SMT SX-4000 HORIZONTAL MACHINING CENTER

Technical Description

The SMT SX-4000 Horizontal Machining Center is a high-performance CNC machine engineered for precision and efficiency in demanding production environments. Featuring dual 15.75" pallets with 0.001" indexing accuracy and a built-in rotary table with 0.001° minimum index, it delivers exceptional repeatability and flexibility. The machine offers X, Y, and Z travels of 22.05", 22.05", and 27.17" respectively, supporting a wide range of part sizes. Its 50 HP BT40 spindle achieves speeds up to 15,000 RPM, providing high torque (184 ft-lbs at 10%ED) and rapid cutting capabilities. The robust double swing arm tool changer manages a 116-tool magazine with a chip-to-chip time of 3 seconds and a tool change time of 1.4 seconds, maximizing uptime. Pallet change time for the two-station APC is 9.0 seconds (JIS), ensuring fast workpiece handling. Axis motors are 7.5 HP digital servo, with maximum thrusts of 4108 lbs on X and 3081 lbs on Y/Z axes. The spindle center to pallet surface ranges from 3.15" to 25.2", and spindle gage line to pallet center from 1.97" to 29.13". Positioning accuracy is ±0.000098" with repeatability of ±0.000059", and pallet positioning repeatability is ±0.00039". The machine is equipped with 6 spindle coolant nozzles, 14 ceiling shower nozzles, and a high-pressure 1,000 PSI coolant system for optimal chip evacuation and tool life.
