  • Page 16 2. Machine Body Operation: 1. Ram movement (Fig. 17): To move ram in or out, loosen Ram lock levers “A” and move to desired position using handle “B” and retighten levers. To swivel ram, loosen the four bolts “C”, move to desired position and retighten bolts “C”.
  • Page 17 2. Setting handwheel dials to zero (Fig. 18): a. Loosen lock ring “D”. b. Turn dial “E” to zero and tighten lock ring “D”. 3. Locking the table, saddle, and knee: To increase the stability of the mill and maintain a good workpiece finish, all non-feeding surfaces should be locked down.

  • Page 18: Unpacking, Moving, And Floor Space

    7. Unpacking, moving, and floor space: a. Methods of moving machine: Prior to unpacking or removing from skid, the machine should be moved by the use of a forklift or reinforced cable (Fig. 20 & 21). Removal from the skid and any further movement of the machine should be done by the use of a reinforced cable or by the eye bolt located in the top of the ram.
  • Page 20 b. Unpacking: To protect the machine while in transit it is necessary to cover it with a rust proof coating and a crate or plastic wrapping. In the event, there is damage due to moisture, please contact our agent or the transporter. After unpacking, make sure all tools and accessories are intact.

Lock saddle and turn hand crank “F” clockwise to separate bracket “G” from the knee. Unlock saddle and move screw until adjusting tool fits into the space.
  • Page 33 B. X axis backlash adjustment; Move the work table to the center of the saddle. Insert large end of adjusting tool into the left side of the saddle and turn lock nut “J” counter clockwise approximately one turn. Using small end of tool tighten adjusting nut “K”. After adjusting nut “K”, use large end of tool to re-tighten lock nut “J”.
  • Page 34 6. Adjusting Gibs: After a period of time the gibs may become loose or worn and may need to be adjusted to maintain the integrity of the mill. A. Table Gib (Fig. 32): The table gib is located between the saddle seat and the table dovetail.
  • Page 35 B. Saddle Gib (Fig. 33) The saddle gib is located between the left side of the saddle and knee dovetail, and it can be adjusted as follows: Loosen saddle lock “A”. Move saddle to the front of knee. Remove wiper holder “B” on saddle. Clean and lubricate sideways.
  • Page 36 C. Knee Gib (Fig. 34) The knee gib is located between the left side of knee and column dovetail, and it can be adjusted as follows: Loosen knee clamp (Fig. 5, Page 5). Remove wiper holder “Q”. Clean and lubricate sideways. Raise knee to its uppermost position.
  • Page 37 E. Collet Alignment Screw Replacement: First mark the location of nose piece “B” to its position to quill “A”. b. Remove set screw “C” located on nose piece. Remove nose piece by inserting an adjustable spanner in two holes in the bottom of nose piece.

  • Page 38: Maintenance

    10. Maintenance “Maintenance is more important than repair, and repair is better than purchase.” The life of a machine can be greatly reduced if it has been properly maintained and operated. The result will be premature wear, inability to hold tolerance and poor finish on the workpiece.
  • Page 39 11. Notice: 1. Machine Operation: Machine must be installed on a solid base. b. Be sure the machine base and surface have proper contact before tightening anchor bolts. c. Be sure motor voltage conforms to the source voltage and properly grounded. d.
