Since 1974 Swiss Rotary Table Technology pL LEHMANN has been developing and producing CNC rotary tables for over 40 years. – genuine SWISS QUALITY. The experience gained is incorporated into our products and services. With innovative CNC rotary axes, organized in a standard modular system, we want to meet the international needs for economical production of very small to medium-sized workpieces in the machining industry by satisfying individual requirements with appropriate combinations. We focus ourselves, our organization, resources and partnerships on this objective, immersed in a lean business system, where we avoid waste of any kind. In this way we make a significant contribution to protecting the environment and conserving valuable resources. Our goal is to take a stance in the manufacturing industry that is long-lasting, sustainable and innovative – unpretentious, reliable and down to earth based on the principle "What may be briefly of interest, but wrong in the long term, will be discarded" Today, pL LEHMANN is still a family-owned and managed company in the hands the second generation and present in over 20 countries. The company is committed to typical Swiss values: Depth of manufacturing – over 90% developed and manufactured in-house Product quality – reliable, durable, safe High-tech – Industry 4.0-compatible, ready to be automated Innovation – in tune with the times, adaptable, trendsetting Sustainability – long-term approach to business, environmentally conscious Basic values – honest, correct, fair
Flexibility: Modular system using standard elements ...
... with almost unlimited possibilities thanks
to zero point clamping on all elements
In all important markets, pL LEHMANN is present with
Workpieces are getting smaller and smaller, space is becoming more expensive. The pressure on costs and the "footprint" is increasing. At the same, saving energy is becoming more and more important worldwide – A compact pL rotary table leaves more space on the machine table, is lighter and saves energy.
Lot sizes are falling. The variety of parts is increasing. Product lifecycles are getting shorter. Cost pressures are rising. Means of production needs to become cheaper, be procured quickly and offer rapid adjustment – The pL rotary table will support you with this.
A particularly high power density is the result of a unique design:
Precision: not temporarily, but permanently. And good indexing accuracy alone is not enough either.
The solution from pL LEHMANN is:
The efficiency of the means of production is crucial. The pL rotary tables are designed for
pL LEHMANN supports you with comprehensive services throughout the entire lifecycle:
Quality is the result of sustainable and continuous improvement by consequently applying systems and principles:
The combiFlex® modular system allows a
large number of specific customer solutions with standard elements: proven,
cost-effective and quick.
One solution for six different CNC brands
All versions available with motors for FANUC,
SIEMENS, HEIDENHAIN, YASKAWA, MITSUBISHI and SANYO - without any changes in
dimensions, as standard.

You can convert your rotary table at a later point in time: for example, build a two-axis T rotary table from two EA rotary tables or vice versa, or convert an existing T rotary table to another version. Below, you will find some of the many possibilities:

TIME IS MONEY!
Example: 4 tools 11 positioning cycles per tool A) Increasing machine utilization h/year Time saving for each positioning cycle 44 positioning cycles per unit = 44 x 0.45 sec 15 units per h x 6,000 h/year B) Profit increase per year 550 h x € 60.00/h (machine-hour rate) ... thanks to short positioning time and quick clamping! |
