CNC turning centre scored on speed,
accuracy
When an oil and gas sector subcontractor decided to invest in additional turning capability it sought a CNC turning centre that was powerful and fast, accurate, versatile and reliable.
Lanarkshire, UK-based precision subcontract specialist George Taylor (Engineering) has recently invested in a Doosan Puma 280 turning centre supplied by Mills Manufacturing Technology, Leamington The Puma 280 is the sixth CNC machine tool purchased by George Taylor from Mills in the last five years - and, was the first Puma 280 machine to be installed anywhere in the UK

Machining times cut by three-quarters
It used to take Watford-based Parker Hannifin 30 minutes to machine both ends of complex cylinder rods. The same job is now done in seven minutes in a Nakamura Tome TW-20, twin-turret lathe.
Two opposing twin-turret lathes are in one
One of the most capable mill-turning machines ever built, has four turrets, two spindles and offers a total of 13 computer controlled axes.
Said works director Ian Beveridge: "The oil and gas sector is competitive and global.
In order to survive and grow in it precision subcontract companies need to be 'on top of their game' - every day.
All of our efforts and resources are focused on reducing lead times; ensuring part quality (accuracy, surface finish, etc) and making us cost competitive." Beveridge added: "Access to reliable, high-performance machine tools helps improve our productivity and performance as well as increasing our production capacity and manufacturing flexibility." The company's latest Puma 280 investment is a case in point.

HMCs minimise non-cutting time and are accurate
Exceptional value is claimed for the Daewoo ACE HP Series of horizontal machining centres from Mills Manufacturing Technology.
Continued Beveridge: "We manufacture components from a range of materials - many of which are hard and difficult to machine - Inconel, Monel, and duplex steels, etc." He said that these these components are complex and used in sub-sea applications.
They have a high-precision requirement with +/-20 micron accuracy and a surface finish of 16 micron Ra is typical.
The components vary in weight and size and are manufactured in low volumes.
Beveridge explained: "When we decided to invest in additional turning capability we knew exactly what we were looking for - a machine that was powerful and fast, accurate and versatile and, of course reliable.
The Puma 280 'ticked all the right boxes' for us then, and, some eight months after its installation, is still 'ticking' them." The Puma 280 is a high performance turning centre capable of carrying out a variety of machining tasks.
It is ideal for heavy-duty, interrupted cutting operations.
The machine has a 76mm bar working diameter and a 10in chuck.
Maximum turning diameter and maximum turning length are 420mm and 658mm respectively.
The spindle combines high power (22kW) and speed (3500 rev/min) to optimise metal removal rates, even when working on the most difficult of materials.
For increased flexibility and productivity the Puma 280 is equipped with a programmable tailstock (for machining longer components) and a servo-driven 10 station, heavy-duty turret with non-stop, bi-directional capability and 0.15s indexing time.
High-performance and high-torque servo motors drive each axis to provide rapid traverse rates of 20m/min (X-axis) and 24m/min (Z-axis).
The motors have ball screw connection, no intermediate gears and deliver responsive motion with virtually no backlash - providing guaranteed, long life accuracy.
