5 Axis Rotary Table

CNC rotary table  China manufacturar 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.

Silvercnc has a full line of 5 axis tilting rotary tables to match different spec of machine tools.

T100  and RT 170 are most suitable for drilling and tapping machines

RT200 is most suitable for 850 VMC

RT250 is most suitable 1100 VMC

RT500 is most suitable HMC

Whether the specification is what you want, please confirm the center height, reduce ratio, bearing capacity and braking force 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.

There are several steps to confirm your rotary table requirement:

(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

(6)Confirm the color and logo , standard color and logo or customize
