asiakas-tk-vilmet-sandvik

Sandvik group’s Mining and Rock Technology business area is the world’s leading supplier of excavation and drilling equipment, drilling machinery, and related services in the mining and contracting industry. Applications include above- and underground drilling, mechanic removal, crushing and screening of rocks, loading and transportation, rock construction, excavation, and crushing and breaking.
TK-Vilmet is among Sandvik’s main subcontractors. The company’s products include welded and machined frame and boom structures of rock drilling equipment.

A good example of the significance of this cooperation is the quality system, which was developed partly to enhance the quality of Sandvik’s welded steel structures. The delivery process developed as part of the project was completed in cooperation with the supplier network, which also included TK-Vilmet. TK-Vilmet initiated the certification process of its own welding quality system in order for it to meet the requirements of the SFS-EN ISO 3834-2 standard. For the welders of the machine shop, the benefits of the quality system are clear, as the good quality of the welding contributes significantly to the durability of the end product.
