1、加工精度高，反应速度快，稳定性强，减低线性负荷，只要一般 40-100kgf/cm 氮气即可顺畅运作；驱动介质为纯气体氮气，因此不会有油污的产生。
1、High processing accuracy, fast response speed, strong stability, reduced linear load, and smooth operation with general nitrogen of 40-100kgf/cm; The driving medium is pure gas nitrogen, so there will be no oil pollution generated.
2、体积小，节省能源，维护成本低，应用在数控机器、加工中心机上，可轻易达到 48m/min，最高可达 80m/min。
2、Small size, energy-saving, low maintenance cost, suitable for use in CNC machines and machining centers, can easily reach 48m/min, with a maximum of 80m/min.
3、氮气自动平衡配重系统结构扎实体积小而容易安装在主轴单元的重心位置附近，利用其平衡重量，可更有效地减低重力轴向线性伺服马达的负荷，降低电力消耗和发热引起的热变形。
3、The nitrogen automatic balance structure is solid, compact, and easy to install near the center of gravity of the spindle unit. By balancing its weight, it can more effectively reduce the load of the gravity axis linear servo motor, reduce power consumption, and reduce thermal deformation caused by heating.

伺服刹车马达配重
螺杆加大、螺距加大、此法速度较快，但温升快且高，耗电量大，螺杆损耗大，维护成本高。
Servo brake motor counterweight: The screw is enlarged, the pitch is increased, and this method has a fast speed, but the temperature rise is fast and high, the power consumption is high, the screw loss is large, and the maintenance cost is high.
成本高配重块
此法成本低，反应特性差，不能适用于高速切削。需要大空间，高速运动时容易产生主轴单元振动而影响加工精度，刀具容易受磨损，寿命缩短。
Counterweight block: This method has low cost, poor reaction characteristics, and is not suitable for high-speed cutting. Large space is required, and high-speed motion can easily cause spindle unit vibration, which affects machining accuracy. Tools are prone to wear and tear, and their lifespan is shortened.
精度差油压配重
速度中等，反应不够敏捷且精度不高，必须处理油压回路的油温上升，需要高精度的油压阀否则不能持压，即漏油情况比较容易发生。
Hydraulic counterweight (hydraulic cylinder+hydraulic control unit): With moderate speed, less agile response and low accuracy, it is necessary to handle the oil temperature rise in the hydraulic circuit. A high-precision hydraulic valve is required, otherwise it cannot maintain pressure, which means oil leakage is more likely to occur.
易漏油氮气自动平衡配重系统
此法体积小、低耗能、维护成本低，应用在数控机器上，可轻易达到 48 m/min，重复精度高，产品设计变更少、省能源且维护成本低。
Nitrogen automatic balance weight system: This method has a small volume, low energy consumption, and low maintenance cost. When applied to CNC machines, it can easily reach 48 m/min, with high repeatability accuracy, minimal product design changes, energy savings, and low maintenance costs.
