According to the manufacturer, the compact, dual-spindle MGX is a high-productivity precision tool grinder for tools up to ½” diameter shank and lengths up to 6”, including burrs and router bits. The tool features an integrated robotic loader, tool change times of less than five seconds, as well as pallet loading with up to 280 tools per pallet, which permits extended unmanned operation. The company says the tool features nine machines axes: five traditional rotary and linear axes and four soft axes. Using the power of the CNC, the four soft axes are said to provide the versatility of a nine-axis machine with the mechanical simplicity of a five-axis machine. The machine's offset dual spindle design can be used to provide up to six grinding wheels in a single cycle with minimal interference or repositioning. Spindles can be set up with high speed and low speed wheel packs. Each spindle can deliver up to 11 hp at up to 10,000 rpm for high stock removal rates. A 20,000-rpm spindle is optional for polishing or grinding with small wheels. The company’s precision collet assembly and precision adjustable pop-up steady means that runout as low as 0.000008" to 0.000016" (two to four microns) in a production environment is typical, and setup times are as low as 10 minutes. Collets are easy to change while maintaining tolerances. According to the manufacturer, the tool can be programmed to produce any combination of tools from a single pallet of blanks, making it efficient even in small batch runs. Because it is a Windows NT-based system, its control system is said to make it easy for operators to use the company’s ToolRoom software. It permits new part development simply by entering the parameters of the new tool into the CNC, avoiding trial and error machining of new tools.
