A template is therefore necessary, as well as a protecting device repairing the cutter
as much as possible. Two retainers must also be used at the two ends.
The template must enable a piece fast and accurate positioning, as well as being tightly
hold.
The most practical method for locking the piece is using fast locks operating with levers
or cams.
Some front and rear retainers fastened on the guides or on the table enable a better
template control; the loading/unloading can be made by a second template fastened
on the first one.
4.6.10 Shaft machining
A template must be always used when machining with the shafts, unless the operation
type does not enable it; that is, when the piece is so large that adding a template makes
the machining impossible, or when the piece is so small or so complicated that it cannot
be safely held in the template. For most of the shaft machining a template is used for
the finished piece contour.
The finished shape is achieved by keeping the template against a roller bearing, while
the piece meets the tool.
4.6.11 Simultaneous machining
It is absolutely recommended not to operate with simultaneous machining because the
rejection risk increases.
4.6.12 Other machinings
When other types of machinings are made, such as tenoning and butting, suitable tem-
plates or supports can be used for reducing the risk of accidents.
The following accessories can be used for aiding the operator during the machining:
•
templates
•
pushers
•
movable feeders
•
extension tables
•
retainers and rip fences.
4.6.13 Noise reduction
•
The tool conditions are very useful for reducing the noise level.
•
The materials and the positions of the protecting devices must aid in reducing
the noise level.
•
The tool speed must be chosen so as to reduce the noise level.
•
The use of personal protections must integrate the use of those mentioned
above.
