When using a roller cutter on tubing, why must care be taken not to cut too quickly?

When using a roller cutter on tubing, it is important to take care not to cut too quickly because rapid cutting can lead to the tube ends being compressed. When cutting occurs at an excessive speed, the pressure applied may exceed the material's ability to flex properly, resulting in deformation at the ends of the tube. This can create a situation where the tubing does not seal properly when connected to fittings, potentially leading to leaks or compromised structural integrity.

Controlling the speed of cutting allows for a more uniform, clean cut that preserves the original shape of the tubing, ensuring better fitting and performance in its intended application. The careful approach helps prevent unwanted damage to the tubing, contributing to an overall cleaner and more effective cutting process.
