Cemented carbide rotary burr is widely used in machinery, automobile, shipbuilding, chemical industry, craft carving and or industrial sectors, with remarkable effect. And it is a very important industrial process tool. Cemented carbide rotary files are very important in industrial processing and production. Nowadays not only industry, rotary files are also used in dentistry and medical beauty industries. People use it as an important means to improve production efficiency and realize fitter mechanization. Cemented carbide rotary burrs are very important in industrial processing.


At present, overall average value of each industry is very conducive to completion of cemented carbide burr processing operation.Tungsten carbide rotary burr can also be used to make rock drilling tools, mining tools, drilling tools, measuring tools, wear-resistant parts, metal abrasives, cylinder lining, precision bearings, nozzles, hardware molds (such as wire drawing dies, bolt molds, nut molds, and various fastener molds), and excellent performance of cemented carbide has gradually replaced previous steel molds.

Development of carbide burr

 

In past 20 years, coated cemented carbide has also come out. Titanium carbide coated tool was successfully developed in Sweden in 1969. Substrate of tool is tungsten titanium cobalt cemented carbide or tungsten cobalt carbide. Thickness of titanium carbide coating on surface is only a few microns. However, compared wit same brand of alloy tool, service life of tool is prolonged by three times, and cutting speed is increased by 25% - 50%.


Konetool continuously feels urgent need of customers for excellent advanced experience sharing, so we pay more and more attention to introducing advanced processing knowledge and sharing processing experience to customers in our daily work. Products are hardware, knowledge is software. Only by combining two can we provide comprehensive services for customers, and truly support customers to improve production efficiency and reduce production costs.

As the file is installed on the grinding machine and controlled manually during operation, the pressure and feed rate of the file are determined by the working conditions and the experience and skills of the operator. Although a skilled operator can control the pressure and feed speed within a reasonable range, here is something to explain.

 

 It is necessary to replace or sharpen the shortened sand head in time to prevent it from being completely destroyed. . The sharpened head is very slow to cut, so the pressure of the grinder must be increased to increase the speed, and this will inevitably increase the damage caused by the filing and the grinder. The cost of the loss is much greater than the replacement or The cost of heavy sharp grinding head.

Function relationship between geometric shape of rotary file and coordinate axes of NC machine tool in NC machining of all kinds of rotary files provides a mamatical model for controlling various kinds of rotary files. According to control model established by this mamatical model,  workpiece which can meet requirements of drawing can be machined on multi coordinate simple NC machine tool.

 

Cemented carbide rotary burr is widely used in mold processing and or bench work. Although  size of rotary file is not large, due to complex edge shape, as well as a variety of specifications, due to more teeth, complex profile, and various specifications, grinding of carbide burr has become a difficult problem. In order to solve this problem, a set of CNC system based on industrial PC (IPC) is developed in this paper, which is based on four coordinate rotary file grinding machine developed.

According to grinding motion model of rotary file, system realizes CNC grinding of cemented carbide rotary file by combining software with hardware. This paper first introduces overall structure of two kinds of four coordinate rotary file grinding machine tools, and makes a comparative analysis. n, combined with machine tool structure, after analyzing  feasibility of four coordinate grinding of rotary file, fifteen kinds of mamatical models of rotary file grinding motion are established. According to functional requirements of rotary file grinding and current development of open CNC system, control scheme of IPC machine motion controller driver stepping motor is adopted. According to this scheme, required hardware is selected and connection between each hardware module is completed. At  same time, design scheme of NC system software is determined, and programming of CNC grinding system software of rotary file is completed.


After working out processing scheme of rotary file, CNC system is used to carry out multi coordinate linkage control on  four axis rotary file grinding machine tool, and a large number of practical grinding tests are carried out for various types of rotary file. Through actual grinding, correctness and feasibility of grinding motion model of rotary file are verified. At present, first CNC grinding machine based on IPC developed by school of mechanical engineering of Tianjin University has been put into practical use.
