1. Hard Turning of Bearing Steels. Controlling residual stress and improving fatigue life
Sammanfattning : There are many different precision mechanical components such as bearings, fuel injectors, gears and hydraulic components, which are made of hardened steels, and have to be machined to a high degree of precision. Traditionally these components are being ground. LÄS MER
2. Characterization of White Layers induced by Hard Turning of AISI 52100 Steel
Sammanfattning : Hard turning is a machining process applied to metallic materials with hardness above 45 HRC. The process offers high production flexibility and sustainable manufacturing since it allows performing both rough and finishing machining of complex geometries in one single setup. LÄS MER
3. Surface integrity generated by hard turning
Sammanfattning : .... LÄS MER
4. Alternative binder hardmetals for steel turning
Sammanfattning : The goal of this work is to understand how the wear and deformation mechanisms of hardmetalinserts change when the cobalt binder phase is replaced with a dierent metal or analloy. The focus is on inserts for steel turning. The work presented in this licentiate thesisconsists of the rst steps. LÄS MER
5. Cutting Edge Titanium-based CVD Hard Coatings
Sammanfattning : Modern tools for metal cutting applications, such as turning or milling, are typically improved with a thin protective coating. Despite being only a few microns thick, the coating can increase the lifetime of the tool by more than 100 times compared to an uncoated tool. Two different types of techniques are normally used to deposit the coatings, i. LÄS MER
