Kitagawa NorthTech Inc. introduces its new AS series of grinding steady rests. The AS series expands and completes the company's portfolio of steady rests specifically designed and engineered for grinding applications. The new AS steady rests feature narrow retractable arms for easy automated part loading, as well as many other capabilities for grinding applications.
The narrow retractable arms prevent interference with oil hole journals and provide easy vertical loading of the work piece. Available in standard gripping diameters from 0.39” (10 mm) to 5.59” (142 mm) range, the AS series steady rests can accommodate eccentric throw with body modifications for crank lobe clearance.
Key features and benefits include:
• Steady rest with retractable arms for easy overhead gantry/robot loading
• Suitable for all crankshaft, camshaft and cylindrical grinding applications where vertical load is a requirement
• High accuracy, with three-point finely adjustable centering capability
• Modular regrindable carbide or relappable PCD work rest pads
• Suitable for pass-through grinding capabilities
• Provisions to accommodate attenuating in-process gaging (IPG)
Earlier this year Kitagawa NorthTech launched the new grinding series with the KRGU and GHS. The retracting KRGU grinding steady rests and GHS/VGHS grinding steady rests designed for camshafts, crankshafts and other cylindrical applications. The KRGU is specially designed for crankshaft grinding to accommodate the maximum eccentric throw and journal diameter of crankshafts. The GHS is suitable for all crankshaft, camshaft and cylindrical grinding applications where vertical load is a requirement.

- centering
centering
1. Process of locating the center of a workpiece to be mounted on centers. 2. Process of mounting the workpiece concentric to the machine spindle. See centers.
- clearance
clearance
Space provided behind a tool’s land or relief to prevent rubbing and subsequent premature deterioration of the tool. See land; relief.
- cylindrical grinding
cylindrical grinding
Grinding operation in which the workpiece is rotated around a fixed axis while the grinding wheel is fed into the outside surface in controlled relation to the axis of rotation. The workpiece is usually cylindrical, but it may be tapered or curvilinear in profile. See centerless grinding; grinding.
- grinding
grinding
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- in-process gaging ( in-process inspection)
in-process gaging ( in-process inspection)
Quality-control approach that monitors work in progress, rather than inspecting parts after the run has been completed. May be done manually on a spot-check basis but often involves automatic sensors that provide 100 percent inspection.
- polycrystalline diamond ( PCD)
polycrystalline diamond ( PCD)
Cutting tool material consisting of natural or synthetic diamond crystals bonded together under high pressure at elevated temperatures. PCD is available as a tip brazed to a carbide insert carrier. Used for machining nonferrous alloys and nonmetallic materials at high cutting speeds.
- steady rest
steady rest
Supports long, thin or flexible work being turned on a lathe. Mounts on the bed’s ways and, unlike a follower rest, remains at the point where mounted. See follower rest.
