Description

CNC numerical control machining center is originally pressed pressure head base for lathe

Technical Field

The invention relates to the technical field of CNC (computerized numerical control) machining centers, in particular to a main pressure head base for a machine tool of a CNC machining center.

Background

CNC machining is a mechanical machining technology, and the main work is to program a machining program, namely, the original manual operation is changed into computer programming. Of course, manual machining experience is required. The feeding processing route of the numerical control lathe refers to a route through which the turning tool starts to move from the tool setting point until the turning tool returns to the point and the processing program is finished, and the route comprises a cutting processing route and a non-cutting idle stroke route such as cutting in and cutting out of the tool. The feed path for finishing is essentially sequential along the contour of the part, and therefore the work focus of determining the feed path is determining the feed path for roughing and idle strokes. In the numerical control lathe processing, the processing route is generally determined according to the following principles. The precision and the surface roughness of the processed workpiece can be ensured. And the processing route is shortest, the idle travel time is shortened, and the processing efficiency is improved. And thirdly, the workload of numerical calculation is simplified as much as possible, and the processing procedure is simplified. For some programs that are used repeatedly, a subroutine should be used. CNC machining has the following advantages: the number of the tools is greatly reduced, and the complex tools are not needed for processing parts with complex shapes. If the shape and the size of the part are required to be changed, only the part machining program needs to be modified, and the method is suitable for new product development and modification. Secondly, the processing quality is stable, the processing precision is high, the repetition precision is high, and the processing requirements of the aircraft are met. Production efficiency is higher under the condition of multi-variety and small-batch production, the time of production preparation, machine tool adjustment and process inspection can be reduced, and the cutting time is reduced due to the use of the optimal cutting amount. Fourthly, the complex molded surface which is difficult to process by the conventional method can be processed, and even some processing parts which can not be observed can be processed. The disadvantage of numerical control machining is that the machine tool equipment is expensive and requires a high level of maintenance personnel.

The numerical control machining is machining using a numerical control machining tool. CNC machining machines are programmed in a nc machining language, typically G-code. The numerical control machining G code language tells the machining tool of the numerical control machine tool which Cartesian position coordinate is adopted, and controls the feeding speed and the main shaft rotating speed of the tool, and functions of a tool converter, a coolant and the like. Numerical control machining has great advantages over manual machining, and parts produced by numerical control machining are very accurate and have repeatability; numerical control machining can produce parts with complex shapes which cannot be finished by manual machining. The numerical control machining technology is widely popularized, most machining workshops have numerical control machining capacity, and the most common numerical control machining modes in a typical machining workshop comprise numerical control milling, numerical control turning and numerical control EDM wire cutting (wire cut electrical discharge machining). The tool for carrying out numerical control milling is called a numerical control milling machine or a numerical control machining center. The lathe for performing numerical control turning is called a numerical control turning center. The G-code of the numerical control machining can be programmed manually, but usually, a machining shop automatically reads a CAD (computer aided design) file by CAM (computer aided manufacturing) software and generates a G-code program to control the numerical control machine tool. The existing pressure head base for the CNC machining center machine tool is poor in fixing effect, and cannot clamp and fix parts according to different sizes, so that the clamping and fixing efficiency of the parts is greatly reduced.
