  2. 1. Hard Turning of Bearing Steels. Controlling residual stress and improving fatigue life

    Author : Michael Jacobson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; x-ray diffraction; bearing steel; residual stress; fatigue life; cutting conditions; hard turning;

    Abstract : 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. READ MORE

  4. 2. Characterization of White Layers induced by Hard Turning of AISI 52100 Steel

    Author : Seyed Hosseini; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; white layer; hard turning; IR-pyrometer; nano-sized grains; martensite; cutting temperature; bainite; cubic boron nitride; residual stress; retained austenite; cutting forces;

    Abstract : 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. READ MORE

  6. 4. Alternative binder hardmetals for steel turning

    Author : Lisa Toller; Susanne Norgren; Hans-Olof Andrén; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hardmetal; cemented carbide; alternative binder; steel turning; scratch testing; plastic deformation; EBSD; transformation toughening; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Abstract : 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. READ MORE

  7. 5. Cutting Edge Titanium-based CVD Hard Coatings

    Author : Linus von Fieandt; Mats Boman; Ulf Jansson; Erik Lindahl; Tommy Larsson; Henrik Pedersen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CVD; Hard coatings; Ti C; N ; TiN;

    Abstract : 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. READ MORE
