dmg mori rotary table factory

The DMF series models are traveling column machining center equipped with a NC swivel rotary table to perform high-efficiency 5-axis machining of long workpieces. The models employ a polymer concrete bed and a heat-symmetrical traveling column, ensuring high-rigidity and stable machining for a long term.

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. Monitoring and reporting of machine status is performed by DMG MORI’s Messenger software. (Photo courtesy of DMG MORI.)

KOMA Precision, Inc. has updated its DMG-Mori Seiki Tsudakoma Rotary Table Selection Guide to include Tsudakoma"s RNA Series 4th axis rotary table and the Tsudakoma RTT-111, CA, a drop trunnion rotary table designed to utilize a variety of workholding systems.

The DMG-Mori Seiki Tsudakoma Selection Guide is the result of an effort to simplify the selection of Tsudakoma rotary tables specially suited to fit within the working envelope of the listed DMG-Mori Seiki machining centers. In addition to the standard rotary tables shown in the booklet, productivity enhancements include encoders, tailstocks, support spindles, faceplate and rotary joint options and high strength triple-walled stainless steel cabling packages.

"For almost 30 years KOMA Precision has been a source in machine tool productivity innovations. With over 30,000 rotary table installations, KOMA is the largest distributor of Tsudakoma NC rotary tables and indexers," said William Meo, President, KOMA Precision, Inc.

Technitron (Cincinnati, OH) supplies complete turnkey installations and custom interfacing services for Hardinge 4th-axis rotary tables and indexers. They have experience in 4th-axis and dual-axis tables and indexers for vertical and horizontal machining centers including machines with linear and rotary pallet shuttles. ?Their knowledge and expertise with non-Hardinge brand machine tools and various CNC controls will expedite the quoting process, delivery and installation for 4th-axis rotary applications here in North America,? states Mike Levanduski, Director of Sales at Hardinge Workholding.
