Product Features
Arbitrary indexing angle
Unlike the fixed indexing of the CAM indexer, the hollow shaft rotary table is driven by a servo motor and controlled by PLC programming to achieve arbitrary angle indexing.
Large diameter hollow shaft
The output shaft of the Hollow shaft rotary table is a large-diameter hollow shaft (the maximum bore diameter can reach 270mm), which provides convenience for equipment integration and solves the problem of cable entanglement during operation.
Strong carrying capacity
The Hollow shaft rotary table uses crossed roller bearings, which can have a greater load-bearing capacity and anti-overturning torque than ball bearings at the same size.
High precision and rigidity
Pre-tensioned installation is used to eliminate clearance; The rollers are in linear contact with the raceway and the force deformation is small, allowing the Hollow Shaft Rotary Table to achieve high repeatability of 10 arc sec. The design of the rollers in line contact makes the system extremely rigid and can effectively suppress vibration during processing.
