数控开料机主轴使用以及维修保养方法!
来源：http://www.jmycnc.com 时间：2021-10-18
1.轴承选用C级高速角触摸轴承本产品NSK轴承。
1. Class C high-speed angle touch bearing is selected as the bearing. NSK bearing of this product.
2.选用精度钢球坚持器，这样确保了电主轴在高速磨削时的反转精度。
2. The precision steel ball holder is selected to ensure the reverse accuracy of the motorized spindle during high-speed grinding.
3.电主轴外壳冷却选用液循环冷却，降低高速旋转引起的发热温升。
3. The motorized spindle shell is cooled by circulating coolant to reduce the heating temperature rise caused by high-speed rotation.
4.电主轴选用油雾光滑，选用油脂光滑。
4. The motorized spindle shall be smooth with oil mist and grease.
运用方法
Application method
1.开机前有必要接上油水管，做到电主轴先接通油水管后再发动主轴电机，安装时水管油管不能接错。主轴左右两头为水管，中间为油管(数控钻铣床主轴是油脂光滑，不选用以上方法。)
1. Before startup, it is necessary to connect the oil water pipe, so that the motorized spindle can be connected with the oil water pipe first, and then start the spindle motor. During installation, the water pipe and oil pipe can not be connected incorrectly. The left and right ends of the spindle are water pipes and the middle is oil pipes (the spindle of NC drilling and milling machine is smooth with grease, so the above method is not selected.)
2.运用电主轴时应先接油雾管点，管点接头应清洁净，防止污物进入形成轴承烧坏。操作时应看电主轴前端部稍有油雾泄出后，才干发动电主轴，油雾光滑主张选用5号主轴油调理，进油管为20-30滴/分，常常查看不能断油，不然会形成主轴损坏。
2. When using the motorized spindle, the oil mist pipe point shall be connected first, and the pipe point joint shall be clean to prevent dirt from entering and burning the bearing. During operation, the motorized spindle can be started only after the oil mist at the front end of the motorized spindle leaks out slightly. The oil mist is smooth. It is recommended to use No. 5 spindle oil for conditioning. The oil inlet pipe is 20-30 drops / min. it is often checked that the oil cannot be cut off, otherwise the spindle will be damaged.
3.操作时，有必要做到主轴彻底停止转动后，才封闭油雾，这样才干延长运用寿命，说明发动不宜过火频频。
3. During operation, it is necessary to close the oil mist after the main shaft completely stops rotating, so as to prolong the service life, indicating that the engine should not be started too frequently.
4.电主轴运用前有必要查看砂轮接杆是否同轴，如不同轴超过0.03毫米应还砂轮接杆，不然既损坏电主轴，又磨欠好作业，磨削时应留意不要碰击，应校正后再进去磨削。
4. Before using the motorized spindle, it is necessary to check whether the grinding wheel connecting rod is coaxial. If it is not coaxial more than 0.03mm, return the grinding wheel connecting rod, otherwise the motorized spindle will be damaged and the grinding operation will not be good. During grinding, pay attention not to bump, and go in for grinding after correction.
维修保养
Maintenance
1.电主轴所接中频电源额外电压，频率应与电主轴技术参数相符，电主轴转速能够改动频率来调正，一起电压也成正比改动。
1. The frequency of the additional voltage of the medium frequency power supply connected to the motorized spindle shall be consistent with the technical parameters of the motorized spindle. The speed of the motorized spindle can be adjusted by changing the frequency, and the voltage is also changed in direct proportion.
2.运用过程中应防止电主轴轴端部与工件发生意外碰击。
2. During operation, the end of the motorized spindle shaft shall be prevented from accidental collision with the workpiece.
3.运用过的电主轴暂不必，使用压缩空气吹清水管内冷却液，避免生锈，阻塞小孔。并在外表涂上防锈油、轴端加保护装置放于干燥处保存。
3. The used motorized spindle is not necessary temporarily. Use compressed air to blow the coolant in the clean water pipe to avoid rust and blocking the small hole. The surface shall be coated with anti rust oil, and the shaft end shall be protected and stored in a dry place.
4.应尽量削减空工作，开机前应查看进出冷却水石非疏通。
4. Empty work shall be reduced as far as possible, and the inlet and outlet cooling water shall be checked before startup.
