The CNC deep-hole powerful honing machine is a specialized machine tool designed for honing and polishing deep-hole components. It is primarily used for the finish machining of internal bores in precision parts, making it an ideal high-precision, high-efficiency equipment for deep-hole machining. After precision honing, the surface roughness of the workpiece bore can be as low as Ra ≤ 0.2 µm, the roundness error is ≤ 0.03 mm, and the bore diameter accuracy reaches IT7 grade or better.
This machine tool primarily features a workpiece-fixing, honing-head-rotating-and-reciprocating structure; it is suitable for deep-hole honing of various workpieces and is particularly well-suited for non-rotational workpieces, such as precision tubular components like hydraulic cylinders and pneumatic cylinders, as well as square-shaped workpieces and workpieces with shafts or flanges welded to their outer surfaces. The workpiece is supported by V-blocks and clamped using a chain-lock mechanism, with centering achieved by adjusting the V-blocks and then securing the clamp.
This machine tool can be programmed to automatically perform the honing process, with settings for controlling honing time, the number of reciprocating strokes, and honing stroke length. It is suitable for both batch production and single-piece repair applications. The machine is equipped with a Delta control system from Taiwan and features a touch-screen HMI. Customized variants of this model can be provided according to customer requirements to meet diverse deep-hole machining needs. Drawing on advanced domestic and international honing technologies, the machine is designed to deliver timed, location-specific, and volume-controlled honing, thereby replacing outdated conventional honing machines. With the advancement of high-performance abrasives and automated honing equipment, the application of honing will continue to expand significantly.
