High-speed machining centers are not suitable for long-term storage. When there are no processing tasks, the machine tools should also be periodically energized. It is advisable to energize them 2 or 3 times per week and run air for 1 hour each time to reduce the humidity in the machine by using the heat of the machine tool itself. , so that electronic components will not be wet, but also in a timely manner to detect whether there is no battery low alarm to prevent the loss of system settings parameters.
Periodically clean or replace the filters or subfilters of each lubrication, hydraulic, and pneumatic system in the high-speed machining center; periodically check the hydraulic system, add and replace hydraulic oil, and regularly discharge water to the gas pressure system of the pneumatic system. . Machine level and mechanical accuracy are regularly checked and corrected. There are two types of mechanical precision correction methods, soft and hard. The soft method is mainly compensated by system parameters, such as screw backlash compensation, machine tool reference position correction, etc. Hard methods are generally performed during machine overhaul, such as rail repair, ball screw nut pre-tightening adjustment Backlash and so on.
Good power supply guarantee In order to avoid large fluctuations in power supply (greater than ± 5%) and possible transient interference signals, high-speed machining centers generally use dedicated line power supply (such as from the low-voltage distribution room to separate one for CNC machine tools) or add stability. Pressure devices, etc., can reduce the impact of power quality and electrical interference. Formulate effective operating procedures In the use and management of CNC machine tools, a series of practical and effective operating procedures should be established. For example, lubrication, maintenance, rational use, and standardized shift system are the main contents of the use and management of CNC equipment. The establishment and observance of operating procedures is one of the important measures to ensure the safe operation of CNC machine tools. Practice has proved that many failures can be reduced or avoided by obeying operating procedures.
Metal alloy powders are commonly used in thermal spray processes to coat surfaces with a protective or functional layer. These powders are typically made by combining different metal elements in specific compositions to achieve desired properties such as corrosion resistance, wear resistance, or thermal conductivity.
Some commonly used metal alloy powders for thermal spray include:
1. Nickel-based alloys: These alloys are known for their excellent corrosion resistance and high-temperature strength. They are often used in applications where resistance to oxidation and wear is required, such as in gas turbine components.
2. Cobalt-based alloys: Cobalt alloys are known for their high hardness and wear resistance. They are commonly used in applications where resistance to abrasive wear and high temperatures is required, such as in the aerospace and power generation industries.
3. Stainless steel alloys: Stainless steel alloys are used for their corrosion resistance and high-temperature strength. They are often used in applications where protection against corrosion and oxidation is required, such as in chemical processing equipment.
4. Titanium-based alloys: Titanium alloys are lightweight and have excellent corrosion resistance. They are commonly used in applications where a combination of high strength, low density, and corrosion resistance is required, such as in the aerospace industry.
These metal alloy powders can be applied using various thermal spray techniques, such as flame spraying, arc spraying, plasma spraying, or high-velocity oxygen fuel (HVOF) spraying. The specific choice of alloy powder and thermal spray process depends on the desired coating properties and the application requirements.
