4.2.2 Table, Saddle, Knee and Column Gib Locks
The table clamps are located on the front of the saddle. Rotate them clockwise until
snug--overtightening is not necessary.
The saddle clamp is located on the left side of the saddle. Rotate clockwise to clamp the
table until snug--overtightening is not necessary.
The knee clamps are located on the left side of the knee for the K2 and K3 mills,
and on the right side for the K4.
The column clamps are on the right side of the column on the DPMEX2.
CAUTION!
Do not run ProtoTRAK EMX program unless the table and saddle clamps are free.
4.2.3 Raising/Lowering the Knee
The knee is raised and lowered using the hand crank located on the left front of the
knee. Clockwise rotation moves the knee up, while counterclockwise rotation moves the
knee down.
Be sure the knee is unclamped before raising or lowering.
4.2.4 Spindle Brake
The mechanical spindle break is activated pulling it down, or pushing it up. When the
lever arm is in the horizontal position, the brake is off.
CAUTION!
Be certain that the spindle brake is released before starting the motor. Never attempt to activate
the spindle brake when the motor is on.
4.2.5 Draw Bar
The draw bar holds the R8 or #40 NST tool holders into the spindle taper. The bar has a
5/8-11 right hand thread and should be tightened with a 23mm wrench from the top of
the head. When tightening, it is necessary to activate the spindle brake (See 4.2.4
above). If the tool holder does not release from the spindle, lightly tap on the top of the
bar to dislodge the tool.
4.2.6 High-Low-Neutral Level
The spindle RPM range selection is made through the High-Low-Neutral Lever.
