Bore finishing with tight tolerances and high precision is typically achieved through a combination of multi-step processes, such as drilling, reaming, boring, burnishing and rough honing. Each manufacturing process step necessitates a tool change and distinct cycle, which increases total takt time and introduces characteristics that may complicate the subsequent steps.
The new Engis Hybrid solution streamlines the workflow by integrating single-pass bore finishing with a multi-stroke honing process in a single machine, thereby reducing the number of required steps. These integrated technologies allow users to achieve exceptional precision when finishing bored components. It also produces sharper, burr-free corners on cross holes and metering edges within the part.
This new model's custom multi-stroke head uses a set of expanding honing stones to semi-finish bores. The programmable expansion amount is verified by a subsequent gauge station, allowing the machine controls to automatically compensate for tool wear. Additionally, the unique system incorporates a separate column with three single-pass spindles for the final finishing process.
The components are loaded into part holding fixtures arranged around a rotary index table, maximizing productivity. This setup allows all operations to occur simultaneously, producing a complete finished part with each cycle. Operators can load and unload the parts manually or use a custom robotic automation package.
This single-step system, designed for high-volume production of hydraulic cartridge valves and servo valve bushings, can finish hundreds of thousands of bores annually - transforming rough bores into finished products and greatly simplify the spool matching process.
