MMS AUGUST 2018 140 IMTS 2018 Milling Machines ULTRA SPEED UH High-Speed Mill Unsurpassed speed & accuracy IMTS Booth #134802, EAST - Sept. 10th-15th, 2018 Superior stability Jig Grinding & Hole Drilling Functions available (847) 310-9000 HMC Built for Mass Production The SH-5000P HMC from Tongtai, displayed in the booth of Absolute Machine Tools, is designed for mass pro- duction. Measuring 90" wide, the HMC has a 35 percent smaller footprint than the previous model. The machine features an XY traveling-column design. The pallet moves in Z. The rotary-type automatic pallet changer, located in front of the machine, is designed for accessibility and exchanges pallets in seven seconds. For pallet rotation in the machining envelope, a full contour- ing B axis indexes the pallet every 0.001 degree and a hydraulic clamping mechanism clamps the pallet in place. The B axis has a 90-degree index time of 0.76 seconds. The HMC features a Meehanite cast iron frame with a three-point leveling system. An LHL/LubeUSA grease lubrication system lubricates ways and ballscrews and reduces coolant contamination and waste oil. The 40-mm-diameter (1.57") ballscrews are class-three with a double-nut, pre-loaded and pre-tensioned design, facilitating a traverse rate of 2,362 ipm. The absolute pulse coder servo system does not require zero return. The machine can be started at any time from any position. A rear discharge chip removal system includes a center trough design with high-volume chip wash. A dual-level, caterpillar-type conveyor with fines separator suits most types of material. An integral spindle capable of speeds as high as 15,000 rpm can accelerate from 0 to 7,000 in 0.48 sec- onds and 0 to 15,000 rpm in 1.9 seconds. Deceleration from 12,000 rpm to 0 requires 0.8 seconds. The spindle produces 50 hp peak (10 min. rating), 35 hp in high and 25 hp in low while producing 184 ft./lbs of peak torque at only 980 rpm. | Absolute Machine Tools Inc. | South, Level 3, Booth 338536
