Defence Procurement: Why JOSCAR, AS9100 and Supply Chain Assurance Matter
Defence procurement involves more than purchasing components that meet an engineering specification. Buyers must also consider the reliability of their suppliers, the effectiveness of manufacturing controls and the ability of the wider supply chain to meet contractual...
Inside the Part: CNC Machined 7075 Aluminium Cylinder for Pipeline Pigging
Precision engineering is used in some very different environments, and this latest component takes us inside an area of industry that many people outside the pipeline sector may never have encountered: pipeline pigging. For this project, Tarvin Precision manufactured...
Precision CNC Machined Components for Defence: Materials, Tolerances and Traceability
Modern CNC machining offers a flexible approach to producing components for demanding engineering applications. CNC milling, turning and multi-axis machining can be used to manufacture a wide variety of geometries, often involving close tolerances, multiple features...
Inside the Part: CNC Machined Brass Anode Hooks for Electroforming
Not every precision-machined component needs complex geometry to perform an important job. Sometimes the most interesting parts are those that appear relatively simple but have been designed for a very specific purpose within a much larger manufacturing process. These...
Choosing a JOSCAR-Registered CNC Machining Supplier for UK Defence Projects
Selecting a CNC machining supplier for defence projects involves more than comparing component prices and manufacturing lead times. Procurement teams must consider technical capability, quality management, traceability and the reliability of the wider supply chain....
AS9100-Certified CNC Machining for Defence Components: Why Quality Standards Matter
Manufacturing precision components for defence applications requires more than the ability to produce parts within specified dimensions. Consistent quality, controlled production processes and reliable inspection records all contribute to ensuring that components meet...
Tarvin Precision Meets Future Engineers at Coleg Cambria Work Experience Showcases
Last week, the Tarvin Precision team attended two Coleg Cambria Work Experience Showcases, visiting the Wrexham campus on 23 September and the Deeside campus on 24 September. The events were a great opportunity to meet students considering a future in engineering and...
Clearance, Transition and Interference Fits: A Guide for CNC Machined Parts
When two precision-machined components are designed to fit together, their nominal dimensions only tell part of the story. What really determines how the parts assemble is the relationship between the tolerances applied to the mating features. A shaft nominally...
Precision at Every Step: New CMZ CNC Machine Arrives at Tarvin Precision
There was a sizeable new arrival at Tarvin Precision this week as the latest addition to our machining capacity made the journey from Bilbao in Spain to our facility in North Wales. Our new CMZ TA Series CNC machine was transported directly by CMZ, leaving Bilbao...
Inside the Part: CNC Machined Stainless Steel Components for a Mass Spectrometer
Scientific instruments often depend on small, highly controlled components that are easy to underestimate from a photograph alone. For this project, we manufactured a batch of CNC machined stainless steel 304L components for use within a mass spectrometer. The parts...
Surface Finish Ra Explained: What Designers and Buyers Need to Specify
Surface finish is an important consideration on many CNC-machined components, but it is also an area where drawings can easily become more restrictive than necessary. A surface that looks visually smooth is not necessarily suitable for every function, and a surface...
