Traditional machining method of keyway in hole

1. When machining blind hole keyway, only "planing" machining method can be adopted.

2. It is troublesome to process axial straight grooves for blind holes. Generally, it can only be solved by linear reciprocating motion.

3. Because it is a reciprocating machining mode, there must be a chip groove at the bottom of the groove, otherwise it is not easy to break chips.

4. If the aperture is relatively large and the distance between the bottom of the groove and the bottom of the hole is relatively large, the small angle head can be designed and processed on the milling machine.

5. If this structure can be avoided in the design, try not to use the keyway in the blind hole.

The traditional machining method mainly adopts slotting machine, and the machining accuracy is 0.20, which requires marking and alignment, and the machining efficiency is high. Nowadays, more and more wire cutting machines are used, the machining accuracy can reach 0.02, and the comprehensive cost is lower than that of slotting machine. WEDM machines are particularly easy to find, but slotting machines are not easy to find. Therefore, WEDM is recommended, which can be processed by several machines at the same time to ensure the production cycle.

Extended data:

In the production process, the process of changing the shape, size, position and properties of the production object to make it a finished product or a semi-finished product is called a technological process.

It is the main part of the production process. The process can be divided into casting, forging, stamping, welding, machining, assembly and other processes. The mechanical manufacturing process generally refers to the sum of the processing process of parts and the assembly process of machines.

Other processes are called auxiliary processes, such as transportation, storage, power supply and equipment maintenance. The technological process consists of one or several continuous processes, and one process consists of several processes.

The machines needed for processing include digital display milling machine, digital display forming grinder, digital display lathe, spark machine, universal grinder, machining center, laser welding, middle wire cutting, rapid wire cutting, wire cutting, cylindrical grinder, internal grinder and precision lathe.

It can be used for turning, milling, planing and grinding precision parts. This machine is good at turning, milling, planing, grinding and other processing of precision parts, and can process all kinds of irregular parts with a processing accuracy of 2 microns. ..
