The main technical characteristics of VMC-137 vertical CNC machine tool are described as follows: 1. The VMC-137 bed, spindle and other key components are all made of Mihanna (dense baking) castings. The material grade of the casting is FC-30. The casting structure adopts integrated molding technology and box structure. Our company's large pentahedral machining machine is used for processing, which is completed in one clamping process. The machine tool has high rigidity, high strength, and excellent geometric positioning accuracy. And it can ensure the long-term stability and high precision of the machine tool. 2. Unique tool changing mechanism, which uses special materials, undergoes precision machining, and unique heat treatment to make tool changing fast, reliable, accurate (without impact on the spindle), and smooth without noise. The 3-axis loosening tool adopts a unique and stable hydraulic cylinder, which has higher tool changing speed and reliability. It also adopts a floating retraction design to ensure the rigidity and service life of the spindle. 4. The large capacity tool magazine mechanism can store 24 knives and adopts the latest cam type tool changing system. The tool magazine management adopts a random memory type, making tool exchange quick, safe and reliable. (Optional) 5. The spindle adopts precision high-speed bearings. In addition to special grease lubrication inside the bearings, the spindle outer sleeve accessories have a circulating oil cooling system. The spindle can maintain high precision under high-speed and long-term operation. 6. The spindle and three-axis motors use high horsepower alpha series motors, which have large torque output and a wide range. Even at low speeds, there is high torque output, making them suitable for heavy cutting. 7. The X, Y, and Z three-axis sliding rails are all high rigidity hard rails
