What is CNC machining technology? a one-stop, complete guide – MXY Machining

Modern manufacturing uses a lot of CNC machining technology to create complex parts that are highly accurate and productive. Below are some of the most common types of CNC machining processes, their applications, and their benefits.

what are types of CNC machining technology processes?

1. CNC Milling

CNC milling is a process where material is removed from a workpiece by rotating multi-point cutting tools. It can produce many different shapes, such as gears, flat surfaces, slots, and intricate three-dimensional structures. CNC machining technology can operate along multiple axes (3, 4, or 5) to enhance precision and capability.

Applications include:

• Automotive parts
• Aerospace components
• Medical devices

2. CNC Turning

In CNC turning, a single-point cutting tool moves linearly to remove material and form cylindrical shapes while the workpiece is rotated by a lathe. This process is ideal for producing parts like shafts, bushings, and other rotational components.

Industries utilizing CNC turning include:

• Automotive
• Aerospace
• Machinery manufacturing

3. CNC Drilling

CNC drilling creates exact cylindrical holes in the workpiece by rotating drill bits. This process is essential for creating holes for screws, bolts, and other fasteners. CNC drilling machines can perform various operations, including:

• Spot drilling
• Peck drilling
• Reaming

4. CNC Grinding

CNC grinding uses abrasive wheels to remove small amounts of material and achieve a high-quality surface finish. There are different types of grinding, such as:

• Surface grinding
• Cylindrical grinding
• Centerless grinding

Applications include:

• Finishing components like bearings
• Shafts
• Tools

5. CNC Electrical Discharge Machining (EDM)

EDM is a non-traditional machining process that uses electrical discharges (sparks) to erode material from the workpiece. There are two main types:

Applications include:

• Mold making
• Tool and die manufacturing
• Aerospace components

6. CNC Laser Cutting

CNC laser cutting machines use a high-powered laser beam to cut materials with exceptional precision. This method is ideal for cutting:

• Metals
• Plastics
• Composites

Industries benefiting from CNC machining technology include:

• Automotive
• Aerospace
• Medical

7. CNC Waterjet Cutting

CNC waterjet cutting uses a high-pressure stream of water mixed with abrasives to cut through materials. This process is suitable for materials sensitive to high temperatures, such as:

• Metals
• Stone
• Glass
• Composites

Common applications are found in:

• Aerospace
• Automotive
• Architectural

8. CNC Plasma Cutting

CNC plasma cutting uses a plasma torch to cut metals that conduct electricity, such as aluminum and steel. This process is known for its speed and efficiency in cutting thick materials. It is widely used in:

• Metal fabrication
• Automotive repair
• Industrial construction

9. CNC Boring

The process of boring involves precisely enlarging an already-existing hole to a specified size and concentricity. CNC machining technology machines are used to create accurate and smooth holes in:

• Engine parts
• Hydraulic systems
• Other critical components

10. CNC Broaching

Broaching uses a toothed tool (broach) to remove material and create specific shapes, such as:

• Keyways
• Splines
• Complex contours

This process is useful for high-precision applications in:

• Automotive manufacturing
• Machinery manufacturing

11. CNC Honing

Honing improves the geometric form and surface texture of a workpiece by using abrasive stones that move back and forth over the surface. This finishing process is commonly used for cylindrical surfaces, such as:

• Engine cylinders
• Bearings

12. CNC Lapping

Lapping involves rubbing two surfaces together with an abrasive to achieve extremely flat surfaces and high levels of accuracy. This CNC machining technology process is essential for applications requiring precise surface finishes, such as:
