In this series of blogs, we’re talking in more detail about the individual services we provide to our customers, with this particular blog covering CNC milling. So, let’s get started.
CNC Milling: What is it?
CNC Milling is a specific type of machining offered by many CNC machining manufacturers such as PT Engineers. The process uses computerised controls to produce a custom-designed component made to an accurate finish. Many different industries use CNC milling services due to the level of precision and consistency that it can provide.
How does CNC milling work?
CNC milling services start with a CAD (computer aided drawing). This CAD file can be read by the milling machine so that it can understand the paths the machine’s tools need to take in order to turn the designs into physical components. The milling machine removes parts of the material based on the design specifications in the CAD. It uses rotary tools to cut away at the initial material used and the function of these cutters are controlled by the machine’s computer. Minimal human input is required to complete the CNC milling process.
CNC Milling Machine Features
The exact features of a CNC milling machine can vary depending on what capabilities the machine can offer. However, at its most basic level, most milling machines will have:
- Column – this is the main support structure for a CNC milling machine.
- Knee – the knee is an adjustable part that is fixed to the column. It supports the saddle and the worktable and can be lowered or lifted on the Z-axis.
- Saddle – the saddle is housed over the knee of the machine but under the worktable. Saddles can be moved parallel to the axis of the spindle if needed.
- Worktable – the worktable is the area that is on top of the saddle. The workpiece is fastened onto the worktable and is usually quite adjustable depending on the type of machine.
- Spindle – this rotating component is operated by an electric motor and holds either the machine tool or the arbour (if on a horizontal milling machine).
- Machine tool – the machine tool is the part which performs that actual milling operation. Held by the spindle, the machine tool removes the material from the workpiece to create the desired shape.
CNC Milling Machine Advantages
There are many advantages to using a CNC milling machine, we’ve listed the top benefits below.
Less Labour Intensive
CNC milling machines require very little manual labour. The level of production these machines can deliver is incredibly high and no manual production can achieve the same output. Consequently, the simpler the design is, the less human intervention needed.
High Production Output
CNC milling machines operate at high production levels due to being highly automated. With this in mind, it’s the go-to manufacturing process if businesses are looking for parts to be produced in a high volume.
Uniformity
As with all CNC machining tools, CNC milling machines can achieve the highest levels of accuracy. In addition, each movement is directed by a computer programme. Therefore, means that every part produced will carry the same precise design.
