CNC is understood to be newly developed or designed products usually need to make hand plate. Hand plate is the first step to test the feasibility of the product, is to find the design of the product defects. Defects. Defects are the most direct. The most effective way to improve defects is to find no defects in the pattern of an individual's hands. At this point, it usually takes a small amount of trial production to find that the volume is not enough to improve. The design of the design is generally not perfect, even can not be used, once the direct production defects will all be scrapped, a great waste of manpower. Material resources and time; General sample less, short production cycle, less manpower consumption. With few material resources, it can quickly identify the shortcomings of product design, and then provide sufficient basis for product improvement and mass production.

Hand plate model processing skills

1, in a hand plate model processing to complete most or all of the process, reduce the number of workpiece clamping.

2.cnc machining should be positioned as far as possible according to the marking basis of the drawings.

3. According to the material and size of the parts, try to choose the most appropriate tool for processing, to reduce the processing time.

4. In order to reduce tool wear in the machining process of hand plate model. The load of each axis of the machine tool and processing have good surface finish, processing as far as possible to use smooth milling.

5. In the process of processing, the wear and processing time of machine tools should be reduced as far as possible.

6. Adjustable fixture or simple fixture is used for processing single or small batch parts.

7. When processing large quantities of parts, special fixture should be used. Tool. And the fixture should be convenient. Reliable. Quick clamping clamping and positioning.

8. The same processing datum should be used in the processing of the hand plate model.
