Custom Online CNC Milling Services

At RapidDirect, we have a variety of CNC milling machines to meet diverse manufacturing needs. Our inventory includes 3-axis, 4-axis, and 5-axis CNC milling machines.

The 3-axis machines are perfect for simple operations, handling basic cutting tasks along the X, Y, and Z axes.

Our 4-axis machines add an extra rotational axis, allowing for more complex geometries and more efficient production of parts with features that require continuous machining around a fourth axis.

Finally, our advanced 5-axis CNC milling machines offer the highest level of precision and versatility, enabling the creation of intricate parts with complex shapes and angles.

These machines are capable of machining in five different axes simultaneously, reducing the need for multiple setups and ensuring exceptional accuracy and quality in every component we produce.

RapidDirect offers comprehensive CNC milling capabilities tailored to various industry needs. We can machine parts with maximum dimensions of 4000 x 1500 x 600 mm and minimum dimensions of 5 x 5 x 5 mm, accommodating a wide range of project sizes. Our milling machines can work with various materials, including metals, plastics, and composites. We achieve tight tolerances, typically ±0.01 mm for 5-axis milling, ensuring precision and consistency. Our lead times are competitive, ranging from 3-7 days for simpler 3-axis tasks to 7-14 days for more complex 5-axis projects. We also provide additional services such as surface finishing, heat treatment, and quality inspection to ensure that every part meets the highest standards of quality and performance.

CNC milling and CNC turning are both subtractive manufacturing processes, but they differ in how the material is removed.

In CNC milling, the workpiece is stationary, and the cutting tool moves across multiple axes to remove material and create the desired shape. This process is ideal for complex parts with various features such as slots, holes, and contours.

On the other hand, CNC turning involves rotating the workpiece while a stationary cutting tool removes material. This method is best suited for producing cylindrical parts, such as shafts, rings, and bolts. While milling can handle more complex geometries, turning is typically faster and more efficient for producing round parts.

CNC milling and CNC routing both involve cutting materials using computer-controlled machines, but they serve different purposes.

CNC milling machines are designed for precision work with metals, requiring high rigidity and the ability to handle significant cutting forces. They are used for producing intricate and complex parts with tight tolerances.

CNC routers, however, are typically used for softer materials like wood, plastics, and composites. They operate at higher speeds and are ideal for cutting larger sheets into parts with less emphasis on precision. Routers often feature a gantry-style design, allowing for quick and efficient handling of large workpieces, while milling machines focus on detailed, accurate machining.

When a 3D model or drawing does not specify a particular fillet size, standard practice is to add fillets with a radius that balances strength and machinability.

Typically, fillets with a radius of 1/3 to 1/5 of the cavity depth are added. For general purposes, a fillet radius of around 1 mm to 3 mm is commonly used. This size helps to reduce stress concentrations and improve the overall durability of the part.

However, the exact size can vary based on the material being used and the specific requirements of the part. Larger fillets are often preferred for softer materials, while smaller fillets may be used for harder materials to ensure structural integrity without compromising precision.
