We have 2 sets of hydraulic cold drawing bench and 3 sets of chain cold drawing bench that ensure us to manufacture cold drawn tubes with OD range from 60mm to 325mm and wall thickness of 50mm max.

Deep hole boring can be used for both deep hole boring and skiving&roller burnishing. Deep hole robing is actually a procedure before honing or skiving&roller burnishing, and this procedure ensures the concentricity of bore thus always leads to perfect bore of tubes after honing or skiving&roller burnishing.
