CNC lathe is mainly used for turning, boring, drilling, reaming, tapping and other processes of rotating parts. Generally, it can automatically complete the cutting of inner and outer cylindrical, conical, spherical, cylindrical threads, grooves and end surfaces.

Modern NC lathes have the functions of X and Z axis linkage, tool position and tool tip arc radius compensation, and processing fixed cycle.

Structure of CNC Lathe

1. CNC lathe

CNC turning and milling compound processing manufacturer introduces the composition of CNC lathe: CNC system, lathe bed, spindle, feed system, rotary tool holder, operation panel and auxiliary system.

CNC lathes are divided into vertical CNC lathes and horizontal CNC lathes.

Vertical CNC lathe is used for turning disc parts with larger rotary diameter.

Horizontal CNC lathe is used for turning long or small disk parts.

Horizontal CNC lathes can be further divided into economic CNC lathes, general CNC lathes and turning centers according to their functions.

(1) Economic CNC lathe: A simple CNC lathe is formed by reforming the turning feed system of the ordinary lathe with stepping motor and single chip microprocessor. Low cost, poor automation and function, low turning accuracy, suitable for turning parts with low requirements.

Economical numerical control lathe

(2) CNC turning and milling complex processing company analysis, general CNC lathe: according to the requirements of turning processing in the structure of a special design, equipped with a general CNC system and formed a CNC lathe. The NC system has strong functions, high automation and processing accuracy, and is suitable for turning general rotary parts. This NC lathe can control two coordinate axes at the same time, i. e. X axis and Z axis.

General CNC lathe

(3) Turning center: On the basis of general NC lathe, C-axis and power head are added. The higher-level machine tool also has tool library, which can control X, Z and C coordinate axes. The linkage control axes can be (X, Z), (X, C) or (Z, C). Because of the addition of C-axis and milling power head, the processing function of this NC lathe is greatly enhanced. Besides general turning, it can also carry out radial and axial milling, surface milling, drilling of holes whose centerline is not in the center of rotation of parts and radial holes.

Hydraulic chuck and hydraulic tailstock

Hydraulic chuck is an important accessory for clamping workpiece in NC turning. It can be used for general rotary parts; special chuck is needed for parts that are not cylindrical in clamping position; spring chuck is needed for parts directly processed with bar material.

CNC Turning-Milling compound processing manufacturer introduced that for parts with large ratio of axial dimension to radial dimension, the movable tip installed on the hydraulic tailstock should be used to support the tail end of the parts, so as to ensure the correct processing of the parts. The tailstock has common hydraulic tailstock and programmable hydraulic tailstock.
