THESE ARE THE MAIN POINTS TO WATCH OUT FOR!
But read the following pages for more information
•
Handling the mill is at least a two-man job.
•
Lower the center of gravity by hand-cranking the headstock down until the spindle nose
is just clear of the table.
•
Lifting gear – sling, hoist or forklift – must be rated for at least 1000 lb.
•
Working location of the mill must allow: Full left-right travel of the table, and; Access to
the top of the column (for Z-axis leadscrew maintenance).
•
Power requirement is 220V, 60Hz, 15A minimum.
•
Extension cord not recommended; if no alternative, use 12 AWG not longer than 20 ft.
•
Before connecting power for the first time be sure that:
1.
The machine is on a firm footing, adequately secured to bench or stand.
2. No chuck or collet is installed.
3. There are no clamps or locks on moving parts.
4. The speed control knob is set for the lowest speed.
1. Prepare the working location, bench or optional stand.
Highly recommended!
Bolt the bench or stand firmly to
the floor. Check working clearances, Section 2.
2. Remove the packing case from the pallet, Figure 1-1. Un-
bolt the machine from the pallet. Install the largest of the
four handles on the headstock handwheel (top of column
on right). Install the three smaller handles on the X-axis
and Y-axis handwheels.
3. Release the Y and Z axis locks. Check that the mill’s cen-
ter of gravity is as far down and back as possible by crank-
ing both Y and Z handwheels.
4. Pad the underside of the tilt collar with thick cloth.
5. Run a sling under the cloth padding, taking care not to
damage the Z-axis locking handle and the cooling fins on
the electrical box, Figure 1-2.
6. Hook the sling to the hoist. Slowly lift the mill, controlling
any tendency for it to swing as it clears the pallet.
7. Roll the mill into position over the tray, then lower it into
place, Figure 1-3.
8. Secure the mill to the bench or stand. If this is a stand
installation, use the four bolts M12 bolts supplied (the bolt
locations are threaded.) Use lock + plain washers in all
locations.
Setting up the mill
The PM-30MV is shipped in two packing cases, one for the machine and tray (including optional 3-axis DRO), one for the
stand, if ordered. The following procedure makes use of an
engine hoist
, minimum weight rating 1000 lb.
The machine shown in the uncrating and installation photos, Figures 1-1, 1-2 and 1-3, is the PM 25-MVBD. This is smaller and
lighter than the PM-30MV, but otherwise representative.
