Jones & Shipman Hardinge / AMB High-precision metal cutting and grinding technology on show

The display of machines at the Jones & Shipman Hardinge booth at AMB include the Kellenberger 100 platform concept cylindrical grinding machine and two Hardinge Super Precision turning and turn/grinding CNC centres.

Among the machining centres at the Jones & Shipman Hardinge's booth at AMB in Hall 5, Booth B80, is the Kellenberger 100, a high-performance, cost-effective, cylindrical precision grinder. Its flexible modular design delivers a range of configuration alternatives for diverse grinding applications. Also, the modular construction is designed to reduce machine build time yet accommodate “standard” options with a good price/performance ratio for the end user. Distinguishing features of the Kellenberger 100 are its collision-free, compact wheelhead solution, performance parameters and service-friendly machine concept. The Kellenberger 100 has the latest Fanuc 31i CNC controls with 19" touchscreen guidance system on an operator-friendly panel.

The Hardinge Super Precision turning and turn/grinding machines are said to have tight tolerances when manufacturing hard-to-manufacture parts, as in the latest Hardinge T-Series CNC lathes, while achieving high precision and capability. At AMB, the two Hardinge machines in operation will be the Quest GT 27 SP turn/grind centre and the T42 SP turning centre.

The Hardinge Quest GT 27 SP is a combined turning and grinding centre, designed for high precision manufacturing of complex parts, featuring a 10hp, 8,000-rpm main spindle and a 27-mm bar capacity. It can also be equipped with a “Big-Bore” spindle to handle up to 42-mm bar capacities.

The other Hardinge machine on show, the Hardinge T42 SP, is suited for productive and reliable manufacturing. It delivers precision and accuracy for 2-axis, high-precision machining or complex multi-tasking operations that require precision, delicate part handling and complete parts made in a single setup. It features a 15-hp, 6,000-rpm A2-5 collet ready spindle with a 42-mm bar capacity and a 16-station turret, which offers a half station index for up to 32 tools. In production, a high level of precision/part surface finish is maintained at .15 micron, with part roundness at .25 micron and continuous part accuracy within .3 micron. The overall axis repeatability is .76 micron, the company notes.
