KDVM 855L CNC vertical machining center

KDVM 855L CNC vertical machining center was built in 2021 in China by Zhejiang KAIDA Machine Tool CO., LTD. The machine, distinguished by its high efficiency and reliability, is an excellent choice for precision machining of workpieces with a maximum weight of 800 kg. The machining process is performed inside a large work space by means of a high-speed spindle and cutting tools taken from a 24-position magazine. A specially designed high-pressure system continuously cools the tools during machining, guaranteeing a significant extension of their overall service life. Process stability, on the other hand, is ensured by an extremely rigid bed made of the highest quality cast iron, which eliminates any vibration and oscillation during even the most intense challenges.

The KDVM855L CNC machining center is offered with extensive equipment from renowned brands. It features, among others, an advanced SIEMENS CNC control, a 3D measuring probe and a chip conveyor. The total weight of the machine is 5450 kg.
