What is the working principle of Precision Deep Hole Honing Machine

Precision Deep Hole Honing Machine is a professional equipment used for processing high-precision, high-surface quality deep holes. Its working principle is based on the honing process. Honing is a processing method that combines grinding and polishing. With the help of the rotation and reciprocating motion of the honing head in the hole, the precision processing of the hole wall is achieved.

The honing head is the core of the equipment and is usually equipped with multiple grinding bars. When working, the honing head rotates along the hole axis under the drive of the spindle and performs reciprocating linear motion at the same time. The superposition of these two movements allows the grinding bars to form a cross grinding track on the hole wall, achieving uniform material removal and surface polishing. The grinding bars contact the hole wall, grinding away tiny unevenness and processing allowances, and reciprocating motion is used for polishing to improve the surface finish and geometric accuracy of the hole wall.

The grinding bars of the honing head can be expanded radially by mechanical or hydraulic means to adjust the grinding pressure and control the processing size, with an accuracy of up to micron level. During honing, coolant is injected into the processing area to play a role in cooling, lubricating and chip removal, preventing the workpiece and grinding bar from overheating, taking away the debris and ensuring the processing quality. Modern Precision Deep Hole Honing Machines are mostly equipped with CNC systems, which can automatically control the parameters such as the rotation speed, reciprocating frequency, and grinding bar pressure of the honing head to achieve high-precision and high-efficiency automated processing. In short, precision deep hole honing machines can improve multiple precision indicators of holes at the same time with their unique movement mode and processing function, and are widely used in many high-precision processing fields.
