How is a CNC龙门mill processed?

The龙门 machining center usually finishes milling operations using the down milling method. However, it is preferable to use the up milling method for better processing results. When the gantry milling machine is up milling, the milling width should be approximately equal to 2/3 of the milling cutter diameter, ensuring that the blade can immediately cut into the workpiece without resistance. If it is less than 1/2 of the cutter diameter, the blade will start to rub against the workpiece, as the cutting thickness decreases during the cut, and the feed per tooth will also decrease due to the narrowing of the radial cutting width. The rubbing results in a shorter tool life. For carbide tools, increasing the feed per tooth and reducing the cutting depth is more beneficial. Therefore, during rough milling, if the radial cutting width is less than the cutter radius, increasing the cutting speed will improve the tool life, thereby shortening the processing time of the gantry milling machine. Of course, fine milling requires a smooth workpiece surface, so the cutting speed should be limited.

What is the difference between龙门mill and lathe?

1. The lathe is a machine tool primarily used for turning operations on rotating workpieces using cutting tools. It also allows for various other加工 methods such as drilling, reaming, tapping, thread cutting, and rolling. The lathe is primarily used for processing shafts, disks, sleeves, and other components with rotating surfaces.

2. Machining centers and drilling machines, among other rotating processing equipment, are derived from lathe technology. A milling machine is a machine tool that uses milling cutters to machine workpieces. Typically, the rotation of the milling cutter is the main motion, while the movement of the workpiece and cutter is the feed motion. In addition to being capable of machining flat surfaces, grooves, gears, threads, and splines, milling machines can also process more complex contours. They have higher power than planers and are widely used in mechanical manufacturing and repair departments. Moreover, they can also be used for turning surfaces, boring holes, and cutting operations.

Overall, the龙门millers boast sufficient rigidity, high power, ease of operation, simple structure, and comprehensive functionality, making them widely applicable in the field of mechanical manufacturing.
