Common examples of drill bits for precision CNC machining include:
Spotting Drills: They help create shallow or pilot holes.
Drill Presses: These are important for custom drilling tasks.
Screw Machine Drills: They produce holes without an initial pilot hole.
Chucking Reamers: They help enlarge previously created holes.
Peck Drills: They reduce the number of chips made from workpieces.
Electrical Discharge Machining (EDM) involves using controlled electrical sparks to shape materials into desired shapes. Many customized CNC parts supplier machinists also refer to it as spark eroding, spark machining, die sinking, or wire burning. During this process, the technician places the component under an electrode wire.
The programmed machine emits electrical discharges from this wire, producing intense heat. The heat melts the material and is flushed with an electrolytic fluid to give the desired feature or shape.
Moreover, EDM creates precise slots, micro holes, angled or tapered features, and several other complex features on workpieces. It is the ideal process for hard metals that are usually difficult to machine.
These tools help cut materials using a high-powered, computer-controlled plasma torch. These plasma torches can reach temperatures over 50,000 degrees Fahrenheit. As a result, they can quickly melt workpieces and create cuts in the material. Materials used with plasma cutting machines must be electrically conductive. Examples of such materials include steel, aluminum, stainless steel, copper, and brass.
