When it comes to the
system, its basic requirement is that the machine tool is required to adapt to dry cutting. The dosage of supplied air and liquid as well as the relevant data of the tool must be stored in the data control unit. Due to the need for automated production tool changes to ensure lubricant supply in the shortest possible time, changes in lubricant injection and pressure should be avoided. It is critical to quickly open the control pulse switch and close the supply conduit.
Generally speaking, external
system provision can be considered to be entirely metered. Restricted supply generally depends on ease of access to the processing area. For internal systems, spindle transmission is generally used. Since there are many interfaces in the supply system, the adaptability of the supply system is particularly important. A major difficulty is the centrifugal effect on the oil mist as the spindle rotates. The spray may separate and become lodged in the spindle. Unbalanced cross-sections and high-speed rotation of the spindle may affect solvent mixing.
It is very important that the system provides accurate and effective lubrication to the cutting tools. The system needs to provide better dispersion of liquid. A single channel is generally used to supply aerosols over long distances, and the mist liquid is separated and delivered. A two-channel system allows adjustment of bead size and response in the shortest possible time. A system typically has many different supply tools requiring varying amounts of lubricant and air. Based on this fact, a further requirement for the system of numerically controlled machine tools is to complete the integration.
