• Most bearing damage is caused by impurities (debris, dirt, water, etc.); these can also interfere with the lubrication of the grease.
• Sealing air or air supplied externally to apply pressure must be absolutely clean. Water and oil must be separated from the air.
• The air supply must be filtered for impurities. A dehumidifier is a must!
• If the copper-lubricated spindle has been stored for a long period of time, it should be preceded by 1-2 hours of low-speed operation. If the copper-lubricated spindle is stored for a long period of time, it should be run for 2-3 hours every 3 months in accordance with the commissioning instructions to prevent deformation of the copper.
• The bearing cage may make noise, but this is not a sign of bearing damage and will go away after a period of time when the spindle is running.
• Spindles that have not been in service for more than two years require disassembly and analysis to exchange for new copper. If so, please contact HQ.

For oil-lubricated spindles, please comply with the following

• Most bearing damage is caused by impurities (debris, dirt, water, etc.); these also interfere with oil lubrication.
• The spindle must be well oiled before running.
• Be sure to check the oil supply (you can do this by removing the oil supply hose from the spindle and dropping it on a white cloth).

• For oil lubrication: Check and clean each oil supply pipe.
• For oil lubrication: Cut the end of each oil pipe at 90°.
• For oil lubrication: Check the air supply.
• Check the required air pressure on the spindle side and adjust if necessary.
• Check the quality of the coolant (Check if additives are needed)
• Check the coolant flow rate.
• Check that the spindle is rotating in the correct direction.
• Check the air pressure in the sealing air.
• Check the concentricity of all tools.
• Turn on the main switch to make sure the sealing air is working.
• Run the spindle at 10% of full speed for about 15 minutes, then gradually increase the speed for about an hour, and let it run for a while. If the temperature of the spindle exceeds 55°C, stop running the spindle and let it cool down. Repeat this procedure until the copper is dispersed. Check the spindle for vibration. If there is vibration, the toolholder needs to be balanced along with the tool.
• Make sure that the tool is balanced to a reference of G2.5 at rated speed. Please refer to DIN ISO 1940-1/2.

• The spindle should only be operated according to the above tips if it has been idle for more than 4 months.
• If it has been idle for less than that, do not run the spindle for the normal run time (8-15 seconds) when it is cold to prevent warping due to temperature changes.
• We recommend warming up the spindle at half speed for about 15 minutes. Once the spindle reaches operating temperature, you can accelerate and decelerate normally (8-15 seconds).

• The working environment of the spindle must be constantly checked to avoid damage to the spindle itself. This ensures a long service life of the spindle. If any of the abnormalities described in these precautions occur, the spindle must be stopped to prevent further damage.
• Examples of abnormal situations: Noticeable changes in the spindle, strong vibrations or problems during operation, unusual noises, defective peripherals.

• The storage area for the spindle must be dry (maximum humidity 55%) and well-ventilated.
• Outdoor storage of the spindle is not allowed.
• If the temperature during storage or transportation is lower than 5°C, make sure that all coolant is removed. This can cause serious damage to the spindle.
• The allowable storage temperature for the spindle is -10°C to 55°C.

• 스핀들의 보관장소는 건조(최대 습도 55%)와 통풍이 잘되어야 합니다.
• 스핀들의 옥외 보관은 허용되지 않습니다.
• 보관 또는 이동 중의 온도가 5°C보다 낮을 경우 모든 냉각제가 제거되었는지 확인하십시오. 스핀들에 심각한 손상을 일으킬 수 있습니다.
• 스핀들의 허용보관 온도는 -10°C~55°C입니다.

• The spindle benefits from regular maintenance, and it is recommended that you clean the area between the spindle and the toolholder (Taper face). The tapered face should be cleaned at least once a week. Cleaning should only be done with the sealing air switched on.

• The allowable operating temperature range is a minimum of 18°C and a maximum of 40°C.
