Non-standard parts processing When selecting a tool, make the size of the tool adapt to the surface size of the workpiece. In
the production, the peripheral parts of the contours of the processing,
often using end mills; milling plane, should be selected carbide cutter
cutter; processing boss, groove, the election high-speed steel end
mills; processing rough surface or rough Hole, you can choose to set the carbide cutter blade of the
corn cutter; for some three-dimensional profile and variable bevel
contour contours of the processing, often using ball cutter, ring
cutter, tapered cutter and disc cutter.
In
the free surface (mold) non-standard parts processing, the end of the
ball tool cutting speed is zero, therefore, in order to ensure the
processing accuracy, cutting line spacing generally use the top close,
so the ball head is often used for surface finishing. The
flat head tool in the surface processing quality and cutting efficiency
are better than the ball knife, so, as long as the guarantee is not cut
under the premise of both the rough surface processing or finishing,
should give priority to the choice of flat knife. In
addition, the durability and accuracy of the tool is extremely relevant
to the tool price. It must be noted that, in most cases, the choice of
good tool increases the tool cost, but the resulting improvement in
processing quality and processing efficiency , You can make the whole processing costs greatly reduced.
In
the non-standard parts processing center, a variety of tools were
installed on the knife library, according to the provisions of the
program at any time for the election knife and tool change. Therefore,
the standard tool holder must be used so that the standard tools for
drilling, boring, expanding and milling are quickly and accurately
mounted on the machine tool spindle or magazine. The
programmer should be aware of the structural dimensions of the tool
holder used on the machine, the adjustment method, and the adjustment
range to determine the radial and axial dimensions of the tool during
programming. At
present, China's processing center using TSG tool system, the handle
has a straight handle (3 kinds of specifications) and taper shank (4
kinds of specifications) 2, including a total of 16 different purposes
of the handle.
