At R D Castings we undertake many second operation-machining processes, as it is not always suitable to use CNC controlled equipment for every machining process.

These second operation processes include manual drilling, tapping, hydraulic press work, linishing, hand deburr work and shot blasting to name but a few.

Whilst these processes may increase the labour content of certain jobs, it can sometimes still be a cheaper option than fully automating a process. This is due to potentially high set up costs involved in automation, which on low volume work would not be a viably option.

With this in mind R D Castings has invested money in making these processes as efficient as possible in the use of the latest technology in light guarded presses and fully automated shot blasting facilities.

This then allows for the most cost effective solution to all of our customers needs, for both low and high volume work. If you have any special requirements for second operation machining, please feel free to talk to us as there is always a cost effective solution to a problem.

Below is a list of some of the second operation machining that is carried out at R D Castings:

  • Single head tapping – with torque control and digital depth control.
  • Multi head tapping – with up to 8 heads tapping simultaneously.
  • Drilling – convention single spindle drilling machines.
  • Multi stage drilling – 4 station Medding continuous drilling.
