At present, many companies that
have higher requirements for printing have a polyurethane rubber roller, which
has good wear resistance and elasticity, and the production technology of the
product is mature, and people can process grinding in the process of using
rubber rollers. Process is a roughly understanding.
Here's details of the grinding
process and parameter selection of the polyurethane rubber roller in detail:
First, for the machine tool, the
accuracy of the spindle is detected and adjusted, and the factory accuracy is
reached; the grinding wheel is balanced to reduce grinding. Adjust and detect
the mandrel of the mounting parts to ensure within design tolerances.
In order to ensure the processing
accuracy and the table and roughness requirements, you can choose two grinding
methods:
(1) Once grinding type. That is, after trimming the outer arc of the grinding
wheel with the diamond wheel, it is directly grounded to the dimension. As a
result, when the grinding wheel particle size is large, the grinding efficiency
is high, but the surface roughness of the polyurethane rubber roller is
difficult to achieve; when the grinding wheel particle size is selected, the
surface roughness is required, but the grinding efficiency is low.
(2) Working with the way to polish first. After rough grinding, leave
0.01 ~ 0.02 mm margin, polished with a blank wheel. Since the polyurethane
rubber roller rollers are wear resistant. Among them, the process of coarse
grinding and refining is used, and the PVA grinding wheel with polishing effect
is used in fine grinding, which combines fine grinding and polishing, and the
processing is completed, which not only guarantees accurate requirements, but
also high efficiency. When choosing a grinding wheel, it is necessary to
consider maintaining a circular arc shape and considering processing
efficiency. At the same time, due to the small amount of balance, the surface
roughness cannot be too high.
