How to process polyurethane by lathe? How to turn polyurethane

This material is soft and flexible. It is more difficult to process soft materials than hard materials. The best way is to machine white steel cutters with high-speed steel turning tools.

Sharpen the knife, open a large cutting groove, the roughness of the groove surface is greater than that, try to adjust the high-speed machining, keep it cylindrical processing, and then turn the sleeve of the same diameter first, add some hot sleeves, and the sleeve is smooth.

The roughness of the sleeve is required to be: If a water drill can make the drill bit smooth, the drilling hole is brighter and more beautiful than turning, the white steel tool can be sharpened, and the tip of the knife can be cut like a needle at high speed, which is very useful.

Application fields of PU products

China is the world's largest furniture production and processing country, combined with the "Twelfth Five-Year Plan" period of the total consumption of polyurethane in the furniture industry; During the "13th Five-Year Plan" period, China's furniture industry is still to expand domestic demand, stimulate urban consumption, with the tightening of China's real estate policy, the construction of affordable housing and low-rent housing will continue to accelerate, China's furniture industry will not be impacted, the public's demand for polyurethane will grow at a rate of 5% per year.

In the furniture industry, imitation wood material is one of the main application directions of polyurethane rigid foam, imitation wood material is light in quality and density, strength is equivalent to wood, the use of this material to manufacture furniture, not only will not appear cracks after molding, but also reduce the cost of manufacturing. With the increasing awareness of national environmental protection, imitation wood materials will be more used in the furniture industry, so as to replace the position of natural wood in furniture.

The diameter is 15 rods, processed to 10, I don't know how long, if in mm long, can be directly turned, and then long need to use a tool holder, the key is the tool, you can use a white steel knife, the sharper the sharper the processing.

Knives sharpened with high-speed steel blades or sharpened with high-speed steel saw blades are preferable, and blade-like cutting edges are best.

Like metal materials, it is enough to cut directly on the machine tool.

1. The full name of polyurethane is polyurethane.

It is a general term for macromolecular compounds containing repeating carbamate groups on the backbone. It is made by the addition of organic diisocyanates or polyisocyanates with dihydroxyl or polyhydroxy compounds.

2. Polyurethane material.

It has a wide range of uses, and can replace rubber, plastic, nylon, etc., for airports, hotels, building materials, automobile factories.

Coal mines, cement plants, high-end apartments, villas, landscaping, colored stone art, parks, etc.

First of all, I would like to explain that the turned polyurethane is a cast CPU.

The polyurethane CPU should be poured into a cylinder or bar first, and then the cylinder or bar should be installed on a moldless sealing processing equipment (similar to CNC lathes for processing metal parts) for processing, without opening the mold, directly turning out the sealing ring of any section.

Of course, this equipment can not only be made of polyurethane, but also rubber, polyoxymethylene, tetrafluorine, nylon and other materials.

Here is a reminder that these materials for turning have hardness requirements, taking polyurethane as an example, about 95A.

Like metal materials, it is enough to cut directly on the machine tool.

Due to the high elasticity of the material, the CDW20 series of diamond tools can be used, which can avoid the entanglement of "iron filings" when turning polyurethane.

Diamond knives are suitable for polyurethane turning.

Professional mold-free turning and sealing equipment!

Hello answer, this is Xiaodu, happy to answer your questions. It can be turned, but it is not easy to process, this material is soft and elastic, and it is more difficult to turn soft materials than hard materials, and the best way is to use high-speed steel turning tools to process commonly known as white steel knives. The knife is sharp, open a large cutting groove, the roughness of the groove surface is above, adjust the high-speed processing as much as possible, leave the millimeter for the outer processing, and then use the sleeve of the same diameter of the first car, the sleeve will be smooth with a little hot sleeve, the roughness of the set is required, if there is a hole drill bit with water to hit the smooth, the drilling is brighter and beautiful than the outer circle of the turning, and the cutting can grind the white steel cutter to millimeters, and the sharp head is very effective for high-speed cutting like a needle.
