Linear boring machines mainly include the following types:
Horizontal boring machine: This is the most widely used type of boring machine, mainly used for hole processing, the boring accuracy can reach IT7, and the surface roughness Ra value is 1.6-0.8um. The boring axis of the horizontal boring machine is arranged horizontally and axially fed, the spindle box moves vertically along the front column guide rail, and the worktable moves vertically or horizontally for boring processing. This machine tool is suitable for single-piece small batch production and repair workshops.
Coordinate boring machine: This is a high-precision machine tool with a precise coordinate positioning device. Coordinate boring machines can be divided into single-column coordinate boring machines, double-column coordinate boring machines and horizontal coordinate boring machines. Single-column coordinate boring machines are suitable for processing precision holes of plate parts, but have poor rigidity; double-column coordinate boring machines have good rigidity and are suitable for large coordinate boring machines; horizontal coordinate boring machines have high processing accuracy and are suitable for high-precision hole system processing.
Diamond boring machine: Use diamond or carbide tools to process with small feed and high cutting speed, with high processing size accuracy (IT6) and surface roughness up to 0.2 microns. This boring machine is suitable for precision boring in mass production.
Deep hole drilling and boring machine: With strong rigidity and high precision, it is suitable for various deep hole processing processes. The spindle speed range of deep hole drilling and boring machine is wide, and the feed system is driven by AC servo motor, which is suitable for drilling, small diameter boring and large diameter trepanning processing.
These types of linear boring machines each have their own characteristics and applicable range. Choosing a suitable boring machine can improve processing efficiency and accuracy.
