BT Pull Stud 45 Degree Pull Studs: CNC Chuck-Tool Holder Connection, Automatic Clamping Tool
The cnc pull stud of the tool holder is tightened. When changing the tool, the tool holder should be loosened. The automatic clamping mechanism of the tool inside the spindle is the special mechanism of the CNC machine tool processing center. The drawing shows the structure of the spindle of the machining center. The cutter can be loaded and unloaded automatically on the spindle and clamped automatically. The working principle is as follows: when the cutter 2 is loaded into the spindle hole, the pull pin 3 at the back of the handle is sent to the front of the spindle pull rod. Under the action of the disc spring, the cutter is tightened by the elastic claw.
BT Pull stud 45 Degree pull studs : one end of the cnc pull stud is
connected with the machine tool chuck, the other end is connected
with the tool holder, the d part is clipped in according to the
degree of the machine tool chuck, and the G part has threads and
knife handle tightening. Through the axial force transmitted by the
cnc pull rod, the pull rod joint and the cnc pull stud, the tool
holder is tightened. When changing the tool, it is required to
loosen the tool holder. When the cnc pull stud is installed on the
spindle of the common machine tool or the numerical control machine
tool, the arc joint of the rod body is connected with the front end
of the pull rod structure. The screw joint of the cnc pull stud is
connected with the inner screw hole of the tool holder extending
into the spindle hole, thus realizing the use of the tool holder on
the common machine tool and the numerical control machine tool. The
tool holder can be used not only in machining centers, but also in
common machine tools and CNC machine tools, which improves the
universality of the tool holder and reduces the production cost.
Retention Knob for BT Tool Holder 45° Pull Stud,BT pull stud Aging treatment 20-40 h super-long heat aging removes residual internal stress during grinding. Deep cooling treatment and thermal aging treatment can reduce residual stress and improve durability and accuracy stability.Adopt surface coating technology to improve the anti-wear ability of the surface, better anti-rust and anti-corrosion effect, more stable accuracy, smoother surface and more beautiful appearance.

1. The ultra-long cryogenic treatment at - 185 C transforms nearly
all residual austenite into martensite.
2. Precipitated nano-carbide particles increase hardness and
toughness.
3. Reducing residual stress;
4. The wear resistance is improved significantly.
