一、加工原理 我厂的封口车刀是在学习全国小口径铜管封平口车刀经验上不断加以改进而来的,并获得了新的发展和成效。能封直径40毫米以下各种形状管件。 这种刀具加工时无切削,主要依靠主轴旋转时工件和刀具的磨擦,工件摩擦处的温度达700～800℃,在刀具的挤压下,按着刀具的形状 First, the principle of processing I plant sealing lathe is learning from the experience of the country’s small-caliber copper pipe sealing flat mouth unceasingly to be improved, and obtained new development and effectiveness. Capable of sealing 40mm diameter pipe fittings of various shapes. This type of cutting tool without cutting, mainly rely on the spindle rotation of the workpiece and the tool friction, workpiece friction temperature of 700 ~ 800 ℃, squeezed in the tool, according to the shape of the tool
