What are the technical requirements for the floor boring machine worktable?

The floor boring machine worktable is used for matching with floor boring machines, milling machines, and boring and milling machines. It is used for machine tool processing operations and has holes and T-shaped grooves on it to fix workpieces and organize iron filings generated during processing. Common channels for machine tool operation include: floor boring machine worktable, gantry milling machine worktable, etc.

The floor boring machine workbench is specifically suitable for power testing and equipment debugging of machinery and engines. It has good flat stability and durability, and has a T-shaped groove on the surface, which can be used to fix the testing equipment; Suitable for inspection of various products, including cast iron channels. The reference plane used for precision measurement, machine tool worktable, and cast iron machine tool channel are also used for mechanical inspection and measurement reference of machine tools. The machine tool worktable is used to check the dimensional accuracy or behavioral deviation of parts and make lines. It is also an essential basic element in mechanical manufacturing.

The floor boring machine worktable is a commonly used benchmark positioning tool in mechanical measurement, also known as a horizontal floor boring machine worktable. Generally, it needs to be leveled before use, and some even need to be leveled. I often need to buy other equipment, especially some small boards that have a relatively light weight, so adjusting the equipment is relatively heavy and the horizontal value will also move when placed in different places.

Technical Requirements

The working surface of the floor boring machine workbench shall not have defects such as sand holes, air holes, cracks, slag inclusions, shrinkage, scratches, bumps, rust spots, etc. that seriously affect the appearance and performance.

The casting surface of the floor boring machine worktable should be tidied and leveled with sand, and painted firmly.

On the working surface of the floor boring machine worktable with accuracy registered as level 0-3, sand holes with a diameter less than 15mm should be blocked with the same data, and their hardness should be lower than the hardness of the surrounding data. The number of sand holes blocked on the working face should not exceed 4, and the distance between sand holes should not be less than 80mm.

The worktable of the floor boring machine should be made of high-quality and fine gray cast iron or alloy materials, and its working surface hardness should be 170-220HB.

The working surface of the floor boring machine worktable should usually use scraping technology. The maximum allowable value for the surface roughness Ra of the working surface of the 3-level floor boring machine worktable selected for scraping processing is 5um.

The flatness tolerance of the working surface of the floor boring machine worktable is specified in Table 2.

The selection of scraping technology for the working surface of the floor boring machine worktable should be subject to color matching and inspection. The ratio of touch point area displayed after research is shown in Table 3, or the number of touch points in a 25mm x 25mm square area is shown in Table 3, and the number of touch points in any 25mm x 25mm area should not exceed 5 points.
