First milling machine parts manual

GEAR DRIVEN LONGITUDIANL FEED

• The table is driven by steel gears box with 12 speeds change and rapid feed for positioning of work piece.

• Ni-Cr alloy steel spindles are supported by three super precision preloaded angular contact ball bearings. The spindle drive can be operated as manual feed, micro feed and automatic feed. It is idea for precision millimg and drilling operations.

GEAR DRIVEN HORIZONTAL SPINDLE

• All gears that drive the horizontal spindle system are made of alloy steel, precision ground and hardened for heavy cutting and quiet operation. The automatic lub. system keeps the gears lubricated at all times. The 5HP motor drive with 6 speed chenges offers high torque cutting in wide range of speeds.

EXCLUSIVE VARI-DISC DESIGN

• To ensure smooth operation under hugh speed and to eliminate noise and vibration in the vertical head, the vari-disc is treated with HD polymer at the inside diameter using a patented process. (CNS
