SNK NISSIN NK-4 HORIZONTAL MACHINING CENTER

Technical Description

The SNK NISSIN NK-4 is a horizontal machining center engineered for precision turning and milling operations on cylindrical workpieces. Featuring a robust single main spindle with 4,000 RPM capability and 35 HP output, the machine accommodates workpieces up to 12.6" in turning diameter with a maximum 39" turning length, supported by a 10" chuck diameter and 20.87" maximum swing. The turret-based tool carrier provides rapid access to up to 12 turning tools, with simultaneous single-tool cutting capability. The machine operates on two controlled axes: the X-axis delivers 6.89" of travel at a maximum feed rate and rapid traverse of 197 ipm, while the Z-axis provides 39.76" of travel with 197 ipm rapid traverse, enabling efficient longitudinal workpiece positioning and tool advancement. This configuration makes the NK-4 particularly suitable for production runs requiring consistent accuracy and repeatability on medium-sized cylindrical components. The combination of adequate spindle power, moderate tool capacity, and respectable traverse speeds positions this machine for general-purpose turning and milling tasks in job shops and small-to-medium manufacturing environments where flexibility and reliability are prioritized over high-speed production capabilities.
