NC rotary tables boast high speed and accuracy

Building on the proven capabilities of Kitagawa's MR series units, the MR201 achieves a clamping torque of 820Nm from a standard 0.5MPa compressed air supply,­ which is more than twice the performance of the MR200 model. It also provides a maximum indexing speed of 41.6rpm - which is 25 per cent faster than the MR200 -­ and incorporates the compact design and excellent indexing accuracy of other MR series units, making it suitable for a wide variety of high-speed, rotary axis machining applications. The new unit also features a 202mm diameter faceplate and a compact motor casing for maximum machining flexibility.

Kitagawa's TW2180 is an advanced twin-spindle table, tilting-axis rotary unit capable of supporting simultaneous machining operations on two workpieces in a single set-up. It measures just 999mm wide and features two 180mm diameter tables with maximum indexing speeds of 33.3rpm. In addition, the TW2180 provides a tilt range of +110 degrees of vertical and a tilt axis speed of up to 16.6rpm.

With clamping torques of 400Nm in the rotary axis and up to 800Nm in the tilting axis, the TW2180 is also suitable for aggressive, high-speed machining operations.

The unit can also be fitted with an optional rotary joint to permit pneumatic or hydraulic fixtures to be used without external pipework, thereby improving tool access and increasing the available machining area.
