1.CNC Machiningof deep cavity molds

In the process of automobile mold manufacturing, if you want to use a three-axis machining center to implement deep-cavity molds, you must lengthen the tool holder and the tool, but when using the five-axis machining center to process deeper and steeper cavities, To create better process conditions for mold processing, the additional rotation and swing of the workpiece or the spindle head can appropriately reduce the length of the tool, thereby preventing collisions between the tool and the tool holder and the cavity wall, reducing the time of processing Tool jitter and damage, tool life is prolonged, and the surface quality and machining efficiency of the mold are greatly improved.

2. CNC Machining of mold sidewall

For the machining of mold sidewalls, the tool length of the three-axis machining center is greater than the depth of the sidewall. The depth of the tool is also determined by the depth of the sidewall. If the length of the tool is increased, its strength will be significantly reduced. 3 times the diameter, so that the knife phenomenon will occur, and the quality of the workpiece will be difficult to guarantee. If a 5-axis machining center is used to process the sidewall of the mold, the swing of the spindle or the workpiece can be used to make the tool and the mold sidewall always appear vertical. When milling the sidewall of the mold, a flat milling cutter can be used, which can improve the workpiece quality and extend tool life.

3. Machining irregular mold surfaces

For the machining of molds with irregular surfaces, it was generally done through a three-axis machining center in the past. The cutting process of the tool cutting mold moves along the entire path of cutting. The cutting process of the cutting edge of the tool will not change. The perfect quality of each part of the mold cannot be guaranteed. For example, molds with frequent changes in curvature and molds with deep grooves can be processed by a five-axis machining center. The cutting tool can always optimize the cutting state, and the tool can optimize the direction of the entire machining path movement. At the same time, the cutter can also perform linear motion, and each part of the mold surface will be perfect.
