The high-performance J350G jig grinder offers application flexibility, accuracy, reliability, and user-friendly operation. 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.
The J350G’s Fanuc 31i-B control has a 15″ 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.
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.
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.
The machine’s 3m2 (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.

2023 New Week XZBRG Product Recommendation:
Full Ceramic Cylindrical Roller Bearings：
Ceramic cylinder roller bearings are made with a single row, two rows, or multi-rows of rolling elements.
the cylindrical roller bearings have line contact between the rollers and raceway, therefore radial load capability is high, making this bearing superior in regards to its ability to withstand heavy loads and impact loads.
They contain cylindrically-shaped roller, which are nevertheless not true cylinders.
Instead, they are crowned or end-relieved to reduce stress concentrations.
This particular geometry results in low friction and allows high-speed applications.
