Metal Machining

Why choose Radshape for Metal Machining services?

The machine shop in our facility was completely refitted as recently as 2016, creating a purpose built facility that made use of the very latest in state of the art CNC turning and milling technology. It is just one part of the service we offer to all of our clients.

Our HAAS vertical machining centres, 3 and 5 axis and lathes are capable of producing anything from simple machined parts through to complex and intricate components.

2019 saw a new 5 axis machine added to the plant list.

If you have a design that needs machining, or an idea that you want to turn into a machine design, then get in touch with Radshape today.

Clients working in a specialist field such as the automotive and marine sectors need parts to be machined to the strictest possible specifications for reasons of value, safety and – in the case of luxury motor vehicles – aesthetic appeal.

What is meant by Metal Machining?

Metal machining is a broad term encompassing various processes involved in the cutting, shaping, or forming of metal parts through the use of machines. Machining can be used to create a seemingly infinite number of parts for a variety of applications across many sectors. These sectors include automotive, aerospace, electronics, consumer and commercial products, medical, and defense, among many more.

Metal machining today is usually controlled by CNC programming; CNC stands for Computer Numerical Control and ensures the machining process is predetermined to improve accuracy and repeatability across the products.

There are several different methods of metal machining, each with its own advantages and disadvantages.

What is the Machining Process?

The machining process can be done by several methods, which may be combined in order to get your desired result. The most common categorisations of machining are turning, milling and drilling, though there are additional miscellaneous operations such as shaping.

Turning

Turning is a subtractive form of machining as it cuts away at the workpiece. Turning involves using a stationary cutting tool to remove material from a rotating workpiece. This process is typically used to create cylindrical or conical shapes.

Milling

Milling, like turning, milling is subtractive – cutting away at the workpiece with tooling. Milling uses a rotating cutting tool to remove material from a workpiece that is stationary; this is the main difference between the two when considering turning vs milling processes. Milling can be used to form a variety of shapes.

Drilling

This is the third way of categorising how metal can be shaped; drilling is the process of using a cutting tool to create holes in a workpiece, essential for any later manufacturing or assembly work.

Whilst these three categories largely encompass the machining process, machining can also be carried out by less conventional methods. Chemical machining (using chemicals to cut away at the workpiece); water jet cutting (cutting with the use of high-pressure water); ultrasonic machining (a type of abrasive machining which uses vibrations of a tool and fine particles to shear away the workpiece); and thermal machining (using heat, such as processes like EDM) are becoming increasingly popular methods of machining.

What are the types of machinging tools?

To complete the machining process, a plethora of tools are needed.
Machining tools can be designed and manufactured as needed for operations, so are typically broken down into a single-point cutting tool or a multi-point cutting tool.

As the name suggests, single-point cutting tools have one cutting edge, whilst multi-point cutting tools may have several. On multi-point cutting tools, more than one edge is able to connect with the workpiece at one time; for this reason, they are good for high volume operations. A grinder is an example of a multi-point cutting tool.

On the other hand, single-point cutting tools are generally used on a lathe, due to the nature of the stationary tool. A single-point cutting tool is easier to design and manufacture but has a lower rate of productivity and a higher rate of wear due to only one cutting edge being used. An example of a single cutting tool is a boring tool.
