The聽SR 200 BB (Big Bore) high-performance multi-tasking turning center from Hardinge offers users a combination of performance features that include speed, power, accuracy and durability. This heavy-duty turning center features a Hardinge Sure-Grip lever type 250mm (10") three-jaw chuck as standard equipment. The SR 200 BB can be configured with many multi-tasking functions including, livetooling, Y-axis, C-axis and sub-spindle, needed to machine today's complex small to medium sized parts complete in a single set-up, the company says
The turning center is said to be a聽high-performance "chuck and bar" machine that will cut the tough materials and handle deep interrupted cuts while maintaining overall part accuracy. The machine features聽vibration damping that is accomplished through the use of heavyduty linear roller guides mounted to a聽reinforced cast-iron base. The platform allows the user to handle work virtually vibration free while reducing costs of tooling by as much as 33 percent.
SR 200 BB work capacities are: maximum swing over way covers聽is聽22.44" (519.2mm); chuck size (standard Hardinge Sure-Grip chuck) is 10" (250mm); maximum bar capacity is 3.14" (79.7mm); maximum machining diameter is 12.15" (308.6mm); and maximum machining length with tailstock and 10" chuck聽 is 17.2" (436.9mm).
SR 200 BB spindle specifications聽 include a maximum speed of 4000-rpm, a maximum power rating聽of 30-hp (26-kW), torque at base speed (505 rpm)聽is聽306 foot pounds (414.8Nm) and the spindle nose is聽A2-8
Key attributes of the Hardinge SR-Series machines include a. Hardinge/GE Fanuc i-Series SR control unit with high-speed milling capability and multi-axis functionality,聽Fanuc manual guide conversational programming system. hard turning and hard milling capability,聽Harcrete-reinforced cast-iron base for superior damping, improved tool life "hard turning" capability up to 67 HRc,聽exclusive Eppinger top plate option designed for high accuracy, zero clearance tool location, repeatability and robust live tooling system and a vast array of聽 Hardinge workholding systems.
