How to Maintain CNC Machining Machine

CNC machine tools are mainly focused on strengthening the daily maintenance. The key maintenance work has the following contents: daily inspection, weekly inspection, monthly inspection, quarterly inspection and half-year inspection. CNC processing CNC machine tool preventive sexual care detailed as follows:

1. Daily Inspection of CNC Machining Machine Tools

Its key items include hydraulic system, spindle smooth system, guide smooth system, cooling system and air pressure system. Daily inspection is based on the normal conditions of each system to be tested. For example, when the process test of spindle smooth system is carried out, the power supply lamp should be on, the oil pressure pump should operate normally, and if the power supply lamp is not on, the spindle stop form should be maintained, which is related to the mechanical engineer. Maintenance.

2. Weekly Inspection of CNC Machining Machine Tools

Its key items include machine tool parts and spindle smooth system, which should be inspected accurately every week. It is unique to eliminate iron chips and clean up external debris for machine tool parts.

3. Monthly Inspection of CNC Machining Machine Tools

The main thing is to check the power supply and air in the dryer. The power supply voltage is rated at 180V-220V under normal conditions, and the frequency is 50Hz. If there is an exception, it should be measured and adjusted. The air dryer should be dismantled once a month and then washed and equipped.

4. Quarterly Inspection of CNC Machining Machine Tools

Quarterly inspection should focus on machine tool bed, hydraulic system and spindle smooth system. For example, when inspecting the machine tool bed, we should focus on the accuracy of the machine tool and whether the machine tool level meets the requirements of the manual. If there are any problems, it should be related to the mechanical engineer as soon as possible. When inspecting the hydraulic system and the smooth spindle system, if there are any problems, the new oil 6oL and 20L should be replaced and washed.

5. CNC Machining CNC Machine Tool Half-year Inspection

Half a year later, the hydraulic system, spindle smooth system and X-axis of the machine tool should be inspected. In case of defects, new oil should be replaced and then washed. After comprehensively understanding and managing the knowledge of patient prevention and sexual protection, we must have a deeper understanding and necessary management of the causes and treatment of the extraordinary phenomena in the oil pressure system. For example, when the phenomenon of oil pump not injecting oil, abnormal pressure, noise and other phenomena occur, we should know what the key reasons are and what the corresponding treatment methods are.

The causes and treatment of the extraordinary phenomena in the oil pressure system should be understood from three aspects:

(1) There may be low liquid level in the tank, reversal of the oil pump, insufficient rotation speed, high oil viscosity, low oil temperature, congestion of the filter, excessive volume of the suction pipe, air suction at the intake port, damage to the shaft and rotor, etc. For the key reasons, there are corresponding treatment methods, such as filling oil, confirming the label, etc. When the oil pump reverses, change it, etc.

(2) Abnormal pressure means excessive or insufficient pressure. The key reasons are also various, such as inappropriate pressure setting, bad coil behavior of pressure regulating valve, abnormal pressure gauge, leakage of oil pressure system, etc. Relevant treatment methods include: disassembly and washing according to the constitutional pressure configuration, replacement of a normal pressure gauge, sequential inspection according to each system, etc.

(3) Noise is mainly caused by oil pumps and valves. When the valve has noise, its reason is that the flow exceeds the rated criterion, and the flow should be adjusted appropriately. When the oil pump has noise, the reason and the corresponding treatment methods are also many-sided, such as high oil viscosity, low oil temperature, the treatment method is to raise the oil temperature; when there are bubbles in the oil, the air in the system should be released, and so on.
