The robust geared rotary tables of the 500 series are extremely flexible to use and, thanks to the combiFLEX® modular system, can be converted or extended at any time to meet new machining tasks. The rotary tables are not only suitable for positioning operation, but can also be used for short simultaneous machining operations. The preloaded gear and the powerful bearings allow high long-term accuracies as well as large spindle loads. The maximum clamping force of up to 7,000 Nm leaves hardly anything to be desired.

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.

Word soon spread within the F1 community regarding CNC Techniques range of capabilities and Mr Eden’s fledgling business quickly established a loyal customer base. The mainstays of CNC Techniques machining capabilities are its high-performance Hurco 3-axis and 5-axis machine tools. To provide an additional 2-axes to the company’s 3-axis machines and to add greater machining flexibility, CNC Techniques recently invested in a rotary table solution from Lehmann.

“Although we are kept busy throughout the year, our workload more than doubles in the traditionally busy F1 months of December through to February. Therefore, at this time of year, apart from working around the clock, we need to work smarter and employ equipment that provides greater flexibility. The need for machining flexibility and the requirement for an additional 2-axes on our Hurco VMX 30, 3-axis machining centre, were the major motivations behind the recent rotary table purchase.

“Even though I was aware of the excellent reputation of Lehmann products, I was open to the idea of purchasing alternative brands of rotary tables. Although, when compared to the indifferent response I received when I contacted some other manufacturers, the reaction I had from Lehmann was first-class. All of my questions were answered quickly and several constructive suggestions were made by the company’s technical staff.

“In addition to giving us the ability to achieve five-sided machining in a single setup, I was assured that a Lehmann rotary table would withstand the high forces involved in machining exotics and also deliver the standards of precision we need.

“The installation of the rotary table was carried-out by a couple of knowledgeable technicians who made all of the connections to our Hurco VMX 30 3-axis machine tool’s control system,” he adds.

“Then, whilst observing the rotary table’s try out I realised how easy it was to operate. We now use the rotary table along with our Lang Technik workholding. In addition to standing up to the machining forces used to machine exotics, the rotary table is simple and fast to operate and is making a significant contribution to our 3+2 axis machining capabilities.”

Increasingly, users of 3-axis VMCs are fitting Lehmann CNC rotary tables to their machines as they represent a cost-effective means of entry into 5-axis machining. When mounted in a VMC, the tables are able to deliver a tilting A-axis and/or a rotational C-axis.

Given the compact nature of Lehmann CNC rotary tables, they allow workholding devices to be located alongside them inside VMCs. If required they are able to remain in the machine, or they can be quickly removed and later replaced according to the machining jobs being carried-out.

By locating workholding beside the a compact Lehmann rotary table, a virtual 6-axis condition can be achieved. For example, following the five-sided machining of a workpiece held on the rotary table, without a break, machining can be undertaken on the next workpiece in a batch that is held in the neighbouring workholding.

As floor space is at a premium in most machining environments, mounting a CNC rotary table inside an existing 3-axis VMCs provides a major advantage over purchasing a large 5-axis machine tool. In addition, the cost of the table is a mere fraction that of an expensive new machine tool

Lehmann has been designing and manufacturing high-quality rotary tables for more than 40 years. The experience and expertise gained over this time is reflected in the quality of the company’s advanced products and in its exemplary levels of service.

To minimise parts and to enable the delivery of Swiss quality at a cost-effective price, Lehmann rotary tables are based on an innovative, standard modular system. This highly efficient approach allows a wide range of CNC rotary table options to be made available to meet all customers’ diverse needs.

A recently installed pL LEHMANN CNC rotary table is enabling a Bostomatic high speed milling machine belonging to Thomas Keating Toolmaking Ltd to perform highly efficient 5-axis machining.

Due the demanding nature of the machining undertaken when manufacturing scientific instruments, rather than invest in a 5-axis machine tool, the company recently took a more ‘bespoke’ route. Having decided that a pre-owned, 3-axis Bostomatic milling machine had the ideal, stable machine structure to support the company’s challenging 5-axis work, the machine was comprehensively re-built and fitted with a Heidenhain TNC640 5-axis controller by ACC Systems Ltd. To complete the Bostomatic’s conversion to 5-axis work, company Managing Director, Dr Richard Wylde searched for a suitably accurate and flexible CNC rotary table. The answer was found in an advanced pL LEHMANN T1-507510.LL TAP1 model.

«We are constantly searching for ways to improve our capabilities, hence the recent Bostomatic machine tool, Heidenhain control and Lehmann rotary table purchase. When judged against the alternatives that I considered, the pL LEHMANN T1-507510.LL TAP1 rotary table best met our exacting technical criteria and also represented excellent value for money. Now installed in our re-built Bostomatic machine, it is in daily use and is helping us to perform exceptionally accurate and highly efficient 5-axis machining.»

