Jan is a saw consultant with experience in bimetal saws, their heat treatment and optimising their performance. Wear of saw teeth, fatigue of saw backing, influence of cutting lubricants, residual stresses in saws, noise at sawing are some of some of the subjects of his studies.
He has developed a tool life formula, necessary for optimising sawing. He has also developed theories for economic optimisation of sawing. Among the customers there are a Swedish research institute, ALO Center, saw users and saw producers. He is also an often used lecturer in band sawing.
Do not hesitate to contact Jan if you have questions in sawing.
