Advantages and disadvantages of the two-roller bending machine

Release time:2014-06-27 09:08:35 Source of the article:qyjljc Number of clicks:3067

  Advantages of the two-roller bending machine:

  1. The processing speed of the two-roll bending machine is fast;

  2. The high-precision molding material of the two-roll bending machine in one stroke;

  3. Even if the slab is processed through punching, slitting, undulating molding, etc., it will not cause cracking and irregular warping;

  4. When the two-roller rolling machine rolls the slab, it will not wrinkle the slab and will not cause scratches on the surface of the workpiece;

  5. If the reduction of the roller of the two-roller is large, even if the spacing of the two rollers changes and the diameter of the workpiece does not change, the accuracy of the equipment is not very high. It is a simple device and so on.

  The disadvantages of the two-roller bending machine are:

  The two-roll bending machine is not suitable for multi-variety small-volume production because the two-roll bending machine requires a guide roller for each change in the diameter of the workpiece.
