EXPERT OM CEMTERLESS GRINDING
RELIABILITY THROUGH SIMPLICITY
Tschuding has been specializing in centerless grinding for more than 70 years with the development and manufacturing of centerless grinding machines for the production of high-precision mechanical components.Applications
TSCHUDIN’s centerless grinding machines are used in all industries where high accuracy mechanical components are required at low costs per piece.
A real all-rounder
The TSCHUDIN grinding machines handle a wide range of materials from steel and aluminium, glass, titanium, carbon, ceramic, germanium through to silicon and many more.- injection technology automotive
hydraulic systems - medical
- bearing
- aerospace
- power tools
- drive technology toolmaking
All advantages at a glance
Maximum reliability – what’s not there doesn’t go wrong- No hydraulics
- No ball screws
- No proximity switches
- No driving belts
- injection technology automotive
100% reliability - low thermal growth
- 100% Natural granite
High long-term stability, high temperature stability, outstanding attenuation properties and reliable grinding processes – all these characteristic features speak for the use of natural granite for all components that require high accuracy.
With TSCHUDIN machines, the machine bed and slide are made of 100% natural granite.
ecoLine & proLine
- The unique TSCHUDIN centerless grinding machine concept with digitalised configuration and grinding processes is designed for the highest possible process stability and machine availability. Linear drives on the X-, U- and W-axis ensure flexibility and productivity. The TSCHUDIN proLine also has a patented fourth CNC-axis (Y-axis, Patent US 9.085.059) for vertical movement of the regulation wheel. The work rest and dressing tool of the regulation wheel are fixed in position at the height of the grinding wheel.

TSCHUDIN ecoLine
- 3 axes
Manual settings- U grinding wheel axis
- W workpiece / dressing axis
- X regulation wheel axis
Manual settings- 1 – Configuring the workpiece superelevation
- 2 – Setting the height of the dressing tool
TSCHUDIN proLine
- 4 axes
Full automation- U grinding wheel axis
- W workpiece / dressing axis
- X regulation wheel axis
- Y height adjustable regulation wheel
CNC controlled setting of the regulation wheel height
The workrest and dressing tool of the regulation wheel are fixed in position at the height of the grinding wheel. This means the height of the workrest no longer needs to be adjusted.
Tschudin Series
CUBE 350
- The Cube 350 offers the best possible efficiency in a minimal space. With impressive set-up times, the compact centerless grinding has been developed specially for machining small components and small batch sizes.
New compact centerless grinding machine
- Almost as fast the changing tyres in Formula 1!
The changeover of the Cube 350 is reminiscent of a pit stop in Formula 1: We changed the grinding and regulating wheel in just six minutes - the next series can now be produced.
Minimal installation area, maximum efficiency
- The cube 350 is high-precision, three-axis centerless grinding machine with an extremely small setup area (2558 x 1735 x 1320 mm). The machine only needs to be accessible from the rear for maintenance. This allows multiple machines to be positioned closely in confined spaces.
Replacement parts reduced to a minimum & short set-up times
- The machine setup of the Cube 350 is simple and low-maintenance, thereby reducing operating costs over the long term.
The machine bed and carriage made from natural granite guarantee thermostable, highly precise and reliable grinding processes.
A big plus are the short set-up times and the simple and CE-compliant loading and unloading outside the grinding zone. The in-house software TSCHUDIN “easy” makes operation and automation easy and convenient.
Specially for machining small components
- The new compact centerless grinding machine was specially developed for machining small components with part diameters of less than 0.1 to 20 mm and small batch sizes.
Putting people at the heart of things
- The design should not only combine elegance and functionality. Our goal was to put the operator in the centre and make to convey fun and enjoyment at work.
The Cube 350 can be loaded safely and ergonomically by right-handers as well as left-handers. (Pat. CN111958342A; EP3741508A1; JP2020189399A; KR20200134167A; US2020368872A1)
Patented workpiece support
- The patented, movable workpiece support makes the Cube 350 a true all-rounder and extends the process options: roughing and finishing in a double cycle, grinding sharp edges, targeted approach to cones / chamfers and radii – the Cube 350 can be used in many ways.

400 ecoLine/proLine
A fine serie
"The investment in a Tschudin ecoLine 400 centerless grinding machine enables superfinishing of various precision parts in series production.” Pascal Schiefer, Leibold Group
Dressing from the front
- The CNC-controlled dressing from the front increases the precision and flexibility through interpolation of the axes (grinding wheel U / W, control wheel X / W). Any profiles can be created
100% natural granite
- The solid block construction of the grinding and regulation spindle slide made of 100% natural granite guarantees a constant cylinder shape and optimized surfaces.
Replacement parts reduced to a minimum & short set-up times
- Changing and adjusting the height of the support and setting up the dressing tools take place outside the grinding area, both manually and automatically. This makes it possible to load several workpieces one after the other onto the support and to process them in one cycle.
Roughing and finishing in one operation
- Roughing and finish grinding in the same cycle using grinding wheels with different grits.
- Distribution of the grinding process over several disks for workpieces with one complex geometry or sharp edges. The W axis moves to the different positions (software option: multiple plunge cycle).
- Oscillation loops for workpieces with high surface requirements.
More reliable – everything is linear
- Linear guides
Linear motors
Linear measuring systems- Resolution 0.00001
- Feeding accuracy 0.0001 No Backlash
Customer-oriented approach
- Automation and measuring stations can be integrated at any time. The layout and process can be customized.
