Used KOMATSU NTC MWM 444A #9289846 for sale

KOMATSU NTC MWM 444A is a sophisticated crystal growing, sawing, and slicing system that is designed to facilitate crystal production. It enables efficient fabrication of high-quality crystals with precise saw thickness control, a low-temperature crystal growth environment, and an array of high-grade slicing processes. MWM 444A features a crystal growth chamber that is designed to maintain an optimal environment for crystal growth, with a temperature range of -15 ˚C to 65 ˚C. It also has a quartz ampoule for high purity crystals, alongside a metal ampoule for single crystals. An additional feature is the optical microscope, which allows for precise positioning of the sample with a spatial resolution of 0.05 µm. Once the crystal has been grown, the next step of the process is to saw off the crystal into a thin slice. This is accomplished through the use of a diamond saw that can cut crystal slices with a precision of 0.02 mm. The saw blade is also water-cooled for enhanced safety, and has a feature that is designed to reduce the dust contamination of the sample during the sawing process. After sawing, the thin crystal slices can be sliced into even thinner wafers using a polishing and slicing machine. This machine is equipped with a diamond blade for slicing, as well as a polishing wheel and a chemo-mechanical polishing head for enhanced sample quality. The wafers of a desired size can then be prepared for device fabrication. In summary, KOMATSU NTC MWM 444A is an advanced crystal growing, sawing, and slicing system designed to facilitate the production of high-quality crystals. It features a low-temperature crystal growth chamber alongside a diamond saw for precise sawing of the crystal. It also features a polishing and slicing machine for high-precision slicing, as well as optical microscope for precise positioning of the sample.
