Due to the needs of epidemic prevention and control, Jiangsu, Shanghai, Guangdong and other places have urgently issued epidemic prevention and control policies for working at home. In order to respond to the needs of the country's epidemic prevention and control, and actively cooperate with the national epidemic prevention and control work, most of the customers' machine tools in the epidemic area have to face emergency shutdown and suspension of production. 

 What should I do in an emergency shutdown? 

 In the face of such an urgent and prolonged shutdown, how should we maintain our machine tools in order to return to normal production and operation more quickly after the end of the epidemic?

 The following needs to be done: First, machine cleaning 

 1.1 Clean the chip and chip liquid on the table, X,Y,Z axis guard. 

 1.2 Clean the cuttings in the tool store, the cuttings on the handle and the cuttings and oil on the claw. 

 1.3 Clean the chip and chip liquid in the cone hole of the spindle, and do not install the tool handle on the spindle. 

 1.4 For long-term shutdown, the chip and screw in the three-axis guard, the chip and oil on the guide shaft should be cleaned up. 

 1.5 To stop the machine, the three and four axes should be moved to the center position. 

 2. Lubrication and rust prevention 

 2.1 Lubricate and grease the transmission parts of the tool store. Grease: ensure the quality of grease. 

 2.2 Grease the mandrel of the spindle cutter loosening mechanism. Grease: Ensure the quality of grease. 

 2.3 Anti-rust treatment of workbench and three-axis cover, dry and apply anti-rust paste. 

 2.4 Apply lubricating grease to the spindle taper hole, and ensure that the grease is of good quality. 

 Precautions before recovery 

 1. Check items 

 (1) Clean the anti-rust oil Clean all parts of the machine with anti-rust oil using a damp cloth and cleaning agent according to the inspection and maintenance instructions before prolonged shutdown. 

 (2) Supply of coolant Fill as required for coolant use. 

 (3) General inspection Cooling system, clamping system, lubrication system, electrical system, etc. 

 (4) Check whether there is oil leakage Check the inside of the machine and hose for oil leakage. 

 (5) Machine preheating After the machine is turned on, the three-axis, main shaft and tool store are run empty for 30 minutes at the speed of 25% to check whether each part is normal. 

 2, the main shaft preheat Before running the machine after the long-term shutdown, the machine must run empty in accordance with the following steps:

 a) Fix the spindle speed at a safe speed of 1000 rpm;

 b) Rotate the spindle at 500 rpm for about half an hour; 

 c) Rotate the spindle at 1000 rpm for about half an hour; 

 d) Stop spindle rotation and preheat each axis (X axis, Y axis, Z axis). 

 3. Special precautions

 (1) After long-term shutdown, the X axis, Y axis and Z axis must run empty for about half an hour before running again;

 (2) If the machine tool is not used for a long time, if the spindle speed is too high, it may cause damage to the spindle bearing or chuck hydraulic cylinder. With the arrival of May, Kunshan finally ushered in victory after a month of hard fighting against the epidemic. Suzhou has been adjusted to a low-risk area, and Kunshan's many districts and towns have been cleared. Many companies and factories are gradually resuming work. But comrades, although Kunshan has been unsealed, it cannot be controlled by paralysis. Dear customers, we should all guard this hard-won victory together.
