APPLICATIONS
SPR’s precision linear mills are versale, ecient, and designed with the end user in mind. The mills are
designed with ball screws and rails in all three axis, X-Y-Z, to replace older dove tail models. Mulple
spindle posions allow for a greater range of milling adjustments whether it is horizontal, vercal and/or
angular. This allows the machine to produce CNC quality work in eld/shop condions depending on the
job scope.
When you receive the Linear Mill:
The Linear Mill is generally shipped in one crate. Inspect the machine for shipping damage. Verify
that all of the parts listed below, or on the Bill of Materials, are present. If any parts are missing, or
if you have quesons regarding the Linear Mill, please contact a Superior Plant Rentals or SPR York
locaon nearest you immediately.

TOOL REQUIREMENTS
• Dial gauge and magnec dial gauge stand
• Imperial Hex Keys
• 15/16 Box Wrench
• Welder
• CAT40 Taper Insert
• CAT40 Cung Head
LINEAR MILL SETUP
1. Carefully remove all components from crate, liing heavy items with a crane using the eye-bolts
provided.
Li X-BASE using all four EYE-BOLTS keeping X-BASE in a horizontal posion (Figure 1).
DO NOT allow liing straps to push down on BALL-SCREW (Figure 1).
2. Li X-BASE by the four provided LIFTING HOIST RINGS with WELD PLATE aached with 5/8X1.75in CAP-
SCREWS (Figure 1) and set X-BASE into nal milling posion.
TOOL REQUIREMENTS AND SETUP
FIGURE 1

PAGE 7 OF 16
3. Remove ARM-CLAMPS from X-CARRIAGE. Using the provided EYE-BOLTS, place Y-ARM on X-CARRIAGE
and reaach the ARM-CLAMPS, ensuring that the end of Y-ARM is ush or overhanging with the edge
of X-CARRIAGE. Tighten the ½-13X1 SOCKET HEAD CAP SCREWS on both ARM-CLAMPS ( Figure 2).
Do not extend Y-ARM inwards past the edge of the X-CARRIAGE to obtain more travel.
4. Take measurements with a scale or tape measure to ensure the base mill is straight or parallel to the
pad or surface to be machined.
5. Place a series of sch welds about 1” long around the outside of the boom of the weld plate to
securely aach the mill and weld plate into posion.
6. Loosen all 5/8-11 SOCKET HEAD CAP SCREWS in WELD-PLATE to allow adequate room for levelling.
Do not weld directly on any parts of the machine other than the WELD-PLATES.
While welding, cover/protect machine to prevent weld splaer from damaging rails, runner-blocks,
ball-screw and other crical components.

7. There are two dierent methods that can be used to level to mill for machining. One is to use an
indicator as described below, and the other is to use either a machinist level or transit level to level the
rails to the world.
8. Place a DIAL-INDICATOR on the Y-CARRIAGE (Figure 3) and level the machine by adjusng the JACKING
SCREWS while running the DIAL-INDICATOR along both X and Y-axis.
9. Once level, aach the dial indicator next to one set of JACKING SCREWS with the dial indicator
referencing the ground (Figure 4).
10. Carefully ghten the 5/8-11 CAP-SCREWS and the JACKING-SCREWS ensuring that the DIAL-INDICATOR
doesn’t change the posion. Repeat for the other sets of JACKING SCREWS.
11. Lightly “Finger Tighten” JACKING-SCREWS into the remaining 8 posions and repeat the ghtening
procedure of both JACKING-SCREWS and 5/8-11 CAP-SCREWS using the DIAL-INDICATOR at each new
posion (Figure 4) to maintain level posion.
Tightening the screws without the DIAL-INDICATOR can cause the X-BASE to bend, reducing atness
and potenally damaging the machine.

12. Align the top reference surface of the Z-ASSEMBLY onto the Y-CARRIAGE and align edges prior to
inserng and ghtening the 1/4-20 SOCKET HEAD CAP SCREWS on either side of the Z-ASSEMBLY
(Figure 5).

13. Note: There are dierent opons for the SPINDLE posion depending on desired height and if milling
downwards, upwards or sideways. Addionally, the BELT-HOUSING can be dissembled and rotated
to the le, right or center if clearance is required. This will require loosening and removal of ming
pulleys.
14. Place the user-provided CAT40 TAPER inside SPINDLE and draw up by ghtening the DRAWBOLT. Aach
the user-provided TOOL-HEAD to CAT40 TAPER.
FIGURE 6

7. To feed the Y-Axis or Z-Axis, loosen RAIL-CLAMPS and turn HAND-WHEEL.
NOTE: Z-AXIS will drop when loosening RAIL-CLAMPS
8. To power feed the X-Axis, ensure CLUTCH is engaged by snapping it inwards towards the GEAR-BOX.
9. Lock out all the RAIL-CLAMPS in non-feeding axes when cung material.
Vibraons from cuts which are too deep or too fast can cause the RAIL-CLAMPS to slip.
1. The Linear Mill is similar in operaon to any 3-Axis Milling Machine.
2. Before operang ensure all mounng fasteners are secure.
3. Ensure all pneumac lines are connected correctly.
4. Start-up milling spindle away from job to check for correct rotaon.
5. Adjust speed and feed to suit tooling and material.
6. To feed the X-Axis manually, loosen both X-RAIL-CLAMPS (Figure 6) and pull the CLUTCH outwards to
disengage from the GEAR-BOX (Figure 7).

TIPS FOR BEST RESULTS
1. Slower feed on cuts will produce less vibraons and a beer surface nish.
2. Convenonal milling will produce less vibraons and a beer surface nish.
3. Narrower cuts will produce beer atness by minimizing misalignment of cuer tool
4. It is recommended that with the pneumac mill, a max depth of cut of 0.020” or less will achieve the
best results.
5. Posioning the Linear Mill as close as possible to the material to be cut will produce beer surface
nish.
6. Hand-wheels can be placed on either end of the Y and Z-axis feeds.
7. Clear chips while machining (Do Not use your hands to clear chips)

MAINTENANCE
Ensure during setup and operaon that the X-BASE
(Figure 1) is in an unstressed state. Failure to do so
may result in damage to the machine components
and undesired results to the work.
Timing belts will stretch over me and should be
checked occasionally to ensure proper tension is
maintained.
Ensure all machined surfaces are cleaned and lightly
lubricated as assembled. Wipe o excess oil as oil
will aract dirt and debris.
DO NOT weld directly to any part of the
machine other than the WELD-PLATE
(Figure 1).
While welding, cover exposed parts of the machine
to prevent damage from weld splaer.
DO NOT use air to clear debris as debris
may be forced into running components
resulng in damage.
When not in use, machine should be stored in its
crate and kept in a clean and dry environment.
TROUBLESHOOTING
SPINDLE NOT ROTATING
• Check pneumac hose connecons.
• Check air source
X-AXIS NOT FEEDING
• Check clutch is engaged
• Check shear pin hasn’t sheared
• Check pneumac hose connecon
• Check air source
MACHINE DOESN’T HOLD POSITION
• Tighten RAIL-CLAMPS
• Reduce cut depth, cut width or feed speed to
reduce vibraons
MACHINE AXIS HARD TO MOVE
• Disengage RAIL-CLAMPS
