This is the best tool holder value in the industry! Proven performance on Haas, Fadal, Mazak, Mori Seiki, Kitamura, Hurco, and many others. Tool holder is balanced to G2.5 20,000 RPM on a HAIMER Tool Dynamic Balancing System from Germany. Balanced tool holder minimizes the centrifugal forces which minimize the stress on spindle bearing, minimize vibrati on and maximize the cutting tool's life cycle a nd greatly improve surface finish.
Unique design feature in the extension nose to minimize the off-balance nature of CAT 40 taper specification. On the side of flange where a half spherical hole is located, a flat is cut into the cylinder nose to compensate the weight of the metal chips lost from forming this spherical hole.
And when the holder is placed into the Haimer balance machine, less holes would need to be drilled in the v groove of the flange to protect the rigidity of the tool holder. Evenly weight distribution will minimize centrifugal force in high speed spinning and thus maximize the holder's ability to hold the cutting tool concentric to spindle rotation. We use SCM420 alloy steel fro m. To la y the foundation and case harden to RC 57-59 with a core of RC 34-39 to provide good core strength and maximize wear life. The core creates a dampening effect which reduces vibration in high speed milling to improve surface finish.All critical surface are precision ground. Internal bore concentricity is less th. From taper to end mill pocket. Flange and V-groove are precision ground to ensure reliable tool change. The AT3 or better taper accuracy ensures 80% or better taper contact with spindle and using Stotz Air/Electronic Gaging for inspection on the taper.
All of SHARS CAT/BT/HSK tool holder use. Stotz Air/Electronic Gaging for production and finish inspection. Stotz has been chosen by major aircraft companies as the best and most consistent gaging for tool holder shanks. CAT 40 5/8-11 45 Pull Stud Retention Knob for Haas Kitamura Miyano.
