Complete set of ball screw pro
- Main use
- NC system configuration
- Working accuracy
- Technical characteristics
- Main specification parameters
【Main use】
This machine is mainly used for grinding various Whitworth threads, Acme screws and ball-screws precisely。【NC system configuration】
【Working accuracy】
ball-screws: P3 (GB/T17587.3-1998)
Acme screws: P6 (JB2886-92)
【Technical characteristics】
1、The sliding guides are adopted on work table to get smooth movement and light running
2、The wheel spindle is supported by precision hydraulic bearings, having a good rotary accuracy and loading capacity。
3、The various Acme or circular threads can be ground with the help of the different types of dressers
4、The change of pitch is obtained with change gears.。The accumulative pitch error is corrected by means of the correction bar in the front of the table
