Tips for Precision Machinery External Processing
The precision machining process specification for precision machinery is one of the process documents that stipulates the machining process and operating methods of parts. It is
Under the specific production conditions, write a more reasonable process and operation method into a process file according to the prescribed form
, Used to guide production after approval. With the technological innovation, senior Beijing machining manufacturers have summarized the following commonly used
1. Remove the jaws of the vise during Beijing machining, and process two M4 threaded holes to make the two pieces even with the jaws.
1.5mm steel plate 2, riveted with 0.8mm thick brass plate 3 with aluminum countersunk rivets and fastened it to the jaws with M4 countersunk screws
Creates durable soft jaws. This also protects the parts from being pinched and is interchangeable.
2. It is inconvenient to use magnets to pick up small parts (expenses) during machining. Can be sucked under the magnet 1
Each iron plate 2 can not only suck a lot of small pieces, but also pull the small pieces away automatically and immediately pour into the collection box. Not enough to hit
Attentive but practical.
3. During the transmission of the pulleys in Beijing machining, the pulleys often slip between the pulleys and the axles.
Use a ￠ 15 ~ 18mm dimple to drill a series of dimples. This can form an adsorption force to prevent slipping and turn waste into treasure. The boss will reward you.
4. In Beijing machining, when the handle of the Allen wrench is short and cannot be stressed, the pipe with a slightly larger inner diameter than the wrench can be removed.
Insert a spanner into a slot for milling a slot. It can be used as a long handle.
In Beijing machining, there are many workpieces that are not produced at one time, but when the workpiece is produced
When it comes out, it is just a rough model. If it leaves the factory to become a real product, some of it will be aided by
Mechanical processing of mechanical equipment and mechanical processing according to different product needs can ultimately become a kind of use price
In order to ensure the efficiency of mechanical processing and the quality of the products produced, it is necessary to perform mechanical processing.
Follow four principles.
1. Benchmark first:
When using mechanical equipment to process the product, a reference plane must be determined, so that during subsequent processing
Only when a positioning reference is available, after the reference plane is determined, the reference plane must be processed first.
2. Divide processing stages:
When the product is mechanically processed, different degrees of processing are required according to different product requirements, and the degree of processing needs to be improved.
Line division. If the accuracy is not high, a simple roughing stage is sufficient. The more progress the product requires
The more stringent it becomes, the more semi-finishing and finishing stages will follow.
3. Face first and then hole:
When machining, for a workpiece such as a bracket, it needs to perform both plane machining and mechanical hole machining.
In order to reduce the accuracy error of the processed hole, processing the plane first and then processing the hole are helpful to reduce the error.
This processing principle is roughly some grinding and polishing processing, which is usually performed after the product has completed the structure.
