The three machines in the traveling column-design Tongtai SH horizontal machining center series are engineered for compactness and speed. The smallest (4000P) machine is 69″ (1752 mm) wide and has X-Y-Z axis travels of 20″ x 20″ x 20″ (500 mm x 500 mm x 500 mm), while the largest (5000P) machine is 90″ (2286 mm) wide with X-Y-Z axis travels of 28.7″ x 28.7″ x 32.7″ (730 mm x 730 mm x 830 mm).
Double nut pre-loaded 40mm (1.57″)-dia. class 3 ballscrews permit rapid traverse rates of 2,362 ipm (60 m/min) and acceleration/deceleration of up to 1.0G in the X, Y and Z axes. An Absolute Pulse Coder servo system does not require zero return, enabling the machine to be started from any position.
The machines feature 15,000 rpm integral spindles. Via high-low winding switching, they produce 50 hp peak (10 min. rating), 35 hp in high and 25 hp in low, and 184 lb-ft of peak torque at 980 rpm. Spindles accelerate from 0-7,000 rpm in 0.48 seconds and 0-15,000 rpm in 1.9 seconds. Deceleration from 12,000 rpm to stop is 0.8 seconds. The Big Plus dual contact toolholding system is standard, and air/oil mist is used for spindle bearing lubrication.
A high speed full contouring “B” axis provides 0.001˚ precision and 90˚ index time of 0.5 seconds (4000P) and 0.76 seconds (5000P). A hydraulic clamping mechanism assures repeatability.
The standard 60-station automatic tool changer executes changes in 1.4 seconds with average chip to chip time of only 2.6 seconds (4000P) and 3.0 seconds (5000P). A rotary type automatic pallet changer switches pallets in 5.9 – 7.0 seconds
The machines feature rigid Meehanite cast iron frames, and a standard rear discharge chip removal system assures efficient chip removal. A Fanuc OiM-F conversational control is standard with a full complement of high speed machining options for mold detail and electrode machining.
