Everybody's watching.CNC latheThe difference between CNC lathe and turning centre, however, many people are not able to find the detailed records. This article will take the opportunity to bring you from different aspects of a more reasonable understanding of the difference between CNC lathes and turning centres, expect more people to get the information they want from this article, see more details in this article.
There are two main types of CNC lathes, horizontal and vertical. Horizontal lathes, there are two kinds of horizontal guideways and inclined guideways. Higher grade CNC horizontal lathe ah, usually but the use of inclined guideway. According to the number of tool holders to classify, CNC lathe can be divided into single tool holder CNC lathe and double tool holder CNC car, single tool holder CNC lathe is two coordinates control, and not, double tool holder CNC car is 4 coordinates control. Most of the double tool holder horizontal lathe adopts inclined guideway.
CNC lathes, like ordinary lathes, are used toMachined partsRotating surface, generally can automatically complete the processing of external cylindrical surface, can automatically complete the processing of conical surface, can automatically complete the processing of spherical surface, can automatically complete the processing of threads, but also can process some complex rotary surface, like hyperbolic surface, etc., the body and the ordinary lathe workpiece mounting is basically the same, in order to improve the machining efficiency, most of the CNC lathe using hydraulic chuck, using pneumatic chuck, using electric chuck.
The appearance of CNC lathe is similar to ordinary lathe, its components are bed, spindle box, and tool holder, as well as feeding system, pressure system, cooling and lubrication system. CNC lathe feeding system and ordinary lathe there are qualitatively different, the traditional ordinary lathe has a feed box, with the exchange of gear racks, but the CNC lathe is the use of servo motors, through the ball screw to drive the sliding plate and the tool holder to achieve the feeding movement, so the structure of the feeding system has been greatly simplified.
There are many varieties of CNC lathes with different specifications, which can be classified as follows.
Classification by lathe spindle position
(1) Vertical CNC lathe, referred to as CNC vertical lathe, its lathe spindle is perpendicular to the horizontal plane, there is a large diameter circular table for clamping the workpiece, there is also a flexible manufacturing system called fms, this type of machine tool is mainly used for machining large and complex parts, which have large radial dimensions and relatively small axial dimensions.
(2) Horizontal CNC lathe, which is also divided into CNC horizontal guideway horizontal lathe and CNC tilting guideway horizontal lathe, which has a tilting guideway structure, this structure allows the lathe to have greater rigidity, and makes it easy to remove the chips.
Classification by basic types of machined parts
(1) chuck type CNC lathe, this type of lathe does not exist tailstock, suitable for turning discs contain short shaft parts, most of the clamping method is electric or hydraulic control, most of the chuck structure with adjustable jaws or not quenched jaws that is, soft jaws.
(2) top type CNC lathe, this kind of lathe, some with ordinary tailstock, some with CNC tailstock, it is suitable for turning the kind of parts with considerable length, as well as the kind of diameter is not particularly large disc parts.
Classified by the number of tool holders
(1) CNC lathe in a single tool holder, generally have a variety of forms of configuration, such as four-station horizontal indexing tool holder, or multi-station turret type automatic indexing tool holder.
(2) This kind of lathe, that is, double tool holder CNC lathe, double tool holder that configuration can be presented parallel distribution of the situation, of course, for its setup, there is the possibility of each other to take the vertical distribution of the situation.
By Function
(1) Let's first understand how the economical CNC lathe came about. It is through the stepping motor and microcontroller, the ordinary lathe feed system after the implementation of transformation, only to form a simple type of CNC lathe. What are the characteristics of this kind of lathe? It has a relatively low cost. However, itsdegree of automationand functionality, are poor, and the accuracy of the turning process is quite limited. Then which kind of machining is it suitable for? The answer is the turning processing of rotary parts with low requirements.
(2) Ordinary CNC lathe is the kind of CNC lathe based on the requirements of turning processing, in the structure of the special design, and then equipped with a common CNC system formed by the CNC lathe, its CNC system is powerful, the degree of automation is high, the machining accuracy is also relatively high, suitable for general rotary parts turning processing, this CNC lathe can control two axes at the same time, that is, the X-axis and the Z-axis.
(3) Turning machining centre is based on ordinary CNC lathe, with the addition of C-axis and power head, more advanced features of the CNC lathe is equipped with a tool magazine, able to control the three axes of X, Z and C. There are various combinations of the linkage control axes, namely (X, Z), (X, C), or (Z, C).$he machining function of the CNC lathe has been significantly enhanced due to the addition of the C-axis and milling power head, which can carry out general turning operations as well as radial and axial milling, surface milling, drilling of holes and radial holes whose centre line is not in the centre of rotation of the part.$he turning centre is based on ordinary CNC lathe with the addition of C-axis and power head. In addition to general turning operations, it can perform radial and axial milling, surface milling, and drilling of holes whose centre line is not in the rotary centre of the part, as well as radial holes$.
Other classification methods
According to the CNC system of different control forms and other aspects of the indicators, CNC lathe can be divided into many categories, such as linear control of CNC lathes, CNC lathes with two spindle control functions, etc.; based on special or specialised process performance to see, can be divided into threaded CNC lathes, piston CNC lathes, crankshaft CNC lathes, and many other types of CNC lathes.
