SK40 Pull Stud Retention knob ISO 7388 B
SK40 Retention knobs Pull Stud ISO 7388 B
High-quality low-carbon alloy steel is used for thread processing after quenching.
This type of stud shank has high hardness, wear-resistance, and long service life.
The hardness from the surface of the nail to the core gradually decreases, and the impact resistance is strong.
The size standard is suitable for high-end tool holders; the appearance is all black,
with high internal quality and Good rust effect, widely used abroad, a key recommendation
SK40 Retention knobs Pull stud working principle
The working system of the tool holder pull stud: one end of the pull stud is connected to the machine tool bayonet and one end is connected to the tool holder, and the d part is snapped in according to the degree of the machine tool bayonet, and the thread and the tool holder are tightened.
The axial force transmitted through the pull rod and Tie rod joints and pull studs to tighten the handle. When changing the tool, it is required to loosen the tool holder. When the pull stud is installed on the main shaft of the ordinary machine tool or CNC machine tool, the circular arc joint of the rod body is connected to the front end of the pull rod structure, and the screw joint of the pull stud is extended into the spindle shaft hole.
The internal screw holes of the tool holder are matched and connected to realize the use of the tool holder on ordinary machine tools and CNC machine tools so that the tool holder can be used in both machining centers and ordinary machine tools and CNC machine tools, which improves the tool holder. Versatility reduces production costs.
