PRODUCT SPOTLIGHT
Mirror Finish
- To achieve AT3 or better taper contact as an industry standard, our taper surface are precision ground on Shigiya CNC grinder from Japan. We are not satisfied with just meeting the industry standard, the surface roughness on the taper is maintained to mirror finish.
AT3 or Better
- Taper ground to AT3 or better ensures 80% or more contact with spindle to reduce harmonics and improve runout tolerance
Pilot Contact
- Inside bore are precision turned to engage a better contact with retention knob's pilot to increase rigidity
Taper End Face
- Precision turning surface finish provide perpendicular contact with the flange of retention knob to increase rigidity
Pre-Balance Design
-
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.
Dynamic Balancing
-
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 vibration and maximize the cutting tool's life cycle and greatly improve surface finish.
- TIR from taper to end mill pocket is less than 0.0001"
- Each holder comes with a lab certificate on its balancing data
- Flange and V-groove are precision ground to ensure reliable tool change
- Spindle Thru coolant capability
