CNC Rotary Table Systems from LCM
Since 1986 leading Italian Company L.C.M. srl has been manufacturing and distributing mechanical tooling accessories for machine tool engineering environments throughout the world and has built an enviable reputation for both product quality and customer service.
TDT Technology Ltd has recently entered into an exclusive UK sales and service centre agreement with LCM srl to market and sell their range of high-precision rotary indexing tables for use as 4th and 5th axis systems on machining centres, EDM machines and CNC milling machines.
Elements of Construction
L.C.M. indexing and rotary tables are made from a special alloy having high mechanical strength and features higher than steel or cast iron. The table load is reduced, resulting in less wear and thermal expansion of machine tool ball screws. Features include:
- Fully sealed sumps (covers) thanks to O-ring seals
- Forced pressurisation system
- Crossed Roller Bearings
- Cemented and hardened disk
During assembly, all L.C.M. rotary tables undergo a 40 hour test run to ensure final production accuracy. Tables then have a pre-load applied and under-go a final test inspection. Our sophisticated range of CNC rotary tables are the number one choice for machine tool manufacturers and precision engineers throughout the UK and broadly fall into two categories; those with Torque Motor or Standard Motor tables with hydraulic clamping and those with Mechanical Transmission tables, the worm-gear system with either Pneumatic or Hydraulic clamping.
Torque Motor System - High speed, zero backlash
L.C.M. produces a wide range of CNC rotary tables with torque motors. This technology allows LCM to build tables with similar working torque to the worm-gear system, but with higher rotational speeds. Another important advantage is the zero backlash providing high dynamic response and accuracy thanks to rapid bi-directional reaction. Liquid cooling increases torque and reduce thermal expansion and also being equipped with a directly mounted rotary encoder, these tables provide extremely precise position accuracy.
CNC Rotary Table TDE-T
- Horizontal positioning on machine table
- Torque Motor System
- Hydraulic clamping
CNC Tilting Rotary Table BRC-T
- Designed and made for 5 axis machines
- Torque Motor System

Mechanical Transmission Tables - Worm Gear System
L.C.M. produces a wide range of CNC rotary tables with mechanical transmission featuring the worm-gear system. This technology provides optimal rigidity and higher precision.
The Worm-screw - Uses a worm-screw made of cemented and hardened steel having a unique precision ground profile that guarantees a wide contact surface.
The Crown - Constructed from Bronal, this self lubricating alloy allows a preload to be applied to all LCM tables for increased dynamic accuracy and no backlash.

LCM Rotary Tables for EDM Machines
LCM is a market leader in manufacturing rotary tables for horizontal and vertical applications in EDM - Electric Discharge Machining, sometimes also referred to as spark machining. The unique combination of our precision rotary tables for EDM machines provides the capabilities to machine structures and complex shapes and contours which are impossible with conventional methods like turning, grinding or milling. LCM brings years of technical experience in high-precision prototyping, production engineering and micro-machining projects.
The LCM Way
Our high-precision CNC Rotary Tables provide customers with 4/5-axis machining capability & capacity and can be relied upon to deliver real gains in productivity by reducing machine cycle times. This is achieved by; fewer setups, faster work throughput and reduced operator interventions, ensuring you quickly maximize your return on investment.
