Patented axis concept


The TSCHUDIN ecoLine  and proLine machines feature a new arrangement of the axes using a simplified concept (Patent EP 1330336 / US 7,223,159 B2).  The slide of the grinding wheel spindle (U-axis), the regulating wheel spindle (X-axis) and the work rest support (W-axis) are designed as independent CNC axis.

The TSCHUDIN proLine system additionally features a 4th CNC axis (Y-axis, Patent US 9,085,059) to move the regulating wheel vertically in order to eliminate the need to adjust the workrest blade height. Automatic compensation functions will keep the grinding geometry consistent throughout the entire grinding process.

The movement of the work rest support is carried out in a right-angle in relation to the U- and X-axis. The dressing diamonds are mounted onto the work rest support in order to allow the grinding- and regulating wheel to be profiled by CNC-control. This 3-axis concept completely eliminates the complex dressing units on conventional machine types. The patented movable workrest axis (W-axis) allows for additional grinding processes such as the highly efficient multi part grinding of several parts at a time or to split up grinding processes in the same grinding cycle to have both a rough and also a finish grind operation in one automatic set-up.

Additionally, the loading and unloading of the workpieces is always outside of the grinding zone, allowing simplified and safe automation or safe manual loading. This feature is highly attractive for those looking to meet health & safety obligations because otherwise the hand loading of parts to centerless grinding machines is dangerous.
