According to the company, coordinating two rotary axes and a short linear axis in a twin-turret design helps reduce problems with thermal sta- bility and stiffness resulting from stacked linear axes. The twin-turret design is also said to enable a non-contact, labyrinth seal designed to prevent thermal distortion. The LTT's design minimizes the number of bearing interfaces in the machining loop in order to maximize machine loop stiffness. The machine employs two highly damped hydro- static bearings, and the turrets are bolted together with a solid granite base plate.

FLAP WHEELS ACHIEVE CLOSE TOLERANCES ON CURVED, CONTOURED AREAS Saint- Gobain Abrasives' Nor ton Bla ze R920 ceramic alumina flap wheels are designed to deliver a smooth, consistent finish with a fast, cool, uniform rate of cut in difficult production applications. The wheels are said to be ideal for aggressive grinding and precision finishing, blend- ing, deburring and cleaning operations on such difficult-to-grind materials as super alloys, stain- less steels and cobalt. T h e s h a r p, c e r a m i c a b r a s i ve g r a i n s a n d advanced grinding-aid lubricant provide faster, cooler, burn-free operation, the company says.
