Precision Machining

Precision Machining

Kuai Ma Steel provides precision honing services to meet customers' needs for a wide range of seamless tubes and precision tubular components. Depending on the alloy being machined, gun drills often leave a finer polished surface than Ra 125 on the inside of the seamless tube. In some applications, this surface treatment is acceptable or even preferable. However, in other applications, a smoother surface finish is required to optimize the overall performance of the part. Machinists at Kuai Ma Steel have the experience needed to effectively drill a wide range of sizes to exacting dimensional, concentricity and finish specifications.
Honing is a precision machining process that uses various abrasives to remove small amounts of material from the hollow interior of seamless tubes. Honing is a slower grinding process than grinding. The finish, size and precision of the final product are not affected by thermal stress due to less heat and pressure being generated. Precision honed tubes offer excellent surface integrity and finish, precise ID tolerances, and overall dimensional and geometry control not possible at higher cutting speeds.

Honing is a cost-effective method of machining extruded tube blanks to the precise wall thickness and finish specified by the customer. This helps save project costs. Kuai Ma Steel can repair extruded seamless tubes instead of starting from a solid bar. Then, according to the customer's specification, we can hon the tube to improve its finish and produce the precise bore diameter required. Kuaima Steel's honed tubes are 50mm-2000mm or larger. Our workshop is equipped with several Sunnen honing machines to ensure consistent quality and productivity.

Honing has minimal effect on wall thickness variation, concentricity or inner diameter straightness. Other processes precede honing when large amounts of material need to be removed or concentricity improved. Kuai Ma Steel combines drilling, gun drilling, honing and other capabilities to produce tubular components and custom tubes with industry-leading precision.

At Kuai Ma Steel, our experienced staff will help you determine which precision drilling and tube conditioning services will produce the highest quality, most cost-effective end product to meet the stringent demands of the medical, aerospace, energy and industrial sectors.
