EXAKT has perfected a surface grinder that maintains plane-parallel grinding with a user-determined shutoff capability. Sample thicknesses in the range of 20 µm can be achieved easily. Accurate to within ± 1.5 microns, the system uses abrasive papers and films to prepare the required surface.
Grinding machine-related factors can affect the workpiece surface finish. These include: Wheel/hub assembly balance: If the grinding wheel assembly is not balanced to an acceptable level, it can result in chatter and/or poor surface finish. Balancing can be carried out using equipment such as a static balancer, dynamic/manual balancer, …
A comprehensive review of micro-grinding: emphasis on toolings, performance analysis, modeling techniques, and future research directions
This paper discusses the performance of the minimum quantity lubrication (MQL) in micro-grinding based on ground surface roughness and tool life. The effects of grinding and lubricating parameters on machining performance are studied. Experiments for dry grinding and grinding with pure air are also conducted for comparison. It is …
The recent paper proposes a hybrid micro-grinding process for ultra-precision meso/micro components of monocrystalline silicon manufacturing. The proposed technique utilizes the chemical modification solution to modify and soften the surface layer and then manufactures meso/micro-structures via micro-grinding. A special chemical …
The CryoMill is a cryogenic grinder designed with user safety in mind. The liquid nitrogen flows through the closed system and the user never comes into direct contact with LN 2 which ensures a high degree of operational safety. The automatic cooling system guarantees that the grinding process is not started before the sample is thoroughly cooled.
The grinding and polishing processes are achieved with an accuracy of less than 5 μm depending on the selected type and fineness of the sandpaper. Follow the EXAKT sample preparation system to determine …
