• 3 Axis conversational CNC, semi-automatic or manual operations use ballscrews and programmable controls for table movement
• High precision spindle is supported by four pieces of class 7 (P4) super precision angular contact ball bearings that are permanently lubricated. The new spindle design includes circulation grooves on spindle with options for air and oil cooling
• Air-counter balance system on spindle housing to reduce load burden on machine structure
• Headstock elevation accuracy is adjusted by gibs and designed with counterweight balance device to ensure the micro downfeed accuracy
• Precision C2 grade ballscrews on longitudinal feed, cross feed and down feed axes directly mounted via coupling to the Mitsubishi® AC servo motors
• The base and saddle guideway systems use heavy duty needle roller bearings running on slide rails. The one-piece base casting has been stress relieved and finite element analyzed
• Hardened and ground table guideway system with precision heavy duty needle roller bearings provide precise linear movement during rapid traverse
• Recirculating forced lubrication system on all guideways
• Shown model B1640II with optional accessories
• Voltage requires 220V/3 Phase/60 Hz.
• Microsoft® WinCE Platform, 3 axis PC based control
• 10.4" Color TFT screen
• Simple graphic conversational controller with preview function
• Various built-in factory-programmed canned cycles
• Conversational canned cycles for surface, crisscross, plunge and multi-slot grinding
• Powerful graphic program input function, available for grinding and dressing
• Easy to operate and can combine grinding cycle, wheel dressing and auto compensation without using a CNC program
• Wheel dressing can be executed during grinding cycle
• Simulate grinding path and dressing cycles by turning MPG handwheel
• Grind multi-slots with different pitch and depth
• Conversational and G-code programs can be saved in hard drive or floppy disk
• FANUC® CNC Program compatible
• Patented longitudinal stroke adjustment from screen
• Ethernet/intranet connectivity
