Tschudin Centerless Grinding Machines

Tschudin specializes almost exclusively in centerless cylindrical grinding, a discipline the company has refined for over a hundred years. The modern lineup is anchored by the Cube series, a compact, fully enclosed platform engineered for ultra-precision in-feed and through-feed grinding of small diameter parts. Tschudin's ecoLine and proLine machines extend the range with configurations optimized for medical, automotive, and high-volume production grinding. Legacy HTG, T25, and earlier Tschudin centerless models remain in demand on the used market thanks to their proven Swiss build quality and continued parts support.

Applications & Industries

Tschudin centerless grinders are the machines of choice for watch components, medical implants, surgical instruments, fuel injection parts, ball and roller bearings, hydraulic components, and precision shafts. Any application requiring tight roundness, consistent surface finish, and micron-level diameter control on cylindrical workpieces is a candidate for a Tschudin. Used Tschudin machines are particularly attractive to job shops and contract manufacturers looking to add Swiss-grade precision grinding capacity at a fraction of new-machine investment.

What to Look for When Buying a Used Tschudin

Tschudin centerless grinders are built to micron-level Swiss precision standards. A well-maintained Tschudin holds tight tolerances after decades of service; a neglected one shows wear that is expensive to correct. Focus evaluation on the spindles, slide and workrest interface, and the control.

Inspect the grinding wheel and regulating wheel spindles. These are the heart of the machine. Check spindle runout at both wheel mounts. Listen for bearing noise during no-load spin and after warm-up. Look for coolant ingress at the spindle housings — a sign of seal failure leading to bearing contamination. Refurbishment is specialized work, so evaluate carefully.

Check the slides, ways, and workrest blade. Examine the regulating wheel and grinding wheel slides for smooth travel without stick-slip or measurable backlash. Inspect way surfaces and wipers for scoring, corrosion, or coolant pitting. The workrest blade and mounting should be free of chatter marks; this interface controls part roundness directly. Blades replace inexpensively; a damaged mounting cannot.

Test the coolant, hydraulic, and dressing systems. Verify coolant flow, filtration, and pump health. On hydraulic-equipped models, check for leaks, pressure stability, and reservoir cleanliness. Cycle the wheel dressers and confirm slide accuracy — dresser wear translates directly into part geometry errors. Inspect auto-loading systems if equipped.

Identify the control platform and confirm operation. Tschudin centerless grinders ship with Fanuc or Siemens CNC controls; legacy units may carry earlier Tschudin-branded packages. Power up the control, check for alarms or battery-backed memory loss, and verify smooth axis motion under MDI. The control should match your shop's expertise.

Tschudin Centerless Grinder Models

Cube Series

The Cube 350 and Cube 400 are Tschudin's modern flagship centerless grinders: compact, fully enclosed for in-feed and through-feed grinding of small to medium diameter parts. Features include a vibration-damping mineral cast base, linear motor drives on later configurations, and quick-change tooling. Cube machines are common in medical, automotive precision, and high-end watch component production.

ecoLine 400

The ecoLine 400 is Tschudin's value CNC centerless grinder, built on the same precision fundamentals as the Cube and proLine but for shops needing Swiss accuracy without the full premium feature set. ecoLine machines are popular for general centerless work in automotive, hydraulics, and bearing component grinding.

proLine 400

The proLine 400 sits between the ecoLine and the flagship Cube, balancing precision, automation readiness, and serviceability. proLine machines are commonly equipped for combined in-feed and through-feed operation and remain a workhorse for medium to high-volume production.

Legacy HTG, T25 & Earlier Models

Tschudin's HTG 400 and T25 series, along with other legacy designations, circulate widely on the used market. These machines were built to the same Swiss standards as their successors and deliver excellent grinding accuracy when properly maintained. Parts and rebuild support is available, and many shops choose a refurbished legacy unit to add Swiss-grade capability at a sensible price.

How to Sell Your Used Tschudin

Tschudin centerless grinders hold strong resale value thanks to the brand's century-long reputation, limited production, and the specialized nature of centerless grinding. Cube, proLine, and ecoLine models see the strongest demand; legacy HTG units retain value in good mechanical condition.

Frequently Asked Questions About Used Tschudin Machines

Are used Tschudin centerless grinders reliable?

Yes. Tschudin has built centerless grinders in Switzerland since 1912, engineered for decades of precision service. Properly maintained used Tschudin grinders hold tight tolerances and deliver consistent surface finishes beyond their first owner's service life.

What CNC control does Tschudin use?

Current Tschudin centerless grinders are typically equipped with Fanuc or Siemens CNC controls, depending on model and specification. Legacy machines may carry earlier Tschudin-branded packages. Confirming the control matters for operator training, programming compatibility, and parts availability.

What should I inspect before buying a used Tschudin?

Focus on the grinding and regulating wheel spindles, slide and way condition, workrest blade interface, coolant and hydraulic systems, dressers, and the control. Spindle and slide wear are the most consequential and most expensive to address.

Which Tschudin models hold their value best?

The Cube 350, Cube 400, proLine 400, and ecoLine 400 hold the strongest resale values. Well-maintained legacy HTG and T25 machines also retain solid value, particularly where Swiss-grade capacity is needed but new-machine lead times are long. Call (844) 478-8181 for current guidance.

What industries use Tschudin centerless grinders?

Tschudin machines are used in watchmaking, medical (implants, surgical instruments, dental), automotive (fuel injection, valves, bearings), aerospace, hydraulics, precision shafts, and high-end tooling. Any application requiring tight roundness and consistent diameters on cylindrical parts is a candidate.

What is centerless grinding, and why is Tschudin known for it?

Centerless grinding holds the workpiece between a grinding wheel and a regulating wheel, supported by a workrest blade, without clamping in chucks or between centers. The result is exceptional roundness, fast cycle times, and ideal performance on small-diameter, high-volume parts. Tschudin has specialized in this discipline since 1912 and is widely considered one of the world's premier centerless grinder builders.
