Everything you need to know about machining at Dalvoorde Techniek

Machining is a crucial process in metalworking, where excess material is removed from a workpiece to create parts with the desired shape and dimensions. At Dalvoorde Techniek, we have extensive experience with a wide range of machining techniques. Curious about the diverse projects we have completed? Visit our projects page

Turning vs. Milling: What's the Difference?

During turning the workpiece rotates rapidly on a lathe, while a cutting tool removes material. This technique is ideal for creating cylindrical and round shapes, such as shafts, rings, and tubes. By CNC turning the workpiece, we can produce precision parts like motor shafts and fastening rings, ensuring accurate shapes with continuous rotation.

Milling , on the other hand, works differently. The cutting tool rotates rapidly while the workpiece remains stationary. This method is perfect for creating complex shapes and profiles, such as cutting grooves, manufacturing gears, and working on flat surfaces with detailed patterns. Milling is excellent for precise adjustments and prototyping.

Examples:

• Turning: To manufacture a motor shaft that needs to be precisely round and to size, we use turning to achieve the desired diameter and accuracy.
• Milling: For a metal housing with complex cut-outs and patterns, we use milling to create the exact shapes and details.

CNC vs. Conventional Machining?

CNC Computer Numerical Control, machining involves turning metal on a lathe or milling metal on a milling machine using computer-controlled machines. These machines operate with extreme precision, allowing the production of repeatable and complex parts. CNC is ideal for producing large series or custom parts with strict tolerances.

Conventional turning and milling are performed using manually operated machines. This method is suitable for single items or small batches. It includes standard machining techniques such as filing, planing, tapping, broaching, boring, sawing, and drilling. Conventional machining is often more flexible for small series or special adjustments but may be less precise than CNC. We combine both techniques to ensure the best quality for every project, large or small.

Examples:

• Repairing an old machine part with unusual dimensions and shapes, where conventional turning or milling provides the best solution.
• Creating a custom tool or mold for a one-time project, where conventional turning and milling is often more cost-effective and faster than CNC machining.

What is Boring?

Boring and large boring are important machining processes where the workpiece remains stationary, and the tool rotates

These techniques are mainly used for repairing holes in metal products. When a round hole becomes damaged, worn, or deformed, the boring technique can be used to restore it to the correct round shape.

Boring uses a fast-rotating cutting tool to precisely machine the stationary workpiece. Unlike CNC turning, where the tool is directed inward, the boring tool is oriented outward in this process.

Key machining techniques: keyway cutting and broaching

Keyway cutting and broaching are machining processes often used to create specific grooves or profiles in workpieces.

Keyway Cutting:
Keyway cutting is a machining process where a narrow, straight groove is created in a shaft or hub. This groove is designed to accommodate a key, which ensures a secure connection between two parts, such as a shaft and a gear. It prevents the parts from rotating relative to each other. A common example of keyway cutting can be found in machine drive systems, where it is essential to securely connect gears and shafts.

Broaching:
Broaching is a technique used to create internal profiles, such as keyways, but also other shapes like square or hexagonal holes. This process uses a specialized tool called a broach, which is either pulled or pushed through the workpiece. The broach features multiple cutting edges that remove material layer by layer until the desired shape is achieved. A practical example of broaching is creating internal square holes in wrenches or forming keyways in gears.

Which materials are suitable for machining?

Plastic: Versatile and lightweight materials like nylon and PTFE, ideal for components requiring chemical resistance.
Steel: Strong and durable, perfect for creating robust parts that need to withstand heavy use.
Stainless Steel: Corrosion and rust-resistant, making it ideal for parts exposed to harsh environments.
Aluminium: Lightweight and easy to machine, commonly used in applications where weight is a crucial factor.
Brass: Easy to machine with a good surface finish, frequently used for precision parts such as valves and gears.
