龙门外防护采用四开门设计（龙门加工中心三开门设计），两侧为推拉门，前后为贯通式对开门，极大方面客户上下工件。

龙门横梁有楼梯式检修平台，极大方便对Z、Y轴的检测维修与保养。

龙门X轴采用支撑式滑轮组内防护。有效的支撑了防护的重量，使防护在运动时，始终保持与导轨的平行，不易产生变形防水可靠性得到提高，寿命得到了提高。Y轴采用了全封闭耐腐蚀的风琴式防护，具有防护效果好封闭效果好等特点。

The external safety enclosure of the gantry adopts a four-door design (compared to the three-door design of gantry machining centers); the two sides feature sliding doors, while the front and rear are through double-opening doors, greatly facilitating the loading and unloading of workpieces for customers. 

The gantry beam is equipped with a stair-like maintenance platform, greatly convenient for inspecting, repairing, and maintaining the Z and Y axes. 

The X-axis of the gantry uses a support-type pulley group with internal protection. This effectively supports the weight of the protective guard, ensuring it remains parallel to the guide rail during movement, reducing deformation and enhancing waterproof and reliability, thus increasing the lifespan. The Y-axis features a fully enclosed, corrosion-resistant bellows-type protective cover, which offers excellent protection and sealing performance.
