Grooving a Threaded Mill Roll

0:28 clip · shop-floor footage · Huamin Tools

A threaded roll carries a groove that has to repeat at a fixed pitch along the body. This clip shows that grooving pass, with the insert working a long, repeating cut.

What the clip shows

  • Repeating groove along the roll body
  • CBN insert in a long, interrupted sequence
  • Pitch consistency visible across the body

Why this insert suits the cut

A repeating groove gives the insert no rest. Each entry is a small impact, and over a full body those impacts decide insert life more than the cutting speed does.

Where this part is used

Threaded rolls are used in piercing and speciality mills. A pitch that drifts along the body produces out-of-spec product for the whole campaign.

What to send with an inquiry

  • Pitch, groove count and body length
  • Whether the groove is cut in one pass
  • Insert life currently achieved per body

Send the drawing, material and current tool problem. We will recommend an insert direction for the operation.
