Provide machined products
Molding workshop
Equipped with 20 forming mills and 1 automatic mill
Technological process
1. Incoming inspection: use micrometer to check whether the incoming dimension is consistent with the product specification on the processing drawing and construction sheet.
2. Confirm the equipment status and check whether the water circuit is normal. Before starting the machine, check the equipment, add oil and lubricate the equipment according to the regulations, check whether the oil pressure, oil circuit, oil volume, etc. are normal, and whether the oil quality is good
3. Preparation for arc grinding: Inspection and repair of grinding wheel; installation and inspection of fixture; opening of water pump; opening of grinding head.
4. Loading, trial grinding. The workpiece shall be put into the fixture for grinding in turn. Let the product rough grind first, and then gradually grind to the required size.
5. Batch grinding. After the trial grinding products are qualified, they can be processed in batches
6. Inspection: according to the processing order and drawings, check the size of the ground products, and place the qualified products and unqualified products in different designated areas. Record the first inspection, patrol inspection and completion inspection.
7. Shut down and clean. Shut down the machine, put the auxiliary tools and measuring tools in the designated position, and clean the surrounding of the equipment.

Provide machined products
Wire cutting workshop
Technological process
1. Polish one side of the machined part and use 502 glue to stick the flat surface of the machined part to the prepared iron plate.
2. Adjust the fixture to a proper position, open the cutting fluid, and make it spray on the cutting position of molybdenum wire.
3. Observe the spark between molybdenum wire and workpiece, which should be in the best starting state during operation.
Advantages of bonding magnetic steel technology
Reducing eddy current heating of magnetic steel
The eddy current effect can be greatly reduced and the working temperature rise of the motor can be reduced by 5 ~ 10 ℃ by bonding the magnetic steel
