Cast iron platform

The characteristics of gray cast iron parts: wear resistance and good shock resistance, because of graphite in the cast ironis conducive to lubrication and oil storage, so good wear resistance. Similarly, due to the existence of graphite, the shockresistance of gray cast iron is better than that of steel. Process performance is good, because of the high carbon content ofthe gray cast iron, close to the eutectic composition, so relatively low melting point, good fluidity, shrinkage of small, so it issuitable for casting of complicated structure or thin-walled castings, the graphite machining easy formation of chip breaking,so grey cast iron can machinability is superior to that of steel.

Product description

　　T-slot platform, also known as T-slot workbench, is a kind of industrial measuring tool. It is mainly used to fix workpieces. It is the basic working platform used by fitters to debug equipment, assembly equipment and maintenance equipment.

The hardness of the high-strength cast iron HT200-300 is HB170-240. After two manual treatments (artificial annealing 600-700 ° and natural aging 2-3 years), the product has stable precision and good wear resistance.

In the production process of the T-slot platform, a part of the theoretical weight deviation will occur. It should be noted that the deviation of the cast iron plate is not affected by the cast iron plate. Generally, the design of cast iron plate should take into account the error of casting and machining. The weight error of cast iron plate should not exceed 10%. When it exceeds 10%, we must further identify the quality of cast iron plate to determine whether this cast iron plate is Can be put into use.

There are some product defects in the production process of the T-slot platform. As long as the correct method can be used to make up the process, the defects of the cast iron plate working surface are important parts that can not be ignored. The main defects of the cast iron plate include: air holes, sand holes, Sanding, shrinking, etc. Therefore, when repairing the defects of the cast iron plate, it must be handled strictly according to the process requirements.

The T-slot platform is mainly a flat reference gauge for workpiece inspection or scribing, and is an indispensable basic tool in mechanical manufacturing.

The working surface of the T-slot platform adopts the scraping process, and the working surface can process V-shaped, T-shaped, U-shaped grooves and round holes, long holes, etc., which can be used to fix the power machinery equipment.

Material of the T-slot platform: HT200. The hardness is HB170-240.

Specification: 200*200-3000*6000mm (special specifications are processed according to the drawings of the demand side or agreed upon by both parties).
