Blow molding machine tools and workpieces can adhere to low temperatures, which in many cases extends tool life. On the other hand, in the high-speed cutting operation, the cutting amount is shallow, and the cutting edge of the cutting edge is extremely short. That is to say, the feed is faster than the heat.
Low cutting forces result in small and common tool twists. This, combined with the stable machining allowance required for each tool and process, is one of the prerequisites for efficient and safe machining.
Because the typical depth of cut in high speed cutting is shallow, the radial forces on the tool and spindle are low. This reduces wear on the spindle bearings, rails and ball screws. Blow molding machines are also an excellent combination of high-speed cutting and axial milling. They have a small impact on the spindle bearings. This method can be used to oscillate with a tool with a long overhang.
High-yield cutting of small-scale parts, such as roughing, semi-finishing, and finishing, is extremely economical when the total data removal rate is relatively low.
High-speed cutting of blow molding machines achieves high yields in normal finishing and excellent surface quality. The surface quality is often lower than Ra 0.2 um.
The use of high-speed cutting makes it possible to cut thin-walled parts. With high-speed cutting, the knife is short, and the impact and tortuosity are reduced.
The precision of the mold has improved, and the assembly is simple and faster. No matter who or how the technology is, you can get the appearance and precision of CAM/CNC. If the time spent on cutting is slightly more, the time-consuming manual polishing operation can be significantly reduced. Can often be cut by 60-100%
Some machining, such as quenching, electrolytic machining and electric discharge machining (EDM), can be greatly reduced. This will reduce capital costs and simplify logistics. The blow molding machine replaces electric discharge machining (EDM) with cutting, and the life and quality of the mold are also improved.
The use of high-speed cutting can be quickly changed by CAD/CAM, especially when new electrodes are not required.
One of the first principles of high-speed cutting is to reduce production costs through high yields. Blow molding machines are primarily used in finishing operations and are often used to process hardened tool steels. Another policy is to improve the overall competitiveness after shortening the production time and delivery time.
