Correct process of machining

Correct process of machining

Today we are going to talk about the correct process of machining

First, after receiving the customer's drawings, check the size of the workpiece, confirm the data, the technical requirements of each size and whether the shape of the public service needs to customize special tools, drill, reamer, fixture, etc.

Confirm all kinds of machine tools according to machining accuracy of machining parts.

Organize production cycle and delivery time after confirmation.

Two, processing should strictly implement the << general process Code of cutting >> blank body to the factory, check the drawings first each shape size, blank hole, groove whether there is processing allowance, deformation, cracks, pores, sand holes and other phenomena, in order to meet the processing quality requirements. Processing is prohibited.

According to the requirements of the drawing, the maximum plane to find work is "processing base". Note: The whole plane may not be visible. Then processing each relative step, hole and groove with a datum surface. In the process of processing, should consider the next process of clamping, calibrating epitope and each size of the processing residual, as far as possible not to repeat the side of repeated processing. Such as vertical milling, side milling on the side, step, slot, hole, point should be completed once. When manufacturing, we should learn to self-check the size of each piece, more than five pieces, we should report to the quality department for first inspection.

Three, large workpiece lifting flanging, should strictly implement the rules of "operating safety rules", take protective measures (plate, tire, pad), prevent the workpiece bump, scratch and shortcomings.

Adhere to daily calibration of measuring tool value (dosage block, standard calibration rod, ring gauge, Angle gauge) wipe clean measuring tool, adhere to measuring accuracy.

The use of knives should be carried out according to the principle of who uses who is responsible for keeping. Rough and fine cutting, fine cutting, fine cutting. Die-cutting tools are kept by specially-assigned person. When wearing, it should be stated to the supervisor and request for grinding repair in time. Unable to use the cutting tools, should be in the team leader or supervisor consent, to the warehouse processing of the old for new procedures.

Four, in the process of milling, boring, drilling and turning, we should first check whether each size conforms to the requirements of the drawing. When there is a problem in the previous process, the team leader and the supervisor should be informed in time to deal with it. After correction, the next process can be processed.

Boring, boring, drilling, milling machine to be flexible, do not require a workpiece after processing a workpiece to drill, tap teeth. No follow-up processing of the processing surface, the process all processing surface content can be finished.

Five in the processing of complete parts, to burr, chamfering, chamfering, scrub clean, sent to QC inspection of each size.

Use the air gun to blow away every hole, step, tooth hole, groove cavity and other debris such as iron. Apply anti-rust oil, put into storage for hair replacement (heat treatment, grinding, blackening)

Vi. Pack well and organize shipment.
