Simple, Fast and Consistent Results, Every time!

The cutting tool edge-prep (honing) or polishing process consists of only a couple of fast easy steps:

  • Select Tool to process - end-mills, drills, taps, carbide inserts etc....
  • Load tools in the Tool Holders - simple loading, bayonet or set screw collets
  • Place holders in machine - simple, one spring release mechanism
  • Select correct Process Media - edge-prep, or polishing media
  • Program process time and press start
  • Unload Tools - your done in as little as 2 minutes!! (depending on material)
  • Optionally Inspect with our non-destructive metrology equipment.

Cutting Tool Edge-Prep - Honing

The edge-prepping, or honing, of a cutting tool involves radiusing of the tool edge to remove the sharpness of the edge. Drag Finishing technology for this purpose has proven to be one of the most cost & time efficient ways of accomplishing this. Results have shown that tool life increases of up to 300% or more are easily achievable, with a noted reduction of cycle times..

In this process, multiple tools are fixtured into the tool holders to ensure the proper introduction into the process media. Machine parameters, such as direction of rotation, speed and process time are set and the machine is placed into operation. At the end of a cycle, parts are removed from the fixtures, and the next batch prepared for processing.

The degree of hone desired will vary based on the material of the tool, and the end use of the tool. Varying degrees of hone can be also be obtained by proper selection of process media.

Cutting Tool Polishing

Drag Finishing Technology has also proven to be another cost & time effective process to polish cutting tools. Results have proven that a properly polished cutting tool, whether it be a non-coated, or coated tool, allows the tool to run cooler, allowing for faster feed rates, thus reduced cycle times for the end user. Additional benefits include better chip removal due to the highly polished "swarfs".

As with edge-prep procedures in drag finishing, proper media selection, proper introduction of the part into the process media, direction of rotation, speed and time cycle all play an important part in the end results. Proper media selection will be based on the material of the tool, and whether it is coated, or non-coated. Testing has proven that polishing of coated tools helps to remove the tiny droplets of coating that are inherent in the coating process. This removal of the droplets reduces friction, and the possibility of chipping. It is found that in the removal of the coating droplets, a small cavity is formed which helps to provide a reservoir for cutting fluids used in the machining process, thus resulting in an obvious benefit.

Carbide Inserts Edge-Prep - Honing

Cutting Tool Inserts, such as the carbide inserts shown below are ideal candidates for edge honing with the drag finishing process. The inserts can can fixtured easily with multiple inserts fitting on each simple fixture. Our work holders will also accept multiple fixtures thus allowing for large batches of inserts to be processed at once.
