Hard Turning of Small Parts

August 5, 2009

Miyano Machinery has introduced the new GN-3200 turning center. With a 0.1-µm (4 millionths) input tolerance, the machine is ideal for hard turning of small components that are traditionally finished on a grinding machine, according to the company.

Able to achieve tolerances historically associated with grinding operations, the machines are primarily intended for second-operation finishing work and hard turning of heat-treated components. The GN-3200 has a maximum turning diameter of 1.77 in. and maximum turning length of 1.97 in.

The single slide structure of the X-axis turret and the Z-axis spindle achieves almost zero lost motion by improving follow-up accuracy. The X-axis and Z-axis slideways are also hand-scraped.

Designed for out-of-the-box automation, all GN series machines feature a standard, high-speed gantry loader with a maximum service time of 3.5 sec.
