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.

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.

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.

“To further develop our capabilities in the important area of tooling trials we recently searched for a large, heavy-duty CNC rotary table that would provide the high-precision five-axis machining that we need, and that could be retrofitted to our DMG Mori DMC 1450 machine tool. After carefully assessing the alternative products from several major manufacturers, we came to the conclusion that an advanced rotary table from Lehmann best matched our demanding needs.

“Lehmann’s knowledgeable technical staff quickly understood our needs and suggested a T1-520530 TOP3 model, the largest 5th axis rotary table in the company’s range. As we were aware Lehmann’s excellent reputation, and as the T1-520530 TOP3 ticked all of our boxes, we were happy to place an order.

“Following the trouble-free fitting into our DMG Mori DMC and integration into the machine’s Siemens controller, our new rotary table soon began to deliver the levels of performance we were promised. The fifth axis provided by our Lehmann rotary table, and its impressive speed and precision, are now making significant contributions to our tooling machining trials.”

Lehmann has been at the forefront of the design and manufacture of high-quality, durable rotary tables for over four decades. The Swiss company’s expertise is reflected in the premium quality of the company’s products.

The CNC rotary tables are divided into geared and direct drive rotary versions and offer great flexibility. The company’s powerful designs offer many useful features, such as a built-in booster for spindle clamping, an internal monitoring system of all important functions and Bluetooth access for remote service.

Lehmann’s product line also offers a wide range of workpiece clamping possibilities, including options for fully automatic loading, and unloading by robots.

The T1-520530 TOP3 model, as installed in Exactaform’s DMG Mori DMC 1450 machine, is Lehmann’s largest available CNC, fifth axis rotary table and is able to accommodate workpieces of up to 600mm diameter and weighing up to 200kg.

Despite its generous capacity, the rotary table’s clever design means that it occupies a relatively small space within the machine tool. Given the demanding machining applications it is designed to undertake, the robust rotary table boasts high clamping forces of 2,000Nm rotating/7,000Nm tilting.

Aiding machining efficiency, the T1-520530 TOP3 provides 50rev/min rotating and 25rev/min tilting speeds. The advanced Lehmann rotary table is lifetime pre-loaded (adjustable) and backlash-free and delivers impressive accuracy and repeatability figures of 12a rc/sec and 2 arc/sec respectively.

The machining of complex workpiece geometries requires robust, flexible workpiece clamping and rapid, precise compound movements within the machine tool compartment. Throughout the world, and across multiple machine tools and challenging applications, Lehmann CNC rotary tables deliver all of these needs.

Lehmann’s products can be fitted to new machine tools or retrofitted to existing machines. In addition, the flexible rotary tables allow trouble free Integration into all known CNC control systems, including Fanuc, Siemens, Heidenhain, Haas, Winmax, Mitsubishi, Brother and Mazatrol.

After adding four-axis or five axis rotary table on the machine tool, multi axis machining can be realized, which can improve the machining efficiency and yield. With the improvement of manufacturing automation in China, the demand for rotary table increases significantly.

Now, I will introduce the situation of several rotary table brands in China. We will divide them into four categories: Europe andAmerica, Japan, Taiwan and Chinese brands.

Europe and America: the best selling brands in the Chinese market are Haas and Lehmann. Haas is mainly configured on its machine tools, other brands of machine tools are rarely installed. Lehmann is positioned at the high end and mainly cooperates with some high-end machine tools. In addition, it is also used in some occasions with high accuracy requirements, but the demand is small

Taiwan: TJR, Detron and GSA are the main brands, as well as DEX, Autocam and HW. These rotary tables are not only configured on Chinese brand machine tools, but also sold to end customers. Their precision is not high and their service life is not long, but they can meet the requirements when machining parts with low precision. Some users will consider these brands when their budget is limited. Among these brands, TJR has the best sales volume, with an annual sales volume of more than 10000 sets, because they have the most complete distribution network, complete models and cheap prices.Most importantl

China: there are many locally four-axis brands in China, such as Gutia,Silvercnc, Blue tech, CP and Deshu. The product quality of these brands is comparable to that of Taiwan. Due to more favorable prices and fast delivery, they have occupied the market of most Taiwan brands. The four axis of Chinese brands mainly adopt roller cam structure or harmonic structure. The wear resistance of roller cam is better than that of worm gear, with long service life and good accuracy retention. The price of harmonic reducer rotary table is low, which is suitable for 3C industry. These two structures meet the needs of the market and have been recognized by customers.

pL LEHMANN has developed a rotary table program optimized for measurement technology – the MQ series. The Swiss manufacturer offers two distinctly different models, the "Q-Line" and the "M-Line". While the "Q-Line" can be retrofitted to almost any measuring device at any time and automated if required, the "M-Line" is available from the measuring machine manufacturer (OEM) as a fully integrated model.

The Q-Line is ideal for stand-alone use. It is suitable for both new and retrofit equipment of coordinate measuring machines (CMM), for example, from all established manufacturers and also of other measuring devices (for roundness, contour, surface...), which it transforms into versatile measuring stations.

As an entry-level model – suitable for simple applications on the shop floor or in measurement laboratory – pL LEHMANN offers the manual, super-flexible rotary table MA-508.m Q. It can be combined with height, contour, and surface measuring devices and is recommended for run-out test equipment and coordinate measuring machines. Users can set different ratios to fast or slow in just a few steps. A smooth-running, sensitive handwheel makes it possible to approach any position very precisely and unerringly. A fold-out digital display shows the angular position with a resolution of 0.001°.

pL Q-Line rotary tables are optionally available in a housing made of aluminum (e.g. for transmitted light systems) or of spheroidal graphite iron (e.g. for CMMs). In addition, each unit is equipped with an emergency stop switch to meet the high safety requirements.
