Continuous, Conventional Helicoid Flighting

Lenham Flight-Forming Machines produce Conventional continuous helicoid flighting with a smooth, even taper from the inner to the outer edge. The thickness at the outer edge is typically 50% of the original raw material thickness.

The following types of conventional helicoid flighting can be produced on all Lenham Flight Machines:

Spiral direction	Left hand or right hand
Standard Pitch	Where the outer diameter dimension is equal to the pitch dimension
Short Pitch	Where the pitch dimension is less than the outer diameter dimension
Long Pitch	Where the pitch dimension exceeds the outer diameter dimension
Ribbon Flight	Where flighting has a large inner diameter using a narrow width of raw material
Cupped Flight	Where the working surface of the flighting is angled at up to 30 degrees from perpendicular
Stainless Flight	Stainless flighting as per grades recommended by Lenham can be rolled on Lenham machines although the scope and range of sizes are limited
