The machine’s grinding infeed stroke is the largest available among competing machines, with a U-axis range of -3mm to +50mm relative to the spindle center. This provides the flexibility to grind small and large diameter holes, as well as multiple features, using a single wheel in a continuous, automatic mode.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">The J350G’s Fanuc 31i-B control has a 15&quot; touch panel LCD screen and is preloaded with G-MAPS conversational-style programming software. The control also permits easy manual programming via graphic icons, data entry, or conventional methods.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">To maximize accuracy, the X- and Y-axis of J350G are hand scraped and incorporate needle roller bearings. Left and right slideways are V-F flat shaped, and the Y-axis (spindle head motion) is V-V shaped to maximize positioning accuracy. The machine bed consists of a thick, highly rigid casting supported by three level points, assuring consistent perpendicularity and parallelism. Built-in, custom-designed Heidenhain scales contribute to ±0.0007mm accuracy on the X-, Y- and Z-axis.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">Table longitudinal travel (X-axis) is 500mm, transverse travel (Y-axis) is 300mm, and quill travel (Z-axis) is 100mm. Maximum distance from the table surface to the grinding spindle nose is 450mm. The machine’s work surface is 700mm x 350mm and permissible table load is 300kg. Table and saddle maximum rapid feed rates are 2,000mm/min and grinding feed rates are variable from 0.1mm/min to 2,000mm/min. The standard high-frequency spindle motor operates from 9,000rpm to 45,000rpm. A variety of spindle motor options include an air-turbine motor with 75,000rpm capability.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">The machine’s 3m2&nbsp;(2,220mm x 2,610mm) footprint is 50% smaller than that of the previous model, maximizing floor space efficiency. A standard total enclosure machine cover permits easy operator access while fully addressing safety and environmental concerns.</span></p><p><br/></p>
