Hydraulic Steady Rest Eases Centering Concerns
The extra-large Atling self-centering hydraulic steady rests accommodate workpieces as large as 38" in diameter. The steady rests offer a minimum clamp size of 13.4" (340 mm) and a maximum clamp size of 38" (965 mm). Features include a glass scale for sizing feedback and a linear encoder to measure part diameters to within ±5 µ. The steady rests are designed to maintain the integrity of shaft or bar workpieces that tend to bend or deflect under unstable cutting loads. Built to fit virtually any CNC or conventional lathe, the steady rests deliver a large gripping force in a compact housing, and they fit even where space conditions are extremely limited, the company says.
The challenge holding tight tolerances for its billet RC helicopter engine components drove this company to develop an innovative fifth-axis tombstone device to complete multiple parts on an HMC in one setup.
Holding metal parts with magnets is migrating from surface grinding to broader application in general metalworking processes, especially milling. Advances in magnetic technology are causing many shops to re-evaluate how they hang on to workpieces. Here’s a look at how magnets may be a viable workholding solution for your shop.
