• 1. Adopting precision steel ball retainer, the rotation precision is higher, which ensures the rotation precision of the electric spindle during high-speed grinding.
• 2. Fan cooling, no water pipe, direct connection, more convenient.
• 3. The spindle is lubricated with 200 degree high temperature grease.
• 4. The body is made of greased stainless steel to keep the body clean and not easy to rust.
• 5. 24,000 ultra-high speed rotation per minute, running smoothly, running sound is only 50-60 decibels, low noise.
• Note: The default setting of the spindle is 400HZ.
