Machining centers minimize vibration

TNP_Awea_ac.gifA new line of bridge-style, high-speed, or box-style machining centers was built with maximum rigidity in mind, incorporating vibration-dampening technology, an extra-large cast bed, a saddle with curved design, and a box-type column with ribbing.

The C frame has seven models in all; five use a box construction and two feature high-speed linear-motion systems. In the box models (BM Series), the bed is hardened and coated with Turcite B for better performance. The BM Series has travels ranging from 25 to 63, 23 to 31, and 21 to 31 inches in the x-, y-, and z-axes, respectively. A 40-taper spindle offers 8000 rpm at 15 hp, and a 50-taper spindle provides 6000 rpm at 20 hp.

The high-speed linear models (BJ Series) have travels of 24 by 20 by 20 or 32 by 20 by 20 inches in the x-, y-, and z-axes. The table is supported by six bearing pads on 35-mm, high-speed guided rails. The standard unit comes with a 40-taper spindle providing 8000 rpm at 10 hp; optional units are available with spindle speeds of 10,000 to 12,000 rpm.

Feedrates range from 945 in/min with rapid cutting feed of almost 400 in/min. These units are built to accommodate up to 4400 lb on the table, and all machines use pretensioned, anchored, large-diameter ballscrews with directly coupled servomotors for increased accuracy. Other standard features include automatic lubrication, a 24-tool drum-type automatic tool changer, air blower, roof enclosure, pedal-operated door, spindle-round flood coolant system, screw-style auger for chip removal with bucket, RS232 interface, and a large electrical cabinet with heat exchanger. CNC options include Mitsubishi or Fanuc.
