Frictionless Machining Reduces Heat, Chatter
Friction resulting from moving machine components rubbing together can create vibration and heat buildup, both of which can cause problems during machining operations. One machine from NTC America uses hydrostatic components to eliminate sources of friction for high-precision, small-parts machining.

Makino's D500 five-axis VMC is designed for complex part production where part quality is paramount, the company says. The work zone for the center is 500 × 450 mm. The X, Y and Z axes provide strokes up to 550, 1000 and 500 mm respectively. Rotary table axes A and C provide rotational motion of +30 to -120 degrees

The company’s vertical, twin-table machines use dual integrated pallets and are designed for non-stop production performance. One table is accessible for loading or unloading work while the other is safely enclosed in the workzone. The company says this optimizes machine productivity, operator efficiency and safety

Mazak’s HCN 8800-II HMC is built to meet the needs of high productivity for large parts production. It offers a 60-tool storage magazine and a 10,000-rpm, 50-hp integrated spindle/motor generating as much as 900-foot-pounds (1,218-Nm) of torque. Options include 8,000-rpm/50-hp and 16,000-rpm/50-hp spindles. The mac

Horizontal machining centers provide distinct advantages with regard to chip flow, allowing chips to fall away from the machining area for clean cutting conditions and long tool life. Not all shops, however, want or need the pallet-changing capabilities of a production-oriented HMC. For these users, the company has
