When the cold winter came, I could only see how cold the thick coats, gloves, and hats of the armed people were when they were wrapped. Therefore, those mechanical equipment will also change due to changes in temperature, so it is particularly important to do winter maintenance. Now briefly introduce somemethods of winter maintenance of CNC Machined Instrumentation, I hope to help everyone.

First,how to maintain the CNC machine chip remover in winter to extend the life ofthe chip remover?

There are many types of chip conveyors and chip removers for CNC machines. Various types of CNC Machined Instrumentations have different characteristics due to their different functions, structures and systems. Its maintenance content and rules also have their own characteristics. According to the type of machine chip remover and its actual use, and referring to the machine tool chip remover manual, the necessary routine and hierarchical maintenance system should be formulated and established.

Strict adherence to operating procedures and routine maintenance systems Operators of CNC equipment must strictly abide by operating procedures and routine maintenance systems. The technical quality of the operator is an important factor affecting the failure frequency of the chip removal machine. When themachine chip breaker fails, the operator should pay attention to maintainingthe scene, and truthfully explain the situation before and after the failure to the maintenance personnel, in order to facilitate analysis and diagnosis of thecause of the failure. And eliminate it in time.

Second,selection method of machine tool guide rail oil, metal cutting fluid, hydraulic oil and grease Metal cutting machine tools are large and varied, and their structural characteristics, machining accuracy, degree of automation, working conditions and working environment conditions are very different, and the requirements for the lubrication system and the lubricant used are also different. Machine tools are usually installed in indoor environments. The maximum ambient temperature in summer is 40 °C. When the temperature in winter is below 0 °C, heating isusually used to make the ambient temperature higher than 5-10 °C.High-precision machine tools require a constant temperature air conditioning environment, generally around 20 °C. However, due to the high precision and automation of many machine tools, the requirements for lubricant viscosity(oxidation resistance) and oil cleanliness are more stringent. Different specifications and sizes of different types of machine tools, even on the same machine, due to different workpiece conditions, lubrication requirements aredifferent. For example, the spindle bearings of high-speed internal grinding machines and the heavy loads of heavy machine tools, the lubrication methods and lubricant requirements for low-speed spindle bearings are very different.The former needs to be lubricated with an oil mist or oil / gas lubrication system and uses a lower viscosity lubricant, while the latter needs to be lubricated with an oil bath or a pressure cycle lubrication system and lubricated with a higher viscosity oil.

Third,there are many types of CNC Machined Instrumentations. Due to their different functions, structures and systems, each has different characteristics. Its maintenance content and rules also have their own characteristics.Specifically, according to the type of machine tool and its actual use, and in accordance with the requirements of the machine tool manual, formulate and establish the necessary routine and hierarchical maintenance system. Here are some common daily maintenance points.

1.Strictly observe operating procedures and routine maintenance systems.

2.Prevent dust from entering the CNC equipment.

3.Regularly adjust the tightness of the main shaft drive belt to prevent the belt from slipping; check the constant temperature oil tank of the main shaft lubrication, adjust the temperature range, replenish the amount of oil in time,and clean the filter; extend the tool clamping device in the main shaft, and agap will appear after use This will affect the clamping of the tool. The displacement of the hydraulic cylinder piston must be adjusted in time.

4.Regularly check and adjust the axial clearance of the screw pair to ensure the accuracy and axial rigidity of reverse transmission; regularly check whether the connection between the screw and the bed is loose; replace the screw protection device in time to prevent dust or debris from entering.

5.Regularly clean or replace each lubricating, hydraulic, filter or sub-filter ofthe pneumatic system; regularly perform oil quality inspection and hydraulic system inspection, add and replace hydraulic oil; and regularly drain the water filter of the pneumatic system.

6.Regularly check and correct the machine level and mechanical accuracy.

7. CNC equipment is a highly automated advanced processing equipment. Advanced processing equipment has a complex structure. Inorder to give full play to the efficiency of numerical control equipment, it must be properly operated and carefully maintained to ensure the normal operation and high utilization of the equipment.
