Machine has the arrangement with traveling in longitudinal direction table and movable column traveling in cross direction bearing the wheel head.
Longitudinal table provides longitudinal feed when grinding, wheel head travels inside the column vertically.
Grinding wheel continuous dressing mechanism with rotary profile diamond roller is installed on top of wheel head. Coolant lubricant supply nozzles automatic travel mechanisms are installed on housing as the grinding wheel wears. Grinding wheel hydrodynamic cleaning nozzle is mounted on diamond roller continuous dressing mechanism of spindle carriage and it is travel with it.
Machine control is realized by CNC system from machine control panel located in front right of working zone. Working zone of grinding is guarded by protection of cabinet type in which it is foreseen to connect the exhaust system of pumping out coolant-lubricant aerosols. The front wall of protection has the movable opening door with plexiglass.
Profile surfaces grinding and also grinding wheel continuous dressing with automatic wear compensation is produced as per CNC control program (CP) in automatic cycle, at this the in-depth method of grinding is used.
Longitudinal table travel guides lubrication is automatic from host system.
Vertical and cross travel guides lubrication is consistent grease.
Lubrication of all ball screw pairs is consistent grease.
Spindles bearings lubrication is consistent grease for the entire service life.
