Current Process

Super-abrasive grinding wheels require faster speeds to run effectively. Main machine spindles can have fixed speeds, limiting their ability to use CBN or Diamond grinding wheels. A fixed speed can cause belt squeal and added stress on the spindle. When the wheel stops, inertia allows it to continue spinning for minutes, especially with heavier wheels, delaying the start of the next job.

Challenges

Dynamic spindle speed adjustment enabling work wheel rotation at higher speeds using super-abrasive grinding wheels. Provide the upgrade in real-time without having to ship the machine back to the factory for an upgrade.

Solution

Solution: Work wheel variable speed control inverter. Available on Glebar's GT-9AC and TF-9DHD.

 

Allows the operator to vary the work wheel RPM to optimize cutting action. Ramp up and ramp down time is controlled for a smoother start and faster stopping. The inverter upgrade kit eliminates the need to ship the machine back to Glebar.

 

  • In some cases using a super-abrasive wheel can generate 2x longer uptime than conventional abrasives reducing the downtime between setups.
  • Super-abrasive wheels run longer between dressing operations increasing uptime.
  • Using a variable speed work wheel spindle allows manufacturers to take advantage of the super-abrasive technology.
  • A Glebar technician can install the upgrade kit at the customer site reducing lost production time.

GT-9AC

The GT-9AC is designed to grind medical guidewires with multiple tapers, paddles, and even parabolic shapes, with the ability to update the linear position of the wire every 0.00025" (0.006 mm) at grinding speeds superior to traditional centerless grinding.
