OKK CNC Machines Corporation
OKK celebrated its 100th anniversary in October 2015. Our first business was manufacturing equipment such as pumps in Osaka City in 1915. In 1934 we started manufacturing machine tools which is now our core business. Having kept"Customer First"as our top priority, we have created and developed high performance, high stability machine tools supporting a wide range of industries by using OKK's proprietary technological capability and predicting customer needs in advance.

OKK has their own specialist functions:
- Box way models are available with enhanced rigidity to absorb cutting vibrations, increasing surface finish and extending tool life.
- In a 5 axis machining center, the geometric errors (rotational axes inclination and displacement) greatly influence accuracy. This function uses a touch sensor to automatically measure and correct for these geometric errors enabling high-accuracy 5 axis indexing and the high quality simultaneous 5 axis machining.
- 3 stepped gear provides exceptional torque. On the HM1600 a 45kW spindle motor is available to maximize material removal rates.
- Soft AC automatically monitors cutting load to protect the machine and expand the service life of tools. Furthermore it will reduce cycle times by applying optimized feed rate override control.
- Tool Center Point Control simplifies 5 axis machining by controlling tool movement at the tool center, even if the tool axis direction changes. Tool tip speed is maintained and a high quality surface is achieved.
