Product application
Product features
- Dynamically balanced to 20,000RPM at G2.5 by Haimer balancing machine at all location for consistent balance
- Unique design feature in the flange to minimize the off-balance nature of CAT 50 taper specification. On the shoulder under the flange, a side is mill flat to compensate the weight of the metal chips lost from forming the spherical hole in the flange. This design allows the left side and right side of the holder to achieve 50-50 perfect weight distribution in its upright position, like the position inside a machine spindle. Symmetrical design in 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.
- In a generic standard ER collet nut, an internal ring is off-centered so that an ER collet can be easily snapped into it and holds the ER collet in place. To minimize this off-centering, SHARS ER collet nut is optimized to distribute the flat sides' area to off-set the off-center. ER collet nut is also balanced with each holder.
- Manufactured from alloy steel with good core strength and long wear life. Taper shank is case hardened to 56-60 HRC and has a core hardness of 35-40 HRC. The case hardness is designed to give maximum wear life without compromising the 60-62 HRC spindle. The core creates a damping effect from the vibration during the high speed milling, especially in long reach or heavy duty milling application
- Taper ground to AT3 or better accuracy standard for maximum contact with spindle. 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
- All critical surface are precision ground
- Concentricity is less than 0.0001" from taper to end mill pocket
- Each holder comes with a lab certificate on its taper accuracy and runout measurement
- Internal set screw is included and can be used as a stopping pin to prevent end mill or drill from sliding backwards while performing heavy cutting
- Coolant through capability by removing the internal set screw
- The inner holes will be inspected on product line one hundred percent by USA air jet instrument.
