Centerless Grinding Process Improves Fuel Injection Valve Development

Single disc roller application reduces lead times and tooling costs; supports fast track development projects and long-term production runs.

Glebar (Ramsey, NJ) has developed a centerless grinding process on its GT 610 CNC for automotive manufacturers that expedites the development process of fuel injector nozzle valves, leading to reduced tooling costs, lower inventory levels, and quicker integration of new technology for prototyping or proof of concept for a new component.

The centerless grinding development process can sometimes incorporate up to 20 critical dimensions, all of which need to be centerless ground. Glebar’s process increases the efficiency of the centerless grinding prototyping process by using a single disk CVD dress roller as part of its grinding system with the full CNC work wheel dressing. 

Additional features include:

  • A CNC dressing system that has sub-micron positional accuracy, which allows intricate forms to be dressed into the work wheel.
  • A single disk roller, which allows the end user to generate a multitude of profiles using one roller. The P4K non-contact measurement system, which makes adjustments feeding back radii, steps, diameters and angle measurement to automatically adjust the wheel shape.
  • An off-line gauge that eliminates trace measurement systems as well as optical comparators. 
  • Interface software that is custom generated internally to feedback to the machine for infinite wheel shapes.

The Glebar GT 610 CNC will be exhibited at the upcoming International Manufacturing Technology Show in Chicago beginning on September 12, 2016, Booth #N7317.
