As we know, most precision parts are standard parts. They are normal and used widely. But some of the precision parts are specially shaped. These custom-made precision parts are used in some cold stamping tools and forming dies or in some automated systems.
Precision parts have various kinds of types, as we talked before, punches and dies, cores and cavities, ejector pins and sleeves, guide pins and bushings, mold inserts and mold bases, etc. Most of them have the standard sizes, you can buy the standard parts on the Misumi platform. But Most of them also have custom-made precision parts according to some industries’ custom products or newly developed products for special requirements. For example, the automotive industry, the medical industry, the electronics and semiconductor industry, especially the rectangular connector and terminal block industry. These are precision mold/tool/die components.
There are also some special precision parts used in the automated machine systems. A part of them are mechanical parts and fixture parts. They need to be machined in special shapes and to meet high-precision requirements. As they need to be assembled into the automation system. These automated systems may be automatic assembly machines or SMT/SMD machines for some microelectronics parts or PCB chips.
Among these precision parts, custom-made cutting punches are one of the most common items. As custom-made precision parts are mostly hardware metal parts, not plastic parts. They need to be made in the cold stamping tools, metal forming mold, metal blanking die, or press die, etc.
These thin sheet metal parts need to be punched (or called stamped) piece by piece in the cold stamping process.
The hardness of the cutting punches is important. The hard metal is usually used, like cemented tungsten carbide or high-speed steel. Their hardness requires HRA 80~90 (carbide) or at least HRC 62~65 (high-speed steel). So, the carbide cutting punches are mostly required. There are standard parts and also custom-made precision parts.
The hard metal is comparatively difficult to cut and process. The custom-made hard metal parts are more difficult to process and machine. As these special carbide parts also need high precision. We need to use high-end machining equipment, like Profile Grinder and High Precision EDM. And also, we need experienced and skilled technical workers to operate the machining equipment. Then, the high hardness high precision custom tungsten carbide punches can be made.
Except for the punches, there are also some other special parts, for example, carbide wear parts, aluminum alloy parts, fixture parts etc.
All in all, custom-made precision parts need a spirit of artists to do it. Together with advanced equipment and sophisticated technicians, we can make them well.
