The mobile gantry structure, the beam and the bed are processed as a whole, and the equipment has high precision, good rigid and stable operation.Machine base: frame structure welded with high quality pipe, professional welding, secondary aging treatment, precision machining of large gantry milling machine. These design and processing methods ensure the machine has excellent shock resistance, high rigidity and stability.The guide rail is equipped with a dust cover to prevent dust and debris from falling into the guide rail to affect the movement, keeping clean and smooth movement. The stainless steel plate is installed at the connection between the dust cover and the beam to prevent the spark cover from being quickly damaged and burning
