1. High Rigidity
The six major components of this machine tool, such as the base, pedestal, X-axis table, tool holder base, and cross table, are all made of gray cast iron H300, using the resin sand process. The integral casting base is treated with natural aging for over a year, with a density of 6.8-7.3g/cm³, tensile strength σb(MPa): 250, and hardness HB209. They have good strength, wear resistance, and heat resistance, effectively absorbing vibration energy during machine operation, with good damping properties and lubrication performance. The total weight of the casting is 2400Kg.
2. High Precision
The X-axis/Z-axis guide surfaces use linear guides suitable for heavy cutting; the base and cross table use HT300 cast iron, integral casting, semi-finished after machining, and then high-frequency quenching is applied to the guide surfaces. After heat treatment, the guide surfaces are precision ground, and finally, they are manually scraped to ensure that the cross table and X table have at least 20 contact points per square inch. With high-precision linear guide rails, the high-precision machining of the machine tool is guaranteed. All X-axis and Z-axis linear guide rail surfaces are automatically and forcibly lubricated to effectively extend the life of the machine tool.
