Deep Hole Drilling

Honingcraft provides deep hole drilling services. Deep hole drilling is used to remove the core of a solid steel round bar to manufacture highly specialised cylindrical components with a high degree of precision. Deep hole drilling is the preferred method to machine a hole through a solid round bar billet. When engineers and manufacturing businesses need thick-walled cylindrical components to deal with high-pressure applications like in the case of thick-walled hydraulic cylinder barrels, deep hole drilling makes it possible to select from a large variety of standard steel round bars that are readily available from most steel merchants. The steel billet can then be drilled to make a hole through the round bar.

Honingcraft’s machines can manufacture parts from round bars of 600 millimetres in diameter and four metres long. Honingcraft also provides the steel round bar from a trusted network of steel merchants to expand its own stock holding of precision manufacturing steel.

The main uses for such custom cylindrical products are ultra high-pressure hydraulic cylinder barrels, conveyor rollers and dynamometer rolls.

Deep hole drilling projects are complemented by Honingcraft’s high precision honing department which can improve the surface finish of the inside diameter to a H8 tolerance.
