Sawing way of copper pipe

Sawing is one of the most versatile and widely adapted methods for cutting tubing. Each sawing application is unique, but, generally, sawing is suitable for low-volume production.

A double-head cold saw usually cuts one tube at a time. In all sawing applications, the number of teeth required on the blade is based on the number of teeth that contact the tube on the maximum arc of the cut. Having too few teeth contacting the tube limits production rates and causes vibration. Having too many teeth contacting the tube causes chips to become clogged in the teeth, perhaps causing the teeth or the blade to break.

In principle, cold sawing is the same as turning and milling. Metal is removed by shearing with positive rakes. The basic blade design for cold sawing is a common tooth shape. The cutting zone is cooled to minimize saw tooth softening by lubricating it with soluble oil emulsions or synthetic oil directly in the cutting zone.
