HINTS FORSUCCESSFULARBORMOUNTEDCUTTERUSAGE
Some of the many factors governing efficient use of bore cutters
are:-
1)
Condition of machine
2)
Machine power available
3)
Machine capacity
4)
Nature of the workpiece
Attention should be given to these factors prior to commencement.
When using arbor mounted cutters the following points should
be observed:-
Taper drive of arbor should be in good condition and fit correctly
into machine drive.
Arbor and bushes should be kept in good and clean condition;
dirty bushes cause run-out of cutters.
Arbors should be oiled and carefully stored when not in use;
bent arbors are useless and expensive to replace.
Cutters should run true to prevent overloading of one or two
teeth and extensive regrinding later.
Fit the cutter as closely as possible to the machine column with
a support as near to the cutter as the workpiece will allow.
Running bushes and support bearings should be kept clean and
in good running condition, particularly with regard to the bush
faces. Lack of support will cause damage to the cutter and the
workpiece. Always use correct lubricants.
Workpiece clamping should be rigid and able to withstand the
forces acting upon it under the action of the cutter.
Select correct speeds and feeds for the cutter in use and the
nature of the workpiece material and the size of the cut to be
taken.
