Machining safety-critical rail parts: Compliance and risks

The rail sector is one of the key industries we manufacture precision engineered parts for at M-CNC. There are many reasons why CNC machining is essential to the rail industry and helps to ensure rail safety.

Why precision engineering matters in the rail industry

Rail systems must meet the highest levels of safety in their operations. The accuracy and traceability of precision engineered parts supports rail safety specifications.

Rail vehicles travel at incredibly fast speeds, carry immensely heavy loads, and run almost continuously. The durability and reliability of every piece of rail equipment must be guarantee, as mechanical failures can cause:

  • Expensive breakdowns
  • Service delays
  • Passenger and staff safety risks
  • Loss of revenue and service reputation

How precision engineering ensures rail component safety

The safety of precision engineered rail components is rooted in the stringent quality control practices CNC engineers like M-CNC adhere to.

1. Material traceability

Every component we manufacture for our rail components comes with full material traceability. This attests to the superior quality and excellence of the raw materials we use to machine parts.

We also provide full documentation on the materials used in our parts, including First Article Inspection (FAI) reports.

2. Compliance

As a RISQS verified and AS9100 Rev D certified supplier, rail customers can be assured that, as a rail sector supplier, M-CNC:

  • Meet rail safety regulations and risk assessments
  • Ensure supply chain resilience
  • Deliver parts reliably and fulfil contractual obligations

Rail companies can also view important information about M-CNC and be assured we have the required accreditation to meet their needs.

3. Meeting tight tolerances

Rail components often must be manufactured to meet tight tolerances. This is usually the case when the part is safety-critical. At M-CNC, we meet these tight tolerances in several ways:

  • CAD/CAM software: Used at every stage of development, our CAD/CAM software integrates with our CNC machines and ensures every part is manufactured to an unparallelled degree of precision.
  • CMM measurement: Our industry-leadings CMMs measure the physical geometry of complex rail components, testing that they meet the intent of the original design and flagging any quality issues so they can be fixed.

In-process quality checks and full compliance enable us to manufacture rail-safety critical parts.
