Features of龙门planer casting:

One.龙门刨床 castings have good vibration damping properties. Since graphite in cast iron is beneficial for lubrication and oil storage, it contributes to this. Similarly, the vibration damping due to the presence of graphite is superior to that of steel.

Good process performance. Due to the high carbon content of gray cast iron, which is close to eutectic composition, it has a relatively low melting point, good fluidity, and low shrinkage rate, making it suitable for casting complex structures or thin-walled castings. Additionally, because graphite facilitates chip formation during cutting, the machinability of gray cast iron is superior to that of steel.

Three, Good vibration damping. Due to the graphite in cast iron, which is beneficial for lubrication and oil storage, it is good. Similarly, due to the presence of graphite, gray cast iron has better vibration damping properties than steel; good process performance. As gray cast iron has a high carbon content, close to eutectic composition, its melting point is relatively low, with good fluidity, low shrinkage rate, making it suitable for casting complex structures or thin-walled castings. Additionally, due to the graphite, the cutting... Chipping is more prone during machining, thus gray cast iron has better machinability than steel.

Four, the relationship between hardness and tensile strength: There is a corresponding relationship between the hardness and tensile strength of gray cast iron, with the empirical formula being: aPlease provide the Chinese content to be translated.O≥196N/mmsq. mHB=RH(Fly00+0 4380b) (B1) bWhen0≥796N/mmsq. mHB=RH (44+O 7240b) (B2) Relative Hardness(RH)The value is primarily determined by the raw materials, melting process, finishing process, and the cooling rate of the casting.

V. Advantages of casting machine bed components using resin sand molds 1Resin sand molds offer excellent rigidity, allowing for the utilization of the graphite expansion during the iron casting solidification process in the early stages of pouring. This helps to minimize defects such as shrinkage holes and shrinkage porosity, enabling low or no riser casting for gray cast iron and ductile iron components.2In the production of solid castings, polystyrene foam patterns are used with furfuryl resin self-hardening sand mold making. When the metal liquid is poured into the mold, the foam plastic pattern vaporizes and burns under the action of the high-temperature metal liquid, disappearing. The metal liquid takes the place of the original foam plastic, cooling and solidifying into a solid casting with the same shape as the pattern.3Compared to traditional sand casting, the lost foam casting process offers significant advantages for producing single or small batch automotive coverings, gantry planer bodies, and other large molds. It not only eliminates the costly wooden mold expenses but also simplifies operation, shortens production cycles, and boosts efficiency. It boasts advantages such as smaller dimensions, minimal machining allowances, and superior surface quality.

Casting Technical Inspection Process for龙门Planer

One: The rough casting of planer parts must not have casting defects such as sand holes, shrinkage porosity, cracks, etc.

Two, castings must undergo annealing treatment.

Three, castings must be cleaned.

Four, castings should be sprayed with rust-proof paint.(Optional)。
