type 1: NC Top Roll Variable Geometry Plate Rolls PRT
PRT 3-roll bending machines designed, manufactured and marketed by BIT deliver performance equivalent to that obtained with the more expensive 4-roll plate bending rolls and are therefore ideal for medium-heavy duty machining.
- Bending Thickness: 50-200mm
- Pre-bending Thickness: 40-160mm
- Bending Width: 1000-10000mm
type 2: 3 Roll Variable Geometry Bending Rolls PRV
The technological and innovative PRV is a 3-roll variable geometry bending machine particularly suitable for bending medium-large thickness sheets. Accuracy, speed, and great bending performance, both in bending and pre-bending, make PRV unique in its kind.
- Bending Thickness: 60-120mm
- Pre-bending Thickness: 50-100mm
- Bending Width: 3200-4000mm
type 3: Initial Pinch Plate Roll PRA
These PRA small initial pinch 3 roll steel plate rolling machines are designed for small part bending with low operation cost, they are made for bending and rolling metal sheets or plates into cones and other cylindrical shapes. They feature robust cast iron frames, chain and gear-driven drive systems, and electric motors with a magnetic brake which eliminates drifting. All three rolls are hydraulic-driven, hardened, and made of high-grade alloy steel.
- Bending Thickness: 2-6mm
- Pre-bending Thickness:2-6mm
- Bending Width: 1000-2000mm
type 4: 3 Roll Double Pinch Plate Bending Machine PRD
PRD 3 roll plate bending machines are reliable and tested hydraulic bending machines, with three driving rollers with hydraulic pinching that guarantee a precise and constant drag of the material. The point of contact of the side roll with the sheet metal takes place in a shorter space thanks to a narrower center distance; this allows working with very small diameters reducing further the flat edges.
- Bending Thickness: 4-30mm
- Pre-bending Thickness: 3.5-25mm
- Roller’s Working Length: 2000-3000mm
type 5: 3-Roll Pyramid Roll Bending Machin PRS
PRS Pyramid Roll Bending Machines are designed to cater to the basic requirements of bending & forming metal plates, PRS plate rollers belong to 3-roll symmetrical mechanical structures.
PRS plate rolling machine does well in compact structure, easy operation, and convenient maintenance.
- Bending Thickness: 4-40mm
- Bending Width: 1500-3000mm
- Top Roller Dia.: 150-500mm
