(1) Vertical CNC lathe vertical CNC lathe referred to as CNC vertical lathe, the lathe spindle is vertical to the horizontal plane, a large diameter circular worktable, used to clamp the workpiece. This kind of machine tool is mainly used for processing large complex parts with large radial size and relatively small axial size.
(2) Horizontal NC lathe horizontal NC lathe is divided into NC horizontal guide horizontal lathe and NC inclined guide horizontal lathe. The inclined guide rail structure can make the lathe more rigid and easy to remove chips.
Classification according to the basic types of machined parts
(1) Chuck type CNC lathe has no tailstock, which is suitable for turning disc (including short shaft) parts. The clamping mode is mostly electric or hydraulic control, and the chuck structure has adjustable claw or non quenched claw (soft claw).
(2) This kind of lathe is equipped with ordinary tailstock or CNC tailstock, which is suitable for turning long parts and disc parts with small diameter.
According to the number of turrets
(1) Single turret CNC lathe is generally equipped with various forms of single turret, such as four position horizontal rotation turret or multi position turret automatic rotation turret.
(2) Double turret CNC lathe this kind of lathe double turret configuration parallel distribution, can also be mutually vertical distribution.
By function
(1) The simple CNC lathe, which is formed after the feed system of ordinary lathe is transformed by stepping motor and single chip microcomputer, has low cost, but the degree of automation and function are relatively poor, and the turning accuracy is not high. It is suitable for the turning of rotary parts with low requirements.
(2) According to the turning requirements, the general CNC lathe is specially designed in structure and equipped with general CNC system. The CNC system has strong function, high degree of automation and machining accuracy, and is suitable for turning general rotary parts. The CNC lathe can control two coordinate axes, namely X axis and Z axis.
(3) On the basis of ordinary CNC lathe, turning center adds c-axis and power head. More advanced CNC lathe has tool magazine, which can control x, Z and C coordinate axes. Linkage control axes 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 be used for radial and axial milling, surface milling, drilling of holes and radial holes whose center line is not in the rotation center of parts.
