I. Introduction 

EOSP type combined skiving & roller burnishing tools provide a cost-efficient and environmentally sensitive method for machining the inner surfaces of cylinders in just one step.

EOSP type combined skiving & roller burnishing tools are designed to finish seamless or welded cold drawn precision tubes after counter boring (including welded and drawn DOM tubes, seamless cold drawn tubes, or hot rolled steel tubes). The skiving head cuts the tube’s inner surface to the exact size and form required, while the roller head burnishes it. This simultaneous skiving and burnishing results in a short overall process time.

Through cold working, this forming process achieves a large surface contact area, low surface roughness and increased hardness. Thus, in contrast to honed tubes, the burnished cylinder surface has better sliding and wear properties.

EOSP type combined skiving & roller burnishing tools can be used with specially designed cylinder processing machines or trepanning machines with BTA boring systems. In addition, special versions are available for use with alternative thread connections, including Sandvik or Sierra.

Single Pass

Skiving and roller burnishing is performed in the forward direction, the workpiece is quickly returned, and processing is completed.
With the 1-way method, because skiving and roller burnishing take place under the same process and quick return is possible, the processing time can be shortened. The processing conditions must be set to either the skiving or roller burnishing conditions.

Double Pass

Skiving is performed in the forward direction, roller burnishing is performed in the return direction, and processing is completed.
With the 2-way method, because the skiving and roller burnishing processes are separate, processing can be performed using the optimal processing conditions for each. However, quick return is not possible.
