There are several processes for sample: CNC processing samples, 3D printing samples, silica gel replica samples, sheet metal samples, low-pressure injection samples, etc.Let’s briefly describe the pace and advantages of CNC processing samples.
Many people also call it the first mold for sample. Generally speaking, after an industrial product is designed, it is not put into manufacturing as soon as possible, but should first manufacture a small number of sample according to the drawings. The goal is to see the samples of the shaped products in advance. If not, then modify the drawings until there is no objection, and then start batch manufacturing. This small mold is the sample in the mouth.
The steps of CNC processing sample as follows:
1) Discuss the CNC processing value and delivery date, and sign the processing agreement.
2) Analyze the part drawing and product configuration drawing, and analyze the process of the part.
3) Select the blank.
4) CNC sample programming.
5) Confirm the machining allowance of each process, calculate the process size and yamen service.
6) Confirm the equipment and tools, clamps, measuring tools and auxiliary equipment used in each process.
7) Confirm the cutting amount and working time quota.
8) Confirm the technical requirements and inspection methods of each key process.
9) Fill in the process documents of CNC machining sample proofing.
CNC processing sample has the following advantages:
① Complex tooling is not required. If we want to change the form and size of the parts, we only need to modify the processing program of the parts, which can be used in the development and modification of new products.
② The processing quality of sijunda sample is stable, the processing precision is high, the repeated precision is high, and it is suitable for the processing requirements of high-precision products.
③ Under the condition of batch manufacturing, the manufacturing efficiency is higher, which can reduce the time of manufacturing planning, machine adjustment and process inspection.
④ It can be used to process complex surfaces which are difficult to be processed in conventional way, and even to process some processing parts which cannot be observed
