Properly hardening precision parts in a timely matter with a high level of accuracy is always a tall order. Whether you are dealing with rotationally symmetrical components, gears for powertrain transmissions, transmission parts for industry, aviation or agriculture; WICKERT has you covered. We have the solutions and process knowhow to help you solve complex challenges and increase throughput.
With our systems, components are heated to hardening temperature and are held down by tool inserts; thus maintaining their flatness and precise concentricity. In using a mandrel with WICKERT, the inner diameter of the component is effectively shrunk onto the mandrel center. This generates a defined inner diameter, ensures cylindricity, and thus eliminates the need for expensive hard machining.
We can customize furnace times, component sizes and geometrical properties to your individual needs.
We can meet almost any customer requirement to produce a cost-efficient system.
In regards to mandrels, there are typically two types used in hardening: a fixed mandrel and expanding mandrel. A fixed mandrel is a cylinder with static dimensions to hold parts in place, has less tooling costs and can be designed with teeth if required. Expanding mandrels on the other hand, use several segments along with an expanding cone moving on a block, to move the coordinated segments to a defined diameter and hold the part in place. During this process, parts are held in position with hydraulic pressure during the shrinking of the component.
