KNUTH SINUS 400/1000 HORIZONTAL MACHINING CENTER

The KNUTH SINUS 400/1000 is a horizontal machining center engineered for heavy-duty production work on large components. Featuring a single main spindle with dual RPM configurations of 1,600 rpm and 12.10 horsepower each, this machine delivers substantial torque for machining ferrous materials and demanding applications requiring sustained cutting forces. The spindle accommodates workpieces up to 30.000 inches in diameter with a maximum turning length of 39.000 inches, making it suitable for mid-to-large part production. The machine's two simultaneous cutting tool capability enables efficient multi-operation sequences, reducing cycle times and improving throughput for complex parts requiring multiple machining stages. With a Z-axis travel of 29.000 inches, the vertical envelope provides adequate clearance for varied workpiece geometries and tool lengths. The 400/1000 designation references the pallet size configuration, typical of industrial-grade horizontal machining centers designed for high-volume manufacturing environments. This machine class emphasizes rigidity and precision over high-speed spindle performance, making it ideal for production runs involving heavy interrupted cuts and rigid part clamping requirements. The dual-tool configuration combined with substantial spindle power positions this machine for applications such as casting machining, forging finishing, and large structural component production where material removal rate and consistent accuracy take priority over rapid spindle speeds.
