In-process QC made on CNC sliding head
lathes
Subcontractor has developed a measuring system for real-time, in-process quality control of components on CNC mill-turn sliding head automatic lathes.
Turned parts subcontractor, Davromatic Precision, claimed a 'world first' by developing a measuring system for real-time, in-process quality control of components as they are turned and milled on its Star multi-axis CNC sliding-headstock lathes Said Davromatic's managing director, Martin Ollis, "Being able to carry out 100% inspection of critical dimensions, without handling the parts again, has given us the ability to offer customers a level of service and price that our competition is unable to match"

Davromatic said that its development has enabled it to invest heavily in new machines.
In a report sent by Star Micronics GB to manufacturingtalk.com, Davromatic said it had installed its latest Star lathe, model SB-16D, in April 2007.
The three machines installed before that, all Star SR-20RIIs with extensive driven tool and rear-working capabilities, were purchased within an 18-month period.
Davromatic specialises in work for the defence industry and also serves the automotive, aerospace and medical sectors.
Davromatic said it often wins contracts to supply high-precision components produced from tough or difficult-to-machine materials.
This type of work tends to be problematic for sliding-head lathes, as they are often of relatively lightweight construction so arduous cutting cycles can cause loss of accuracy.
Ollis regards Star machines as the most robust on the market and best suited to machining tool steels, stainless steels and nickel alloys.
The first Star sliding-head lathe, an SR-20R, was installed at Davromatic in 2004.
Shortly after, Ollis won a contract from a well-known car manufacturer for the supply of high tensile steel bolts in EN16T.
Ollis discovered at the time that the installed weight of Star lathes is typically 25% more than those offered by other vendors.
He concluded that Star machines would be the most suitable for taking heavy cuts in tough metals, using the main and counter spindle.
In practice.
When , for example, comparative cycle time trials showed the SR-20R to be 10% faster than competitive machines when producing the steel bolts.
