What is CNC Milling?
CNC milling is a manufacturing process that uses computer-controlled machines to remove material from a workpiece. The process involves the use of a rotating cutting tool to cut the desired shape from a solid block of material.
The milling machines are highly precise and can produce complex shapes. They can also be programmed to produce multiple identical parts, making the milling process a cost-effective solution for production.
Our CNC Milling Capabilities
Sendot Technology offers custom CNC milling services for plastic and metal parts. With our multi-axis CNC machining centers, we can produce a variety of simple and complex CNC milled parts. Whether you need prototypes or product parts, our experienced teams can provide them with high standards and cost-effectiveness. We also have many surface finish options so that your machined part is exactly what you need it to be.
3-axis, 4-axis, and 5-axis for CNC Milling Services
Sendot Technology has 3-axis, 4-axis, and 5-axis CNC milling capabilities. 3-axis and 4-axis CNC machines operate on the X, Y, and Z axes, which are the most commonly used CNC milling process. They are often applied to produce parts with relatively simple geometry.
5-axis CNC machines are the high standard and advanced type of CNC mill, which represents the manufacturing capabilities of custom CNC milling. With this mill, we can machine 5 sides of a workpiece with one machine without multiple setups. Compared with 3-axis CNC milling, it is significantly more efficient and can be created geometrically complex parts with high accuracy.

CNC Milling Metals and Plastics
There is a wide variety of CNC machining materials available for milling. Typically, the most used are metals and plastics.
Plastic materials are often used in CNC milling because they are easy to machine and have a wide range of properties that make them ideal for many applications. It includes ABS, acrylic, PC, PVC, Nylon, POM, PE, Teflon, etc.
Metal materials are widely used in CNC milling for their durability and strength. Common metals widely used in the milling process include aluminum, stainless steel, and brass. Other materials that can be used for milling are copper, bronze, magnesium, titanium, zinc, etc.
CNC Milling Tolerances & Surface Finish
Tolerances and standard finish can be used in order to help ensure quality and consistency in the milling process. By following these principles, we can avoid many potential issues that could lead to costly mistakes or product defects.
Machining tolerances: When machining a part, the tolerance is the allowable deviation from the desired dimension. The tolerance must be taken into account when setting up the machine and when producing custom milled parts.
At Sendot Technology, we follow the ISO 2768 standards for both machined plastic and metal parts. This ensures that our products meet the highest quality standards. Typically, we can hold a CNC machining tolerance from ±0.005″ (±0.125mm) to ±0.002″ (±0.05mm) or even tight tolerance of ±0.01mm.
Surface finish standards: The surface finish of machined parts are important to consider. This is because it can affect the function of the part, as well as its aesthetics.
We offer the following surface finish standards. The typically machined surface roughness is Ra 3.2-1.6 μm; The smooth machined surface roughness is Ra 1.6-0.8 μm; The super-finished surface roughness is Ra 0.8-0.2 μm.

CNC Milling FAQs
How does CNC milling work?
Unlike additive manufacturing, CNC milling is a type of machining that uses computer numerical control (CNC) technology to remove excess material from a workpiece. It begins with a CAD file. This file is used to create a toolpath, which is a set of instructions that tells the CNC lathes how to move the cutting tools across the workpiece.
What types of cutting tools for milling?
There are many different types of cutting tools that can be used with CNC mills. The most common type is the end mill. End mills are available in a variety of sizes and shapes and can be used for a variety of machining operations. Other common tools include ball nose end mills, chamfer end mills, and dovetail end mills.
What finishing options are used in CNC milling?
The finish on CNC milled parts can provide a protective and decorative surface that is both wear and corrosion-resistant and aesthetically pleasing. There are a number of finishing options available for CNC mills, and the best option will depend on the specific project requirements. Some common surface finishes include Polishing, Anodizing, Powder Coating, Plating like electroless nickel plating, Sandblasting and etc.

CNC milling and turning under one roof
Sendot Technology runs CNC milling and turning in the same shop — 3-, 4- and 5-axis milling plus CNC lathe and mill-turn work, so a part needing both milled features and turned diameters is finished without moving between suppliers, to ±0.05 mm on critical features, with no minimum order and a quote after engineering review.
Milling and turning in one supply chain
- Milling: 3-, 4- and 5-axis machining of housings, brackets, plates, cavities and complex geometry
- Turning: CNC lathe work for shafts, pins, bushings and other round parts — see CNC turning services
- Mill-turn: live tooling adds flats, holes and slots to a turned part in one setup, so no second fixturing error is introduced
- Why it matters: a part that needs both operations at two suppliers picks up a datum shift between them; running both here keeps one reference
- Materials: aluminium, alloy & stainless steel, brass, titanium, engineering plastics — 30+ in total
- Tolerance: ±0.05 mm on critical features · Surface: to Ra 0.2 µm
- Volumes: no MOQ, samples in 3–5 working days
