Product Details

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.
