Product features
Shars
tools are manufactured by an
ISO 9001
certified manufacturer with 60 plus years of hands-on experience in
the CNC machining industry. Shars tools manufacturer is also an OEM that produces highest quality European brands. The manufacture really pays attention to the details onthe retention knob, as shown here on the flange, the straight neck, and the pilot.  Each knob goes through a magnetic particle test after heat treatingto prevent crack line’s and after this testing procedure, each knob will be precision ground on all critical contact surfaces, including the pilot underneath the flange area.  The pilot will ensure the retention knob body makes a better contact with the tool holder next to the threads which will reduce the vibrationand minimize TIR on the overall system (tools holder + retention knob).
Other low price import pull stud are made from
45 medium carbon steel
, but
Shars
pull stud is made from fine
alloy steel, 20CrMnTi
with heat treatment to HRC 56-58
,
which is equal to
USA material 8620,
better
performance than
45 medium carbon steel
. The price for 20CrMnTi is double of
45 medium carbon steel
.
After
the
forging process, the raw material can
maintain the mechanical performance and flow line
.
This will
ensure the
life and stability of the material, after the material
has been run through several heat treatment processes.
Using high quality alloy steel 20CrMnTi forging, the material is metallographic dense, uniform and stable. After carburizing, the outside of
material is
hardened, and the inside of material is still soft and has enough toughness. Therefore, Material has higher wear resistance and better toughness.
Other low price import pull stud’s are machined by a turning process, but
Shars
pull stud’s are fully ground by CNC on all critical surfaces including a pilotunder the flange of retention knob for full contact between tool holder's taper end and retention knob. Precision grinding pull stubs have higher surface finish and dimension accuracy.  T
he fitting accuracy is obviously higher than that of machine pull stubs, effectively reduces the error of
machine tool and
cooperation, so as to improve the accuracy and stability of the connection and
improves the precision of the machine tools and lengthens the service life.
Precision finished on the bottom of the flange to improve fitting with the bottom nose of the taper on the tool
holder
For details of the processing quality of ground pull studs surface finish, please see the following picture
which
shows the pull stub by half black oxide finish.
High quality black oxide finish can ensure long pull stub life and a non-rusting surface. The following picture
shows the pull stub after black oxide finish
Magnetic particle inspection is used for crack detection to avoid accidents from occurring because of micro defects.
Retention knobs are magnetic particle tested before left manufacturer. The following picture shows Crack detector.
This pull stud is compatible with the following:
