CNC Machining Service

One drawing, one supplier, and access to over 200 machines behind it: lathes, mills, grinders, EDM and tapping.

We hold tolerance across the whole batch, not just the first off sample. Parts are inspected against your drawing before they leave the building, and the records stay on file.

There is no minimum order quantity, so a single prototype and a production batch run through the same process and the same inspection. Send a drawing or a sample and we will quote the part, the material and the lead time.

CNC Milling and Turning at Coler

You hand over the drawing and we manage the rest: programming, fixturing, machining, inspection and any secondary operations. One supplier, one purchase order, one delivery date.

Tell us the tolerance that matters and the quantity you need, and we will quote against the drawing rather than around it.

Decades of industry experience

We provide comprehensive services that encompass intelligent painting, silk-screen, transfer painting, laser etching, as well as assembly and packaging services.

Material and tolerance drive the price harder than size does. The same shape in stainless held to 0.01mm costs multiples of aluminium held to 0.1mm.
Features that need a second setup add cost. Mark the faces that have to be true to each other and we will plan the operations around them.

Every job runs to a schedule you can see. You get a lead time with the quote, and we tell you if it moves.

Our experienced Quality Control (QC) department upholds stringent quality standards, guaranteeing that all projects and product data are meticulously recorded and can be traced within our system.

What decides the cost of a machined part

Our engineers review your drawing before we quote and flag the features that will add cost, while there is still time to change them.

Our engineering personnel come with more than 30 years of industrial manufacturing expertise.

Fixturing is where the time goes on low volumes. Tell us the quantity up front and we will choose between a soft jaw setup and a dedicated fixture.

We machine aluminium, steel, stainless, brass, nickel alloys and engineering plastics, from single prototypes through to production batches.

What is CNC Machining?

CNC machining, or Computer Numerical Control machining, represents a cornerstone of modern manufacturing technology. It is a process that utilises computers to control machine tools, including lathes, mills, routers, and grinders. The essence of CNC machining lies in its ability to produce complex and intricate parts with high precision, a task that is challenging and often impractical with manual machining.

The journey of CNC machining begins with the creation of a design. This design is usually developed using Computer-Aided Design (CAD) software. This digital model serves as a blueprint for the CNC machine, detailing the dimensions and characteristics of the desired part. The CAD file is then converted into a CNC program using Computer-Aided Manufacturing (CAM) software. This program essentially translates the design into instructions that the CNC machine can understand and execute.

Setting up the CNC machine is a critical step in the process. This involves preparing the workpiece, the piece of material that will be machined into the final part, and securing it in place. The appropriate tools are then installed into the machine, such as drill bits or lathe tools, depending on the operation to be performed. Once everything is set up, the CNC program is loaded, and the machine is ready to start the machining process.

One of the most significant advantages of CNC machining is its precision. The computer-controlled nature of the process allows for extremely tight tolerances, often down to fractions of a millimetre. This high level of accuracy is essential in industries like aerospace and medical devices, where the dimensions and specifications of parts are critical.

Another benefit of CNC machining is its versatility. The same equipment can be used to produce a wide variety of parts, ranging from simple to highly complex geometries. This flexibility is invaluable in custom manufacturing or in situations where a range of different parts is needed in small quantities.

CNC machining also offers a high degree of repeatability. Once a program has been created and tested, it can be used to produce parts that are virtually identical, time after time. This consistency is crucial in mass production settings, where ensuring uniformity across batches of parts is essential.

The speed and efficiency of CNC machining are further advantages. What might take hours to accomplish manually can often be done in minutes with CNC machining. This efficiency not only reduces production time but also minimises waste, as the precision of CNC machining leads to more efficient use of materials.
