How to improve the machining accuracy of CNC Gang Type Tool

CNC Gang Type Tools are used more and more in automated processing, and the precision is also getting higher and higher. Foshan Micro-control Industrial Automation Technology Co., Ltd. has self-developed CNC system, and combines this advantage to focus on the production of CNC knife arranging machines. So how to improve the machining accuracy of CNC cutter arranging machine? The cost of a CNC cutter arrangement depends on this.

First, we will study how to improve the machining accuracy of CNC lathes from the aspect of mechanical adjustment. In terms of machine tool adjustment, it mainly includes these parts, spindle, bed and inserts, etc., so that the lathe can meet the requirements and improve the machining accuracy of CNC lathes. It must be monitored regularly during the work process, and it must be continuously optimized. Insufficient in lathes in order to adjust in time to produce better products. This is the easiest and most convenient way to improve the machining accuracy of CNC lathes. This adjustment method does not require good skills, but requires employees to check and adjust from time to time.

The CNC lathe automatically processes the parts to be processed according to the pre-programmed processing program. We put the machining process route, process parameters, tool movement trajectory, displacement, cutting parameters (spindle revolutions, feed, back-feeding amount, etc.) and auxiliary functions (tool change, spindle forward rotation, reverse rotation, etc.) Cutting fluid on and off, etc.), write a processing program list according to the instruction code and program format specified by the CNC machine tool, and then record the content of the program list on the control medium (such as perforated paper tape, magnetic tape, magnetic disk, magnetic bubble memory, and then input into the numerical control device of the numerical control machine tool, thereby directing the machine tool to process the parts.

This whole process from the analysis of the part drawing to the production of the control medium is called the compilation of the numerical control program.

The second is the improvement in the electromechanical joint adjustment. To improve the machining accuracy of the parts, it is mainly to improve the reverse deviation, positioning accuracy and repeated positioning accuracy. In terms of reverse deviation, when the deviation is too large, we must first correct it by mechanical and manual methods, and then use professional methods to further optimize when the error is small within a certain range. When adjusting the positioning accuracy, the error is continuously optimized by the degree of the microscope. The electromechanical joint adjustment method optimized in these aspects is the most efficient way of these adjustment methods. Although it will be more complicated, the effect is better.

Third, this is through the adjustment in electrical aspects. The adjustment in this aspect mainly includes two aspects, one is the adjustment of machine tool parameters, and in this angle, there are two aspects that affect the machining accuracy: system gain and positioning the dead zone, in terms of system gain, we should pay attention to the mechanical damping of the lathe and the rotational inertia, which all affect the machining accuracy of the lathe. There is also to minimize the dead zone of positioning, which can also improve the accuracy of the lathe operation. These two aspects are complementary and need to be adjusted at the same time. Another aspect is that it can be adjusted through the application of some systems. Due to the continuous improvement of automation, CNC lathes use automatic remote control during operation, so we need to enter a series of monitoring programs during remote control, so that there is no need for excessive manual intervention, so that supervision can be carried out more effectively, the setting control can be supervised by the program, and the accuracy of the lathe processing can be improved.

The above is a small CNC lathe manufacturer Foshan Micro-control Industrial Automation Technology Co., Ltd. in terms of parts and machine tool adjustment to improve the accuracy of CNC lathe processing, this method is widely used.
