Steady Rests for Grinding Camshafts, Crankshafts
Kitagawa NorthTech is releasing the fully-retracting KRGU and GHS grinder steady rests.
Kitagawa NorthTech is releasing the fully-retracting KRGU and GHS grinder steady rests, suitable for camshafts, crankshafts and other cylindrical applications where accuracy and repeatability are essential. The two models are designed for turnkey installation.
The KRGU series is specially designed to accommodate the maximum eccentric throw and journal diameter of crankshafts. Custom designs are available to accommodate automated loading, and the systems are available in standard gripping diameters ranging from 2.75" to 7.5" (70 to 190 mm).
The GHS series is for standard and automated grinding applications such as cylindrical grinding, camshaft grinding, camlobe grinding and more. It is available in standard gripping diameters ranging from 0.394" to 4.724" (10 to 120 mm).
Key features of both series include a retractable body using guideways; vertical load functionality; three-point, finely-adjustable centering capability; and modular, regrindable carbide or relappable PCD work pads.
No other process can do what creep-feed grinding can do. Recent tests show even more can be gained by optimizing every element of a creep-feed system.
Roughing and finishing on a single machine, using a single setup, has appeal for most shops. The advantages in time savings and accuracy are obvious. Eliminating the transport of workpieces between machines, as well as the setup for those secondary operations, is a boon for throughput. Critical features that need to maintain dimensional relationships can be much more reliably produced if machined complete in one clamping.
Real-time-responding CNC brings new possibilities to difficult machining applications.
