【Main use】
This machine is designed to grind cylindrical worms such as ZA, ZN, ZI profile, and to grind trapezoidal screws as well。【NC system configuration】
【Working accuracy】
working accuracy
when thread start=1(GB) Grade 5
when thread start≥2 Grade 6
when grinding ACME screw within 6mm pitch(GB) Grade 6
【Technical characteristics】
1、Work spindle speed is stepless due to appliance of frequency converting technology; Workpiece indexing is done automatically; Work spindle center is fixed or dead type to minimize the effect of work spindle accuracy。
2、Thread pitch change is done by exchange gears. A straightedge located at table side can correct accumulated pitch error。
3、Both work table and wheelhead travel along V-and-flat guideways to make a flexible and smooth running。
4、Grinding wheel spindle is supported by high-grade imported rolling bearings, having high rotary precision, good rigidity and convenient maintenance。
5、Wheel dressing is done with a hydraulic automatic wheel dresser, through profile modeling, dress grinding wheel into ZA, ZN and ZI worm profiles。
6、A full-closed cover and an imported oil-mist extractor are provided with the machine to improve working environment。
7、If a CNC wheel dresser adopted, the machine can realize ZA, ZI, ZN, ZK and ZC1 worm profiles。
