HMC builder offers fixture design/build
service
Renowned for its simultaneous engineering expertise, Heller Machine Tools is one of few UK machining centre builders able to provide a fixture design and build service using its own engineers.
The UK-based manufacturer of horizontal machining centres, Heller Machine Tools, will be demonstrating its ability to provide production productivity at MACH 2006 With two machines cutting metal on its stand - the compact MC 12 and the powerful MCH 250 - the company aims to represent the range of its machines as well as the extent of its engineering services

Fast HMC to get through automotive volumes
a fast, versatile HMC, developed primarily for higher volumes, typically the automotive industry, features 90m/min fast traverse, acceleration of 12mm/sec2 and and 1.8sec chip-to-chip ATC.
Machining centre machines to close tolerances
A small family-owned business will increase its turnover by 35.2% this year and, on new M-Cs, consistently machines to tolerances which would frighten the majority of engineers.
Heller manufactures machines for a wide variety of customers, from small sub-contractors to large Tier 1 automotive manufacturers and supplies everything from single stand-alone machines to fully-integrated turn-key cells compliant with the most stringent of operating standards.
The company is renowned for its simultaneous engineering expertise and is one of few UK manufacturers to provide a fixture design and build service from its own site using its own engineers.
Geoff Lloyd, managing director of Heller, said: "Our intention at MACH is to show how we can deliver the requirement of companies seeking greater production productivity and therefore profitability and to demonstrate our broad capability.

Narrow footprint twin spindle M-C doubles output
Productivity is doubled and costs almost halved by the new, true twin spindle horizontal machining centres that can operate on two separate fixtures simultaneously.
We seek to provide excellence in all aspects of our business, from the actual machine design and build, through engineering support, fixture manufacture, value stream mapping to post-installation support and service.
All our machines are designed and built specifically to achieve very high productivity rates and furnish exceptional up-times.
More important even than that, our engineering services have been structured to ensure that high performance is realized in the most efficient and cost effective way." Lloyd added: "Our stand at the MACH 2006 exhibition will include pavilions both for fixtures and engineering and for project management, rebuilds and service.
We are demonstrating the MC 12 and the MCH 250 machines to show the breadth of our range, from small and very fast to the larger, more powerful machine for applications where high torque is necessary." The MCH and MCi horizontal machining centres are built at Heller's plant in Redditch, UK.
They have the high build quality which provides the rigidity, robustness and precision needed for efficient and profitable production by giving greater productivity, faster chip to chip times, bigger axes and greater tool capacity with a reduced footprint.
The MCH250s are each equipped with SK 50 or HSK 100 heavy duty spindles, with hydraulic fixtures and the Siemens 840D controller.
The large working envelope is 800mm (X) x 800mm (Y) x 800mm (Z).
Spindle speed is 45-6,000 rev/min (12,500 rev/min is an option).
Pallet size is 630 x 630mm.
The chain magazine has been designed to provide extremely short tool-to-tool times because of its high travel rate.
Tools are accepted in a 100 pocket chain magazine or in a 400 place rack type magazine.
Rapid traverse is 50m/min as standard with 60m/min as an option.
Acceleration is 4m/s2 with 7m/s2 as an option.
Chip to chip time is 3.8s.
Control is by Siemens Sinumerik 840D or Fanuc 160i.
The compact MC 12 has a small footprint yet provides travel in X of 560mm, 560mm in Y and 510mm in Z.
Pallet size is 400mm x 400mm.
Rapid traverse is 50m/min, axis acceleration 7m/s2, and shorter tool-to-tool times are achieved by the mechanically actuated tool changer, and chip time can be as little as 4.6s.
Spindle speed is 45-12,000 rev/min and spindle torque 83Nm.
Positioning tolerance is 7 micron.
Control is by the powerful Siemens 840D or the Fanuc 18i systems. Request a free brochure from Heller Machine Tools ...
