The QG-PCB30 manual-automatic precision cutting machine uses a speed-regulating motor, which drives the cutting blade through a belt drive to obtain an effective speed. Touch screen display and operation, clear picture, reasonable function layout, and free setting of parameters, making cutting preparation more convenient. The machine can choose the hand-operated wheel on the right to control the spindle propulsion mode or the platform propulsion mode for cutting according to different materials or personal usage habits, or it can automatically cut according to the set parameters. The overall design of the machine body is exquisite, with a built-in independent stainless steel circulating filtered cooling water tank, which is mixed with 80% water and 20% cutting fluid to lubricate the cutting blade and sample, which can effectively avoid heat burns on the sample surface and prevent the guide rails and ball screws from rusting. The machine is equipped with a safety protection function when the cover is opened and shut down. The working area adopts a fully enclosed structure and has a transparent protective cover for observation during cutting. The working platform can be equipped with different clamps, and the clamping device can be freely disassembled and cleaned. The QG-PCB30 desktop cutting machine has a compact body but powerful functions. Used for cutting metallographic samples such as PCB sheets, metal materials within Φ30mm, electronic components, inlays, etc. It has a beautiful and stylish appearance and a convenient human-machine interface. It is cost-effective and is the best choice for cutting small pieces today.
