Copper quality precision machinery parts processing roughening solution soft copper material itself, precision machinery parts processing, using this kind of material can be achieved by heat treatment to improve the hardness, but its machinability is poorer, because the class precision parts
grinding abrasive dust plug copper wheel blowhole, so generally need not grinding method for copper precision machinery parts processing.
Transformers can be used car (
Cutting mode, the tip trajectory by precision parts shape precision and surface quality, under the influence of cutting principle, for the high machining accuracy of precision parts and components, it is hard to meet the technical requirements.
For surface quality and shape accuracy requirement of high precision parts and components, copper to meet the quality requirements should be carried out in accordance with the precision machining process of grinding, but cannot copy the common parts processing technology, not only will not solve the problem of wear debris jam grinding wheel, but also can appear hair scratches on the surface of the precision parts and components, which reduces the precision machining quality.
For workpiece, the hair is the main reason affecting the quality of processing, clear surface roughening copper is a precision machinery parts processing to solve the main technological problems.
What is hair?
Shown is the uneven distribution of workpiece surface in the same direction and deep scratches called hair, surface roughness increases after hair, affect precision of parts.
How to solve the problem of hair, is also solve the copper parts precision machining center.
To solve the problem of workpiece of roughcast, should how to avoid the hard particles into the grinding zone, to avoid hard particles into the grinding zone, ensure the quality of the workpiece surface is improved from the following several aspects: 1.
Choose granularity coarser grinding wheel, can make the sharp and abrasive micro blade more, easy cutting, to reduce the processing of the grinding wheel effect of grinding force on precision machinery parts processing.
Choose moderate hardness of the grinding wheel, grinding wheel hardness refers to the action of external force of abrasive loss, to the difficulty of the copper parts processed with medium hardness of the grinding wheel can prevent the grinding of abrasive particle loss.
Choose organization is relatively loose of the grinding wheel, the grinding wheel group, have larger pores between abrasive, can store more cooling fluid, prevent wear debris blocking grinding wheel, and also has good heat dissipation performance.
Appropriate increase the flow of cooling fluid, make it to the grinding wheel has good cleaning effect, prevent the chip block grinding wheel blowhole and wash away the groceries, but also to enhance the cooling effect, timely take artifacts by cutting heat, guarantee the stability of workpiece size.
