Walter Protodyn HSC thread former combines micrograin substrate with novel cutting edge geometry
The Prototyp Protodyn HSC solid carbide thread former, available from Walter GB has a micrograin substrate with a high degree of hardness and toughness, resulting in high stability. The cutting geometry ensures that all forming edges participate evenly in the forming process, resulting in even wear distribution. Its polygonal form minimises friction and heat between tool and material.
Walter GB reports that in field experiments on one formed component, the number of threads created using a Protodyn HSC thread former increased from 20,000 with a previously used tool to 90,000 – and the 90,000 threads were formed with a time saving of two hours.
On a connecting rod component, the tool life of Protodyn HSC was 300% greater than the previously used thread former, and the number of threads produced on a crankshaft increased by almost four times per tool while tool life was increased by 280% and machining time was reduced by 25%.
