Cast Iron Cross T Slot Plate For Motor Test Bed Customized Shape
Color
Features of our T-slotted cast iron floor plates:
- Material is high-strength, high-density and close grained gray cast
iron available at Grade of GG-20, GG-25 or GG-30 are to be chosen
to manufacture the t-slotted cast iron floor plates. Other materials such as nodular cast iron or cast steel can also
be used on request;
- The ribbed & cored structure offers the premium rigidity and
strength for the t-slotted cast iron floor plates. The solid structure can also be offered as per your
request.
- Hardness for GG-25 gray cast iron made t-slotted floor plates is in
the range of HB170-240. The surface flatness accuracy on the top
surface of the t-slotted cast iron floor plates is available as
being Grade I, II or III as per DIN 876 Standarad. The higher
flatness accuracy can be obtained by hand scrapping upon your
request. Surface roughness on the t-slotted cast iron floor plates
is usually Ra 3.2 μm obtained by adopting the CNC high-speed
milling process. Lower roughness such as Ra 1.6 μm can also be
achieved by grinding process on your request;
- The width tolerance of T-slots on the t-slotted cast iron floor
plates is H12 and could also be H7 or H8 on request. Usually
T-slots parallel to the longitudinal direction are offered, but
also T-slots tilting to the longitudinal direction can be offered
on request. You can also request for both longitudinal and cross
t-slots on these t-slotted cast iron floor plates;
- Cored and ribbed construction, twice annealing heat treatments at a
temperature in the range of 600-700° C (the 1st annealing is done
right after casting, the 2nd annealing is done right after the
rough machining on the plate) and the following aging treatment are
implemented on these t-slotted cast iron floor plates to relieve
the stress to the minimum, ensure high stability and maintain its
accuracy free from distortion;
- Connecting grooves on all sides of the t-slotted cast iron floor
plates can be provided on request to joint together the pieces of
plates into a large plate area;
- Leveling and anchoring pads are supplied with the plates. Vibration
absorbing spring mounts can alsot be provided on request;
- Size of each piece of t-slotted cast iron floor plates is available
in a range from 1000x1000 mm to 10000x4000 mm. Other sizes can be
made on requests.
Precision: According to the national standards measurement examination
regulations execution,
respectively is 1,2,3, fine polish.
