  • Hydraulic Cartridge Flow Control Valve With Cylindricity Of 0 003mm - China

    price: 120.00 Dollar US$

    The hydraulic cartridge flow control valve with a cylindricity of 0.003mm, the technology used by AAK is unexpected by peers Edgar is from a hydraulic company in Britain and has been engaged in procurement for 2 years.

    Recently, the supervisor asked him to purchase a hydraulic cartridge flow control valve with a rated pressure of 15~20MPa, a fit clearance of 0.012~0.015mm and a cylindricity of 0.003mm.

    The supervisor specially emphasized that this was the project the boss was looking at.

    Edgar saw the parameters of this hydraulic cartridge flow control valve and was a bit stunned.

    It was difficult for his current hydraulic cartridge flow control valve manufacturers to reach the standard.

    Although one of the manufacturers promised to be 90% sure, the cylindricity accuracy could not be approved, because the processing of the blind hole of the hydraulic cartridge flow control valve was not sufficient enough.

    He failed to meet the standard even after 3 adjustments.

    More than a month has passed, and no progress has been made.

    Edgar was very worried.

    I'm not sure where Edgar learned about AAK.

    He left a message on our website: Can you process the hydraulic cartridge flow control valve with a cylindricity of 0.003mm? Because the parameters are not the only factor, we cannot simply answer yes or no.

    I can only tell him that the problem of the original hydraulic cartridge flow control valve manufacturer lies in the tool, and most hydraulic valve manufacturers still use traditional diamond reamers.

    This technology is not only highly demanding for technicians, but the tool is also easy to wear.

    In diamond reamer cutting, the force is mainly concentrated on the tool head, and the head wears quickly.

    This makes the hole bottom size smaller and affects the cylindricity of the valve hole.

    Edgar should have felt that AAK pointed to the point, so he sent us the complete drawing of the hydraulic cartridge flow control valve, informing us of the above procurement difficulties, hoping that AAK could help him with solution.

    According to Edgar's drawings, I told him that AAK should make samples directly.

    If it is not successful, the development cost will be returned.

    After 30 days, 6 hydraulic cartridge flow control valve samples were sent out.

    3 weeks later, Edgar sent a PO for hydraulic cartridge flow control valve worth 20, 000 US dollars.

    At the same time, he advised that their engineers were very satisfied with AAK samples and required that the manufacturing quality of mass production must be the same as the samples.

    I told him that the shipment will be the same as the samples, it was more difficult for the workshop to do a little worse than to do a little better.

    Edgar was curious about what technology AAK used to solve the cylindricity problem of the hydraulic cartridge flow control valve.

    3 years ago, AAK realized that the cylindricity of the valve hole would have hidden problem due to the traditional diamond reamer processing technology, so we replaced it with new honing machine, and the the diamond reamer was replaced by diamond oilstone, which is installed on the special honing rod.

    The oilstone can expand and shrink radially, gradually cut off the allowance of the valve hole, and is equipped with an automatic measuring system.

    After rough honing, the diameter of the valve hole can be measured 360 degrees.

    If the size is abnormal, the oilstone will correct it.

    In this way, the cylindricity of the machined valve hole can reach 0.0025~0.003mm, moreover, the surface roughness is Ra0.2 - Last week, Edgar told me privately that his boss paid more and more attention to him after the smooth delivery of this hydraulic cartridge flow control valve.
