Bench platform Made of HT250,HT300 material, by the use of high grade gray iron, and SuperbCasting process of completely avoiding the blowhole casting defects such as Chlamydia trachomatis, and the appearance of smooth, small machining allowance. Can be tailor-made according to customer demand, truly as you say, acceptable to figure-made, precision up to 0, cast iron cast iron platform t-slot platform Is a kind of industrial measuring tools, mainly used to fix the workpiece are fitter workers used to debug device, Assembly equipment, repair equipment based platform. Level plate deflection should not exceed level 00 of plate flatness tolerance value in half. A variety of experimental platform in Central concentrated load in working face area, cast iron plate length width height, surface of the cast iron plate, the weight of the cast iron plate, cast iron plate material requirements, and so on. Technical requirements of design cast iron plate in accordance with the People's Republic of China mechanical industry standard JB/T7974-2001 design, and according to actual need according to the technical requirements of cast iron plate.

Cast iron plate Specifically applied to large equipment base levelling, reasonable design, structural stability, high precision, wear-resistant characteristics of 3000mm-6000mm Tablet mosaics can be realized, the product is made by scraping or grinding. Widely used in machining, tool shop, machine (test) repair shop, large equipment base, measuring and precision machining of test, measuring and grinding, and precise measurements, test the flatness of the workpiece, flatness and the tolerance value.

Repair work platform/cast iron Accuracy of the face is mainly flat. T-slot of the workpiece and clamp plate face is the positioning and movement between the direction of the relationship, in order to make reliable and cast iron flat face contact, its flatness is generally provided for in the concave. Countertops in all directions (vertical, horizontal, diagonal, radiation) on the straightness of the maximum values as a table surface flatness. With Rails straightness measurement method measurement method is basically the same. Available research points method, feeler gauge method, leveling instrument, optical flatness measuring instrument and method of inspection.

Cast iron platform technical requirements:

1, the platform must go through two back stress aging treatment, prevent stress memory appears distorted and platforms used in the occurrence of cracks in the future to eliminate casting stress and rough purpose of stress, strain relief up to 90%;

2, face processing acute angle obtuse;

3, casting force is not machined surface greasy, polishing, are required to paint coating on the inner surface;

4, flat face without seriously affecting the look and performance of sand, pores, cracks, inclusions, porosity, scratches, bumps, rust and other defects.

3, precision is 0 ~ 3-level on the flat face of diameter less than 15mm blockage of sand allows the use of the same materials, its hardness is less than with the hardness of surrounding materials. Sand blocking the face-hole should be no more than 4. And sand between the distance should not be less than 80mm.

4, plate shall be made of high quality fine grey cast iron or alloy materials such as cast iron, its working surface hardness should be 170~ 220HB.

5, flat working surface is usually applied using a scraping process. Skiving machining of 3 flat working surface, the surface roughness Ra of the maximum allowable value of 5 ч m.

7, flat face paint for the Institute tests should be carried out using the scraping process. Displayed after the grinding point of contact area ratio is shown in table 3 provisions or 25mmx25mm difference between points of contact shall not be more than 5 points. In case of disputes, contact area ratio as the assessment basis.

8, flat on either side, should have a threaded hole of the handle or ring equipment installed (or a cylindrical bore), and location of the device should be designed to minimize the deformation caused by the handling.

9, plate set screw hole on the face (or Groove), which parts should be no higher than the face.
