SEMIAUTOMATIC CREEP FEED SURFACE PROFILE GRINDING MACHINE WITH CNC OSH-221F3
DESCRIPTION
Semiautomatic creep feed surface-profile grinding machine with CNC model OSH-221F3 is designed for creep feed grinding of profile surfaces and deep slots of parts made of heat-resistant and other hard-to machine materials by abrasive grinding wheels. Machine has eight programmable coordinates.
Number of controlled coordinates and axes
X-longitudinal table travel
Y-vertical wheel head travel
Z-cross column travel
V-vertical travel of slider dressing mechanism
Q1,Q2- vertical coolant lubricant nozzle ( right,left)
Sp1- grinding wheel rotation frequency
Sp2- diamond roller dressing mechanism rotation frequency
Machine field of use – enterprises of serial and large-scale manufacture.

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.
