### Overcoming the Challenges of Threading Hardened Parts ...

Apr 03, 2017 · The resulting Secomax CBN200 CBNtipped trapezoidal insert was designed to offer the toughness, wear resistance and long tool life the shop needed. In fact, the enhanced insert reduced threading cycle time by 33 percent, Seco says. Under normal/soft part conditions, a carbide tool would generate the ACME thread in approximately 18 passes.

Acme threads appeared sometime in the late 1800's, as an improvement on the square thread form. Square threads were the first choice for motion transfer and heavy loads. But, square threads were difficult to produce with available cutter technology. Although the square form was relatively efficient for the purposes required, it was inherently weak at [.]

### Custom Made Trapezoidal Screws and Nuts |

Trapezoidal Screws at Work. A trapezoidal thread is a moving drive thread and has to endure a high friction rate. This usually means the threaded part of the screw is selflocking and therefore has the advantage that it does not have to be secured separately in a resting position. Trapezoidal screws are used in various ways, and can be used:
