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.
Coolant Port
2 Coolant ports on the nose of the tool holder direct coolants onto the cutting tool and workpiece to flush out chips and maintain optimal cutting tool performance. Coolant port can be sealed with the included stop screw to drive coolant to the center bore for coolant thru cutting tools. Stop screw needs to be completely threaded in to sit flush with the nose. Coolant port thread size is M4 x 0.70 with 5mm Length.
