The toolholder is securely pulled into the spindle by the spindle’s clamping gripper using the pull stud. Pull studs come in different versions. They are an important link between the machine and tool. Stringent requirements apply for the accuracy, strength and reliability of pull studs.
- For tools with taper shanks see also DIN 69871 and JIS B 6339 (MAS-BT).
- In machining centres (machines with automatic tool changers).
- In NC machines (machines without automatic tool changers).
When installing the pull stud, cheque the correct tightening torque.
ISO 7388-3 meets the old standard DIN 69872.
