There are four distinct stages in the CNC milling process

CNC milling provides superior precision, accuracy, and production speeds. CNC milling machines are the systems utilized in these operations. The CNC milling process consists of four main steps:

1. CAD Model Creation Engineers design a 2D or 3D part model.

2. CNC Program Conversion The design is exported to a compatible format and converted into machine instructions using CAM software.

3. CNC Machine Setup The machine operator readies the machine and workpiece.

4. Milling Execution The machining program is initiated by the operator.

Precision 3 Axis and 5 Axis CNC Milling Services

Based on your specific needs, budget, and schedule, we will select the optimal milling method. Consult our experienced sales team to identify the perfect solution for your requirements.

3-axis CNC milling is a widely recognized technique for creating mechanical components, utilized across industries such as manufacturing, architecture, design, and art. This straightforward process involves a milling machine that operates on 3 axes (X, Y, and Z), removing material in three primary directions aligned with a flat surface. Ideal for uncomplicated designs without multi-surface requirements, 3-axis CNC milling offers a quick and cost-effective solution for producing simple parts.

5-axis milling incorporates the 4-axis milling axes plus an extra rotational axis, making it the most advanced CNC milling technology available today. It excels at creating intricate and precise parts for industries such as artificial bone production, aerospace, titanium components, oil and gas machinery, automotive molds, medical, architectural, and military. For complex internal designs or models with multiple irregular surfaces, 5-axis CNC milling machines are used to enhance accuracy and reduce both processing time and cost.
