CNC lathe machining is a high-tech machining method for precision hardware parts. The high-speed machining center machine can process various types of materials, including 316, 304 stainless steel, carbon steel, alloy steel, aluminum alloy, zinc alloy, titanium alloy, copper, iron, plastic, acrylic, POM, UHWM and other raw materials. Square, round combination of complex structure parts.
The technical level of CNC machine tools and the percentage of the output and total ownership of metal cutting machine tools are one of the important indicators to measure the development of a country’s national economy and the overall level of industrial manufacturing. CNC lathe is one of the main varieties of CNC machine tools. It occupies a very important position in CNC machine tools. It has been widely valued by countries in the world for decades and has been rapidly developed.
The CNC lathe is composed of CNC device, bed, spindle box, tool post feed system, tailstock, hydraulic system, cooling system, lubrication system, chip conveyor and other parts.
CNC lathes are divided into vertical CNC lathes and horizontal CNC lathes.
Vertical CNC lathes are used for turning disc parts with large turning diameter.
Horizontal CNC lathes are used for turning long axial dimensions or small disc parts.
Horizontal CNC lathes can be further divided into economical CNC lathes, ordinary CNC lathes and turning machining centers according to their functions.
- (1) Economical numerical control lathe: a simple numerical control lathe formed by using a stepping motor and a single-chip computer to transform the turning feed system of an ordinary lathe. The cost is low, the degree of automation and function are relatively poor, and the turning machining accuracy is not high. It is suitable for turning machining of less demanding rotary parts.
- (2) Turning machining center: on the basis of ordinary CNC lathes, the C axis and power head are added. The more advanced machine tools also have a tool magazine, which can control the X, Z and C coordinate axes. The linkage control axis can be (X, Z), (X, C) or (Z, C). Due to the addition of C-axis and milling power head, the machining function of this CNC lathe is greatly enhanced. In addition to general turning, it can also perform radial and axial milling, curved surface milling, and holes and diameters whose center line is not at the center of rotation of the part Drilling of holes, etc.
CNC lathes, also known as CNC lathes, that is, computer numerically controlled lathes, are currently the most widely used and widely covered CNC machine tools in China, accounting for about 25% of the total number of CNC machine tools. CNC machine tool is a mechatronics product integrating mechanical, electrical, hydraulic, pneumatic, microelectronics and information technologies. It is a working machine with the advantages of high precision, high efficiency, high automation and high flexibility in mechanical manufacturing equipment.
