Inca Breaks into Aerospace Sector

Following the installation of a Mazak VTC-300C-II travelling column vertical machining centre, Chartham near Canterbury-based Inca Geometric has been able to secure its first aerospace contract of 30 initial components with a totally new customer.

The initial batch of 30 control housing components involved machining every facet from a solid aluminium tooling plate. The Inca method overcame previous problems when the customer produced the parts from castings. Among the problems experienced from use of cast material was a particular difficulty in maintaining a constant depth and form on special sealing grooves in the joint face.

Managing director of Inca Mike Cain explains: "We were approached to quote for machining the castings but the Mazak VTC gave us the opportunity to put forward a very competitive alternative process for complete machining from solid. This also gave us the ideal opening to break into a new sector from which we can expect further contracts."

The Mazak set up involved A and B fixturing to create a pendulum-based process. Said Mr Cain: "This meant we were loading during machining and were able to complete the process in a relatively quick cycle time."

Each control housing required face and profile milling, slotting, drilling and engraving of legends which were previously cast onto the control panel face. On the reverse side, extensive pocketing and profiling of the seal groove was carried out.
