    Polishing of Hard Machining Semiconductor Materials Made of Silicon Carbide
    (Wydawnictwo Politechniki Łódzkiej ; Katedra Dynamiki Maszyn - Wydział Mechaniczny Politechniki Łódzkiej, 2011) Gołąbczak, Marcin
    In the paper the application of silicon carbide (SiC) in electronics especially for production of p-i-n diodes have been shown. Also the technology of honing process of samples made of silicon carbide using grinding, lapping and polishing method has been presented. Finally the process of machining and the stand for surface preparation, selected investigation results concerning assessment of geometrical microstructure and morphology of SiC samples surface layer after machining process have been depicted.

    The Effect of Grinding in Titanium Alloy Deformation.
    (Lodz University of Technology. Faculty of Mechanical Engineering. Department Division of Dynamics., 2013) Wójcik, Ryszard
    The machining of titanium alloys is relatively elaborate process which carries out large values of cutting forces and torques. For these reasons it is essential to impose specific requirements for tools, cooling system and lubrication. The present paper deals with examination of grinding process of titanium alloy with grinding wheels made of chromic electrocorundum and microcorundum. During investigation flat areas were grinded with the participation of minimum quantity lubrication and compressed air. On the basis of tests degree of the deformation and the parameter roughness Ra were examined.

    Damage of the Surface Layer Gears in Grinding Process.
    (Lodz University of Technology. Faculty of Mechanical Engineering. Department Division of Dynamics., 2013) Wójcik, Ryszard; Wlazło, Jakub
    The influence of the grinding process on the condition of the surface layer (SL) obtained by the treatment of the gear with grinding wheels Al2O3, CBN, GF, SG, alloy steels with different parameters of the grinding process and the type of cooling liquid – lubricant (CLL). The stress distribution at the surface layer, structural changes, secondary hardening, forgiveness SL and drastic damage–microcracs have been presented in comparative studies.

    Grinding Process Results with Oil Mist.
    (Lodz University of Technology. Faculty of Mechanical Engineering. Department Division of Dynamics., 2016) Wójcik, Ryszard; Wejman, Przemysław
    The paper presents a study of the process of grinding titanium grinding wheels with mikrokorundu, sanding at surfaces involving liquid - cooling lubricants using MQL, used machining fluid - propylene glycol and other liquids business dedicated to the administration with a minimum expenditure of the grinding zone. Were studied component of cutting forces - and tangent parameter.

    The Analysis of the Cutting Forces and Surface Layer Stereometry in the Grinding Process of Abrasion-Resisting Materials
    (Lodz University of Technology. Faculty of Mechanical Engineering. Department Division of Dynamics., 2016) Wójcik, Ryszard; Grdulska, Anna; Rosik, Radosław; Wejman, Przemysław
    The article presents the investigation of the grinding process of flat samples made of materials that meet requirements of the lowest abrasibility, which belong to difficult to machine materials. Research enclosed measurement of cutting forces and surface layer stereometry during grinding without using cutting fluid. The tests were carried out with the aid of new generation grinding wheel, Quantum.
