Precision Machining Parts Improve The Production Efficiency And Quality Of Parts
Oct 23, 2017

When cutting the precision parts, often because of the coordination between the left hand and the right hand uneven, size control of the sense of responsibility is not strong, measurement technology and weak grasp of the factors caused by the parts of the cutting size is not accurate (the largest gap is basically in 3-4mm above), surface roughness, does not meet the precise requirements of instruments and equipment According to the relevant data of sawing skill training,Precision Machining Parts the deviation of sawing size accounted for about 56%, the existence of the deviation in about 23%, from the overall point of view does not meet the precision parts standard of about 21%.

(2) The problem that the saw blade breaks or the seam is skewed

When machining precision parts, due to installation location error, blade not properly installed, clamping force is unsuitable, processing control force and pressure, saw bow plane distortion, plumb and machining interface, such as the factors leading to the workpiece in the process of sawing,Precision Machining Parts sawing imbalance, saw blade broken and other problems occurred frequently. This greatly affects the manufacturing efficiency and benefits of precision parts, increases the cost of manufacturing and maintenance, and is not conducive to precision instruments or the development of equipment that requires precision parts.

3.2 Fitter's Precision Machining Parts skill

(1) processing technique of Welding belt

Weld Belt as a precision part of the equipment, the required material specifications are higher, generally 0.2mm, wide 25mm±0.05mm, long 1300mm±0.5mm of hot red copper t2y, more use of planer, rolling knife for processing tools, its skills in addition to the need to produce two-block flatness similar, High flatness of the pressure plate, but also need to be mounted up and down the rolling belt knife on the rolling machine up and down two spindles, but also need to adjust the horizontal longitudinal position between the two to ensure that the gap in the range of 0.005mm-0.01mm. The use of such processing skills, not only to fully meet the requirements of the design drawings, but also to improve the production efficiency and quality of components, reduce material loss, and save production costs.

(2) The processing skill of the balance screw

In a wide range of Precision Machining Parts, the balance screw because of its deep opening groove, small width, small size tolerances such as the requirements of the processing process is difficult (prone to scratches, the appearance of the size of the poor), technology breakthrough process slow. From the traditional processing technology, combined with the existing measurement tools,Precision Machining Parts can be before the processing of the mold polishing and opening groove lubrication, but also can design a clamping fixture, in the processing of the workpiece and the tooling at the same time to be processed (there is a small gap between the tooling and workpiece), so not only improve the rigidity of the opening groove, Reduce the probability of deformation, but also to meet the requirements of the accuracy of components required.

(3) processing technique of resistance heat sink

Resistance fins are the most common in precision parts the most practical and widely applicable part of the material is the thickness of 0.8mm 5a06, is generally used in stamping die for professional stamping stereotypes, is to overcome the stamping process in the precision of the size of the accuracy of the grasp, clamping difficulties and other obstacles, Combined with progressive material technology,Precision Machining Parts the processing material can be replaced with crwmn, and the hardness will be adjusted to the 48-55HRC range. This not only shortens the processing cycle, reduces the damage and cost of the material, but also improves the quality of the product, improves the apparent quality, and provides a new idea for small batch production.

(4) Introduction of sine measurement

Sine is a precision measuring tool for the relationship between the taper or the angle, the gauge block and the trigonometric function, which is composed of two precision cylinders and a precise working plane body, which is able to locate the parts in the machining zone angle in the machine tool processing. In the processing of precision parts,Precision Machining Parts it is placed on the sine plate, the opposite flat on the sine plate on the workpiece positioning, the final required size of sine height and the size of the workpiece measured. Through such measurements, you can strictly control the precision parts of the shape and size of the tolerance, can pinpoint the position of error, and can easily get accurate data of the workpiece.

(5) Late maintenance skills of precision parts

Precision parts are essentially a key component of the equipment involved, the internal use of quality and external aesthetic requirements are higher, this need to be packaged in parts after the use of a separate sealed packaging method, but also need to use gasoline or alcohol to wipe (wearing gloves for work) and blow dry,Precision Machining Parts with cotton isolation. This will protect components from perspiration, air and other components of erosion, to ensure that it has been in the factory state, improve its use of time.
