1. Introduction:

The spindle has a ceramic spindle shaft to decrease the moving mass and increase the shaft stiffness for better dynamic stability. The spindle employs a built-in linear motor to provide direct drilling motion to move the shaft along the axis, and a permanent magnet DC brushless motor to rotate the spindle shaft. The linear motor is coupled to the shaft by a combination of an air bearing and a magnetic thrust bearing to reduce the size of the thrust area for better dynamic stability and reduction in stresses of material. A double gripping centrifugal chuck is mounted in the hollow ceramic shaft, and reduces drill bit runout.

Innovacera's advanced ceramic materials are used in applications including: computer peripherals, mobile communications, medical, oil and gas, chemical processing, power generation, impact protection/armor, textile, faucet, led lamp, car,electronic, mechanical, automotive, valve and pump, analytical instrumentation and many other industrial engineering applications . Components are manufactured to our customer's specifications.
