Our CNC Machining Processes

CNC Milling

3-axis milling for standard parts
High-speed milling for rapid material removal
Micro-milling for intricate, small-scale features

Milling is a process where a rotating cutting tool removes material from the workpiece to create a desired shape or feature. It can be performed on a variety of machine tools, such as:

Vertical Machining Centers (VMCs): The workpiece is mounted on a table that moves in the X, Y, and Z axes, while the cutting tool moves vertically.
Horizontal Machining Centers (HMCs): Similar to VMCs but with the spindle oriented horizontally, which can be beneficial for machining larger workpieces or when heavy cutting forces are involved.

Milling operations include:

Face Milling: Used to create flat surfaces.
Peripheral Milling: The cutting is done by the outer edge of the milling tool.
End Milling: Uses the end of the tool to create slots, pockets, or profiled surfaces.

2-axis turning for cylindrical parts
Multi-axis turning with live tooling for complex parts
Swiss-type lathes for high-precision, small diameter parts

Turning is a subtractive manufacturing process where a workpiece is rotated while a cutting tool moves radially against it to remove material. Common types of turning machines include:

Lathe Machines: Traditional machines used for turning cylindrical parts.
CNC Lathes: Computer-controlled lathes that can perform more complex turning operations with high precision.

Turning operations include:

Straight Turning: Creating straight lengths of material.
Thread Turning: Cutting threads on the external or internal surface of a cylinder.
Taper Turning: Creating a conical shape by adjusting the tool’s position relative to the workpiece.

5-Axis Machining allows for complex shapes to be machined by having the cutting tool and workpiece move in five axes, greatly enhancing the range of possible designs.

Complex Geometries: 5-axis machining allows for the simultaneous movement of the cutting tool along five different axes. This makes it possible to manufacture intricate and highly detailed parts with complex shapes and undercuts in a single setup, significantly reducing production time and improving accuracy.
Improved Surface Finishe: By machining from multiple angles, 5-axis CNC machines reduce the need for multiple setups and repositioning, resulting in smoother surface finishes and fewer tool marks. This process is ideal for industries like aerospace and medical equipment, where precision and aesthetics are critical.
Increased Efficienc: The ability to work on multiple faces of a part in a single setup saves time and labor costs, improving overall efficiency. 5-axis CNC machining also eliminates the need for complex fixtures and multiple machine setups, reducing the risk of human error and increasing production speed.
Higher Accuracy: Thanks to the machine’s ability to access the part from multiple angles without repositioning, 5-axis machining delivers greater dimensional accuracy and consistency. This makes it the perfect choice for industries that require parts with exact specifications and tight tolerances, such as automotive and robotics.
Cost-Effective for Complex Parts: Although 5-axis CNC machines are more advanced, they can be more cost-effective for complex parts due to reduced setup times, fewer tooling requirements, and less waste. This translates to savings in both production time and costs for intricate or detailed components.
