The selection of rail vertical machining center should be suitable for the product
- When selecting the type, it should be considered to adapt to the product
Each CNC machine tool rail track machining center 850 has limited performance and processing scope. Only in a certain processing condition can the best processing efficiency be achieved for the corresponding machining objects. When selecting the CNC machine tools, the computer gong must consider the advanced nature of CNC machine tools and the adaptability to product categories (product modification), and avoid numerical control as much as possible. It is uneconomical for large machine tools to process small parts and high precision machine tools to process ordinary precision parts, which should be avoided as far as possible.
In terms of specifications, specifications usually refer to the stroke range of 850 coordinate axis and the power of main motor of CNC machine tool rail vertical machining center. When determining specifications, the size distribution of workpiece should be comprehensively considered. Generally, the size of workpiece should be 100-200 mm larger than that of workpiece, There is a big gap between the size of the worktable and the stroke of the coordinate axis of CNC machine tools made by different manufacturers, which can be used as a reference in the selection.
Considering from the type of CNC machine tool, according to the different processing elements of the workpiece, the form of CNC machine tool is also different. For example, the box parts need to be processed around the hole system. At this time, the line rail vertical machining center 850 is not suitable. The horizontal machining center should be considered, and the rotary table should be configured, and the size of the table should adapt to the installation requirements of the workpiece In the machining of cavity parts, the elongation and deformation of the vertical axis of CNC machine tool after heating should be considered in the long-time machining of large parts. Under possible conditions, it is most suitable to select the full closed-loop control mode or the CNC machine tool with full closed-loop control only in the vertical axis.
The performance and processing range of each kind of CNC machine tool is limited. Only under certain processing conditions, the corresponding processing object can achieve the best benefit. When choosing CNC machine tools, on the one hand, we should consider the advanced nature of CNC machine tools and the adaptability to product categories (product modification). On the other hand, we should avoid the waste of large size and high accuracy of CNC machine tools. It is not economical for large machine tools to process small parts and high-precision machine tools for processing ordinary parts. Professional mold manufacturing enterprises should give priority to the selection of CNC milling machines with working bench to meet the requirements. The automatic tool change function has little impact on the processing process, while the automatic tool change function (tool magazine) of large CNC machine tools costs a lot. The cooling channel of plastic mold is usually deep hole (diameter 10-16mm, length 500-1200mm), with large processing capacity and vertical processing Center 850 is still not suitable, so special horizontal deep hole CNC drilling machine should be selected, which can complete deep hole processing tasks efficiently and automatically.
The selection of rail vertical machining center should be compatible with the product. How to realize “0” scrap in NC lathe processing? In the CNC lathe processing industry, the ideal goal of each manufacturer is zero waste manufacturing. In order to make supplementary adjustment or feedback control for CNC lathe processing equipment, the dynamic accuracy theory should be studied from the accuracy theory, including the evaluation of dynamic accuracy. This paper studies how to make full use of the measurement information to achieve zero waste production. Through the full use of 100% online measurement data, the dynamic characteristics of error distribution in the process of processing and measurement are analyzed, At the same time, according to the dynamic characteristics of machining error and the accuracy loss characteristics of sensor accuracy, as well as the product quality requirements and tolerance regulations, Dongguan CNC machining center gives the basic theoretical model of zero waste manufacturing, and makes full use of modern mathematical methods such as artificial neural network and genetic algorithm to accurately predict the machining quality, so as to achieve quality control in advance.
In the process of CNC lathe processing, the workpiece can be measured online or 100% detected, which needs to study the test equipment suitable for dynamic or quasi dynamic, and even can be integrated into the special test equipment of CNC lathe processing, so as to achieve real-time test. According to the test results, the process parameters are constantly modified, but in the process of achieving this goal, the role and significance of precision test technology is self-evident. The processing quality of parts and the assembly quality of the whole machine are related to the processing equipment, test equipment (non-standard parts processing) and the analysis and processing of test information. Therefore, zero waste production can be realized from the perspective of precision test To start, we need to consider some problems.
