pL LEHMANN is a medium-sized business that has specialized in rotary tables for over 40 years – today is present in 25 countries. The company is committed to typical Swiss values + Product quality + Superior technology + Innovation and flexibility + Long-term, sound business policies The Lehmann Indexing / Rotary Tables are widely used on milling, cutting, grinding and EDM applications. The advantages of small size, high accuracy and unsurpassed spindle clamping capabilities are confirmed sales advantages for numerous OEM's & End Users worldwide.
CNC rotary tables are add-on axes and make machining centers, surface grinding machines, sinker EDM machines and many other machines into highly productive machining systems for manufacturing workpieces for various Fields of application.
Our CNC rotary tables impress on the basis of several factors, for instance, their power density, maximum accessibility - clamping workpiece and tool quickly increases productivity and accuracy - and a small footprint for optimal machining compartment utilization.
Our CNC rotary tables with accessibility from above open up possibilities, which have a positive effect on productivity and greater workpiece accuracy.
Our "CombiFlex" modular system permits conversion of our CNC rotary tables at any time, even after years. Thus, compared to our competitors, we need less space for our CNC rotary tables in order to achieve maximum modularity.
Well over 100 combinations are available with our standard CNC rotary tables. All gear units on our CNC rotary tables are preloaded to be backlash-free (PGD, preloaded gear drive) and thus ideally suited for true simultaneous operation.
Readjusting the gearbox backlash on our CNC rotary tables through radial adjustment of the worm gear guarantees long-term precision with minimal maintenance.
indexing tables (4th axis) are compact, flexible and can be installed in
almost any machining center. The better accessibility of the indexing tables
ensures a stable machining process and higher machining capacity.
The smaller the indexing table for the needed for the particular range of parts, the more energy-efficient it is.
This results from the smaller moving masses.
4th axis with rotoFIX clamping yoke for multiple clamping
With its multiple clamping capability, the rotoFIX clamping yoke system from pL LEHMANN permits machining of several parts, making it ideal for efficient volume production of series parts.
Please refer to
the EA-type rotary tables for exact technical data.
Dimensions, weights, accuracies and options for the rotoFIX clamping yoke system for multiple clamping can be found in the main catalog at Download.
M rotary tables (or round tables)
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.
4th + 5th axis, one spindle, "flying"
TF-type rotary tables (4th + 5th axis) are single-spindle, cantilevered dividing / indexing heads without a counter bearing and are especially well-suited for small workpieces with a cube size of approx. 100 mm to max. 250 mm.
Our dividing / indexing heads offer good accessibility for the smallest parts, making them ideal for machining of watch cases, medical device parts, dental implants and other small parts. Difficult-to-machine materials are processed especially precisely with our dividing / indexing heads.
Even when carburetors, turbines and similar parts are involved, our dividing / indexing heads are known for high machining capacity per unit time. Low-vibration clamping and machining are assured.
4th + 5th axis, one spindle, supported
Single-spindle, supported rotary tables (4th + 5th axis) with clamped counter bearing is one of over 20 standardized systems available within our product range. Our technical performance data for rotary tables cover a wide range of applications.
This rotary table is well-suited for small to medium-sized workpieces with a cube size of approx. 350 mm. The rotary table is ideal for machining automotive, aircraft and turbine parts as well as for general machining tasks. After all, maximum adaptability is required in contract manufacturing as it is no where else.
This rotary table, manufactured using superior technology, can largely fulfill you requirements for an all-rounder.
4th + 5th axis, one spindle, supported
These rotary tables, equipped with a clamped counter bearing, are well-suited for simultaneous clamping and machining of 2 to 3 workpieces. The rotary tables are ideal for machining of automotive, aircraft and turbine parts as well as for general machining tasks.
With a high machining capacity per unit time, these rotary tables permit the shortest possible tool lengths and shortest possible clamped workpieces for maximum rigidity. They impress with their low-vibration clamping and high-precision machining. Even difficult workpiece clamping configurations are possible with these rotary tables, which are just another standard product from us.
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