«In addition to the advantages the rotary table has provided to our tool making activities, it has proven extremely useful when we manufacture our high-precision scientific instruments. For example, we are currently involved in the production of the next generation of satellite-based weather prediction instruments. The precision 3+2 axes capabilities provided by our Lehmann rotary table have been invaluable when undertaking this challenging work.»

«Equally, when recently manufacturing thin, metal film coated dielectric mirrors for use in Dynamic Nuclear Polarization instruments, the use of our new rotary table enabled our complex 5-axis machining tasks to be performed with ease. In addition to delivering 5-axis capabilities our new Lehmann rotary table has considerably increased our manufacturing speeds.»

«So successful has our use of a Lehmann rotary table been when used in our Bostomatic machine tool, we are currently in the process of purchasing another Bostomatic machine that will be fitted with a second Lehmann rotary table.»

t is estimated that 90% of machining procedures carried out by 5-axis machining centres are basic five-sided processes. Therefore, the fitting of a CNC rotary table, that costs a fraction of the price of a 5-axis machining centre, to an existing 3-axis VMC, represents an excellent alternative way of achieving 5-axis capabilities. It also results in a rapid ROI.

pL LEHMANN’s advanced CNC rotary tables are based on an ingenious modular design concept that enables a range of high-quality standard components to be used to produce a comprehensive series of product variants. Each of the company’s rotary tables can be further refined according to customers’ specific needs. This innovative approach provides pL LEHMANN’s customers with several major advantages. For example, rather than accept a ‘nearest-fit’ rotary table solution, pL LEHMANN’s customers are able to receive a CNC rotary table that exactly matches its intended use. In addition, efficiencies gained by pL LEHMANN’s modular approach allows the delivery of Swiss quality products at affordable prices.

The advanced designs and relatively small footprints of pL LEHMANN’s rotary tables ensures that, when installed in VMCs, such as Thomas Keating Toolmaking’s Bostomatic machine, they occupy minimum bed areas. As well as freeing-up room for the fitting of additional vices and other workholding devices, the space-efficient nature of the rotary tables means that, when a VMC is not undertaking 3+2 axis work, they are able to remain inside the machine when 3-axis machining is being performed. Furthermore, the compact size of pL LEHMANN’s CNC rotary tables helps to take full advantage of the available working volumes of the machine tools that they are fitted to.

pL LEHMANN’s heavy-duty rotary tables have earned a global reputation for their outstanding quality and longevity. The company’s robust products benefit from excellent clamping torque, load weight and accuracy specifications. In addition, pL LEHMANN CNC rotary tables are able to interface with the vast majority control systems.

For more than 40 years, the Swiss company pL LEHMANN has been building compact, high precision CNC rotary tables. The powerful design offers many special features, like a built-in booster for spindle clamp, an internal monitoring system which checks all vital functions, including Bluetooth accessibility for remote service. The product line also offers a wide variety of workpiece clamping options, including options for fully automated robot loading and unloading. New: “direct drive” rotary axis for Millturn functions.

With innovative CNC rotary tables, organized in a standard modular system, the company strives 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.

Complicated workpiece geometries require multiple and flexible workpiece clamping and motions in the machine compartment. Based on a high level of standardization, pL LEHMANN is able to offer an appropriate and economical solution for the most varied of applications. Short setup times increase productivity and the degree of utilization. At the same time, the user has the ability to automate one step at a time: e.g. starting with manual loading, progressing to simple linear feed systems and ultimately to fully automated production with robots. With interfaces for different clamping systems, supplemented with the appropriate clamping cylinders and rotary unions and possibly even stroke and pressure monitoring, a wide range of modules is available.

With just four basic sizes of rotary tables covering from Ø100 to 500 mm face plates, pL Lehmann cover the performance range required by most machine shops. Rotational speeds up to 210 rpm provide a 90° index in just 0.21 seconds (Direct Drive Series 900 provides up to 5,4o0 rpm). A feed torque of up to 850 Nm, combined with heavy duty bearing, allow high spindle loads up to 1,600 Kg for aggressive cutting strategies.

pL Lehmann"s goal is to maintain a sustainable, innovative stance in the manufacturing industry- basing their principles on the philosophy "What may briefly be of interest but in the long term is untenable will be excluded from consideration". By focusing on organisation and partnerships to create an environmentally friendly workspace in which waste of any kind is avoided, significant contributions to protect our natural world and conserving valuable resources are achieved.
