Profile and Surface Roughness
This type of measurement, which should happen before roll regrinding, will give an exact measurement for visual representation of wear by either normal or abnormal causes. If the wear is abnormal or uneven, this test will effectively identify the wear and assist you in detecting the cause of such wear.
TIR and Out-of-Balance
Vibration problems are a machine builder or operator’s worst nightmare. With our advanced measuring instruments and balancing machine technology, our specialists will detect the cause of your vibration problems.
Hardness and Chill Depth
Chill depth diminishes every time a roll is reground. It is extremely hard to identify the amount of chill left if accurate records are not kept. At SHW, our Vickers testing unit will give the most accurate hardness measurements possible.
This test, can detect uneven temperature profiles that cause an uneven paper profile.
Dynamic and Static Variable Crown Roll Testing
Variable Crown Roll testing is crucial. SHW performs both static and dynamic tests with our state of the art test stand. This test stand brings the oil to the proper temperature and viscosity before testing. This ensures that the roll test will simulate the actual operation of the roll to provide extremely accurate results before installation at the mill.
