As the demand for better cutting tools increases, cutting tool suppliers also continuously develop products that can pass manufacturers’ demands. Through the years, a lot of materials for the manufacture of cutting tools have been experimented upon; some have passed the standards while others were simply dropped. Today, there are only two types of cutting …
Five-axis machining is here to stay and most modern injection mold making shops use it on a daily basis. Finding the right work holding device is critical to success in 5 axis machining. Five axis machining offers many benefits for injection mold making and is rapidly becoming the norm in CNC milling. One of the problems …
Despite the fact that a great deal of precision surface grinding has been replaced by Wire EDM, there is still a demand for the skillful use of grinding wheel dressers. This is one of those toolmaking skills that requires considerable time and patience to master. The skill to accurately dress angles and radii on surface grinding wheels is half art and …

By far the majority of copper electrodes are manufactured on CNC machines these days (thankfully!), but the need for grinding copper electrodes still comes up frequently. The main difficulty with grinding copper electrodes is the loading of the wheel and the burrs thrown up. There are several simple solutions to this problem. With the proper technique you …
Do not skimp on the design Some shops do not have an in-house designer and must outsource their design work. This is fine and works quite well- unless the boss decides to save money by cutting costs on the design. This is just asking for trouble. Even with high-quality mold design, building an injection mould …
