SHARP 1660 HORIZONTAL MACHINING CENTER

The SHARP 1660 is a compact horizontal machining center engineered for precision turning and milling operations on medium-sized workpieces. Featuring a single main spindle with a 7.000" chuck diameter and 16.000" maximum swing, the machine accommodates workpieces up to 8.750" in turning diameter and 60.000" in length, making it suitable for aerospace, automotive, and general manufacturing applications. The spindle delivers 2,000 RPM with 7.50 HP output, providing adequate torque for heavy roughing passes and rigid cutting operations. The machine utilizes a slide-type primary tool carrier, enabling single-tool cutting operations with controlled tool engagement. With two programmable axes and 60.000" of Z-axis travel, the SHARP 1660 allows for flexible workpiece positioning and extended part lengths. The configuration supports conventional turning and facing operations while maintaining rigidity necessary for dimensional accuracy. This configuration contrasts with multi-spindle designs like the Komatsu KH440, which offers simultaneous four-spindle machining for high-volume production, or high-speed units like the Makino a51nx operating at 14,000 RPM. The SHARP 1660's lower spindle speed and higher torque characteristics prioritize precision and surface finish over production speed, making it ideal for custom job shop work requiring versatility and accuracy on larger diameter components rather than high-volume manufacturing scenarios.
