Why choose us
1.EEJA spindle motor Advantages
★Positive air pressure inside is applied to seal the products so no foreign materials can find ways to enter the spindle bodies.
★Water route is designed inside for cooling and no over heat will happen in working.
★ The bearings are from famous brand in Japan or Germany.
★The steel of shaft and other key components are from Japan.
★ The motor wires are well treated for high property of electrical resistance.
★ All these result in high quality of long life, precision, high speed, low shaft run-out, etc.
★ The whole manufacturing processes have been designed, tried and improved again and again to meet the high precision requirement like the master shaft diameter in the tolerance of +/-0.001mm.
★ World class equipment is used for manufacturing and testing. Clean room is used for assembly.
★The team of designing and manufacturing are well educated, trained and have built up their robust experience in their work.
2.Our company advantages
First, our steel has been forged under high temperature. Generally, we will put the steel for 2 years of natural aging to release stress and heat energy.
Secondly, the runout of our spindle rotor is less than 0.001mm, so our spindle service life is generally more than 3 years.
Thirdly,the wiring of our spindle is copper plated with silver, and the insulation effect is very good.
Finally,our spindle bearing is after multiple tests, we finally choose the imported bearing FAG/SKF.
We have quality manufacturing/testing equipment like Studer S32 Swither made grinding machines and PLC controled testing station for all mechanical and electrical properties.
