Description

Flat lathe body for lathe with sweeps clearance function

Technical Field

The invention relates to the field of mechanical equipment, in particular to a flat lathe body with a scrap cleaning function for a machine tool.

Background

A numerically controlled lathe, also called a machine tool, is a high-precision, high-efficiency automatic machine manufacturing apparatus, and is generally classified into a metal cutting machine, a metal forging machine, and the like. After the programmer compiles the program, the program is input into a control system of the numerical control lathe to command the machine tool to work, and workers only need to simply assist the work after the work.

In modern machine manufacturing, there are many methods for machining machine parts, including cutting and forging, as well as other machining methods such as casting, welding, stamping, and extrusion. At present, parts with high precision requirements and fine surface roughness requirements generally need to be finally machined on a machine tool by a cutting method, and a large amount of scrap iron is usually generated in the process.
