Machining centre machines multi-surfaces

Latest high-speed, multi-surface machining concept demonstrates the advantages of 'one hit' machining and across a wide range of industry sectors, including toolmaking, aerospace and automotive.

Yamazaki Mazak unveils its latest high-speed, multi-surface machining concept - the Mazak Angulax 900 - at EMO 2005, where it demonstrated the advantages of 'Done-in-One' machining and highlighting the productivity benefits of this approach for users across a wide range of industry sectors, including toolmaking, aerospace and automotive.

Among these productivity benefits is the ability to continuously machine multiple surfaces, the result of positioning the 30kW, 18 000 rev/min spindle (A-axis) anywhere within its 180-degree angle of movement.

This means that virtually any surface within the machine's 940 mm by 700 mm working envelope can be machined and complex components completed in a single set-up.

Positional accuracy is maintained by using the latest in backlash-free roller gear cams on the A-axis, with precision, temperature-controlled ballscrews on the remaining axes delivering high levels of accuracy and machining feedrates up to 50m/min.

Control is by the easy-to-use Mazatrol 640M CNC unit, which benefits from a conversational programming format that includes numerous enhancements for multi-surface machining.

These include automatic program origin co-ordinate calculation, which determines other machined face origins from a workpiece reference point by specifying the shift amount from that reference point.

Toolchanging is via a high-speed cam-driven mechanism linked to a 30-position tool magazine.

Tools up to 350mm long and 80mm diameter (up to 160mm diameter if adjacent pockets are empty) can be stored, sufficient to meet the majority of machining applications.

Beyond these features, Mazak's experience in producing machines that facilitate productivity improvements is highlighted in the design of the sheetmetal enclosures of the Angulax 900.

When a component requires loading or unloading, the machining area is accessed easily by overhead crane as the doors and top cover retract completely.

This gives unparalleled access to the working area.
