Cangzhou Yiheng Machinery Manufacturing Co., Ltd. has a complete resin sand production line, which produces various large machine tool bed, workbench, base, beam, column and other castings using resin sand process and EPC. For large and simple machine tool standard castings, wood or aluminum mold can be used for casting, which also improves the appearance quality and production efficiency of castings. Yiheng Casting Co., Ltd. integrates casting and processing, and provides customers with blanks and rough machining of machine tool castings according to drawings.
Detailed description:
Machine tool castings are essential basic castings in the mechanical operation process of machinery, machine tools, shipbuilding, automobile, electric power and other industries, also known as bed and base castings. Machine tool bed castings are mostly used as the bed of various large machine tools, and can also be directly used as machine parts through precision machining.
The machine tool castings produced and processed by Yiheng Machinery have the following "three high" characteristics:
1. High toughness: grey cast iron (HT250) with high carbon content is adopted, and the casting has strong hardness and high toughness after advanced heat treatment process;
2. High quality: graphite in cast iron is conducive to lubrication and oil storage, with good wear resistance and shock absorption performance; Resin sand molding is adopted to effectively eliminate shrinkage cavity and porosity defects.
3. High precision: A series of mechanical equipment such as milling machines, turning machines, drilling machines, planing machines and CNC machine tools can be used to provide rough machining and finish machining of machine tool castings.
Factors affecting the quality of machine tool castings:
1. Design process of casting. When designing, in addition to determining the geometric shape and size of the casting according to the working conditions and metal material properties, the rationality of the design must also be considered from the perspective of casting alloy and casting process characteristics, that is, obvious size effects and solidification, shrinkage, stress and other problems, so as to avoid or reduce the occurrence of defects such as composition segregation, deformation, cracking, etc. of the casting.
2. Reasonable casting process. That is to say, according to the casting structure, weight and size, casting alloy characteristics and production conditions, select the appropriate parting surface, molding and core making methods, and reasonably set up the casting ribs, chills, risers and gating systems to ensure that qualified castings are obtained.
3. Quality of raw materials for casting. Metal furnace charge, refractory, fuel, flux, modifier, casting sand, molding sand binder, coating and other materials directly affect the quality of castings. Yiheng Casting adopts the international famous brand "Shengquan" resin sand, curing agent, coating, etc., which greatly reduces and avoids the defects of machine tool castings such as air holes, pinholes, slag inclusion, sand sticking, etc., and ensures the appearance and internal quality of castings.
4. For process operation, reasonable process operation procedures shall be formulated. Yiheng Casting has a high-tech and efficient casting and processing team, rich experience in the casting and processing of various types of machine tools, and the development and implementation of reasonable process procedures.
