RCC Series

Product catalog summary
Overview
The RCC series RollerDrive CNC Rotary Table offers a 90-degree index in 0.4 seconds. It features no backlash, high accuracy, and good efficiency due to its rolling contact mechanism, which eliminates wear and allows for preloadable high rigidity.

Features
  • No backlash and high accuracy.
  • Long-term use without mechanical maintenance.
  • Cost-effective compared to worm gear rotary tables.
  • Consistent long-term accuracy without backlash adjustment.

Specifications
The RCC series includes models RCC170, RCC200, RCC250, RCC320, and RCC400, with varying table diameters, center heights, and weights. Each model offers specific indexing accuracy, repeatability, and maximum table speed, depending on the motor used.

Options
  • Hydraulic clamper and built-in rotary joint options are available.
  • Output rotary encoder options include RON/RCN200 (HEIDENHAIN).

Cost and Maintenance
RollerDrive offers lower maintenance costs compared to worm gear models, with consistent accuracy over 5 million operation cycles. Cost simulations show that RollerDrive becomes more cost-effective than worm gear tables within three years.

Technical Specifications
  • Table diameters range from 170mm to 400mm.
  • Allowable payloads and torques vary by model.
  • Hydraulic and external rotary joint options are available.

Precautions and Service
  • Regular oil changes are necessary for lubrication.
  • Air purge outlets are standard to prevent rust and prolong electrical part life.
  • Consult Sankyo for continuous rotation applications to avoid overheating.

Global Network
Sankyo provides a global service network with contact information for offices in the USA, China, Vietnam, Korea, Taiwan, and Thailand.

Precautions/Service Network Notes on Air Supply CNC Circular Table comes standard equipped with an air purge outlet. (Use it to blow out condensation and coolant to prolong the life of electrical parts and prevent rust in the motor housing.) Supply clean air for the air purge by referring to the drawing shown below. Pressure setting: 0.02 MPa Air consumption: 15L/min CNC Circular Table uses an oil bath to protect the internal mechanisms and maintain reliability. Refill and perform oil changes regularly using the oil listed in the instruction manual. Grinding Machine Applications ■When used in...
