When glass is being used in a technical application, standard shapes and sizes are not always suitable. Many industries require components that have been manufactured to specific dimensions, tolerances and designs, making precision machining an important part of the production process.
CNC machining has become an important technology within modern glass manufacturing, allowing complex components to be produced accurately and consistently. At Newcastle Optical Engineering, we combine CNC technology with years of specialist experience to manufacture bespoke glass and quartz components for customers across a wide range of industries.
What Is CNC Glass Machining?
CNC stands for Computer Numerical Control. CNC machinery uses programmed instructions to control the movement of cutting and machining equipment, allowing materials to be processed to highly specific dimensions.
When working with glass, accuracy is particularly important. A component may need to fit precisely within a larger assembly or meet specific dimensional requirements for an optical, scientific or industrial application.
Using CNC technology allows manufacturers to follow detailed drawings and specifications while maintaining consistency throughout the production process. This is particularly useful when producing multiple components that need to meet the same requirements.
Creating Complex Glass Components
One of the major benefits of CNC glass machining is the ability to create shapes and features that would be difficult to produce using conventional methods.
Glass can be cut, ground, milled and machined to create bespoke components for specialist applications. Complex designs can require carefully controlled machining processes to achieve the required dimensions without compromising the quality of the finished component.
At Newcastle Optical, our CNC capabilities include optical centring and grinding for complex glass components. We can work from customer drawings and specifications to produce components designed around the requirements of a particular project.
Precision Matters in Optical Engineering
In precision optical engineering, even relatively small variations can affect how a component performs.
Dimensions, flatness, thickness and surface quality can all be important depending on the application. This is why precision manufacturing involves much more than simply cutting a piece of glass into a particular shape.
Our manufacturing processes include glass cutting, grinding and machining, alongside lapping and polishing. We can work with components ranging from very small parts through to larger pieces, depending on the material and requirements.
Combining these processes allows us to control the component throughout its manufacturing journey rather than treating machining as an isolated stage.
CNC Machining for Bespoke Applications
Not every project requires an off-the-shelf component. In fact, many of the industries we work with have highly specific requirements.
Our bespoke glass components are used across sectors including laser technology, semiconductor manufacturing, engineering, energy, electronics, oil and gas, medical and healthcare, aerospace, automotive and academic research.
Each industry can have very different requirements. A laboratory component may need to meet different specifications from a component used within a laser system or industrial machine.
This is where working with an experienced precision glass manufacturer can be particularly valuable. By discussing the intended application at the design stage, it is possible to consider the material, dimensions, machining requirements and finishing processes before production begins.
Choosing the Right Glass Material
The machining process is only one part of producing a successful component. The material itself also needs to be suitable for the application.
Newcastle Optical works with a wide range of specialist glass and quartz materials, including quartz, Spectrosil® ultra-high purity fused silica, borosilicate, BK7™, Robax™, soda lime and a range of coated glass products.
Different materials have different characteristics, including thermal resistance, optical transmission, chemical resistance and thermal expansion. Selecting the appropriate material can therefore be an important part of the manufacturing process.
Our team can provide design and production advice to help customers identify an appropriate solution for their requirements.
From Cutting to Finishing
CNC machining can form an important part of a wider manufacturing process. Depending on the component, additional processes may be required to achieve the required finish and performance.
These can include lapping and polishing, chamfering and bevelling, coating and glass tempering. Inspection and certification are also available, with components checked for dimensional accuracy, flatness and quality imperfections.
By bringing multiple processes together, we can manufacture precision components to bespoke specifications while maintaining control over quality throughout production.
