Production process and technological process of medical parts and accessories processing
1、 Production process and technological process
1. Production process
The process of converting raw materials into products is called the production process, which mainly includes the transportation of raw materials, the storage of raw materials, the preparation before production, the pre processing, machining, surface treatment, assembly, testing, debugging, oxidation prevention treatment and product packaging;
The production process can also be divided into the production process of the whole machine or the production process of a part, which is the production process coordinated by the whole factory or the production process of a single workshop;
2. Process flow
In the specific production process, the process of directly changing the shape and size of the blank material to the relative position and nature required by the product to make it a finished or semi-finished product is called the process flow. The process flow is a very important part of the production process. The main part of the production process of the machining manufacturer is called the machining process flow, The main part of the production process in the assembly workshop is called the assembly process flow;
2、 What constitutes the machining process flow
Processing of medical parts and accessories
1. Preparation of processing procedures
A processing procedure refers to a part of the processing process that one or more parts are processed continuously by an operator or a group of operators at a fixed work place or on a fixed processing machine. The processing procedure is a basic part of the machining process line and the basic unit for arranging production plans;
2. Installation
The part of the process that the workpiece or assembly unit completes after one clamping is called the installation process. Sometimes, in the same process, the workpiece may need to be installed several times to achieve the final goal; It should be noted here that the number of installation times should be reduced as much as possible during the processing, so as to reduce the installation error and save more auxiliary time;
3. Step
When the machining surface of the part, the tools needed for machining, the rotational speed and the feed rate are unchanged, the part of the process that is completed continuously is called a step, which is the basic unit of the process;
4. Station
In order to complete a certain process, after a clamping, the workpiece, together with the movable part of the fixture containing the equipment, is relative to each position occupied by the fixed part of the tool and the equipment. For example, use the dividing head to mill a hexagonal body, and each rotation is a station;
5. Walking knife
In the same work step, if the machining amount is relatively large, it is necessary to use the same tool to make multiple cuts on the same machining surface at the same speed, and each cut is a tool feed.
