The horizontal honing machine has a long working stroke and is suitable for honing deep holes, with a depth of up to 3000 millimeters; Horizontal honing machines are mainly used for workpieces that require high precision but have larger and deeper apertures, such as hydraulic cylinders.
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. New honing machines often use hydraulic expansion and contraction honing heads. 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.
The spindle working stroke of a vertical honing machine is relatively short, suitable for honing cylinder and box holes, etc. The vertical honing machine mainly processes parts with high precision requirements such as automotive connecting rods, directional valves, oil pump nozzles, 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.
Vertical honing machines are mainly used for honing engine cylinder block holes, cylinder liner holes, and other precision holes. The spindle rotation and feed of the vertical honing machine adopt stepless speed change; The spindle box can easily move vertically and horizontally; The workbench can move longitudinally and clamp the cylinder block.
