CNC milling is a precise manufacturing process that uses rotating cutting tools to remove material from a workpiece. Controlled by a computer, this method allows for the production of complex shapes and high-precision components. It is commonly used to create milling machine parts, ensuring accurate dimensions and surface treatments for a variety of industries and applications.

What are milled parts?

Besides installing a compatible Internet browser (such as（Google Chrome or Microsoft Edge）), there is no additional software needed. There is no need for any setup by the customer, even when we upgrade the service.

Which materials can be processed with CNC milling?

Various materials can be processed using CNC milling, including metals such as aluminium, steel, stainless steel and titanium as well as plastics, wood and composite materials. The choice of material depends on the specific requirements of the end product. meviy currently offers the materials steel, stainless steel, aluminium and plastic for CNC milling.

What are the advantages of CNC milled parts?

CNC milled parts offer high precision, repeat accuracy, and the ability to manufacture complex shapes with tight tolerances. One key advantage of milled parts is their versatility in producing both small and large production runs efficiently. Additionally, the CNC process allows for consistent quality across all units, making it ideal for industries requiring high reliability and complex geometries. The automation of the process also reduces human error and increases overall productivity.

In which industries are CNC milled parts used?

CNC milled parts are used across a wide range of industries, including automotive, aerospace, medical technology, electronics, and mechanical engineering. These parts are essential for producing high-precision components such as engine parts, surgical instruments, and electronic housings. Due to their versatility, milled parts are also critical in sectors like robotics and energy, where exact specifications and reliability are required for both small and large-scale production.

How precise is CNC milling?

CNC milling offers exceptional precision, often reaching micrometer-level accuracy. This makes it ideal for applications requiring tight tolerances, such as in aerospace or medical technology. The process ensures consistent results, allowing for the creation of intricate, high-quality parts with minimal deviation. CNC milling's precision is a key factor in industries where reliability and exact specifications are critical, ensuring the functionality and safety of complex components.

What does it cost to manufacture CNC milled parts?

The cost of manufacturing milled parts depends on several factors, including material choice, design complexity, tolerances, and order quantity. While milled parts produced through CNC milling can be more expensive than traditional methods, the process offers higher precision and efficiency. These advantages often lead to long-term savings, especially in custom or small-batch production, due to reduced waste and faster turnaround times for complex designs.

Available Sizes

The sizes suitable for automatic quotes can vary depending on the material, as different materials have different processing requirements.

Supported Shapes

The following illustrations show which edits are available with meviy and which are not.

For the machining of milling parts, meviy offers the option of 3-axis machining. With meviy, parts can be machined from 6 sides as listed below. This means that parts that require a diagonal hole to the surface cannot be machined. For pocket shapes, pockets can be produced with chamfers, but radii are required in all corners of closed pockets so that the end mill can manufacture them. Open pockets can be produced without radii, while bores can be machined vertically and horizontally, including multiple bores or slotted holes with counterbores. Vertical and horizontal machining is also possible for slotted holes. Chamfers up to a size of C15 can be produced with meviy.

Hole Types for CNC-Milling Parts

In the machining service, various form elements are carefully identified and classified as holes to meet the specific requirements of each project. Holes can be customized, either as straight or precision holes, depending on the requirements and functionality of the hole.

Under certain criteria, it is possible to change the diameter of a hole and convert it into threaded holes, through holes or countersunk holes to suit the wide range of applications.

Both single-stage and two-stage bores allow for flexible design options where the design of the bore can be adjusted and toleranced at each step to ensure maximum precision and efficiency.

Example of two different milled parts manufactured with meviy.

Hole Types that can be quoted with meviy
