5-axis future

Altec has invested heavily in new multi-axis machine tool technology in recent times. The first 5-axis machine to arrive was a Mazak VCT800/30SR machining centre. A moving gantry style machine with rotational B-axis and large work envelope of 3,000mm x 800mm x 720mm, this machine has proven to be a valuable asset to the business being used to fulfil a number of contracts for both aerospace and defence related components. The extended tool magazine, wireless Renishaw probe measurement, 70 bar coolant to cover gundrilling applications and a centre partition allows different components to be machined simultaneously.

Installed just three months ago is Altec’s latest Mazak Variaxis i-700, featuring the new control system Smooth X. This trunnion style simultaneous 5-axis machining centre has improved surface speed interpolation; brought seamless corner control to limit vibration, and intelligent pocket milling allowing accurate processing of parts with complex profiled surfaces in a single set-up.

The machine’s two pallet changer provides unattended operations and lights out running plus the benefit off-cycle changeover/fixturing set-up. This simple, efficient form of automation allows operators to load, unload and inspect parts on one pallet while the machine works on the other maintaining the highest levels of productivity at all times.

Altec’s venture into 5-axis machining continues with the announcement, following the Farnborough Air Show, that it has placed a repeat order for another 5-axis Mazak VTC800/30SR. The specification for this latest machine is in line with Altec’s other 5-axis systems which manufacture a comprehensive range of components in aluminium and titanium. Due for delivery at the end of September 2016 with installation during October, the machine will be operational and ready for production in November, giving Altec’s production planners welcome relief to the company’s expanding order book.

Altec Engineering group business development director Paul Lackenby says: “The multi-axis capability we have developed at our Durham facility is impressive and ranges in size from large bed machines to multi-pallet systems with in-process probing.

“Our large bed machines incorporate high pressure coolant for high-speed machining and this feature also allows us to bring certain deep hole features in-house, making Altec a very viable and competitive machining partner in the marketplace. We are committed to expanding our capabilities in multi-axis machining as the recent order to Yamazaki Mazak UK demonstrates.”

Originally founded in 1978 Altec Engineering’s Durham facility, now headquarters for the Altec Engineering Group, has over the years built up a reputation for excellence, supplying low to medium volume, medium to high complexity components into sectors such as defence, aerospace, space science, nuclear and renewables and oil and gas.
