  • Parts with Complex Structures Such As Curve Contours or Curved Surfaces: The plane curve contour of the part, that is, the part has a complex curve with internal and external contours, and the processing surface is parallel or perpendicular to the horizontal plane. In three-dimensional space coordinates, the surface of a part is usually a point variation on the surface. It is usually designed by mathematical models. During the machining process, the milling cutter is always in point contact with the machined surface. The surface of the part is usually processed by three-coordinate CNC milling because it needs to be programmed with the help of the CNC system.
  • Compared with conventional machining, CNC milling has the characteristics of high machining accuracy, complex shape parts and a wide machining range.

VIDEOS RELATED TO MILLING PARTS

What is CNC Milling?

CNC machining is one of the most common manufacturing processes. This is mainly due to its high accuracy, precision and tight tolerance ranges.

In fact, with CNC machining, it is possible to accurately manufacture parts of the same size in small batches, while achieving tolerances as small as tenths of a millimeter.

There are many types of CNC machining, the common ones are CNC milling and CNC turning.

CNC milling is a machining process that uses a rotating tool to remove excess parts of a block of material until the desired custom shape is formed.

In addition, CNC milling can machine very complex parts while meeting the tight tolerance requirements of the milling part.

CNC milling has been continuously modified and refined to produce precision parts that meet the exacting demands of today’s demanding industries.

CNC milling is mainly used in subtractive manufacturing. Fix the parts to be milled in the fixture on the CNC worktable, and then process the raw materials through the X, Y, and Z axes of the CNC milling machine, and rotate the tool spindle at a very high speed to cut the material, so as to achieve the ideal parts.

Features of CNC Milling

The application of CNC milling has the characteristics of flexibility and variety. It is used in the processing of various parts with different structures and complex shapes.

On the CNC milling machine, drilling, boring, plane milling, end face milling, tapping and other processes can be completed. In addition, CNC milling has high precision and high repeatability, which can meet the requirements of high-quality machining.

CNC milling effectively avoids operator errors and effectively maintains the consistency of part dimensions during small batch processing.

The CNC milling machine has the functions of a drilling machine and a boring machine at the same time.

On the multi-variety and small-batch production line, CNC milling is used to centralize the processing procedures, which not only improves production efficiency but also reduces the error rate of parts clamping.

In addition, CNC milling also has the function of fast forward, backward and fast positioning of the tool holder, thereby reducing maneuvering time.

CNC milling can also process complex profiles that are difficult to machine by CNC lathes, and even the plane curve contours and spatial surface contours of parts. This is because CNC milling has the characteristics of multiple feed coordinates and feed axis linkage.

Industrial Applications of CNC Milling
  • Medical – CNC milling is used to manufacture parts used in the hygiene and medical sectors, such as orthopedic implants and surgical instruments.
  • Electronics – Electronic hardware, housings, metal laths, panels, engravings, dust collectors and other electronic parts are made with milling machines.
  • Military – Three- and five-axis machines are used to produce CNC milled parts for aircraft, vehicles, and weapons.
  • Aerospace – Aircraft components require high-performance CNC milling services to manufacture aircraft engines, transmissions, hydraulic manifolds, landing gear, electrical connectors, housings and more.
  • Automotive – Automotive custom milling components, including engines, battery boxes and interiors.
  • Food – CNC milling technology is designed for components in food processing machinery, blenders, grinders, shredders, cleaning equipment, and more.
  • Machines – Milling parts required by the machine tool industry, such as fasteners, fittings, shafts, hydraulics and machine components, are designed using CNC milling technology.
What is the Difference Between Three-Axis, Four-Axis and Five-Axis Machining of CNC Milling

3-axis – This is one of the most widely used techniques for OEM CNC machining parts. A standard CNC milling machine has three axes, and the cutting tool moves along the X, Y, and Z axes to mill the part.
3-axis CNC machining can be used for various tasks such as drilling, rapid prototyping, contouring and slotting. This kind of milling machine is relatively simple, and generally refers to three axes that move linearly in different directions, such as up and down, front and rear, and left and right. Three axes can only machine one surface at a time, and the most effective CNC machining surface is only the top surface of the workpiece.

Four Axis – We use this high performance milling mill to make more complex parts. It incorporates an additional motion profile through rotation on the vertical axis, allowing for greater flexibility and introducing more continuous machining.
Four-axis processing involves the same process as three-axis CNC machining, however, the milling is performed on an additional axis. A four-axis CNC machine with end mills operates on the X, Y, and Z axes, and also includes rotation around the X axis, which is called the A axis.

5 Axis – These machines are the most advanced and widely used type of CNC routers. A five-axis additive manufacturing combines three conventional axes with two additional degrees of motion. It operates by increasing the rotation of the table and spindle.
With this computer-aided design, we can machine 5 sides of the workpiece with one machine without having to do multiple setups.
5-axis CNC machines are the best on the market right now. Its g code can create precise and complex parts for aerospace products, CNC milling turning parts, automotive mechanical components, medical products, precision CNC milling parts, mold making, and more. This machine is ideal for your project as it offers the option of single-step machining, reducing production time. It also makes complex geometries easier to access and increases tool life.
