Marquin buys another Mori Seiki DCG

Marquin Engineering has bought a NH6300 DCG II to add to its previous Mori Seiki DCG (driven at the centre of gravity) purchases.

Marquin Engineering machines castings and forgings for companies in the transportation, construction equipment, overhead electrification, commercial refrigeration, defence and rail industries.

It has supplied parts for NATO peacekeeping vehicles and to London Underground.

Marquin Engineering is ISO9001-2000 approved and has CNC controlled CMM equipment in a temperature-controlled room and on machine probing, to maintain its quality standards.

George Spencer, director of Marquin Engineering, said: 'Our customers are demanding greater flexibility and shorter lead times, so we have to be able to react quickly to their changing requirements.' Marquin Engineering installed its first Mori Seiki NH4000 DCG in 2003.

Within 18 months the company had bought two more.

Spencer added: 'Floor space is at a premium in our factory, so the small footprint of these machines, thanks to their box-in-box construction, was very important to us.

'The NH4000 DCG is very easy to maintain, as all the solenoids can be easily accessed by simply removing the guards.' When Marquin needed a new motor on one of its NH4000 DCG machines, the replacement part was delivered overnight and the repair was completed in half a day.

Marquin bought a Mori Seiki NH6300 DCG in early 2007 for larger castings and is just taking delivery of a NH6300 DCG II.

This second machine has a work envelope 1.1 times wider than the previous model, yet takes up 11 per cent less floor space.

Spencer added: 'The NH6300 DCG II has a smaller footprint but it has longer travel, further increasing the size of parts we can cut.' Marquin has two NH6300 DCG and three NH4000 DCG machines, which, in the event of a problem, allows it to switch parts between machines without delay, ensuring continuity of supply.

Since installing its first Mori Seiki, Marquin has doubled its capacity and the addition of the new NH6300 DCG II will further increase it by 12 per cent.

The trend in the company's business is towards medium - low volume, precision parts.

Hydraulic fixturing and edge locators allow rapid part loading and unloading as well as fast fixture changing, while the power and rigidity of the Mori Seiki machines make it possible to combine heavy cutting for speed with highly accurate parts.
