Our spindle advantage:
1.Spindle runout within 0.001mm
2.12 months warranty
3.FAG/SKF imported bearing
4.3-8 years long life working spindle
Why choose us!
We have quality manufacturing/testing equipment like Studer S32 Swither made grinding machines and PLC controled testing station for all mechanical and electrical properties.
Over 12 years research and development and build up profound experience of motor spindles;
Keep optimizing structure, electrical properties, and convenient application in customers;
Key materials and components imported;
Steel:imported from Japan and Taiwan;(When we buy the steel back,we will stay them for at least 2 years.It will release the stress generated during processing and heat treatment.So our steel is stable.)
Bearing:SKF;FAG
University educated engineers and sales team;
Hands-on experienced engineers.
