New upgrades for intuitive control and rapid setup
UK grinding machine manufacturer Jones & Shipman has been part of the Hardinge Grinding Group since 2010. The Jones & Shipman product range includes precision cylindrical grinding machines, surface and profile grinding machines and creepfeed grinding machines that serve the toolmaking, mould fabrication, aerospace, automotive and medical sectors.
With the enhanced Suprema 1000 cylindrical grinder, Jones & Shipman is showcasing a concept that meets the demand for high geometric accuracy with quick changeover times in toolmaking as well as in batch and high-volume production. The machine performs complex cylindrical grinding tasks with a simple setup process and is ideal as an entry-level machine.
The numerically controlled, robust, easy-to-operate and highly precise machines are available in three different grinding length capacities (650, 1000 and 1500 mm). Variable grinding disk speed and left and right grinding disks with diameters of up to 450 mm not only ensure a longer service life for the disks but also increase productivity. An optionally available boost to the grinding head performance enables an additional reduction in lead times.
Automatic dressing and grinding cycles allow rapid setup and unmanned production. These “self-teach” grinders will enable inexperienced and experienced operators alike to be immediately more productive. The basis of the user-friendly concept is the J&S “EASY” programming system. The most important innovation is the integration of a Fanuc Power Motion control system with colour touchscreen which offers significantly greater online memory for dressing and grinding programs together with improved response times and therefore contributes to a further reduction in programming and dressing times. Upgrades and extra functions in the “EASY” control program provide additional flexibility and productivity.
