Lontra takes advantage of ‘green’ machine tools

There is an unusual parallel between a new, low-pressure air compressor (blower) manufactured by entrepreneurial British firm Lontra and the Japanese-built turn-mill centre from Okuma that machines one of the fundamental components of the Lontra LP2. Both pieces of equipment are engineered to deliver maximum environmental sustainability during operation and both harness Industry 4.0 connectivity to make them even more efficient. Okuma’s UK and Ireland sales agent NCMT describes the multi-tasking turn-milling application.

An Okuma Multus B550 turn-milling centre performs finish-machining operations on the blower rotor, a high-value component critical to LP2 operation. Adrian Pratt, manufacturing engineer at Lontra, says: “We approached NCMT for a turnkey solution. There are not many factories globally that have the machinery or skillset to manufacture a part like this. The Okuma is a very clever, multi-tasking machine that has the size, robustness and technology to machine our large, heavy rotors accurately and repeatably in fewer set-ups. The repeatability aspect is very important as we need to keep all the rotational parts concentric.”

He continues: ” We can machine multiple features in one go on the Multus B550, allowing us to meet the high drawing tolerances by avoiding repeated re-fixturing of the rotor. Without this advanced equipment, we would need 10 operations to complete the rotor component. With the aid of Okuma machinery, we’ve successfully reduced the number of operations by half, further cementing our commitment to lean, smart and sustainable manufacturing practices and continual improvement.”

Greig Underwood, NCMT’s regional sales manager, adds: “What interests me about this installation is the alignment between Lontra and Okuma in their commitment to sustainable manufacturing practices, as well as their shared focus on energy-saving designs for their respective product solutions.”
