Round insert for heavy duty roughing
- April 1, 2014
Large chip build-up is a common problem when turning the inner profile of a railroad wheel, with the chips often failing to break as desired. The new round insert addresses these chip control problems, claims Walter.
Field tests at wheel manufacturers have shown that this new Walter insert provides up to 40 percent longer tool life.
The key innovation is the insert's geometry, featuring specially formed chip dimples for ideal chip formation, facilitating chip breaking in the required area. This new round insert benefits from Walter's proven Tiger·tec Silver coating which enhances cutting speed, reliability and tool life.
The inserts are available in four different grades: three for steel and one for cast iron machining. Insert diameter selection ranges from 10 to 32 mm. This combination of coating and geometry, with its specially designed chip breaker and strong cutting edge for process reliability in heavy and interrupted cuts, boosts the productivity of heavy-duty roughing operations, such as railway vehicle manufacturing, generator and turbine manufacturing, and forged components in general.
In addition, Walter Capto turning toolholders can be used with the HU6. This interface enables quick tool changes and easily handles the transfer of large forces.
