CNC machining might sound complicated, but it’s something we use every day at Polgain. If you’re not familiar with it, don’t worry. We’ll talk you through exactly what it is, how it works, and why it’s such a big part of manufacturing today.
What is CNC machining?
CNC stands for Computer Numerical Control. Put simply, it means machines are controlled by computers, not by hand. Instead of manually controlling a tool, a computer guides the machine to cut and shape materials exactly as planned.
Think of CNC machining like using sat-nav in your car. You program the route once, and your car takes you exactly where you need to go, every time. CNC machines do something similar. Once programmed, they produce identical parts over and over, perfectly matching your design.
At Polgain, CNC machining helps us deliver precise parts consistently, whether we’re making a single component or hundreds at a time.
What can CNC machining make?
CNC machining can make nearly anything, from straightforward items to intricate parts that need very exact measurements. At Polgain, we regularly produce parts for industries including automotive, pharmaceuticals, power generation, packaging, and heavy engineering.
It’s ideal for creating gears, shafts, camshafts, and custom-designed components. If you have a part that’s worn out or no longer available, we can use CNC machines to make exact replacements. By measuring the original piece, we can recreate the design digitally, then produce a brand-new part that fits perfectly.
How CNC machining works
CNC machining starts with a digital design. Our engineers create a detailed computer model of the part we need to make. That design gets translated into instructions that the CNC machine follows precisely.
The main types of CNC machining we use at Polgain include milling, turning, and grinding. Milling involves cutting and drilling materials into precise shapes. Turning is used for creating round parts like shafts or valves by spinning the material against shaping tools. Grinding finishes parts to exact dimensions and smooths surfaces, ideal for precision components like cams.
Together, these processes allow us to create highly accurate, reliable parts quickly and efficiently.
Why CNC machining is useful
Manufacturers use CNC machining because it solves common production problems easily and reliably. CNC machining provides excellent accuracy and consistency, making quality control straightforward. It also boosts efficiency, speeding up production significantly. Precision control reduces errors and material waste, and CNC machines are adaptable enough to handle different materials and easily switch between projects.
CNC machining at Polgain
CNC machining isn’t just another service we offer; it’s central to our work at Polgain. Our engineers use modern equipment and expertise to deliver dependable, high-quality parts every day.
We have particular expertise in precision Cam and camshaft manufacturing. Our specialised CNC Kopp and Landis grinding equipment shapes Cams and camshafts that perform exactly as they need to, right down to the smallest detail. We can also refurbish older Diesel camshafts to their original condition, offering a cost-effective alternative to buying new.
If you come to us with a detailed drawing, an existing part, or simply an idea, our engineers will help turn it into a finished component that meets your requirements exactly.
Industries benefiting from CNC machining
Any industry needing reliable and precise components can benefit from CNC machining. Automotive companies rely on us for engine components like camshafts. Pharmaceutical Tabletting Press businesses depend on us for parts. Power generation, the Marine and Pumping Sectors require durable parts. Can Making and packaging firms need precision-engineered parts for efficient machinery.
From heavy-duty industrial applications to highly specialised components, CNC machining provides a practical, reliable solution.
