The CNC lathe is composed of CNC device, bed, spindle box, tool rest, feed system, tailstock, hydraulic system, cooling system, lubrication system, chip conveyor and other parts. CNC lathes are divided into two types: vertical CNC lathes and horizontal CNC lathes.
1. Vertical CNC lathes are used for turning disc parts with larger diameters.
2. Horizontal CNC lathes are used for turning of long axial dimensions or small disc parts.
Horizontal CNC lathes can be further divided into economical CNC lathes, ordinary CNC lathes and turning centers according to their functions.
1. Economical CNC lathe
A simple CNC lathe is formed by transforming the turning feed system of an ordinary lathe by using a stepping motor and a single-chip microcomputer. The cost is low, the degree of automation and functions are relatively poor, and the turning accuracy is not high, and it is suitable for turning of rotary parts with low requirements.
2. Ordinary CNC lathe
According to the requirements of turning processing, it is specially designed in structure and equipped with a CNC lathe formed by a general CNC system from cnc spare parts suppliers. The CNC system has strong functions, high degree of automation and high machining accuracy, and is suitable for turning of general rotary parts. This CNC lathe can control two coordinate axes at the same time, namely the x-axis and the z-axis.
3. Turning machining center
On the basis of ordinary CNC lathes, C axis and power head are added. More advanced machine tools also have tool magazines that can control three coordinate axes of X, Z and C. 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 processing function of this cnc lathing oem is greatly enhanced. In addition to general turning, it can also perform radial and axial milling, surface milling, holes whose centerline is not at the center of rotation of the part, and drilling of radial holes.
Hydraulic chuck and hydraulic tailstock:
Hydraulic chuck is an important accessory for clamping workpieces during CNC turning. For general rotary parts, ordinary hydraulic chucks can be used; for parts whose clamped parts are not cylindrical, special chucks are required; steel When machining parts directly from material such as the custom aluminium parts, a spring chuck is required.
For parts with a large ratio of axial size to radial size, it is necessary to use a live center mounted on the hydraulic tailstock to support the tail end of the part, so as to ensure the correct processing of the part. There are common hydraulic tailstocks and programmable hydraulic tailstocks.
