Description
Technical Field
The invention relates to the technical field of cutters, in particular to a surface texture cutter for machining vermicular graphite cast iron and a preparation method thereof.
Background
Vermicular cast iron is a new material with excellent material properties. The phases having a relatively high content in the cast iron include ferrite, pearlite and graphite, and the cast iron may be classified into spheroidal graphite cast iron, gray cast iron, vermicular graphite cast iron, etc. according to the morphology of the graphite. The graphite in nodular cast iron exists in spherical form, the graphite in gray cast iron exists in the form of randomly oriented flakes, while the graphite form in vermicular cast iron is between that of nodular cast iron and gray cast iron, and the graphite form is mainly vermicular with round edges. Graphite in vermicular cast iron is shorter, thicker and connected with each other to form a grid coral shape, and the connection with ferrite in a substrate is tighter, so that the vermicular cast iron has more excellent mechanical properties. Compared with the traditional gray cast iron, the tensile strength of the cast iron is 2-3 times that of the gray cast iron, the strength and the rigidity of the cast iron are 1 time stronger than those of the gray cast iron, and the cast iron has good high-temperature performance below 500 ℃, but the mass of the cast iron is half lighter than that of the traditional gray cast iron. Due to the excellent performance of the vermicular graphite cast iron, the vermicular graphite cast iron can be widely applied to parts such as engine cylinder bodies, cylinder covers, exhaust pipes, piston rings, brake discs and the like, and the manufactured engine has the characteristics of small volume, high strength and low energy consumption and has good development prospect in the field of engines.
However, the more excellent properties of vermicular cast iron also result in poorer processability. The higher tensile strength leads to higher cutting force in processing and higher required processing power; the higher toughness of vermicular cast iron makes it more prone to sticking to the knife and thus increasing wear; the low thermal conductivity causes the cutting heat to concentrate at the tip portion, so that the thermal wear is intensified. The sulfur content of the vermicular cast iron is extremely low due to steps in the manufacturing process of the vermicular cast iron, so that a lubricating film is not easy to generate on the surface of the vermicular cast iron to aggravate abrasion; titanium during production can form high strength carbides during machining resulting in reduced tool life.
Therefore, how to reduce the wear of the tool for processing the vermicular cast iron and prolong the service life thereof is a technical problem to be solved by the technical personnel in the field.
