LIFTING MACHINE

Lifting machine

Figure 1 - Lifting machine

Lifting machine, arrange rope or cable as shown in figure 1, and check to see if the correct balance has been obtained. Then insert pads of soft cloth between the edges of the rope and machine. The net weight of this machine is approx 1100 kgs (2420 lbs). So the rope or cable must be rated at 3000 lbs capacity.

A.) INSPECTION AND CLEANING OF MACHINE

An inspection should be made after arrival of the machine in your plant. Look for possible damage caused by shock or vibration during transportation, also check for any missing parts, standard tools or other equipment.

In shipment, all exposed surfaces of the machine are coated with a antirust liquid. Before moving carriage and cross-slide, lead screw tailstock…etc, these surfaces should be thoroughly cleaned to remove all antirust liquid use a soft brush and solvent. This is very important because it can prevent any dirt or grit which may have accumulated on the antirust liquid from working under the sliding members and causing undue wear.

※CAUTION:
DO NOT USE COMPRESSED AIR TO CLEAN, WHICH WILL REDUCE THE MACHINES LIFE.

B.) FOUNDATION, INSTALLATION, AND LEVELING

A fairly flat foundation and proper installation will provide the machine long-term high accuracy, so supplying a good solid foundation of proper thickness is important. (Generally, a thickness of 300mm (12") is considered to be enough.) The machine has six adjustable feet on the corners of the pedestal base, used for leveling the machine. Place the pads under the feet of pedestal. To adjust, loosen the set screw and raise or lower the foot with a pin wrench so that all six feet rest firmly on the floor. When the adjustment is done, tighten set screws.

C.) ELECTRICAL CONNECTIONS

The CHR-68e TOOLROOM LATHE is shipped completely wired and assembled, Turn Cam Switch "A"(Figure 2) to the "OFF" position, then check motor voltage. Loosen screws "B"(Figure 2), and open the switch case cover, connect the wires from the power source to the terminals (R.S.T), and ground connection is made at the "G"(Figure 3) which is the electric switch case.

Pull out Spindle locking Pin "E" (Figure 4), push "G" (Figure 4) in forward position. The spindle should rotate counterclockwise when viewed from the tailstock end of the machine. If the spindle dose not turn in the correct direction, turn Cam Switch "A" (Figure 2) to "OFF" position. Disconnect electric power source, and interchanges any two leads until the turning direction is correct. When the spindle is rotation correctly, secure switch case cover, turn Cam Switch "A" (Figure 2) to "ON" position.

Carriage Look
Figure 28-Carriage Look

To hold the carriage in a fixed position on the bed use the Carriage Lock Handle "H" (Figure 28). Move the lock handle "H" (Figure 28) clockwise toward the operator, lock the carriage in position. Move the lock handle "H" (Figure 28) counterclockwise away from the operator. To unlock the carriage.

Q.) QUICK-ACTING TOOL POST COMPOUND SLIDE ASSEMBLY

  1. The carriage clutches are made of a friction type material, designed to slip when slide or carriage engages a feed stop. The clutches are a spring-loaded arrangement and can not be adjusted for more pulling power. If clutch slips under a cut, it is a sign of improper tool grinding, dull tool or excessive feed. The friction clutches have sufficient power to handle all work.
  2. When the machine contacts a feed "stop", it is intended for the clutch to slip, To operate clutches as shown in (Figure 29), raise handle "H" (Figure 29) approx. 20degress above horizontal, the clutch will engage, Push down the handle "H" (Figure 29), the clutch will release. When the carriage lead screw is engaged for threading the carriage feed clutch is mechanically interlocked (can not be engaged). This is to prevent machine damage. Adjust clutches as shown in (Figure 29).

It is powered by a AC motor "M" (Figure 31).

  1. The power feed can be operated only when the machine is running. Start the power feed by turning Cam Switch "S" (Figure 32).
  2. The Cam Switch "S" (Figure 32) controls the direction of the power feed.
  3. The carriage Feed Control "N" (Figure 32) controls the rate of feed. When Cam Switch "S" (Figure 33) is placed in "RIGHT" position, the carriage will feed toward the right, the cross slide will feed away from the operator.
  4. When Cam Switch "S" (Figure 32) is placed in "LEFT" position, the carriage will feed toward the left, the cross slide will feed toward operator.
  5. Turn Cam Switch "S" (Figure 32) to "STOP" position, power feed motor is turned off.
  6. The rate of the carriage feed should be pre-selected to suit each particular job, which depend on material, diameter, type of cut, and tooling used.
  7. The numbers on the carriage feed control panel, do not represent either thousandths per revolution or inches per minute. So the operator must test sample pieces for determining the spindle speed and rate of feed which can best suit to the requested surface finish and production rate, then record the proper settings after testing.
  8. Handle I (Figure 30) control power feed Z-axis , Handle J (Figure 30) control power feed X-axis.
