Examples of Workpiece Loading
This section is an explanation of the cutting workpiece attachment method when a machine vice is used. If employing an alternative
attachment method, fix the workpiece firmly in place using the following explanation for reference.
Under the standard workpiece attachment method, a block is attached
to the vice, then the workpiece is fixed to the block with double-sided
adhesive tape. This is the most suitable method when cutting com-
paratively small workpieces. For the fixing-use block, it's better to
choose a workpiece that can be cut and aligned horizontally with
precision. (So that after attachment with the vice, accuracy can be
improved when the surface is cut.) When cutting complicated shapes,
it can be difficult to fix the workpiece to accommodate the cutting
process. But with this method you can fix the workpiece setting
position by cutting the block itself to the required shape.
Before fixing the workpiece in place, take away any foreign matter
such as cutting waste from the surface of the fixing-use block. If
foreign matter remains, the workpiece may not be properly fixed and
also the finished dimensions may not be precise.
As an alternative, it is possible to attach the workpiece to the vice
directly. Because no fixing-use block is utilized, this method is
capable of accommodating larger workpieces. In addition, attachment
and detachment are easy. However, this method is not suitable for
very complicated shapes or for cases where the strength of the part
held in the vice is weak.
In cases where the workpiece is attached to the vice directly, be
careful to adjust the cutting depth (the total Z axis feeding amount) so
that the part of the workpiece held in the vice is not cut. If the tool
cuts the vice, the cutting edge of the tool will be damaged and it will
be impossible to use. Also, in the case of a very thin tool, the cutting
edge may break and become very dangerous.
