Technical Field

The invention relates to the technical field of horizontal boring and milling equipment, and in particular to a special integrated horizontal boring and milling machine.

Background technique

Boring and milling machines are a type of processing tool commonly used in the processing industry. They combine the functions of boring machines and milling machines in one, making processing more efficient and accurate, greatly improving product quality and labor efficiency. Boring and milling machines combine the processing methods of boring machines and milling machines, and are mainly used for boring holes and milling planes. According to the degree of automation, they are divided into traditional boring and milling machines, precision boring and milling machines, and CNC boring and milling machines; according to the layout form, they are divided into vertical boring and milling machines, horizontal boring and milling machines, and floor-standing boring and milling machines. Horizontal means that the tool axis is perpendicular to the processing plane. Boring and milling machines integrate boring and milling on the same machine tool, that is, this machine tool has both boring cutters and milling cutters.

When boring and milling the workpiece, a large amount of metal debris will be generated. If it is not cleaned in time, the boring and milling accuracy will be affected. The accumulation of waste on the workpiece surface or around the tool will cause uneven contact between the tool and the workpiece, affecting the processing quality and accuracy. In addition, the accumulation of waste may also cause accelerated tool wear, affecting the processing efficiency and cost of boring and milling. When boring pins on the workpiece, general boring tools are of a single size and cannot quickly process boring holes of different sizes on the workpiece. Different boring tools need to be replaced, which makes the processing efficiency easily affected to a certain extent. Therefore, it is necessary to propose a horizontal milling and boring machine to solve the above problems.
