Plunge Milling Plunge milling has been around for a long time and can be the most consistent form of high metal removal, especially on older machines incapable of operating at high feedrates. This consistency is a result of efficient toolpaths, as there is little wasted tool motion when compared to more common methods of machining [...]
There are 10 inherent benefits that a good shrink fit chuck can offer a mold shop:1. Unsurpassed accuracyA properly produced shrink fit chuck should be able to guarantee 0.00012″ (3 microns) maximum run-out at three times the cutting tool diameter. This accuracy is very repeatable from operator to operator. […]
First-rate Mold Solution Co. Ltd is based in China and engaged in supply of industrial design, mold design, molding analysis and project management service. […]
Specializing in milling and EDM’ing large, complex 3-D geometry for various tool steels for both molds and foundry patterns, Lawrenceburg, first-rate mold company was looking to reduce its cycle times, according to President Steven. The addition of Metal Slash Mill allowed him to reduce a 10-hour cycle time to two hours. […]
When looking for toolholder solutions for any type of machining, it is always good to first focus on three main features that a toolholder must bring you: […]
Word of first-rate mold company’s abilities traveled quickly, leading to an order for an automotive grille piece that put their injection molding knowledge to the test. […]
Selecting the proper electrode material to produce a fine surface finish is vital to the success of the application. It is important to understand which material provides the potential for achieving an acceptable finish without the need for excessive handwork or polishing. By realizing the role that the microstructure of the material plays in producing [...]
A common belief in the moldmaking industry is that a lower quality electrode material can be used to produce superior surface finishes if a high quality EDM machine is used. While the technologies of the newer generation EDM sinkers have allowed the EDMer to become more proficient in the application, […]
With graphite, the magic words are high speed. High speed machining centers with 30,000- to 60,000-rpm spindles are capable of accelerated feeds that serve to reduce cycle times and improve surface finish, as well as edge quality. […]
Automation for EDM drills comes in two main forms: (1) simple mechanical toolchangers and (2) comprehensive robotic systems. Both perform essentially the same function. However, where a toolchanger usually just moves the tool chuck in and out of the machining head (albeit automatically), a robot can also transport electrodes, guides and workpieces in and out [...]
