Characteristic

Model : 3X5DIN

The DIN spindle grippers are designed in accordance with DIN 69872 standard, featuring male-threaded pull stud interfaces and M45 mechanical amplification structure to provide enhanced clamping force with minimal release resistance. This ensures stable and fast tool clamping operations, especially in high-speed or high-rigidity CNC spindle systems.

Standard clamping angle α = 15°, offering a balance of force and stability
Compatible with spindle taper types: DIN30 / DIN40 / DIN50 / DIN60
Thread size ranges from M10 to M30 for higher torque capacity
Defined “Clamping Position (SS)” and “Release Position (LS)” shown in diagram
DIN60 features extended release stroke with ha = 1.15mm
