Using the machine-
mounted emergency
stop button.
There is an Emergency Stop button located on the front panel of
the milling center; it has an oversized red cap.
To engage: Press the button in.
To release: Turn the button clockwise, it will pop out on its own.
Using the software
stop button.
The execution of the part program can be interrupted by
pressing the Control and Spacebar buttons on the computer
keyboard. Unlike using the Emergency Stop button, this method
of stopping the milling center does not cause the software to
lose track of the tool position.
Operation Rules
General
Proper setup of the milling center is essential for safe milling.
These procedures must be followed each time a new tool is
mounted. General setup requirements for the milling center
include checking components for cleanliness and lubrication,
mounting the cutting tool, mounting the workpiece, and setting
the spindle rotation speed.
Avoid accidental
starting.
Make sure the power switch is off before plugging in the milling
center power cord.
Check milling machine
components.
Always examine the machine to be sure that the work area is
free of shavings and particles from previous operations. Remove
such debris from the milling machine to avoid possible binding
of components which may result in possible damage to the
milling machine, the workpiece, or the operator.
Always make sure the machine is properly lubricated.
Do not force a tool.
Select the feed rate and depth of cut that are best suited to the
design, construction, and purpose of the cutting tool. It is
always better to take too light a cut than too heavy a cut.
Use the right tool.
Select the type of cutting tool best suited to the milling
operation. Don't force a tool or attachment to do a job it wasn't
designed for.
Maintain cutting tools
in good condition.
Keep cutting tools sharp and clean. Lubricate and clean milling
center components on a regular basis.
Mount the cutting tool
correctly.
Each cutting tool used in the milling operation must be sharp
and properly installed in the spindle. The cutting edge of the
tool must be on the centerline or just below the centerline
(0.004 inch or 0.1 mm maximum) of the axis of rotation of the
milling machine
Secure the workpiece.
Be certain that the workpiece is firmly clamped to the table or
secured in a vice.
Tighten all holding,
locking and driving
devices.
Tighten the work holders and tool holders. Do not over tighten
these devices. Over tightening may damage threads or warp
parts, thereby reducing accuracy and effectiveness.
Turn the spindle by
hand before starting.
Manually turning the spindle allows you to safely determine
that the tool will not hit the milling center bed, cross slide, or
stock on start up.
