Super-abrasives replace honing in bores
Having proved itself to be cost-effective for almost all bore finishing applications, single-pass super-abrasive bore finishing technology is rapidly superseding conventional honing, said Engis.
Having proved itself to be cost-effective for almost all bore finishing applications, single-pass super-abrasive bore finishing technology is rapidly superseding conventional honing for finishing internal diameter bores and work-piece materials, said Engis Advantages of the process include the following

Electro discharge grinder machines PCD tooling
Designed for use in PCD toolmaking applications an electro discharge grinding machine is quick to set up and program and the machine can accept most tool types.
* Lower labour costs - through automated finishing.
* Lower cost per hole - through long tool life.
* Improved bore quality.
* Reduced rejects.
* Higher production rates.
However, to achieve these results the most advanced bore finishing tooling and work holding is required.
Engis manufactures diamond and cubic boron nitride (CBN) tooling packages under ISO9002 certified quality control systems, ensuring its products achieve the highest level of quality.
Using Engis tooling, extremely tight tolerances can be held reliably and consistently in a production environment, reducing overall cost per finished piece, said the company.
Engis diamond-plated and super-abrasive finishing tools are capable, in standard, blind and semi-blind bores, of achieving bore geometries to within 0.000020in.
Engis tools use plated diamonds, so they cut cooler, maintaining their size and achieving extremely long tool life - so reducing the cost per finished item.
The company also offers standard and custom tooling packages with options including spring-loaded tooling, coolant-through-tool designs and special tooling for bore-to-datum concentricity.
* Fixture design - among the most critical features in any system design is the work holding fixture.
Engis specialises in custom fixture design, and each application is carefully reviewed for simplicity, ease of use, versatility and fast-changeover with options including fixed or floating solutions.
At the company's dedicated Bore Finishing Process Development Laboratories customers can obtain valuable technical support, working side-by-side with Engis engineers to test and improve processes.
For example.
* Tooling packages are tested and refined for process optimisation.
* Tool holders and fixturing packages are tested.
* Prototype parts are run at various cycle rates.
Each process is studied, step by step, including stock removal rates, bore geometry requirements and surface finish, to ensure customers achieve their engineering objectives.
