Introduction: Movement Controls
When using a mill, the material is clamped into a vise or directly to the table. The table is moved so that the workpiece moves past a spinning cutter.
The table can move in 3 directions, called X, Y & Z.
- X is the long horizontal axis
- Y is the short horizontal axis
- Z is the vertical axis
- Handwheels and power feeds move the table horizontally (X & Y).
- Z crank moves the table vertically (Z).
- Locks keep the table from moving.
- Lock each axis that is not moving.
- Unlock an axis before moving it.
- X handwheel (2)
- Z locks (2)
- Y lock
- Z crank
- The quill handle (see below) also adjusts the Z height.
- X locks (2)
- Y handwheel
- Y power feed
- X power feed
Step 1: Head Controls
The head of the mill holds the following controls:
- Hi/low gearbox
- Speed control and display
- Quill handle
- Quill lock
CHANGING THE GEARBOX RANGE
Mill must be off
- Push the lever towards the mill and rotate into high or low range.
- Rotate the spindle by hand to fully engage the gears.
- Move the switch on the control panel to match
the gearbox switch.
- Ex. if the mill is in high range, turn the control panel switch to high.
CHANGING THE RPM
Mill must be on
- Rotate the handwheel clockwise or counterclockwise.
- Observe the RPM on the display.
- Use the brake to stop the spindle after turning off the mill.
- Engage the quill lock before moving the table.
- Use the quill handle to move the quill like a drill press.
- Set the depth stop to limit quill handle travel.
