A webinar about Valmet Doctoring Services Agreements was held on October 21st, 2020 and is available HERE.
A Valmet Doctoring Services Agreement is a partnership program between the mill and Valmet to improve overall performance of the machine, reduce downtime and maintenance costs through improved roll doctoring. The program includes doctoring audits, recommendations for improvements, blades, storage and blade handling equipment to reduce safety incidents, optimize blade performance and reduce the total cost of ownership.
The program also includes inventory managment which can be integrated with mill ERP systems. We organize the entire doctor blade program from ordering, inventory and installation.
