M Rotary Tables (or Round tables)

4th axis, multi-spindle

Multi-spindle rotary indexing tables from pL Lehmann permit simultaneous machining of different spatial angles as well as multi-side machining at every station.

Maximum flexibility during continuous use make our rotary indexing tables cost-effective, since high output can be achieved with little effort. Our rotary indexing tables are characterized by high angular accuracy in conjunction with minimal radial and axial run-out.

Our multi-spindle rotary indexing tables offer you the best possible solution even for difficult workpiece clamping situations.

Dimensions - M rotary

Standard spindle load

Drive data basics

All drive data of the pL LEHMANN rotary tables have been designed for the following
standard spindle loads in accordance with DIN/VDE 0520:
– For intermittent service S3 ED20%
– Backlash time of 1 minute

Any other conditions require the adjustment of the drive data
(acceleration, jerk limitation, rotational speed).

Reference values for duty cycle (Einschaltdauer, ED)

– For normal rotary table work such as milling / boring (mainly positioning): approx. 20 %
– For milling / boring in intensive mixed operation (positioning / feed machining): approx. ED 40 %
– For profile and depth grinding: approx. ED 60 %
– For engraving: approx. ED 80–100 %.
