used VMX42, confirm whether the machine includes:
- Coolant through spindle or high-pressure coolant system
- Chip conveyor and coolant tank upgrade
- Probing system (tool & part probe)
- Rigid tapping and high speed machining (HSM) software tools
- Rotary axis or swivel head attachments (for 5-axis capability)
- Tool presetter / networked tool data integration.

7. Final Tips for Used VMX42 Selection
- Documentation: Always request calibration certificates, maintenance logs, and control backups.
- Operator Interface: Units with WinMax CNC typically offer better usability and easier program transfer to modern CAM.
- Component Age: Consider spindle rebuild history and overall machine hours — high hours without rebuilds can be costly.
- Accessories: Machines sold with vises, fixtures, probes, and tool holders greatly reduce your setup costs.
- Machine Frame Condition: Check for table flatness and axis squareness — skewed axes often translate to out-of-tolerance output.
