Cast iron platform included : Three-dimensional flexible welding base platform, crossed platform, the basic platform, grinding platform, riveting platform, standard crossed platform, bench pliers, T-slot platform (T-slot plate) Inspection platform, assembly-level, welding platform, and other cast iron measuring products.

Material: cast iron plate using HT200-300 casting, material ingredients ingredients and ingredients according to the following criteria (%): carbon: 3.1-3.4, manganese: 0.6-0.9, silicon: 1.5-2.0, sulfur <0.12, phosphorus < 0.3. Hardness> 180, the second tempering treatment.

Cast iron plate It is specially designed for the flattening of large equipment with reasonable design, stable structure, high precision and abrasion resistance. It can be used for flattening from 3000mm to 6000mm. The product is made by scraping or grinding. Measurement, and grinding of machining centers, tool shops, machine shops, inspection and maintenance workshops, large-sized equipment bases, measuring chambers and precision machining, and accurate measurement and inspection of the flatness, flatness and angle tolerance of workpieces. .

Repair mold / cast iron platform T-groove flat working surface is the workpiece and fixture positioning reference, and movement between the direction of a certain relationship, in order to make the workpiece and cast iron flat face contact close and reliable, the plane (Vertical, horizontal, diagonal, radiation) on the straightness error in the maximum value as the work surface of the flatness error.The measurement method and guide the straightness of the measurement The method is basically the same.Use point method, plug-foot method, level and optical flatness and other methods of inspection.

1, the platform must be subject to two back stress stress aging treatment, to prevent the deformation of stress memory distortion and the future use of the platform into the phenomenon of cracks in the occurrence of the elimination of casting stress, the purpose of rough stress, stress relief of 90%

2, the end of the working face after the acute blunt;

3, the casting surface to be processed without external force, polished, the inner surface are required to paint anti-rust paint;

4, flat face can not seriously affect the appearance and performance of sand holes, pores, cracks, slag, shrinkage, scratches, bumps, rust and other defects.

3, the accuracy grade 0 ~ 3 flat working surface, the diameter of less than 15mm of sand holes allow the same material blockage, the hardness should be less than the hardness of the same material.Faceface blocked sand holes should not be more than 4 And the distance between the sand holes should not be less than 80mm.

4, the plate should be high-quality fine gray cast iron or alloy cast iron and other materials, the face hardness should be 170 ~ 220HB.

5, the flat face is usually applied to use scraping process.For scraping the three-stage flat working face, the surface roughness Ra of the maximum allowable value of 5чm.

7, the flat face with the scraping process should be carried out on the color of the test. The proportion of contact area after the inquiry shown in Table 3, or 25mm × 25mm in the number of points of contact should not be greater than 5 points Controversial, according to the ratio of contact area for the assessment basis.

8, the plate relative to the two sides, there should be installed handle or ring device screw hole (or cylindrical hole), and the device location should be designed to minimize the deformation caused by handling.

9, if the flat face set on the working hole (or groove), the location should not be higher than the face.

Botou Yongjun Measuring Tool Company Profile

Is located in the southeastern part of Hebei Province, north of Beijing and Tianjin, east of Bohai Sea, 104, 106 State Road, Beijing-Shanghai high-speed, Beijing-Shanghai railway runs through the whole territory, transportation is extremely Convenient. My company mainly produces cast iron platform, special-shaped castings, machine tool castings, bed castings, square box square tube, V-shaped V-type iron. Our company has always been to adhere to the people-oriented, science and technology as a guide to innovation and development. Enterprises in the introduction of the world's advanced technology, the introduction of a large number of professional and technical personnel, the expansion of advanced production equipment, enterprise technology is becoming increasingly strong, economic strength is also growing and growing.

First, strict control of raw materials purchase material, followed by strict control of precision casting process, and finally a series of tests: a furnace material testing, furnace temperature measurement, ultrasonic testing of finished products and hardness testing. Appearance allows customers to rest assured that satisfaction.

Company to market-oriented, customer-focused, technology-based, strengthen brand awareness, enhance service levels, the future, and constantly forge ahead, and strive to develop into a sound management system and comprehensive competitive advantages of science and technology enterprises
