Cincinnati Machine's (www.cinmach.com) new MEGA5-800 5-axis horizontal machining center uses the MEGA twin ballscrew-driven axes configuration in x-, y-, and z-axes, the MEGA b-axis table and a compact a-axis tilt spindle with 180 degree sweep.
Cincinnati Machine says the new machine has been optimized for titanium machining to provide 50 to 100 percent increase in throughput compared to conventional processes. Optimization includes machine dynamics, tooling, coolant delivery, chip handling and raw material characteristics.
The MEGA5 offers 1425 mm (56.10 in.) of x-axis travel, 1325 mm (52.17 in.) of y-axis travel, and 1265 mm (49.80 in.) of z-axis travel.
Part sizes up to 1300 mm (51.18 in.) diameter and 2000 mm (78.74 in.) high, weighing 2200kg (4840 lbs.) can be accommodated. The machine has a feed rate of 60 m/min (2,362 ipm) and an acceleration/deceleration rate of 1G (386 in/s)(9.8 m/s). Several spindle packages are available including:
An XT spindle configuration that is intended for hard metal applications and available with a geared spindle. This provides providing a base speed of 375 rpm and a maximum speed of 6,000 rpm. Duty rated at 45 kW (60 Hp)/1,146 Nm (845 ftlb) and continuous rated at 37 kW (50 Hp)/942 Nm (695 ft-lb), it is offered in either HSK 100A or ANSI 50 (ISO 7388.1) versions.
An AP spindle package that is intended for aluminum applications, and offers a choice of two high-speed spindles. On high-speed spindle is rated for continuous operation at 50 kW (67 Hp) and the other is rated at 30 kW (40 Hp). Both spindles feature HSK63A tooling interface and are capable of 24,000 rpm operation. The company said the a-axis tilt spindle used on the MEGA5 machine is adapted and refined from the spindle used on its MAGNUM H5-1000 that was introduced in 1999.
