Lenham - LM 800 flight forming machine

Continuous spiral flighting machine for manufacturing industrial screws.
Helicoid flighting is formed by passing a metal strip through conical rolls under pressure.

max strip width: 200 mm
max strip thickness: 11 mm
left hand or right hand spiral direction
optimum roll speed: 80 rpm
coil capacity: 5 tons
Weight of machine: 12 tons
power: 75 HP

Including roll grinding attachment: permits the re-grinding of the conical rolls without removing them from the machine.
Including hydraulic guillotines: suitable for cutting all flights.

Standard pitch: outer dia dimension is equal to pitch dimension
Short pitch: pitch dimension is less than outer dia dimension
Long pitch: pitch dimension is greater than outer dia dimension
Ribbon flight: enlarged inner slide using narrow raw material
Cupped flight: flighting blade not perpendicular to center shaft
Stainless steel: flighting can be rolled but range is limited by the greater hardness of the raw material
