Features and benefits

Supports a wide range of processing

It can handle a wide range of machining operations, including not only pin journals, main journals, and their combined machining, but also counterweight side and peripheral machining. High-precision specifications can also be used for pin journal R-grooving, pin journal circumference machining, and mid-finish machining of width determination.

Minimize total cost

Inserts can be used for up to 8 corners. Running costs are reduced. Air consumption is reduced by the use of a chuck shutter. Coolantless processing saves energy.

Highly rigid structure machine

The internal blade cutter, which is more rigid than the external blade cutter, is used for heavy-duty machining. The fixed chuck system eliminates backlash and ensures high workpiece support rigidity. Komatsu NTC's unique swing arm mechanism realizes highly rigid and low-vibration processing.

Outstanding operability and maintainability

Uses the latest automated programming system. The operation panel can be used to check the operating location, fault location, and restoration method. No crane is required* when replacing the cutter due to the use of a compact and lightweight cutter. This reduces the workload on the operator. (*Except GPM240 and GPM320)
