Fresh leaf samples were finely ground in liquid nitrogen using marbles and a multisample tissue grinding machine (Shanghai Jingxin Industrial Development Co., Ltd., Shanghai, China). Then, 400 mg of powder was soaked in 1 mL of extraction buffer and mixed with 8 mL of extraction buffer in a 15-mL Eppendorf tube and sonicated for 20 min at room ...

An experimental investigation was carried out to study the effect of variation in Barkhausen noise (BN) analysis parameters (magnetizing voltage and excitation frequency) for assessment of microhardness profile upon surface grinding. A varying amount of surface damage was induced in the ground samples by changing the downfeed during grinding.

Applying a bearing preload of machine tool spindle produces positive effects, including increased stiffness, rotation noise reduction, increase in shaft precision, position adjustment during operation, and prevention of rolling element resonance and rotating slip, along with a significant extension of the bearing lifespan.

The development of desktop milling, turning, and grinding machines have been widely reported in the literature (Okazaki et al., 2005, Subrahmanian and Ehmann, 2002, Walk and Aurich, 2014). An interesting further development of the desktop machine concept is the addition of multi-functionality to the machine tool.

Camshaft grinding uses an OD cylindrical-grinding machine to grind non-round cam lobes. This is a complex grinding process, characterized by transient and non-constant geometry and kinematics [54] . For example, the surge in material-removal rate on a cam-lobe flank can cause grinding-temperature surges and localized grinding burn.

Reishauer looks back on a 200-year long, eventful but successful history. It began in 1788 with hand tools and, in 1930, moved over into building machine tools. In 1945, the cornerstone of today's success was laid with the launch of the first continuous generating gear grinding machine, incidentally one of Reishauer's many inventions.
