Cast Iron T-Slotted Bed Plates Floor Plates Base Plate
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 areoffered, 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.

Installation and adjustment
When used surface plate ,you should first installation
debugging,then you can use it . No significance work on surface
plate if they aren't properly positioned .Surface plate should
setup on level off, firm without shock place .please first put the
pad iron down ,then put the surface plate on the pad iron ,removal
the wooden case and oil . Measurement with the levelness of the
surface plate ,when the surface plate isn't level ,please adjust
the pad iron .( In the process of adjusting attention to safety)
Notice for use
1: To the best uniform use of the flat plate throughout, to avoid
local grinding concave.
2: Keep the plate clean, prevent be wroned by iron scrap, sand ...
3: Put down workpieces on the plate gently, prevent the flat
surface be impacted, once the plate surface hit the workpiece or
other objects,repair impact and the convex part immediately.
4: Do not do any hammer work on the surface plate .
5: After use, should be clean it. If long time no use should not be
coated with anti rust oil to prevent corrosion.
