How to effectively reduce the scrap rate of Dalian parts processing?

In the process of processing, the current Dalian parts processing factory often pays more attention to some details and technological processes in the process, which is also what the manufacturer will pay more attention to, because it is related to whether the precision parts are finished products or waste products, which is an important guarantee of product quality.

In the actual process of precision parts processing, many mechanical equipment processes and technical engineers' professional skills and key abilities can be well reflected. How to be correct, effective, low-cost and efficient? High quality design is a part processing process and a good performance of a powerful technical engineer's technical expertise. Therefore, precision parts processing under normal circumstances, We should pay full attention to the process flow of parts and strictly abide by the process flow level of parts.

However, some operators still like to change this clear process. Sometimes, this change is based on a self righteous judgment cognition. Operators in the process have the vision and capabilities of a single process. They plan the processing of all parts from the overall processing of a part. In terms of the selection of processing benchmark, the embedding of processing capability and the adjustment of main processing parameters, there are many deficiencies in the selection of NC cutting tools in these fields. The solution is to ensure the processing quality of parts.

A qualified part processing process must not only take into account the processing machine and equipment of the parts, but also take into account the processing method of the parts, the processing of CNC blades, the main processing parameters, the clamping fixture, the refrigeration and lubrication, the processing capacity, the processing flow and sequence, the selection of reference points, the detection method and the formulation of special tools or uniforms, To a large extent, it depends on the cost, quality and efficiency of parts processing. It is also a demonstration of the level of a qualified mechanical equipment process engineer.

The main reasons for Dalian parts processing are as follows:

1) Unbalanced production line

2) High machine failure rate

3) Insufficient material supply

4) The manufacturing process is not smooth and the process arrangement is unreasonable

5) Unreasonable personnel arrangement and inappropriate production plan

Solution or avoidance:

1) Ability to balance the production process

A. Reasonably arrange the equipment. The equipment shall be arranged into a production line system that connects with each other according to the working sequence of the workpiece

B. Generalization of special equipment, adding processing fixtures on special equipment to process a variety of different parts or finished products

C. Formulate standard operation, rationalize operation sequence and operation specification

D. The capacity of each process shall be matched to ensure the smooth flow of materials

E. Small production setting time to reduce dead time

2) Workflow synchronization

3) Meeting punctuality

4) Reasonably allocate production line employees
