Recruiting CNC specialists in the Mettmann district: what really matters

1. Start with your production process

“We are looking for a machinist with CNC experience.”

That identifies the occupational field. But a sound recruitment brief still needs answers to key questions: will this person run an established process, independently set up jobs for different components, or develop new programs from engineering drawings?

The occupation covers a broad range of work. Germany’s Federal Institute for Vocational Education and Training distinguishes between areas including turning, automatic turning and milling systems, as well as one-off and series production. A job title alone therefore does not define the experience a role requires. [1]

For businesses in the Mettmann district, it is worth taking a close look at the specific production task. The Schlüsselregion around Velbert and Heiligenhaus has a strong connection to locks, security technology and architectural hardware. This provides a tangible industrial context, but the individual machines, components and processes still need to be examined. [6]

Our recommendation: before recruiting, ask production management and HR to walk through a typical job together, from the blank and machine setup to inspection of the finished component. Record which steps the new employee will carry out independently and where support is available.

2. Distinguish between operating, setting up and programming

Machining work can include choosing tools, clamping and aligning blanks, starting and monitoring machines, and checking dimensions and surfaces. Germany’s Federal Employment Agency lists these activities as part of the occupational profile. [2]

For recruitment, we recommend separating responsibilities into three areas. A single role may combine them; the table is not a formal classification of occupations.

The key question is: what must this person be able to do without ongoing support after the agreed induction period?

If programs are supplied by production planning, independent CAM programming should only be essential when it is genuinely part of the job. If the new employee must fully prepare changing jobs, experience running machines that others have already set up will not, on its own, demonstrate the required capability.

3. Be specific about turning and milling

“Experience in turning and milling” also leaves too much room for interpretation. State the main focus and the processes actually used.

For a turning role, the brief should clarify questions such as:

• Which machines and controls are used?
• Does the role involve sliding-head or fixed-head turning, bar work or chucking?
• Are live tooling or a sub-spindle relevant?
• What component dimensions and batch sizes are typical?

For a milling role, useful questions include:

• Which machining centres and axis configurations are used?
• Does the work involve three-axis machining, indexed machining or simultaneous five-axis machining?
• How often do components and workholding setups change?
• How much work involves one-off parts, small batches or repeat production runs?

These details help clarify the technical requirements. A job advertisement does not need a complete machine catalogue, but it should make clear which experience is central to the role.

A hypothetical example

A business in Heiligenhaus needs someone to produce recurring milled components in small batches. Production planning provides the programs. The new employee will independently set up the machine, prepare tools and work offsets, prove out the job and check dimensions against the inspection plan.

The relevant profile focuses on setup skills, process understanding and quality assurance. An additional requirement for extensive independent CAM programming would need a practical justification. Otherwise, the business would exclude people whose experience meets the actual needs of the job.

4. Control-system experience: what has the person actually done?

A statement such as “Siemens knowledge” or “Heidenhain experience” needs a follow-up question: which control was used, and for which tasks?

Manufacturers’ training programmes reflect these different skill levels. HEIDENHAIN distinguishes, for example, between operation and setup, conversational programming and more advanced applications. Siemens’ SINUMERIK training covers areas including G-code programming and the graphical ShopMill and ShopTurn interfaces. [3] [4]

The recruitment profile should therefore specify:

• System and version: the control actually installed.
• Depth of use: loading, correcting, extending or creating complete programs.
• Programming method: at the machine or through the CAD/CAM system in use.
• Recent practice: when and how regularly the skills were last used.

A skilled machinist with experience of a different control may be worth considering. Your technical team should assess whether a transition is feasible by reviewing previous responsibilities and planning a specific induction.

“Can be trained” requires someone responsible for the training, time to deliver it and a defined learning objective.

5. Consider materials, tolerances and inspection duties together

“Metalworking” is too general as a description of the materials involved. Name the relevant materials and, where necessary, specific grades or conditions.

Material composition, heat treatment and hardness influence machinability and the choice of tools and cutting data. Sandvik Coromant describes these relationships in its technical materials guide. [5]

For recruitment, this means asking about experience with the materials actually used, such as aluminium, steel, stainless steel, brass or cast iron. Avoid assuming that experience with one material transfers directly to every new task.

Add the quality requirements to the profile:

• Which dimensional and geometrical tolerances matter for typical components?
• Which surface-finish requirements must be met?
• Which measuring instruments and inspection methods will the employee use personally?
• Who inspects and approves the first component?
• Which results must be documented?

