【Main use】
The machine is mainly used for precisely grinding thread grooves of ball-screw
【NC system configuration】
【Working accuracy】
The accuracy of screw ground is up to grade P3 specified in GB/T17587.3-1998【Technical characteristics】
1、Table moves along plastic-coated rails,and wheelhead travels along rolling guide-ways,ensuring a stable and smooth movement。
2、Supported by hydrostatic bearings,the wheel spindle has characteristic of precision & heavy loading capacity。
3、Wheel dresser, which can feed automatically & manually,dress the grinding wheel into double-arc profiles with corresponding copying plates。
4、Pitch change is done by exchange gears. Pitch error is corrected by a correction bar mounted in the front of the table
