Leica EM KMR3 Leica Glass Knife Making Machine produces high-precision glass knives. By using the balanced fracture method, the mechanical components of the instrument accurately balance the counterweight, and high-precision stainless steel hemisphere supports the lower part of the glass strip, making the weight and pressure borne by both sides of the glass strip scratch accurately equal, and making the contact surface between the glass strip and its lower support smaller, ensuring that the glass strip is completely balanced and fractured, producing high-quality blades. The instrument adopts ergonomic design, making it easy to use and more comfortable.
