4. OPERATION
This overview gives you the basic process that happens during an operation with this mill.
Familiarize yourself with this process to better understand the remaining parts of the
Operation section.
To complete a typical operation, the operator does the following:
1. Loosens the knee lock, and adjusts the table height to ensure there is sufficient room to
install the tooling in the quill and the workpiece on the table.
2. Installs correct tooling for the task.
3. Mounts the workpiece securely to the table using a vise or clamps.
4. Selects the appropriate spindle speed for the workpiece and tooling.
5. Selects the direction the spindle will turn, based on the type of cut needed, using the
direction switch.
6. Unlocks the X- and Y-axis table locks, then secures the Z-axis lock.
7. Wears safety glasses or a face shield.
8. Starts the machine.
9. Adjusts the spindle height.
10. For milling operations, uses the X-axis handwheel to move the table left-and-right and
uses the Y-axis handwheel to move the table in-or-out, so the cutter removes material evenly
from the workpiece. For drilling operations, uses the coarse downfeed lever or fine downfeed
handle to lower the tooling into the workpiece, then raises the tooling out of the workpiece.
11. Presses the STOP button to stop the spindle.

4.1 OPERATION INSTRUCTION
Table Controls
A. X-Axis Handwheels: Controls left-right (X-axis) travel of the table.

This mill table has three paths of movement controlled
by the corresponding handwheels or crank
1. Left–right (X-axis)
2. I n–out (Y-axis)
3. Up–down (Z-axis)
The graduated dials are marked in increments
of 0.001", with a full revolution of the handwheel
moving the table 0.125".

Locks
Always keep the table locked in place unless controlled movement is required you’re your
operation. Unexpected table movement during operations could cause the cutter to bind with
the workpiece resulting in damage to the cutter and workpiece, and possible personal injury.

4.2 ADJUSTMENT
The head tilts 90°from left to right.

The turret rotates 360°around the column
1. DISCONECT MILL FROM POWER!
NOTICE: Always lock the turret firmly in place after adjusting the rotation. Unexpected
movement of the head during operations could cause the cutter to bind with the
workpiece causing damage to the cutter and workpiece, and possible personal injury.
2. Loosen the three locking hex nuts on the turret.
3. Manually rotate the head and turret around the column to the left or right and use the turret
rotation scale to determine the amount of rotation.
4. Re-tighten the three locking hex nuts to secure the head and turret in place before
beginning operations.

To select the correct spindle speed (RPM ) for your milling operation, you will need to:
1) Determine the spindle speed needed for your workpiece, and 2) set the speed dial for the
calculated speed.
This mill is designed to use most end mills, drill bits, and face cutters that are 3" in diameter
or less.
Calculating Spindle Speed
1. Use the table in poto to determine the cutting speed or surface feet per minute (SFM)
required for your workpiece material.
2. Measure the diameter of your cutting tool in decimal inches.
3. Use the following formula to calculate the required spindle speed (RPM ) for your
operation:
