Honing machines are mainly used in manufacturing industries such as automobiles, tractors, hydraulic components, bearings, and aviation to hone the holes of workpieces. They are grinders that use honing heads to hone the surface of workpieces for precision machining. Honing machines are divided into two types: horizontal and vertical.
The horizontal honing machine has a long working stroke and is suitable for honing deep holes, with a depth of up to 3000 millimeters. The horizontally placed honing head does not rotate, but only performs axial reciprocating motion. The workpiece is driven to rotate by the main shaft, and there is a center frame supporting the workpiece and a guide frame supporting the honing rod in the middle of the bed. During the machining process, the oil stone of the honing head is fed radially under the action of the expansion and contraction mechanism, gradually processing the workpiece to the required size.
The spindle of a vertical honing machine has a short working stroke, which is suitable for honing cylinder and box holes, etc. The honing head embedded with oil stones is driven to rotate by a vertically arranged spindle, while performing vertical reciprocating feed motion under the drive of a hydraulic device.
Honing machines are mostly semi-automatic, often equipped with automatic measuring devices, and can also be incorporated into automatic production lines. In addition to honing machines for machining holes, there are also cylindrical honing machines, bearing raceway honing machines, flat honing machines, and curved honing machines for machining other surfaces. New honing machines often use hydraulic expansion and contraction honing heads.
