Horizontal Machining Center for Mass Production Lines The ne SH-4000P horizontal machining center from Tongtai as developed for mass production lines. Sold and serviced by bsolute Machine Tools Inc., the compact SH-4000P has a XY traveling column design here the pallet moves in the Z path. The PC unit, located in front of the machine, is a rotary pallet changer, ex- changing pallets in 5.9 seconds. For pallet rotation in the machin- ing envelope, a contouring B axis indexes the pallet every 0.001 degree and a hydraulic mechanism clamps the pallet in place for repeatability. The B axis is high-speed, ith 90-degree index time of 0.5 second. The SH-4000P features a Meehanite cast iron frame ith a three-point level- ing system. The LHL/LubeUS grease lubrication system is standard for ays and ballscres—no coolant contamination and no aste oil. The 40-mm (1.57") diameter ballscres are Class 3 ith a double nut pre-loaded and pre-tensioned design, enabling a traverse rate of 2,362" per minute. High-speed acceleration reduces non-cut time (XYZ acc/dec of 1.0 G). The BS servo system enables the machine to start any time from any position. rear discharge chip removal system includes a center trough ith high-volume chip ash for efficient removal. dual level caterpil- lar-type conveyor ith a fines separator is suitable for most chips/material. t the center of the machine is an inte- gral spindle ith 15,000 rpm and spindle acceleration from 0-7,000 rpm in 0.48 second and 0-15,000 rpm in 1.9 seconds. Deceleration from 12,000 rpm to stop is only 0.8 second. The spindle, hich sitches indings on the fly, produces 50-hp peak (10 min. rating), 35-hp in high and 25-hp in lo, hile producing 184 foot-pounds of peak torque at 980 rpm. :: bsolute Machine Tools Inc. 800-852-7825 absolutemachine.com BLOG productionmachining.com/blog PRODUCTS productionmachining.com :: 43
