Eco/Pro Line

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 mm
  • Feeding accuracy 0.0001 mm
  • No Backlash

Customer-oriented approach

Automation and measuring stations can be integrated at any time. The layout and process can be customized.

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 centreless grinding machine 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.

X regulation wheel axis

Manual settings

1 – Configuring the workpiece superelevation
2 – Setting the height of the dressing tool

4 axes
Full automation

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.
