Beta 3 |
| THREE ROLL, DOUBLE PINCH |
| with brute power and built to last! |
|
| The Beta 3 is designed to roll steel above 25mm / 1.000" thick with yield strength of 350N/mm² / 50,000 psi to 1.4 the top roll |
| diameter of the machine. COMAL believes that to assure positive results of the function and durability of the roll when it is |
| purchased with the intention of rolling such thick materials day in and day out, meaning 16+ hours shifts, the slide and block |
| system is the answer. COMAL accepts the fact that an orbital path system for the bending rolls' movement with linkage style |
| mechanisms may be used (as in our Kappa design). The fact remains that line contact bearings are inferior, for wear |
| and load carrying capacity, when compared with that of large surface area contact bearings. |
|
| Comal is also ready to provide our customers with a choice. If you request, we will offer you a Kappa 3 with the orbital motion system having the same |
| capacities of the Beta 3 machines listed below, at the lower price. |
|
| The capacities you read at the end of this page are TRUE RATINGS of the machines. They are clearly specified at 50,000 psi |
| or 350 N/mm² material YIELD STRENGTH and at which diameter the machine will perform at the specified thickness on |
| its FULL ROLLS' LENGTH. Also presented are the capacities at 36,000 psi/ 250N/mm² for comparison with other suppliers' |
| machines, which may be rated at this yield strength and 3 to 5 times the top roll diameter! |
| Cone bending on these machines will require you to reduce the machine capacity by 25% on thickness and length. |
| For more information concerning cone bending contact our sales engineers. |
