Cutting speed and
choice of tools
The cutting speed depends on the disk rotation speed and supply speed. This
chapter illustrates the speed tolerance of the basic version of the machine.
Cutting speed
Basic version
The inverter is an electronic instrument fitted to the
TIGER 370 CNC---MR
for
varying spindle motor rpm. This device facilitates the operator’s task to execute
special cuts, by adapting the rotation speed of the tool to the specific material.
Blade use can thus be optimised, inasmuch as a blade not especially suitable for
cutting a certain material can be adjusted all the same to the task, and premature
wear is avoided.
The basic version, with 4---pole motor and inverter, has this range of cutting
speeds:
H
15
÷
150 rpm.
The speeds can be set on the control panel via a potentiometer.
The speeds can be set on the control panel via a
potentiometer.