Rather than simply asking for “the highest precision”, the technical team should be able to explain the requirements using an approved sample drawing.

6. Discuss shifts and commuting early

A technically suitable candidate must also be able to make the job work in everyday life. Working hours and access to the site therefore belong in the first conversation.

“Must be willing to work shifts” is too vague. Describe the actual arrangement: fixed day shifts, alternating early and late shifts, or a system including nights. Include start and finish times, rotation, possible weekend work and how far ahead schedules are known.

Pay should also be clearly broken down into base pay, weekly working hours, allowances and any other agreed components.

The relevant recruitment area then depends on the actual journey to the factory. For a business in Velbert, neighbouring Wuppertal may be part of that area. Whether the commute is sustainable depends on the exact home and work locations, transport and shift times.

Check together:

• Can the person arrive in time for every scheduled shift?
• Is the journey home after a late shift also practical?
• What daily travel time is sustainable for this person?
• What promised support can the business actually provide?

A fixed radius in kilometres is only an initial guide.

7. Match sourcing and selection to the profile

A precise profile provides the basis for approaching candidates. The next steps should reflect the actual need:

Make job advertisements specific.

Describe the task, machine environment, responsibilities and working conditions clearly. Candidates should be able to assess whether the role fits their experience and everyday life.

Add personal direct outreach.

Active sourcing broadens access beyond incoming applications. An approach should identify a relevant technical connection, such as experience setting up comparable machines or working in a similar production environment.

Expand the search area deliberately.

A regional search can start in the Mettmann district and neighbouring areas such as Wuppertal. Nationwide or international outreach can be added where the profile and the business’s readiness support it. If relocation is involved, consider housing, commuting, workplace communication and induction. Required documentation and administrative conditions should be clarified early for each individual case.

Involve both HR and the technical team in selection.

HR or the recruitment partner structures the initial screening; the technical team assesses technical suitability. Useful questions include:

• “Which job did you last set up yourself, and which steps were your responsibility?”
• “Which program changes do you make independently?”
• “What do you do when a measured feature is outside specification?”
• “Which decisions do you make yourself, and when do you involve others?”

An agreed task based on a non-sensitive sample drawing can complement the interview. Afterwards, record which requirements have been demonstrated, where induction is needed and which questions remain open.

Checklist: is your CNC recruitment profile ready?

Use this checklist with production management and HR. Classify each technical requirement as essential, desirable or trainable.

• Purpose: which specific production need should this appointment address?
• Process: is the focus on turning, milling or a defined combination?
• Machines: are types, axis configurations and relevant features specified?
• Control: are the system, version and required depth of use clear?
• Responsibilities: is it clear who operates, sets up, programs and approves?
• Programming environment: is it clear whether CAD/CAM is required and which system is used?
• Workpieces: are materials, typical dimensions and batch sizes described?
• Quality: are tolerances, measuring instruments, inspection duties and documentation specific?
• Working hours: are shift times, rotation and possible weekend work defined?
• Pay: are base pay, working hours and allowances clear?
• Location: have commuting, transport and, where relevant, willingness to relocate been considered?
• Induction: is someone responsible, and is there a realistic plan?
• Selection: have the technical interview, assessment criteria and decision-making responsibilities been agreed?

A recruitment profile is sound when everyone involved has the same understanding of the job and can explain why each essential requirement is necessary.

Frequently asked questions about recruiting CNC specialists

Do CNC specialists need both turning and milling skills?

That depends on the role. Make both processes essential only if the employee will actually use both regularly. Where production has a clear focus, reflect it in the recruitment profile.

Is experience with the right control brand enough?

That statement alone is not enough for selection. Clarify the control type, tasks and level of independence: were programs simply loaded, modified or created from scratch? Ask the candidate to explain their use of the control through specific jobs.

Can a machinist switch from a different control system?

That may be an option. Assess technical foundations, previous programming tasks and the learning required. The key is whether your business can provide the necessary induction. There is no universal timeframe.

How wide should the search area around Velbert and Heiligenhaus be?

Base it on the commute and shift pattern. Include suitable neighbouring areas such as Wuppertal, but check the actual journey. For candidates from farther away, also establish whether relocation is an option and how their start can be prepared.

What information helps a recruitment partner get started?

Helpful information includes a description of the duties, machines and controls, materials, quality requirements, shifts and pay. Add the key essential criteria and available training support. An approved, non-confidential sample task can make the brief more concrete.
