NEW 16"x40" CNC SURFACE GRINDER

The Smart-1640 is a conversational and G-code language CNC grinder with easy to use controls. The machine has a PC-based control with a 15" color monitor, RS232 interface for uploading and downloading CNC programs, 3.5 floppy disk drive for CAD/CAM files, soft key type alpha-numeric keyboard and can be switched to manual, semi-automatic, fully automatic or CNC operation. The machine control uses conversational language with data input done in question-and-answer format. The screen displays profile and contour grinding options as well as 4 standard dressing modes. Canned cycles include slicing, plunge, criss-cross and step with optional hydraulic creep feed. There is a "macro zone" which allows the operator to create his own programs. The automatic wheel dressing and compensation can be done during machining or at end of cycle. The wheel dressing program is also in conversational format and offers a graphic display of the wheel shape to confirm accuracy. The cartridge type spindle has 4 class 7 (P4) high precision angular contact ball bearings. Labyrinth type seals are used in the front and rear of the spindle cartridge. The new spindle design is aircooled and is available with optional spindle chiller. The Y axis uses box ways which are Turcite-B coated and then precisely hand-scraped while the X and Z axes use needle roller bearings running on heavy duty slide rails. A counter balance in the spindle vertical drive provides greater downfeeding accuracy. The downfeed and crossfeed axis use class C3 hardened and ground ballscrews, driven by Mitsubishi AC servo motors which permits more precise positioning. A cog belt ensures no-slip operation under all machining conditions. The Y and Z axes have electronic handwheel and MPG, respectively, for manual axis operation. The machine utilizes a fully automatic lubrication system which continuously feeds oil to the column. The 16"x 40" table is fully supported underneath, preventing table overhangs. Models are available with 2 axes (hydraulic driven) and 3 axes (ballscrew type) CNC controls.
