The Jones & Shipman Suprema Easy is a full-CNC universal cylindrical grinding machine with the accuracy and repeatability that has made Jones & Shipman a trusted name in precision grinding shops for decades. This 2007 machine handles both external (OD) and internal (ID) work in a single setup, grinding workpieces up to 300 mm (11.8 in) in diameter and 650 mm (25.6 in) between centers, with a maximum table stroke of 750 mm and infeed programmable down to 0.001 mm. It is equipped with a dual external wheelhead arrangement - a 457 mm (18 in) E-wheelhead driven by a 7.5 kW (10 HP) spindle motor plus a swiveling M-wheelhead - and a dedicated internal grinding spindle turning up to 29,000 RPM for bore work. The continuously variable workhead runs from 1 to 660 RPM with a 5MT live spindle, a 3MT tailstock, and a swiveling table for taper grinding, making it a versatile platform for round, precision components. Set against the older generation of Jones & Shipman manual and hydraulic universal grinders such as the classic 1300 and 1400 series, the Suprema Easy is a substantial leap forward rather than a simple refresh. Where the earlier machines relied on hand-set stops and operator feel, the Suprema Easy adds full CNC control with programmable infeed increments of 0.001 mm, a continuously variable workhead drive, and a swiveling wheelhead, so setups that once demanded a skilled hand now repeat automatically part after part. The result is tighter, more consistent tolerances, faster changeovers between OD and ID work, and less scrap, giving a shop modern CNC grinding precision without the cost of new. For anyone grinding shafts, bores, tapers, or close-tolerance round parts, this is a meaningfully more capable and productive machine ready to drop onto the floor.
