Current Process

The melamine fuse bodies are ground using a legacy hydraulically operated centerless form grinder. Decades of use have prompted customers to replace existing machines with newer versions.

Challenges

Simplify the setup process and create a consistent operation. Ensure that the OD dimensions of the melamine fuse bodies are uniform and within the allowed tolerance.

Solution

Solution: PG-9DHD Centerless Form Grinder

The PG-9DHD is equipped with an intuitive HMI that facilitates and standardizes the setup procedure. The infeed motion is executed using a servo motor for better tolerance and control. During testing, this PG-9DHD operated with a 17 second cycle time while maintaining the required tolerances of +/- 0.05”-0.2”.

  • The PG-9DHD Centerless Form Grinder is available with remote connectivity, gauging, automation interfacing, and precise positioning.
  • As demand for electric vehicles increases, fuse bodies are in higher demand requiring greater manufacturing efficiencies to meet production needs and reduce costs.
  • Depending on the part, this centerless form grinder can cut each 10” fuse body tube into 2, 3, or 4 pieces, reducing the grinding process to one step with no operator intervention and minimal maintenance.
