Mill-turn centre machines six faces
A mill-turn centre differs considerably from similar products from some lathe suppliers in that it is a piece of prismatic metalcutting equipment, which has been given extensive turning capabilities.
The Stama mill-turn centre, MC526/MT differs considerably from similarly named products from lathe suppliers in that it is fundamentally a piece of prismatic metalcutting equipment which has been given extensive turning capabilities All six faces of a component may be machined by combining 5-axis working with pick-off and reverse end machining similar to that offered by conventional turn-mill equipment

High performance machining centre cuts 'dry'
The latest new addition to the Stama range is the MC 326, a compact machine available in single- and twin-spindle formats and offers high performance machining in dry cutting conditions.
Centre machines workpieces six sides in one
Stama has combined a 5-axis machining centre with a trunnion-mounted turning unit - horizontal and vertical attitudes - and which also functions as two-axis positioner for milling.
The demonstration piece illustrated this capability.
It was the front end of an indexable insert drill, completely machined in one set-up from tool steel in a 6.15 min cycle using 17 tools.
The machine's milling unit is driven by a 37kW / 12,000 rev/min spindle while turning unit power is 42kW/5,000 rev/min.
Tools are exchanged from a 42-station magazine, only one being allowed in the working area at any given time.
Workpiece clamping is in standard collets, eliminating the need for expensive fixtures.
Under power also for the first time in this country was high speed machining centre, MC326/S.
Two parts were produced, with and without coolant, to illustrate the capabilities of the machine.
One was a steel demo involving a seven minute milling and drilling routine.
The other was an actual component - a clock housing produced from aluminium, fixtured two at a time and machined complete in five minutes.
Available in single- and twin-spindle formats, the machine offers high performance in dry machining applications in keeping with modern environmental concerns.
Working range of the single-spindle version, as shown, is 520mm in X by 300mm in Y by 360mm in Z.
The 37kW/20,000 rev/min spindle combines with 60m/min rapid traverse in all axes to provide top rates of productivity.
