MACHINE DESCRIPTION
AND INTENDED USE
Applicable Machines: T-42, T-51, and T-65 Lathes
These lathes are numerically controlled machine tools designed to shape cold metal by the appli-
cation of a cutting tool and rotating workpiece capable of performing two or more machining pro-
cesses (e.g. turning, facing, drilling, grooving and boring) at one set-up of a workpiece and
incorporating the following features:
•Select and change tools from a turret.
•Change the position of the turret relative to the spindle clamped workpiece.
•Select and apply spindle speeds and axis feeds.
•Control auxiliary services.
•Tailstock provides added support when machining long parts and reduces part deflec-
tion.
•Optional sub-spindle provides capability of back side tuning.
•Optional live tooling provide milling capabilities.
These lathes are designed to machine non-hazardous metals only.
Non-hazardous materials such as Tools Steels, Aluminum, and Brass may be machined.
DO NOT machine any flammable, explosive, toxic, or radioactive material.
DO NOT machine any material that produces a hazardous residue, dust, or gas.
DO NOT use any flammable, explosive, or toxic cutting fluids.
In all cases, if in doubt about the content of the material that you wish to machine, contact the mate-
rial supplier.

WARNINGS
CHEMICAL WARNING:
Current laws and regulations require that information regarding chemicals used
with this equipment be supplied to you. Refer to the applicable section of the
Material Safety Data Sheets supplied with your machine when handling, storing, or
disposing of chemicals.
BAR FEED WARNING:
Machine should only be used with a bar feed approved by Hardinge Inc.
SPINDLE TOOLING WARNING:
Hardinge HQC (Quick-Change) collets MUST NOT be used in applications where
the spindle is rotating without a bar or workpiece in the collet.
Rotating the spindle without a bar or workpiece in the collet can result in the collet
head being expelled from the spindle.
Failure to comply with this warning can result in serious injury or death.
ENTRAPMENT WARNING:
DO NOT climb into the machine guard! You may become entrapped.
Due to the compact size of the Hardinge lathes and the provision of side access
doors to allow servicing of the machine, it is not necessary to climb into the
machine guard.
In the unlikely event that this warning is ignored and the main access door is
closed, the door will latch shut and cannot be opened from the inside. Another
person must release the door lock. Refer to the Operator's Manual (M-505) for
information on releasing the door lock.
MAIN COOLANT GUARD:
The guards provided with the machine are intended to minimize the risks of
workpiece ejection and not to eliminate them completely.

CHAPTER 1 - INSTALLATION
MACHINE INSTALLATION REQUIREMENTS
T-42, T-51, and T-65 lathes require a substantial foundation. Do not locate the machine near equip-
ment that causes vibration. Poor surface finishes or damage to the control may result from vibration
transmitted to the machine.
FOUNDATION REQUIREMENTS
Refer to Figure 1.1, 1.2, or 1.3 to locate the feet in the machine base. Use the dimensions to size the
machine footprint and locate the concrete pads.
The soil under the pads or floor for the machine must be compacted to a safe bearing capacity of 4
tons per square foot [0.38 MPa].
The pads must be level with each other within ±.13 inch [±3.3 mm] or the floor must be level within
±.13 inch in 5 feet [±3.3 mm in 1524 mm] and be constructed of 3000 psi [207 bars] concrete or better.
Avoid placing the machine over floor expansion joints.
RECOMMENDED 6 inch [152 mm] thick concrete floor as large as the machine footprint.
The machine footprint is the overall dimensions, length and width, of the
machine.
ACCEPTABLE Concrete pads 14 x 14 x 6 inches [356 x 356 x 152 mm] centered under
each of the machine feet.
MINIMUM 4 inch [102 mm] thick concrete floor as large as the machine footprint or
concrete pads 14 x 14 x 4 inches [356 x 356 x 102 mm] centered under
each of the machine feet.
APPROXIMATE WEIGHT
- NOTE -
The machine weight and shipping weight will vary, depending on the configuration
of the machine.

2. Leave the machine on the skid and move it to the installation location.
3. Remove any parts boxes from the skid.
- NOTE -
Retain the M12 screws, washers, lock washers, and hold-down brackets in the
event the machine is to be used with a bar feed system. Refer to page 1-6 for
information on securing the machine to the floor.
4. Remove the M12 screws, washers, and lock washers that secure the hold-down brackets to the
machine.
5. Remove the hold-down brackets from the skid.
6. Thread the adjustable foot, shown in Figures 1.1 through 1.3, all the way up for clearance.
Initially, the machine is supported by the three non-adjustable feet.
- WARNING -
Raise the machine high enough to make certain that the machine feet and sup-
port screws clear the skid.
- NOTE -
There are two lift slots running front to rear under the machine base. Refer to
Figure 1.1, 1.2, or 1.3. Lift the machine slowly to make certain that the fork lift
truck maintains balance.
7. Use a fork lift truck or the rigging to lift the machine from the skid. Lift the machine slowly while
making certain that it remains balanced.
8. Carefully lower the machine into position. The machine will be supported by the three
non-adjustable feet. Rough align the machine.
9. Thread the adjustable foot down until it makes contact with the floor.
10. Tighten the adjustable foot an additional one-sixteenth turn.
11. Secure the adjustable foot lock nut up against the machine base.
M-507C 1-5

SECURING THE MACHINE TO THE FLOOR
- CAUTION -
The hold-down brackets MUST be installed if the machine is to be used with a bar
feed system.
- NOTE -
The lag screws, flat washers, and expansion shields used to secure the hold-down
brackets to the floor are provided with the machine
1. Align the hold-brackets with the mounting holes on the machine base. Refer to Figure 1.4.
2. Mark two drilling locations on the floor for each bracket.
