Hermle Showcases New Approach to 5-Axis Machining at Westec 2004 Advanced Productivity Exposition

Franklin, WI (For Immediate Release) - - - Hermle Machine Company, in association with software developer DELCAM International, will present a new addition to the Hermle product line for applications requiring full simultaneous 5-axis and/or 5-sided machining: the C 30 U Dynamic.(TM) Utilizing software from DELCAM International, the C 30 U will offer visitors the opportunity to view the machining of complex aerospace parts in booth #2745 at the upcoming Westec 2004 Advanced Productivity Exposition. Developed in response to the ever-increasing demand for 5-axis performance, the C 30 U is designed for precision machining in modern alloys and non-traditional materials.

The C 30 U Dynamic utilizes Hermle's patented gantry design in combination with a 630 mm diameter tilting rotary table capable of simultaneous machining of work pieces up to 800 mm. Production capability is enhanced by a rotational speed of 65 rpm in the C-axis (360°) and up to 55 rpm in the trunnion type A-axis (+30°/-115°).

For increased production of smaller sized parts, the new C 30 U Dynamic can be equipped with a 280 mm diameter rotary table mounted on the tilting trunnion type A-axis. The rotary table operates at speeds up to 40 rpm (360°), and the tilting A-axis (± 115°) can be actuated up to 55 rpm.

Faster production potential is assisted by the standard rapid traverse rate of 45 m/min in the X-Y-Z axes in the standard machine, and 60 m/min in the Dynamic version. Acceleration is 6 m/s2 (.6G) and 10 m/s2 (1G), respectively.

Standard spindle speed of 10,000 rpm, with optional 18,000, 28,000 and 40,000 rpm speeds, extends the range of capabilities from high torque, hard metal operations to high-speed machining of complex parts.

Axis travels are 650, 600 and 500 mm in the X-Y-Z axes, respectively. C-axis actuation utilizes a direct drive torque motor (630 mm design only), and both A and C axes feature Hermle's patented drive system.

Thirty-two (32)-tool pockets are standard. Optional magazine extensions can increase capacity to 117 or 194 tools, with a chip-to-chip tool change time of 4.5 sec.

Modular Design for Maximum Flexibility

A wide range of options can be incorporated to suit specific applications or production systems.
o Alternate clamping systems including SK 50 or HSK A 100 can be integrated into the rotary tables.
o Work holding can be accomplished through a variety of means including T-slots, zero-point clamping systems, palletizing and other means.
o A variety of coolant options and filtering systems are available including turbo filter, paper ribbon filter, or sieve basket.
o An optional graphite machining package provides full capability for electrode production or composite material machining.

New Pallet Change Option

For manufacturing cells or fully automated operation, the C 30 U Dynamic can be equipped with Hermle's newly designed PW 500 or PW 630 pallet changers. Built on a mineral casting base to eliminate thermal distortion, the pallet changer is isolated from the machine to ensure vibration-free operation.

Hermle's unique design provides operator accessibility to the machine workspace without impinging the pallet set-up. A large door opening permits multiple loading options including gantry or crane.

The unique pallet clamping system incorporates a modified cone-shaped element for pre-centering, and clamping balls for precision positioning. A chip blowing system eliminates the possibility of contamination in the clamping area.

Customers considering the addition of a pallet changing system at a later time can specify a "pallet ready" version of the C 30 U Dynamic that permits fast, easy installation of the pallet changer at a later date.

Designed for the Present... and the Future

The C 30 U Dynamic represents the cutting edge of a new generation of machining centers designed to excel in today's production environment and to enable manufacturers to compete successfully in the years to come. According to Kenneth Merk, Executive VP-Sales & Service, "Hermle's well received 5-axis concept has taken a giant leap forward - separating us from the competition. In conjunction with DELCAM International's exceptional software, our machining centers are helping customers with a wide range of aerospace and other demanding applications in specialized alloys. In fact, Hermle's extensive experience in 5-axis machining is proving invaluable to manufacturers who require complex parts in production quantities."
