AZ31B magnesium alloy is a widely used magnesium alloy due to its high strength-to-weight ratio, good corrosion resistance, and excellent machinability. It is commonly used in the aerospace, automotive, and electronics industries.

Do you know the chip removal method for deep hole drilling

When the precision requirements for deep hole machining are high, internal hole turning is also necessary after drilling, mainly to improve the size and geometric accuracy of the hole and reduce the surface roughness value.

Deep hole turning is different from general turning. By installing a deep hole boring head on the drill rod, rough and fine turning can be performed. The boring head and drill rod are connected by threads, and the structure of the boring head.

To prevent deformation and vibration of the tool holder due to excessive overhang, there are guide blocks before and after the boring head. The guide blocks can be made of wood, copper, cast iron, hard alloy, or other materials. Before drilling, a guide hole should be machined to coincide with the axis of rotation.

During precision machining, the surface roughness of the guide hole should reach Ra3.2m, and the depth of the guide hole should be 0.6D1.5D. The size of the boring tool is adjusted using the tool block
