Mazak’s Horizontal Center Nexus (HCN) 4000-III horizontal machining centre has undergone changes to enhance performance and help customers improve productivity.
Key performance enhancements include those that shorten part cycle times and allow the HCN 4000-III to handle a wider variety of part sizes and more parts per setup. Faster rapid traverse speeds and acceleration rates, shorter chip-to-chip times and increased tool size capability are what contribute to reductions in cycle times. While, greater part size versatility and parts per fixture result from the HCN 4000-III’s expanded Y axis travel/stroke, as well as a higher allowable thrust in its Z axis.
Rapid traverse speed on the HCN 4000-III is now 2,362 ipm (60 m/min), and machine acceleration rate went from 0.8G to a faster 1G. Mazak also shortened the machine’s spindle acceleration speed to only 1.3 seconds for its standard 12,000 rpm spindle and to 1.5 seconds for an optional 18,000 rpm spindle.
For fast, efficient and versatile machining of a wide variety of materials from steels to nonferrous metals, Mazak also offers 14,000 rpm and 30,000 rpm spindle options for the HCN 4000-II. The four available integral motor spindle types−standard, high torque, semi-high speed or high-speed–allow users to match spindle performance to their specific machining requirements with the proper speeds and power.
The standard 40-taper 12,000-rpm spindle provides power and speed for general machining applications, while the high-torque heavy-duty 40-taper 14,000-rpm version generates 88 ft-lbs of torque at a continuous rating to a maximum of 223 ft-lbs to increase metal removal rates for hard to machine materials. With maximum speeds of 18,000 rpm and 30,000 rpm, the 40-taper semi high-speed and HSK high-speed versions allow for faster machining and superior surface finishes when cutting aluminum and other nonferrous workpieces.
