dmg mori rotary table made in china

In Booth S-9092, CNC Indexing & Feeding Technologies (Mason, OH) proudly announces their new partnership with TJR (or Tan Jia) Precision Technology Company, Ltd. (TJR; Taichung City, Taiwan), a well-established supplier of rotary tables to machine tool OEMs such as Okuma, Doosan, DMG Mori, Mazak, and Tongtai. “The new partnership allows us to supply the most technically advanced rotary tables in the industry, with special emphasis on direct drive and 5C collet 4th-axis series units,” explained Steve Smith, the president of CNC Indexing & Feeding Technologies.

The company originated as a rotary table sales and service agent prior to establishing TJR as an OEM in 2009. After much success, they grew to having the largest market share of machine tool accessories in China. Today, TJR is a top OEM with offices all around the world. Their rotary tables are built with high quality features, such as an anti-wearing worm gear and shaft made of high tensile brass for durability. Their encircling braking systems use a large clamping range to prevent displacement during heavy-duty cutting. For tilt rotary tables, TJR offers a 2+1 independent braking system and large diameter radial and axial preloaded bearings for rigid support during 4th- and 5th-axis cutting on both single and dual arm rotary tables. A three-year parts warranty is standard for all new TJR rotary tables.

New to the U.S. market is the DMU 75 MonoBlock, a five-axis machining center that balances a relatively compact footprint (less than 86 square feet) with a relatively large work envelope for parts measuring as large as 33 inches in diameter and weighing as much as 1,322 pounds. The demo at Davis emphasized the accessibility of the configuration (it enables loading with a crane) and the flexibility of the swiveling rotary table. The machine was shown with a FANUC control unit using the Celos interface and Mapps digital operating system.

Also making its debut was the DMU 90 P DuoBlock, a five-axis machine configured with a rotary head over a rotary table. The “P” designation indicates that it is powered for heavy-duty machining of large workpieces as heavy as 3,970 pounds. Its stated positioning accuracy is 4 microns. X-axis travel measures 35.4 inches. This machine is described as “an economical entry into machining of die/mold work and aerospace structural components.”

Three versions of the CMX 1100 V machine were on display to show how this platform can be “packaged” for the various needs of job shops looking for a boost in their vertical machining capability. The CMX 1100 V is the largest of the machines in this series and the best-selling size (the CMX 600 V and the CMX 800 V have smaller tables). The version shown here represents the “value” package with the basic features included to give an entry-level machine with 55 inches of X-axis travel and a 12,000-rpm spindle. The “performance” package displayed nearby looked nearly identical, but features a 15,000-rpm spindle and is prepped for on-board probing, coolant and filtration options plus automation. The CNC has more advanced features as well.

DMG MORI’s Messenger software is a complete data-collection and machine-monitoring system. Although it is designed to leverage the copious data generated by the company’s machine tool products, the system can accept data from any machine in the MTConnect format.

The tour of DMG MORI’s North American manufacturing facility was a bonus for Davis Technology Days attendees. This picture was provided by the company to illustrate the capability of this factory. It manufactures and assembles different models of the NHX horizontal machining centers as well as the CMX 1100 V vertical machining center. Castings for these machines await processing in the facility.

The facility employs automated production methods such as production cells, palletized systems and robotics. DMG MORI’s cell control software manages all of the machining programs, production schedules and provides control of production.

Rotary table in market mainly includes 4 kinds of mechanism that is worm gear, roller cam, DD driver and harmonic structure. The following is the introduction:

1. worm gear: it’s one of  the most popular structrue in NC rotary table  because of its irreversibility and costs.The worm is generally made of bronze, but the wear resistance is poor. In order to improve the service life, some manufacturers use the alloy steel.

3.DD motor: it’s the most efficient rotary table with the highest precision. It has the highest precision because it has no mechanical structure, which is directly driven by motor , no reducer. It has high technical difficulty and high price. It is generally used for five axis machine tools.

DMG MORI’s 5-axis machines use large-diameter bearings in the swivel rotary table to ensure enough rigidity of the single support table. We also offer machines with double support tables for customers requiring even higher rigidity.

This DMG GILDEMEISTER DMU 50 ecoline Vertical Machining Center was made in the year 2011 in Poland and has 24592 production hours, of which 9276 are spindle hours. It is equipped with a DMG SLIMline control unit and has 3+2 axis. The machine has a spindle speed of 8000 rpm.

An integral part of the Pfronten open house is the annual press conference and this year things were a little different. DMG Mori president Masahiko Mori usually attends in person, chairing the conference with fellow Executive Board member Christian Thönes, but this time he made a ‘virtual’ appearance, via satellite video link live from Japan.

Dr Mori emphasised DMG Mori’s significant worldwide presence with 165 sales and service locations in 76 countries, 14 production plants and nearly 12,500 employees. For greater operational efficiency, he advised that the company had recently realigned its worldwide sales and service structure: since January, DMG Mori Aktiengesellschaft, with its headquarters in Bielefeld, Germany had assumed responsibility for markets in Germany, EMEA, India and China; whilst DMG Mori Company Limited, based in Tokyo, Japan was responsible for its home market, the USA, Korea, the ASEAN region and the Americas.

