Polishing Wax Hand Grinding and Mechanical Grinding Characteristics
The main components of polishing wax: stearic acid, palmitic acid,
oleic acid, rosin and other adhesives, plus abrasives, such as
feldspar powder, chromium oxide, corundum, iron red, etc.,
according to different matrix components and requirements. Fineness
and variety. In daily production, polishing wax is used for
polishing, and we usually divide it into manual grinding and
mechanical grinding according to the operation mode. According to
the way of coating abrasives, it can be divided into dry grinding,
wet grinding and semi-dry grinding. Manual grinding is mainly used
for single piece small batch production and repair work. Manual
grinding is labor-intensive and requires skilled operators and high
technical skills. However, manual grinding is indispensable for
some high-precision workpiece processing. Mechanical grinding is
used in mass production, especially when the workpiece geometry is
not complex. Mechanical grinding is often used. Polishing wax dry
grinding is also known as embedded sand grinding. Before grinding,
the abrasive should be embedded on the surface of the grinding tool
(referred to as pressed sand). When grinding, just apply a little
lubricating oil on the surface of the grinding tool to carry out
the grinding work. Wet grinding is also known as sand-applied
grinding. Before grinding, a pre-prepared liquid grinding mixture
is applied to the surface of the grinding tool, or the grinding
mixture is continuously added to the surface of the grinding tool
during the grinding process for grinding. Semi-dry grinding is
similar to wet grinding in that a paste-like polishing wax is
applied to the surface of the grinding tool for grinding before
grinding. Wet grinding has higher productivity. Whether it is
manual grinding, mechanical grinding, or dry grinding and wet
grinding, the quality of the workpiece to be ground mainly depends
on the grinding method, abrasive, additional abrasive, grinding
pressure, grinding motion and pre-processing before grinding and
other factors. Grinding is widely used.
