High Rigidity 4th Axis CNC Rotary Table for Milling Machine Turntable
CAM type zero backlash CNC rotary
Cam-roller transmission structure is adopted inside the product.
CAM shaft needle roller bearing precompression no gap rolling drive.
No sliding friction, continuously maintain no gap characteristics.
High accuracy of forward and reverse motion repetition.
High rigidity, high efficiency.
Does not cause poor accuracy due to temperature rise.
No need for regular calibration and adjustment
- Working principle and characteristics of cam-type CNC turntable
- Principle of preloading
The CAM type NC turntable has higher precision than the traditional worm gear type turntable
Operating characteristics of degree, high speed, zero back clearance and heavy load. Input axial cams
The needle roller bearing on the output shaft turret of the constant speed driving curved surface is precompressed rolling contact transmission,
To achieve zero back backlash and higher speed operation, due to the rolling transmission almost zero
Friction movement, so that the mechanism can maintain no backbacklash transmission, high precision positioning, and no need
Regular calibration and adjustment work should be done. Lattice CAM type CNC turntable, Han out of the shaft use
The large bearing is arranged on the round outer wall of the shaft, and the two ends of the CAM input shaft are set with double bearings.
It also enhances the stability and load capacity of the turntable, and can better cope with the processing
High speed and heavy cutting force, improve machining accuracy, efficiency and reduce costs.
