The working principle of the deep hole honing machine is mainly based on the rotation and reciprocating motion of the honing head, and the grinding effect of the whetstone strip (or sand strip) on the surface of the inner hole of the workpiece. Here's a detailed explanation of how it works:
一. Structure and movement of honing head
head: The honing head is a key component, with one or more oilstone strips (or sand strips) installed on it. These oilstone strips are expanded in the radial direction by an expansion mechanism (there are two types: rotary type and push type), so that they are pressed against the workpiece hole wall, creating a certain contact area and pressure.
Rotation and reciprocating motion: During the processing process, the honing head can perform rotational motion and linear reciprocating motion. At the same time, the workpiece can also remain stationary, or move relative to the honing head (for example, the workpiece reciprocates while the honing head only rotates; or the workpiece only rotates while the honing head reciprocates). This compound movement mode causes the abrasive grains on the whetstone strips to form intersecting and non-repeating cutting trajectories on the surface of the inner hole of the workpiece.
二. Grinding and polishing process
Grinding action: Under the action of suitable honing fluid, the whetstone bar performs a combined movement of rotation and reciprocating feed on the surface to be processed. This movement mode allows the abrasive particles on the oilstone strips to remove the machining allowance on the inner hole surface of the workpiece, improving dimensional accuracy and geometric shape accuracy.
Polishing effect: As grinding progresses, the abrasive grains on the whetstone strips gradually wear away, the cutting force decreases, and the surface of the inner hole of the workpiece begins to be polished. This process further reduces surface roughness and improves the surface quality of the workpiece.
三. The function of honing fluid
Cooling and lubrication: Honing fluid plays a role in cooling and lubrication during the machining process, helping to reduce the heat and friction generated during the grinding process and extending the service life of the whetstone strip and workpiece.
Cleaning and chip removal: Honing fluid can also clean cutting chips and impurities on the surface of the inner hole of the workpiece, keeping the processing area clean and ensuring processing quality.
四. Processing accuracy and surface quality
Processing accuracy: Deep hole honing machine toolshave high processing accuracy and can meet strict requirements for the size, geometry and position accuracy of the inner hole of the workpiece.
To sum up, the working principle of the deep hole honing machine tool is to use the rotation and reciprocating motion of the honing head and the grinding effect of the oilstone strip on the surface of the inner hole of the workpiece to achieve the finishing of the inner hole of the workpiece. During the machining process, honing fluid plays the role of cooling, lubrication, cleaning and chip removal, which helps to improve machining accuracy and surface quality.
