Drilling is another casting machining type that only creates holes. It is commonly used in many applications, especially in manufacturing and construction. Casting drilling is widely used in foundries to make molds and finish the cast parts.
The drilling machine has a rotating cutting tool called a drill bit. The object remains stationary. The cutting tool gradually removes the material and creates a hole. The machine presses the drill but against the material. As it rotates, it cuts away the material to form a hole.
Features & Benefits
- Drilling is suitable for all solid materials.
- It is a cost-effective method.
- This method offers high accuracy (up to ±0.01 mm).
- There is a wide range of drill bit options.
Limitations
- Drilling can create heat, which can deform thinner materials.
- The hole depth depends on the size of the drill bits.
