The CY-DWC300-A precision reciprocating type diamond wire saw uses diamond impregnated wire (0.3mm dia.) for cutting all kinds of materials (especially for larger size crystals, such as Si, Ge, and GaAs, etc. with boule diameter up to 12" (300 mm) and leaves a smooth cutting surface. Y and Z axis and the rotary sample stage are all driven by the stepper motors which provide the precise, stable and varied cutting of the samples. The cutting program can be set in the touch screen controller which includes the feeding speed, cutting depth, width, slice number, etc.
