New Hydraulic Chuck from BIG DAISHOWA Promotes Smooth, Stable Cutting

Hoffman Estates, IL – BIG DAISHOWA has introduced a new, high-precision hydraulic chuck for clamping straight shank tools with diameters ¼" to 1¼" and 6mm to 32mm. They are ideal for tools such as drills, reamers, ball mills, end mills and other tools used in processes that require extreme accuracy and a fine surface finish.

"Our customers in the automotive, aerospace and medical fields will love this tool holder for its precision and stability," says Jack Burley, BIG DAISHOWA-Americas president and COO. "What's more, cutting tools can be easily clamped and unclamped with just one wrench."

The hydraulic chucks are pre-balanced to within 15 gr.mm for vibration-free machining at speeds of up to 20,000 RPM. Precision and rigidity are improved due to an integral sleeve construction, dual oil pressure points and a short projection length. They feature runout accuracy guaranteed to less than.00012" (3 microns) at 4xD and repeatability less than .00006" (1.5 microns) - shown to improve the surface finish of workpieces and to extend tool life. They are available for BIG-PLUS (CAT and BT), HSK and CAPTO interfaces.
