Businesses will need to decide whether to have their CNC machining capabilities in-house or outsource it to a specialist partner. For many smaller companies, outsourcing can be a great choice to unlock the highest levels of precision manufacturing without significant expenditure on top-level machines, software, training and staff.
But, this isn’t just a cost-effective exercise, there are many benefits in outsourcing CNC machining services, let’s explore them below.
The Business Case for Outsourcing CNC Machining
Outsourcing CNC machining can make commercial sense for reasons that extend beyond reducing manufacturing costs. Businesses can gain access to specialist equipment and expertise while maintaining greater flexibility as production requirements change. It can also reduce the need to dedicate internal resources to manufacturing processes.
However, outsourcing is not automatically the right choice for every business. The most suitable approach depends on factors such as production requirements, order volumes, project frequency and pre-existing capabilities.
Reducing the Cost of In-House Machinery and Infrastructure
Bringing CNC machining in-house requires considerably more than purchasing machinery. Businesses may also need to invest in tooling, software, suitable workspace, servicing and equipment upgrades. There are ongoing costs associated with maintaining machinery and ensuring it remains capable of meeting changing production requirements.
For smaller businesses, these initial investments can represent a substantial and even unmanageable commitment, particularly when equipment is not set to be used continuously. Outsourcing can instead turn a significant capital investment into a more predictable and accessible production cost.
Accessing CNC Expertise Without Expanding Your Workforce
Operating CNC machinery and preparing components for production requires specialist knowledge, from interpreting technical drawings to programming, setting up equipment and achieving specified tolerances.
Outsourcing provides an alternative by giving businesses access to established machining expertise without necessarily expanding their own workforce. This can be particularly useful when specialist manufacturing skills are required for individual projects, new product tests, one-off runs or occasional production requirements.
Making Production More Flexible
Manufacturing demand rarely remains constant. A business may need CNC machining for prototypes or one-off components before moving into short production runs and, eventually, larger repeat orders. An external CNC partner can provide additional capacity as requirements change, without requiring the business to permanently increase its own machinery, workspace or workforce.
Improving Consistency Across Repeat Components
In any production industry, consistency is key. Whether it is in making sure components fit, look right, last the required amount of time or anything else, consistency is crucial. Using an outsourced CNC machining solution allows you to employ a dedicated workforce for your project, increasing reliability in quality and uniformity in dimensions, tolerances and repeatability.
Expanding What Your Business Can Manufacture
Outsourcing can give businesses access to machining capabilities that they do not have internally. Depending on the requirements, this may include CNC cutting, routing, turning or another more complex machining operation. Having access to these capabilities can broaden the range of components and projects a business is able to undertake. For SME’s, this can open up their order book for more advanced work without the costly investments of tooling, training and staffing.
Freeing Internal Teams To Focus On Higher-Value Work
CNC manufacturing has the potential to take over a considerable amount of capability planning with programming, setup, production, inspection, quality checks, finishing and equipment maintenance. However, by outsourcing your CNC capabilities you will open up your internal team for other less demanding tasks. For instance, if you workshop produces components through CNC machining and you assemble them afterwards, you could simplify workloads by outsourcing the machining, allowing your staff to take more care in assembly and finishing.
When Does Outsourcing CNC Machining Make The Most Sense?
Outsourcing CNC machining can be a sensible option when businesses need to increase their manufacturing capacity, either without investing and committing to additional equipment or if it is a temporary project. It may benefit companies without in-house CNC machinery, as well as those whose existing machines are fully occupied.
What Should Businesses Look For In A CNC Machining Partner?
Selecting a CNC machining partner involves more than just looking at the quoted price. Businesses should check that the supplier has suitable machinery, experience and material capabilities for the required work. It is also highly important to establish whether they can support both prototypes and ongoing production moving forward.
Then there is accurate communication regarding drawings, specifications and tolerances is essential, alongside dependable lead times and project management. Prior to selecting an outsourced CNC provider, it also pays to review previous work and relevant experience, which can help businesses choose a reliable supplier, such as the Cut to Size experts.
Outsourcing As A Strategic Manufacturing Decision
CNC machining outsourcing does not have to replace a company’s internal manufacturing operations. Instead, it should be treated as a support system for pre-existing capabilities by providing access to specialist expertise, extra or more advanced equipment and additional capacity whenever required.
By taking this broader view can make outsourcing a strategic manufacturing choice rather than simply a way to reduce short-term costs.
