How To Avoid Burr in Design of Metal Machining Process
How To Aviod Burr in the Design of Metal Machining Process, we believes that measures technology will be better explaination, In mechanical processing, production of burr is inevitable, and the existence of burr will seriously affect the product quality and precision. And at the same time it will produce some side effects on parts inspection, assembly, operational performance, service life, safety and appearance. In actual work, if deburring method is appropriate, it will improve product quality and reduce cost, otherwise, not only influence the improvement of production efficiency, product quality, will also affect the cost of the product. So we should avoid the burrs during machining process. Creatingway specialized in CNC machining for more than 10 years, we will share more these tips of design of metal machining process very often.
The basic measure of avoiding burr in design of Metal Machining Process
-
Product structure design
To meet the requirements of product use, structure of the product should be able to suppress or reduce the occurrence of burrs. For example, see below after changed the outlet oil hole to a straight hole, the burr problem has been solved well.
-
Adopt reasonable processing method
In the process of metal cutting, the size and shape of the burrs are different. In process design, we should choose the machining method which produces the smaller burrs. For example, in machining flat surface, it is better to use the mill than the reverse milling.
-
Arrange the processing sequence reasonably
When arranging machining sequence of parts, It should be possible to arrange the process of producing burr generated in the front, and the smaller burr produced process later. The process of the posterior process is used to remove the burr generated by the preceding process. For example, it is reasonable to change the machining sequence of the key slotted shaft parts to the first after milling.
-
Reasonable choice of cutting amount
In the cutting process, the burrs produced are larger when processing the large cutting. Because of the larger cutting, the durability is reduced and also increases plastic deformation, which lead to the generated burr becomes larger. Therefore, in the machining of parts, it is generally used to reduce the cutting depth and cutter amount to reduce the production of burrs, especially the precision machining of parts.
There still other ways to control and solve the burr problems, anyhow to provide customer high quality parts, we pay attention to every parts from Creatingway’s CNC machining production line. Pls view more from our blog, Creatingway will share more to you by next article.
