What are the advantages and disadvantages of CNC lathe machining center
Do you know the advantages and disadvantages of CNC machining? I will report to you. CNC machining has the following advantages: ① The number of tooling is reduced in large quantities, and parts with complex styles do not require complex tooling. If you want to change the style and size of parts, you only need to modify the part processing program, which is suitable for new product development and modification.
②The processing quality is stable, the processing precision is high, and the repeatability is high, which conforms to the processing requirements of the mobile device.
③The production efficiency is high in the multi-variety and small-quantity production environment, which can reduce the time for production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of cutting amount.
④ It can process complex surfaces that are difficult to be processed by conventional techniques, and even process some unobservable processing parts.
Disadvantages: The disadvantage of CNC machining is that the machine tool is expensive and requires a high degree of maintenance personnel.
In the machining industry, computer gong machining center, referred to as cnc machining, is a highly efficient automatic machine tool composed of machine equipment and numerical control system used to process complex-shaped workpieces. The CNC machining center is equipped with a tool magazine, which has the function of automatic tool change. The machining center is a highly mechatronic product. After the workpiece is clamped, the CNC system can control the machine tool to automatically select, replace the tool, automatically set the tool, and automatically change the spindle speed and feed amount according to different processes, which can continuously realize drilling and boring. , milling, reaming, tapping and other processes, thus greatly reducing the workpiece clamping time, measurement and machine tool adjustment and other auxiliary process time, the processing style is relatively complex, the precision requirements are high, and the types of parts that are replaced frequently have a good economy. Effect. The benefits of processing intermediate processing
During the machining process, after the workpiece is clamped once in the CNC machining center, the digital control system can control the machine tool according to different processes, and the CNC lathe machining automatically selects and replaces the tool, and automatically changes the machine tool spindle speed, feed rate and tool relative to the workpiece. The motion trajectory and other auxiliary functions of the machine are used to realize the processing of multiple processes on several surfaces of the workpiece in sequence. And there are a variety of tool change or tool selection functions, so that the production efficiency is greatly improved.
In the middle of CNC computer gong processing, due to the intensive process and automatic tool change, the time for workpiece clamping, measurement and machine tool adjustment is reduced, so that the cutting time of the machine tool reaches about 80% of the starting time of the machine tool (only 15-20% of the ordinary machine tool) At the same time, it also reduces the workpiece turnover, handling and storage time between processes, shortens the production cycle, and has obvious economic effects. The processing center is suitable for the production of medium and small quantities with relatively complex parts styles, high precision requirements, and frequent product replacements.
