ISCAR-ETM is introducing the new MAXIN power chuck.
With this new tool, only a small tightening torque compresses the frontal nose, developing an extremely high tool gripping force.
It is designed for rough and finish milling applications where high
torque transmission, maximum accuracy, compactness and easy operation are required.
The high gripping force achieved by the MAXIN POWER CHUCK results from the ~1° shallow nose taper cone with helical slot inside the internal chuck bore. It exerts a very high clamping force when the clamping nut is rotated in the axial direction. The shallow taper in the tool nose and the angled position of the needle bearing that sit in the cage create the axial movement of the clamping nut.
Following are maximum static moment capabilities of the MAXIN holder:
- Dry clamping: 180 kg x m
- Oiled surfaces: 120 kg x m
When SC collets are used, torque transmission is reduced by 25%.
This unique clamping mechanism eliminates axial movement of the shank while clamping, simplifying the preset process.
For smaller tool diameters, the MAXIN power chuck requires the use of

SC straight collets as reduction sleeves. SC straight collet metric sizes: 6, 8, 10, 12, 14, 16, 18, 20 & 25 mm. These SC straight collets are available with an optional internal preset screw (8 & 9). Kits are available, each containing one MAXIN power chuck, 7 SC reduction collet sleeves, a wrench and a collet extractor, all in a wooden box.
Features:
- High accuracy runout at 100 mm overhang of 0.01 mm.
- Only a small tightening torque will develop an extremely high tool gripping force due to the unique anti-friction mechanism.
- High stiffness is achieved by the clamping mechanism using the face contact between the clamping nut and the face of the shank.
- Symmetrical design for spindle speeds up to 8,000 RPM.
- Prolonged tool life due to the high rigidity achieved by the system.
- Slim design for better accessibility in narrow/steep cavities.
- Preset screws available for all SC straight collets for positioning of the tool.
- The MAXIN tool is produced from a special sub-zero steel treated for vibration damping.
