The design of the new ESTUN E-300 numerical control control system was developed in close cooperation with eston engineering department. Clarity and coherence are Eston's new design language. The large area of dark green reflects the consistent tone of the brand's products. The classic silver handle is very eye-catching, engineering and easy to operate. The product has simple shape and smooth lines. Three aluminum plates are used as decoration and matched with keys with full design sense, so that the product is beautiful without losing the sense of equipment, and the production cost is also well controlled. The 7-degree angle tilt design of the product conforms to the man-machine helps workers to have the correct standing posture when working. The regional key arrangement visually distinguishes the working area to reduce misoperation. The differentiated key design conforms to the user's usage habits. For workers who work in the front line with CNC panels, the most important thing is safety. ESTUN's unique internal system effectively reduces the dangerous situations that workers can encounter, followed by efficiency. The key arrangement of man-machine is the fundamental way to improve production efficiency and reduce misoperation.