As part of the rationalisation process, Dr Mori announced that three facilities are to close: the Dixi factory in Le Locle, Switzerland with technology being transferred to Pfronten and Iga, Japan; the Chiba plant in Japan which will also be absorbed into the Iga factory; and the Shanghai facility in China. He also advised that the Tobler factory in Louvres, France is no longer under DMG Mori ownership.

Despite a challenging market environment, business held up well in 2016 for DMG Mori. An order intake of €2,369.9 million signified a new record high, although sales revenues of €2,265.7 million were slightly below the previous year (€2,304.7 million).

A DMG Mori Pfronten open house simply wouldn’t be the same without new machine introductions and despite the shift in emphasis, three world premieres were unveiled at the event.

With the latest incarnation, DMG Mori has combined a modern design with user-friendly operation. The large 876mm wide smooth opening door enables unrestricted access to the machine even when automated systems are used and the table has an ergonomic loading height of 800mm.

Travel paths of 650mm x 520mm x 475mm and the capability to accommodate workpiece weights of up to 300kg means the DMU 50 can process a wide range of components and it’s new NC swivel rotary table with an enlarged swivel range of -35°/+110° boosts this versatility.

Rapid traverse of 42m/minute and 30rpm in the swivel rotary axis provide the dynamics necessary for effective five-sided/5-axis simultaneous machining. Motor spindles up to 20,00rpm are available as well as an option for an expanded tool magazine with up to 120 pockets. There are 30 tool pockets in the standard version.

A one-piece machine bed, integral cooling of guides, drives and table bearings, direct drive ballscrews and direct path measuring systems in all five axes round off the machine’s high specification.

Through its Siemens 19-inch multi-touch control, the ergonomic CLX 350 offers users rapid operation in a compact package. In addition, the new 19 inch DMG Mori SLIMline multi-touch control plus software solutions such as ShopTurn for fast, simple and error-free programming on the machine and advanced simulation possibilities, round off the offer. What’s more, DMG Mori technology cycles, including Easy Tool Monitoring, make working with the CLX 350 even easier.

Laser texturing of geometrically defined surface structures, such as those found on the fittings of cars or electronic housings, is more environmentally-friendly than conventional etching, offering freedom of design and optimum repeat accuracy. The compact (8m² footprint) Lasertec 75 Shape joins the ranks of DMG Mori’s laser texturing portfolio and is equipped with a 100W fibre laser and the Celos machine interface.

The core of the machine is the 100W pulsed fibre laser and 3D processing optics with an F-Theta lens. The laser provides the power for efficient layer-by-layer 3D laser material ablation and, in combination with the NC swivel rotary table, offers contour-parallel laser shaping for rapid, trouble-free laser texturing, even in 3D free form areas.

From a control perspective, the Lasertec 75 Shape utilises the Siemens 840 D solutionline, which when combined with DMG Mori’s Celos interface enables complete integration into a company’s production system. User-friendly and application-specific Lasersoft software is also included.

Underpinning the Pfronten open house this year was DMG Mori’s Smart Factory and Industry 4.0 technology, supporting customers via software through every process step.

DMG Mori is expanding its digitalisation drive through new Celos solutions, exclusive technology cycles and powertools as well as start-up methodologies for digital production. The trend towards networking machines, products and services to form digital process chains is relentless. Consequently, sensors and software are becoming vital, particularly in the machine tool industry. DMG Mori’s primary objective is to offer added value for customers, supporting them in the early stages of their digitalisation process through to full implementation if required.

This is demonstrated via 26 exclusive DMG Mori technology cycles for rapid and simple shopfloor programming as well as new Powertools for the automatic creation of programs. Similarly, the company is reinforcing its app-based control and operating system, Celos with the addition of new, targeted applications and solution packages.

The Celos interface is integral to DMG Mori’s digitalisation plans. More than 100 machines in the company’s portfolio already ‘speak’ Celos and the number is rising. Customers operating in a wide variety of industries can monitor, analyse and optimise the processes in their Celos machine via app-based operation. There are now 26 Celos apps.

In accordance with this classification, DMG Mori’s spectrum of digital products and services is orientated towards three top level stages of factory automation: Celos Machine; Celos Manufacturing – enabling intelligent workflow; and Digital Factory – the wider production environment.

To assist with this element of its business, DMG Mori has acquired an interest in start-up company ISTOS (Innovative Software Technologies for Open Solutions) based in Düsseldorf. ISTOS will be developing digital projects for DMG Mori, its customers, partners and suppliers.

In collaboration with DMG Mori Software Solutions GmbH, ISTOS will also be supporting customers with fully integrated digitalisation systems. The first specific products and solution approaches are expected to be presented at EMO later in the year.

Robo2Go is a mobile automation system introduced by DMG Mori specifically for turning centres. Controlled via Celos, it can be used with up to four machines.

DMG Mori continues to develop its additive manufacturing technology and a recent announcement that it now has a 50.1% majority shareholding in Realizer GmbH based in Borchen, Germany will strengthen its offering.

DMG Mori already has extensive know-how in the field of laser deposit welding with powder nozzles through Sauer GmbH and now, through Realizer, it will have access to Selective Laser Melting (SLM). In this process, the material is applied in powder form in very thin layers and melted by laser.

As a pioneer of the powder bed process, Realizer has consistently developed SLM technology over a 20-year period, elevating it to mass production levels. In future, development and assembly will take place in Borchen and at DMG Mori in Bielefeld. The two leading production technologies enable complex, metallic components to be produced from powder.
