Precision parts processing, what are the benefits of precision parts processing? What are the precision requirements for precision parts processing?

Precision parts processing requires precision and precision. From processing to completion, there should be no problems. When applied to aerospace science and technology, or other metal equipment, mechanical equipment, quality problems must be guaranteed and cannot be guaranteed. The product has a certain impact on the reputation of the manufacturer, or the workmanship, and so on, so precision parts processing is indispensable.

(1) Rough turning: first use the cross-groove turning tool to rough-turn the shape of the two ends of the part. Since the cross-groove turning tool has low resistance and easy chip breaking during the cutting process, the cross-groove tool is used to roughen the shape of the two ends. better. However, because titanium alloy materials are extremely hot deformed during processing, cutting fluid must be used for sufficient cooling during the cutting process.

(2) Semi-finished turning: After the part is completely cooled, use the external offset knife to turn the reference outer circle of the part, clamp the shape of the part with soft claws, and use the micrometer lever to correct the shape of the part. For precision machining, it cannot be processed in place at one time.

(3) Fine turning: After the part shape allowance is cut off, drilling and boring holes are required to ensure the size and accuracy requirements. Calibrate the shape of the parts again to ensure that the dimensional accuracy is within 0.003mm, and the fine turning shape leaves a margin of 0.05mm. Since the double top uses the inner holes at both ends as the positioning reference, and the shape margin of the part before final finishing is small, the drilling, boring and finishing shape are completed in one clamping and centering, and the hole is chamfered. Prepare for the next double top process.

Precision mechanical parts are made of titanium alloy materials, and the requirements for the accuracy of the shape of the parts and the size of the hole are very high. The surface roughness is required to be precision machined on the grinder under normal conditions, so as to achieve the requirements of the drawing, so Said to achieve the surface roughness and tolerance data of the drawings provided by the customer. Professional staff is very important. Good staff can achieve about 90% of the workmanship in this area.
