The principle of the crafting route of the marking platform The formulation of the machining process of the cast iron scribing plate can generally be divided into two steps. The first is to formulate the process route of cast iron scribing and plate processing, and then determine the equipment used in each process, process size and process equipment, working hours quota, cutting specifications, etc. These two steps are interrelated and should be analyzed comprehensively. cast iron scribing plates The formulation of the cast iron slab process route is to formulate the overall layout of the process. The main task is to select the processing method of each working surface, determine the processing sequence of each working surface, and the number of processes in the entire process. The general principles for establishing a process route for cast iron scribing plates are as follows. 1. Process the datum surface first During the processing of the part, the surface as the positioning reference should be processed first, so as to provide a precise reference for the subsequent processing as soon as possible. It is called "benchmark first". 2. Divide the processing stages Surfaces with high processing quality requirements are divided into processing stages, which can generally be divided into three stages: rough processing, semi-finishing and finishing. The main purpose is to ensure the processing quality; facilitate the rational use of equipment; facilitate the arrangement of the heat treatment process; and facilitate the discovery of blank defects. 3. Hole first, then surface For parts such as square boxes, brackets and connecting rods, the plane should be processed first and then the holes should be processed. In this way, the holes can be positioned on the plane to ensure the position accuracy of the plane and the holes, and it is convenient to process the holes on the plane. 4. The main surface finishing (such as honing, grinding, fine grinding, etc.) should be carried out at the last stage of the process route to prevent the finishing surface from being damaged due to the transfer and installation between processes.

The casting methods of cast iron tables Small cast iron tables generally use resin sand. On the one hand, it is to facilitate sand removal. There are also the following reasons: 1. Relatively speaking, lost foam casting has great advantages over traditional sand molds for the production of single or small batches of automobile covering parts, machine tool beds and other large molds. It not only saves expensive wood mold costs, but also facilitates operation. , It shortens the production cycle, improves the production efficiency, and has the advantages of high dimensional accuracy, small machining allowance, and good surface quality. 　 2. The resin sand mold has good rigidity and high sand mold strength in the initial stage of casting. This makes it possible to use the graphitization expansion of the cast iron solidification process to effectively eliminate shrinkage and shrinkage defects, and achieve fewer and no risers for gray cast iron and ductile iron. 3. In the production of solid casting, polystyrene foam is used to form furo resin self-hardening sand. When the molten metal is poured into the mold, the foamed plastic pattern quickly vaporizes under the action of the high- temperature molten metal, burns and disappears. The molten metal replaces the original foamed plastic position, and cools and solidifies into a solid casting with the same shape as the pattern. cast iron table Jinggong Measuring Tools Producing Co., Ltd is specializing in manufacturing and exporting all kinds of cast iron products，especially for cast iron floor plates, cast iron surface plates, cast iron clamping plates, cast iron angle plates, cast iron box table and other machine tool castings.

Characteristics and methods of castings Casting is a forming method in which molten metal liquid is poured into a mold similar to the shape of the part, and after cooling and solidification, a blank or part with a certain shape and performance is obtained. 1. Casting and its characteristics Castings are generally blanks, which need to be cut before they can become parts. Parts with lower precision requirements and larger surface roughness parameter values, or castings produced by special casting methods can also be used directly. 2. There are many casting production methods, and there are two common types: a. Sand casting: a casting method in which molding sand is used to form compactly. The source of molding sand is wide, the price is low, and the sand casting method is adaptable, so it is the most basic casting method used in production at present. b. Special casting: other casting methods different from sand casting, such as investment casting, metal mold casting, pressure casting, low pressure casting and centrifugal casting. casting of cast iron plates 3. Casting production has the following advantages: a. Can be made into blanks with very complex shapes and cavities. Such as various boxes, beds, racks, etc. b. Wide application range. It can cast workpieces of different sizes, weights and shapes; it is also suitable for different materials, such as cast iron, cast steel, and non-ferrous alloys. The weight of castings can range from a few grams to more than 200 tons. c. Wide sources of raw materials. Scrap parts or chips can also be used; the cost of process equipment is small and the cost is low. d. The size of the obtained casting is close to that of the part. It can save metal consumption and reduce the workload of cutting. However, castings also have disadvantages such as poor mechanical properties, many production processes, unstable quality, and poor working conditions of workers. With the development of casting alloys and casting technology, especially the development of precision casting and the successful application of new casting alloys, the surface quality and mechanical properties of castings have been significantly improved, and the scope of application of castings has been expanding. Jinggong Measuring Tools Producing Co., Ltd is specializing in manufacturing and exporting all kinds of cast iron products，especially for cast iron floor plates, cast iron surface plates, cast iron clamping plates, cast iron angle plates, cast iron box table and other machine tool castings.

Why are T-slots on T-slots platform easy to error? The T-slots platform is often very prone to errors in the T-slot planed by the platform due to operating errors. The following four are the main reasons. cast iron T-slots platform 1. The groove of the T-slots platform is not parallel to the side of the platform working surface. The main reason is that the cast iron platform is not aligned according to the markings during installation, or the cast iron platform is displaced during processing. 2. The top surfaces of the left and right grooves of the T-slot are not on the same plane. The reason is that the machine tool setting is not accurate. The width of the main cutting edge of the left and right variable cutters is not the same when the groove is processed in one pass. 3. The width of the left and right grooves of the T-slot platform is different. The main reason is that the slot direction is not well mastered. 4. There is a shallow groove in the middle of the T-slots bottom surface of the T-slots platform. The reason is that the tool is not well connected when processing the bottom surface of the groove, or the planing is too deep when processing the right-angle groove. Jinggong Measuring Tools Producing Co., Ltd is specializing in manufacturing and exporting all kinds of cast iron products，especially for cast iron floor plates, cast iron surface plates, cast iron clamping plates, cast iron angle plates, cast iron box table and other machine tool castings.
