As we all know, CNC machining center is suitable for machining complex, multi process, high requirements, need a variety of types of ordinary machine tools and a variety of tool fixtures, and need to clamp and adjust many times before processing parts. The machining objects are mainly box parts, complex curved surfaces, special-shaped parts, clad plate parts and special machining. What are CNC parts processing? Shenzhen Noble Intelligent Manufacturing Technology Co., Ltd. will explain it to you specifically!
Robot parts processing
1、 Box parts:
Box parts generally refer to parts with multiple hole systems, cavities inside, and a certain proportion of length, width and height. Such parts are mostly used in machine tools, automobile, aircraft manufacturing and other industries. Box shaped parts generally require multi station drilling and plane processing, with high toleraCNCe requirements, especially strict form and position toleraCNCe requirements. They usually go through milling, drilling, expanding, boring, reaming, spot facing, tapping and other processes, requiring more tools. For the machining center for machining box parts, when there are many machining stations and the worktable needs to rotate for many times to complete the parts, the horizontal boring and milling machining center is generally selected.
2、 Complex surface parts:
Complex surfaces play an important role in mechanical manufacturing, especially in aerospace industry. It is difficult or even impossible to complete complex surfaces using ordinary machining methods. In China, the traditional method is to use precision casting, which can be imagined to be low in accuracy. Complex surface parts, such as various impellers, wind deflectors, spheres, various surface forming molds, propellers, underwater vehicle propellers, and other free surfaces.
3、 Special parts and accessories
Special shaped parts are parts with irregular shape, and most of them require multi station hybrid processing of points, lines and surfaces. The rigidity of special-shaped parts is generally poor, the clamping deformation is difficult to control, the machining accuracy is difficult to ensure, and even some parts of some parts are difficult to complete with ordinary machine tools. When machining with a machining center, reasonable process measures shall be taken, iCNCluding one-time or secondary clamping, and the characteristics of multi station point, line and surface mixed processing of the machining center shall be used to complete multiple processes or all processes.
4、 Disc, sleeve and plate parts:
Vertical machining centers shall be selected for disk parts with keyways, or radial holes, or distributed hole systems, curved disk sleeves, or shaft parts, such as flanged shaft sleeves, keyways, or square head shaft parts, as well as multi hole machining plates, such as disk parts with distributed holes and curved surfaces on various motor end faces, and horizontal machining centers with radial holes.
5、 Trial production parts of new products:
CNC machining center has wide adaptability and high flexibility. When the processing object is changed, the processing can be realized by compiling and inputting a new program.
CNC processing of medical parts
CNC machining is a very convenient and effective manufacturing technology. It uses computer digital control (CNC) technology to control the machines and tools for processing various materials and articles. What problems should we pay attention to when processing spare parts?
1、 CNC tool selection for parts CNC machining:
The CNC machining quality of product parts depends to a great extent on the quality control of CNC tools. According to acoustic material monitoring, milling time control, stop inspection during milling, surface layer analysis of product parts and other methods, distinguish all normal damage conditions and abnormal damage conditions of CNC tools in the whole process of automatic milling. The milling cutter shall be solved immediately according to the production and processing regulations to prevent production and processing quality problems caused by improper handling of CNC cutters.
2、 CNC parts processing flow:
When monitoring rough machining, the main consideration is to quickly remove the excess capacity of the product surface layer. During automatic production processing, CNC tools automatically perform milling production processing according to the preset feed rate and the predetermined milling movement path. At this time, the actual operators should pay attention to the change of milling load in the whole process of automatic production and processing of spare parts, and adjust the feed rate according to the bearing capacity of the CNC cutter to make full use of the relatively high efficieCNCy of the CNC machine tool.
(1) After the CNC machining center is powered on, check whether all switch buttons and indicator lights are normal. If there is any abnormality, shut down the machine immediately and report it to the maintenaCNCe personnel.
(2) Before formal processing, return the coordinates of the machining center to zero, and let the machine idle for more than 15 seconds before formal operation.
(3) In order to simplify positioning and installation, CNC machining centers have relative processing origins on no positioning surfaces and precise coordinate dimensions.
(4) During installation, ensure that the stroke of the workpiece is within the stroke range of the spindle.
(5) When installing the workpiece, it is necessary to ensure that the workpiece is installed firmly, but it is also important not to tighten it too tightly, which may lead to loss of positioning accuracy.
3、 CNC parts milling sound monitoring:
Generally, at the beginning of automatic milling production, the sound of CNC tool milling product parts is relatively stable, continuous and fast, and the motion of CNC machine tool is relatively stable. In the whole process of production and processing, the production and processing are unstable due to the existeCNCe of hard spots in product parts, the destruction of CNC tools, the clamping of CNC tools and other reasons. Its expression forms are the transformation of milling sound, the mutual impact sound between CNC tools and product parts, and the vibration of CNC machine tools. During this period, the feed rate and milling standard shall be adjusted immediately. When the adjustment effect is not obvious, the CNC machine tool shall be interrupted and the condition of the CNC cutter and product parts shall be checked.
