Introduction: Compared with ordinary machine tools, CNC machine tools are automatic machines that process parts automatically according to the program.
What is a CNC lathe?
CNC lathe is a high-precision, high-efficiency automatic machine tool that can process complex workpieces such as linear cylinders, sloping cylinders, and arcs. It also has functions such as linear interpolation and arc interpolation, and it can be used in mass production of complex parts. A good economic effect.
Compared with ordinary machine tools, CNC machine tools are automatic machines that process parts automatically according to the program. After the programmer has programmed the program, the program is input into the numerical control device to direct the machine tool. The purpose of machining different parts can be achieved by simply changing the program that controls the movement of the machine.
However, the normal use of CNC lathes must meet the following conditions:
one. Place the environment
CNC lathes need to be placed in a dry, dark place and away from sources of vibration. Otherwise it will affect the stability and reliability of the machine.
two. voltage
The power supply voltage required by CNC lathes must be strictly controlled. The voltage fluctuation must be within the specified range and ensure its stability. Otherwise, the CNC system will not work properly.
three. temperature
The ambient temperature needs to be less than 30 degrees and the relative temperature is less than 80%. Excessive temperatures will reduce the life of the control system components and lead to increased failures.
In addition, it is also important to note that: The parameters set by the manufacturer in the CNC lathe control system must not be arbitrarily changed. The parameters set by the manufacturer are directly related to the dynamic characteristics of the machine components. In addition, lathe attachments must not be replaced at will. The free replacement of attachments will result in mismatching of various parameters, and may even cause unexpected accidents.
Finally, there is a point to note: Please ensure that the pressure of the hydraulic chuck, hydraulic knife holder, hydraulic tailstock, hydraulic cylinder are within the allowable stress range.
Nickel-based alloy powders are commonly used in plasma transfer arc welding (PTAW) due to their excellent corrosion resistance, high temperature strength, and good weldability. These alloys are typically composed of nickel as the base metal, with various alloying elements added to enhance specific properties.
Some commonly used nickel-based alloy powders for PTAW include:
1. Inconel 625: This alloy powder is widely used for PTAW due to its high strength, excellent resistance to corrosion, and oxidation at elevated temperatures. It is commonly used in applications involving seawater, chemical processing, and aerospace industries.
2. Hastelloy X: This alloy powder is known for its high-temperature strength and oxidation resistance. It is commonly used in applications involving gas turbine engines, industrial furnace components, and chemical processing.
3. Monel 400: This alloy powder is known for its excellent resistance to corrosion, particularly in marine environments. It is commonly used in applications involving seawater, chemical processing, and oil refining.
4. Inconel 718: This alloy powder is known for its high strength, excellent resistance to corrosion, and good weldability. It is commonly used in applications involving aerospace, oil and gas, and nuclear industries.
5. Inconel 601: This alloy powder is known for its excellent resistance to high-temperature oxidation and corrosion. It is commonly used in applications involving heat treatment equipment, chemical processing, and power generation.
These nickel-based alloy powders can be used in PTAW processes to create high-quality welds with excellent mechanical properties and resistance to corrosion and high temperatures.
