Working principle of boring machine

The working principle of boring machine is that the rotation of boring tool is the main movement, and the movement of boring tool or workpiece is the feeding movement, which is used to process high-precision holes or finish the finishing of multiple holes at one time.

Long hole boring, represented by coaxial hole system of box parts, is one of the important contents of metal cutting.

Although there are still examples of boring long holes by using boring dies, guide sleeves, long boring rods supported by the back column of table milling and boring machines or manually aligning the workpiece to rotate180, in recent years, on the one hand, due to the extensive use of CNC milling and boring machines and machining centers, the coordinate positioning accuracy of various horizontal milling and boring machines and the rotary indexing accuracy of the table have been greatly improved.

Long-hole boring gradually turned around from high-efficiency working lathe 180 self-positioning boring. On the other hand, the mass production and application of ordinary or CNC gantry milling and boring machines with bed layout make turning 180 self-positioning boring by working lathe almost become a method of boring long holes on this machine.

Extended data

Boring machines are divided into horizontal boring machines, floor boring and milling machines, diamond boring machines and coordinate boring machines.

① Horizontal boring machine: the most widely used boring machine with the widest performance, which is suitable for single-piece and small-batch production and repair workshops.

(2) Floor boring machine and floor boring and milling machine: characterized in that the workpiece is fixed on the floor platform, which is suitable for processing workpieces with large size and weight and used in heavy machinery factories.

(3) Diamond boring machine: using diamond or cemented carbide tools to bore holes with high precision and small surface roughness with small feed and high cutting speed, which is mainly used for mass production.

(4) Coordinate boring machine: It has precise coordinate positioning device, which is suitable for processing holes with high precision requirements such as shape, size and hole spacing, and can also be used for marking, coordinate measurement and calibration, and used in tool workshops and small and medium-sized batch production. Other types of boring machines include vertical turret boring machines and milling machines, deep-hole boring machines and boring machines for repairing automobiles and tractors.
