I. Acceptance requirements

1. Appearance inspection

Check that the finish of the machined part meets the requirements of the drawing.
Check whether the machined parts are free from damage, rust, bruising and whether the thread shape and angle are correct.
If any of the above problems are found, a detailed record should be made for inspection.
2. Quantity acceptance

Check the material, specification and quantity of the machined parts strictly against the drawings, using the supply contract and processing vouchers as the basis, and check them piece by piece.
Make a good record of quantity acceptance, stating the acceptance place, time, participants, type, product name, quantity due and actual arrival.
3. Quality acceptance

The assembly should be carried out in strict accordance with the regulations and procedures required by the general assembly drawings.
Records should be made carefully during quality acceptance. If there is a quality problem with the workpiece, the external processing unit should be informed in writing of the details. Depending on the situation, decide whether to return or replace.
In the case of special requirements, the processing unit can be found to jointly inspect and assemble, and the acceptance document can be signed only after the installation is qualified.
Second, acceptance procedures

After the mechanical processing parts are received, both the full-time acceptance personnel sent according to the contract against the requirements of the drawings on the material, specifications, models, quantities of processed parts for acceptance.
Acceptance period is generally 1-2 days. Special circumstances are determined by the use of the effect. If there are quality problems, the processing unit can be returned, claims, processing units bear economic losses.
General processing contracts not signed by the production section will be accepted directly by the department used to fill in the acceptance report.
Acceptance of unqualified parts, acceptance staff must be within the specified acceptance period to overhaul, return procedures.
Acceptance of special precision machined parts will be organised by a full-time acceptance officer who will jointly inspect the relevant personnel and fill in the acceptance report form in detail. Acceptance of unqualified parts to fill in the details of the report form, as a requirement to improve the conditions of processing accuracy and determine the future of the choice of outsourced processing parts manufacturer direction.

What are the common equipment used for machining precision mechanical parts?

What are the common equipment used for precision machining? Precision machining is a process of changing the size or performance of a workpiece with machining machinery. According to the temperature state of the workpiece being machined, it is divided into cold machining and hot machining. Generally processed at room temperature, and does not cause chemical or physical changes in the workpiece, called cold machining. Machining at temperatures above or below room temperature generally causes chemical or physical changes in the workpiece, known as hot machining. Cold working can be divided into cutting and pressure machining depending on the processing method. Hot work is commonly done by heat treatment, calcination, casting and welding.
