Different metals require different machining processes.
Due to the high precision we achieve, precision zinc die casting generally requires very little machining. The machining characteristics of zinc and zinc alloys are first-rate, and a range of machining processes are generally available.
Drilling – We can achieve better and more economical drilling results in a range of operating conditions. Contact us directly to find out how
Tapping — Zinc die-cast alloys are easy to tap and form high-quality threads and holes. Threads can be cut or formed with or without lube and are easily tapped with extrusion taps to produce rolled threads. Extrusion tapping is faster than cutting taps, and lubrication is essential.
Reaming – Our precision zinc die casting process is so precise that the cores are cored to the size required for reaming. This means we avoid drilling operations that require the manufacture of expensive dies
The close-packed hexagonal lattice structure of magnesium die-cast alloys makes them ideal for machining processes.
Magnesium alloys can be machined with good results using dies that are specially designed to machine aluminium. However, due to the low cutting resistance and relatively low heat capacity of magnesium, the molds we use have smooth cut surfaces, sharp cutting edges, large relief angles, small rake angles, few blades (milling cutters) and can ensure good chipping during CNC milling die casting parts. Flow geometry.
No cutting fluid is used in conventional machining methods of magnesium alloys. However, we have found that the use of cutting fluid reduces the risk of fire, eliminates material build-up on the mold, removes chips easily, and most importantly extends the life of the mold
The most widely used die casting alloy, Aluminium Alloy 380, is ideal for machining applications.
High-speed steel tools are usually used for machining aluminum.
When machining aluminum, helical flute reamers are preferred over straight flute reamers.
High clamping forces are not required when machining aluminum. By using a moderate clamping force, we avoid dimensional changes due to deformation.
