What is CNC roller cam rotary table:
Silvercnc adopts the roller CAM mechanism , one of the finest motion control mechanisms available. The unit is constructed from an input shaft(the roller gearcam) and a turret(output shaft) fitted with roller followers.The roller followers are preloaded against a screw-like input shaft to completely eliminate backlash. Our proprietary adjustment mechanism provides optimum preload. The roller followers planted in the turret use internal roller bearings to transfer torque while rotating. This ensures zero backlash, outstanding precision,and excellent efficiency without causing wear, while providing long-term consistent accuracy, it’s principle below:
Roller CAM driver 4 axis rotary table advantages:
The 4th axis rotary table is Widely used in large machining centers. Compared with other structures rotary table, the four axis have the following characteristics and advantages:
1, No backlash
Through the roller and CAM rolling contact, no forward and reverse back gap problem, greatly improve the roller CAM ultra-precision characteristics, reduce the rate of defects, improve the quality of precision machining technology is a breakthrough.
2, Ultra high efficiency conduction
Roller CAM type turntable in rolling way conduction, reduce wear, conduction efficiency is high, high speed operation, conduction efficiency is up to 90% above.
3, There is no thermal displacement
Even under high speed operation, reduce friction, reduce heat displacement, improve quality stability, reduce the rate of defects.
4, Free maintenance
Due to low abrasion and minimal aging, the initial precision can be maintained for a long time.
5, Life is long
Roller conduction mode, can reduce wear, long service life.
6, The brake performance
During the positioning of the brake, the disc surface will not shake from side to side, and the positioning brake will be kept within 2um, which can highly show the precision machining quality.
Models
Silvercnc has a full range of rotary tables to match different spec of machine tools.
It is very important to know about these parameters. Whether the specification is what you want according to the center height, reduce ratio, bearing capacity and braking force will judge by the parameters. You can also compare with other brands of rotary tables according to the repeatability accuracy , and decide which brand is best for you after asking for the price.Item | Roller CAM Driver | Worm Gear Type |

Choose a rotary table
There are several steps to confirm and choose a right rotary table :
(1) Comfirm your machine tool table size to determine the rotary table spec.
(2) Confirm the control system and model of your machine tools to determine what servo motor should equipped.
(3)Confirm the wiring , prepared by our company standard way or provided by the customer
(4)Confirm the braking way, select pneumatic braking or hydraulic braking
(5)Confirm the standard accessories, such as tailstock, base board ,mid-board, hydraulic station and so on
