CNC Machining Services - Precision Engineering at Leussink

Q: What is CNC Machining and How Does it Work?

The CNC machining process involves the use of computer-controlled machines to define and manufacture a diverse range of parts. CNC has revolutionised the manufacturing industry, enabling manufacturers to produce complex parts with high levels of accuracy and repeatability. Creating CNC-machined parts includes: CAD design – Used to design a 2D or 3D digital model. CAM programming – Used to translate the model to a CNC-compatible code that specifies the operations needed to manufacture the part. Machining – CNC operator secures the workpiece and installs the correct cutting tools. The CNC machine then follows the steps outlined in the programme to produce the finished product. Quality control – The operator carefully inspects the part for quality and accuracy.

Works to truly exact specifications

Precisely manufactures any type of part required

What is CNC Machining?

Computer Numerical Control (CNC) machining is a precision manufacturing process that uses advanced technology to cut, shape, and finish materials with exceptional accuracy. Using either a CAM (Computer-Aided Manufacturing) or a CAD (Computer-Aided Design) file, CNC machines take the instructions from these files and use them to create a finished product from raw materials to exact specifications.

Truly taking the guesswork out of parts production, utilising CNC machinery enables our skilled engineers to provide highly detailed parts with a level of quality that’s unrivalled in the industry, achieving tolerances as tight as ±0.001mm. Read our guide to engineering tolerances for more detail about our precision CNC machining services.

Our CNC Machine Services

Leussink is your go-to CNC machining services manufacturer for complex prototypes, custom components, and production runs. Whether you need rapid prototyping, low-volume manufacturing, or specialised machining, our skilled team provides accurate, high-quality parts to meet your exact specifications.

CNC Milling

One of the most common examples of CNC machining is CNC milling. Our advanced CNC milling machines in Australia are multifaceted, meaning they can achieve many operations undertaken by cutting and drilling machines, yet with some notable differences. For example, the cutter in a CNC milling machine can move along multiple axes, meaning it can create a variety of shapes, slots, and holes.

Ideal for producing a wide variety of components, CNC milling services are perfect for prototyping and short-run production of complex parts that require meticulous attention to detail.

Our process: Leussink has state-of-the-art CNC milling facilities and equipment, as well as highly skilled and experienced staff to cater to all our clients’ needs. We program each job from your CAD or CAM file, run a first-off inspection before full production, and machine on our own multi-axis mills, including our Zayer Memphis 4000, the only one in an Australian job shop.

CNC Turning

CNC turning machines can deliver on your project in various ways, depending on the machine and your specific requirements. Also known as ‘subtraction machining,’ CNC turning involves the removal of material to reveal the part within. Leussink’s CNC turning machines are capable of working on round, square and hexagonal shapes, to name a few. Our advanced equipment can accommodate multiple tools, providing more options for complex parts.

Our machines offer various tooling and spindle options, as well as outer diameter limitations and versatile power and speed capabilities. Being able to offer our clients variety means we can create the parts you need to your exact specifications and tolerances.

Leussink’s engineers and machinists possess the experience, training, and expertise to create a solution that is both economically efficient in terms of time and cost, without compromising on quality.

Our process: We run turning jobs across our Okuma LB300, LB3000, LH55 and LB4000 lathes, so we can match the right machine to your batch size, from a single prototype part to a full production run.

Wire Cutting

When you need to produce high-volume parts to tight tolerances, CNC wire cutting can consistently deliver quality and accuracy. The intricacies that a CNC wire cutting machine can achieve enable it to produce items with a diameter measured in the thousands of an inch, all the way up to measurements of several inches.

Aside from being able to complete projects requiring the most detailed measurements, the versatility in cutting conductive metals of various hardnesses is remarkable. From copper to molybdenum and tungsten, a CNC wire cutting machine can easily cut these materials, reducing production times and associated costs for producing the parts.

Our process: As with any engineering service we offer, Leussink will work closely with you to determine your needs and objectives, and then assess whether CNC wire cutting is the best option for you. However, if this element is just part of a larger project, we can incorporate it into a fully tailored solution. We typically use wire cutting for the fine, complex profiles that milling or turning can’t reach, then hand the part straight to our inspection team for final sign-off.

Surface Grinding

Surface grinding of precision components is another important part of the manufacturing process. While this element of the process has traditionally required the most manual control of any step in the production process, technological advances have now enabled surface grinding to be automated via CNC. Where once a skilled grinder would manually labour over every individual piece to ensure a high finish, Leussink’s CNC grinders can provide a high-quality finish that is friction-resistant, at a speed and quantity that was previously unachievable.

Our process: CNC surface grinding machines are loaded with either a CAD or CAM file, which provides precise grinding instructions and ensures each item meets the exact tolerances and specifications outlined in the original design. Leussink will run tests to ensure that specifications are accurate and meet your expected level of quality. We check surface finish against your drawing before the part leaves our workshop, so what you receive matches what you specified.

Get a CNC Machining Quote

Leussink provides free quotations for the machining of your part and can offer ‘do and charge’ and contract work arrangements.

‘Do and charge’ – A popular arrangement with many of our repeat customers, this allows the value of the part to be calculated in terms of the time taken to produce it, plus the cost of materials, to give a final fixed price. This allows for quicker turnaround times because there is no need to wait for a quote. If getting your machine back up and running is more important than getting a quote before any work is done, then ‘do and charge’ is the right option for you.
Contract work – This arrangement guarantees a fixed price for a specified period of time, which may include pre-manufacture and storage of stock in our warehouse.

Once you get in touch, our process is straightforward:

Send your drawings, CAD file, or sample part.
We review the job and confirm a fixed quote, a do-and-charge, or contract arrangement.
Our engineers machine the part on the CNC equipment suited to the job.
We inspect the finished part against your specifications before it leaves our workshop.

Whichever arrangement suits your needs, get in touch to request a CNC machining quote today.
