CNC turning centres halve machining times

RandG Precision Engineering has invested in Mori Seiki CNC machinery and realised savings in inter-operation handling, reduction of tool set-up times and higher metal removal rates.

RandG services clients in oil and gas, defence, medical and telecommunications industries.

It has been using CNC machinery since 1990 and has a plan of continuous investment - GBP600,000 in 2008 and a further GBP275,000 in 2009 - to maintain and improve its service.

As part of this programme, it purchased a Mori Seiki NL2500 turning centre with driven tool turret and Y axis in 2008 and a Mori Seiki NZ2000 twin-spindle twin-turret turning centre with a 65mm bar feed in January 2009.

Joe Giammasi, managing director of RandG, said: 'The live tools enable us to complete parts in one operation.

'Savings in handling between operations, elimination of associated tool set-up times and the much higher material-removal rates, achievable on the NL2500 and the NZ2000, have cut machining times in half.' RandG Precision's close relationship with its customers has benefited from the reduced cycle times and the increased flexibility provided by the Mori Seiki machines, enabling it to offer ex-stock delivery on many parts.

The rigidity of the Mori Seiki machines has also increased tool life.

Giammasi added: 'The NL2500 is reducing our tool usage by 25 per cent on average, while on some jobs we are enjoying as much as 50 per cent improvement in tool life.

'We anticipate that tool usage will be even lower on the NZ2000.' The reliability of Mori Seiki's machines and the service it provides were important factors in RandG Precision's investment decision.
