Material is high-strength, high-density and close grained gray
cast iron available at Grade of GG**0, GG**5 or GG**0 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**5 gray cast iron made t-slotted floor plates
is in the range of HB******0. 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 **6 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 H*2 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 ******0° 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 ***0x***0 mm to ****0x***0 mm. Other
sizes can be made on requests.
