What are the techniques for precision machining parts

Complex shape, high precision of size and shape, most of the plate thickness t > 3mm ~ 5mm, for the medium-thick plate fine blanking parts, blunt surface flat, smooth and clean, quality comparable to mechanical processing.

Electromechanical products have entered mass production and reached the medium economic production scale of parts including: trucks, cars, motorcycles and other fine blanking parts, all from raw materials a die stamping, without mechanical processing.

Due to the effect of cold-working hardening, the hardness and strength of precision blunt surface is greatly improved; novelty resistance and weather resistance are improved. The life span of fine blanked parts such as gear tooth profile, bushings for moving surfaces, and friction surfaces will be improved.

Fine blanking thin plate outline clear, collapse angle small, part of the hole distance (wall thickness) ≤ t, the formation of flare, countersunk holes, blind holes, wheel flange fine blanking. In particular, precision gear fine blanking parts, such as involute, cycloid, triangular, rectangular, very small modulus trapezoid, etc., is difficult to produce by other machining processes.

Tips for precision machined parts

What are the production and processing characteristics of precision metal machined parts? What contribution do its performance characteristics make to the quality finish of machined parts? The main features of precision metal processing parts are precision automatic lathe, 5 groups of tool holders, and high precision of parts through micrometer card fine adjustment. More than 10 tools can be assembled according to the parts processing process.

Dual-axis device: The spindle adopts electromagnetic clutch to drive the tapping spindle, using the high-speed rotating spindle and the machine tool spindle in the same direction of the rotating gap for tapping. The dual axis can be shaken to change the processing. Internal and external reaming and tapping can be completed simultaneously. External threads can be processed by milling device, solving the problem of difficult mold processing and processing double threads. Precise structure and production control by cam. Parts are machined in one pass by cam rotation. The cam speed is 1.0~36 revolutions per minute. It can be adjusted according to different machining parts. 36 parts per minute can be machined at the fastest speed.

Technical performance of precision metal processing

Significantly improves the resistance to thermal melt damage of alloy die casting dies.

Improved mold release performance and corrosion resistance.

Improved thermal fatigue resistance of die casting dies.

Significantly improve the service life of alloy die casting dies.

The color is visible. User can repaint according to the change of coating color. Can protect valuable precision metal precision machined parts.

Precision metal machining parts are completed because 5 machines and 2 boat tails work simultaneously during the machining process. So this machine tool is 4~6 times faster than CNC machine tool. It can process cylindrical surface, spherical surface, conical surface, circular arc surface, step, grooving, drilling, tapping, mold, embossing, cutting, etc. Finish all the machining process at one time. High machining accuracy, no manual operation, fully automatic feeding, one person can operate more than one machine tool.
