BED, COLUMN, AND SADDLE:
The bed is a rigid one-piece casting with heavy ribbing to prevent deformation during heavy cutting. Fine grain Meehanite cast iron is used for its excellent dampening characteristics. Extra wide outer boxways provide excellent support for the saddle, regardless of the load distribution on the table. The table is fully supported by the saddle in all positions. There is no table overhang. The rigid box type column casting is heavily ribbed to prevent twisting or distortion.
SPINDLE, HEADSTOCK, AND COLUMN
The high speed, 6,000 RPM, 50 taper spindle is a true cartridge type unit supported by precision class bearings that are permanently grease lubricated. The spindle is driven by a high torque 25 HP (30 min.) A.C. motor delivering an impressive 384 ft/lbs. (521 nm). Power is transferred through a heavy-duty two-speed planetary gear driven ZF gearbox, delivering outstanding heavy cutting performance. Promotes thermal stability and eliminates vibration. An encoder is attached to the spindle to allow rigid tapping.
Balanced 6,000 RPM Spindle with spindle oil cooler 6000 BTU for High Speed Machining.
Hardened and Ground class C3 precision double-nut ballscrews (Ø40 mm) are pre-tensioned to minimize backlash, provide high precision movement, and reduce heat deformation on all axes.
Precision scraping on both bonded Turcite-B and cast iron surfaces helps to reduce wearing out,
maintaining operation accuracy. Hardened and ground slideways give an extra 40% wear resistance.
Wide Box ways are used for unsurpassed long-term rigidity and accuracy. Each guideway is induction hardened and precision ground. Turcite is bonded to the mating way surfaces and then hand scraped to ensure perfect fit and tolerances. The Turcite resin with forced way lubrication provides a low friction surface and virtually eliminates guideway wear. All guideways are fully protected from chips and damage.
OIL JACKET SPINDLE CHILLER (STANDARD)
Machine accuracy is maintained by using a refrigeration system that circulates cooled oil around the spindle reducing the thermal effects of any heat generated.
