Materials Machined

M&M Turned Parts Ltd work in range of bar turning grade materials. These fall into three main categories:

  • Non-Ferrous (Brass, Aluminium, Stainless Steel)
  • Ferrous (Mild Steel, Alloy Steel)
  • Engineering Plastics (Nylon, Acetal)

These above categories represent the core of our business therefore we can offer components ranging from 2mm up to 65mm diameter. Component lengths of up to 500mm can be achieved on our Sliding Head CNC Machining Centres.


We have many years of experience in machining most grades of brass including the following:

  • CW614N
  • CW602N
  • CW712R
  • CW606N
  • CW721R

Brass is generally a free-machining material which is therefore well suited to our automatic machinery allowing 24 hour production.

Stainless Steel

Over the years we have machined a vast range of stainless steels:

  • 303 (1.4305)
  • 304 (1.4301)
  • 316 (1.4401)
  • 416 (1.4005)

Due to our range of cnc machinery we are therefore able to offer both simple and complex stainless steel components. We have developed special in house processes for machining the harder grades of this material category.


Currently 75% of our materials machined are in different grades of steel. Our Fixed Head CNC Machines are well suited to machining steel because of their rigidity and power. Here are some of the popular grades that we manufacture turned parts from:

  • 230M07/230M07PB
  • 605M36T
  • 708M40T
  • 817M40T

Although mainly 230M07PB Mild Steel, we also do have regular work from a lot of the harder grades as mentioned above. The grades therefore shown above are just some of the materials machined at M&M Turned Parts Ltd.
