Precision Machining Services

Process Overview – It is a process that creates a desired shape and size by removing the unwanted material from a larger piece of metal i.e Subtractive Manufacturing. A plethora of machining options are available depending on the part geometry, profile to be achieved, GD & T requirements, surface finish, throughput etc. CNC (Computer Numerical Controlled) machining is a widely used manufacturing process that uses automated high-speed cutting tools to form a particular feature from metal or plastic. CNCs are generally classified as 3-axis, 4-axis and 5-axis based on the movement of part and tooling along the axis. Different machines have different working mechanisms such as : a) workpiece securely clamped while the tool moves b) tool may remain in place while the workpiece moves c) both the cutting tool and workpiece move together.

Application and Benefits

• We supply machined components to almost all industry sectors in batch and mass production quantities. The design and functional characteristics of the part are fixed based on its end application. Selection of the material is done to sustain the working environment and machined to accurate dimensions to ensure proper fit and assembly.

• Usually, Aerospace engine parts are made from Titanium, Tantalum and Nickel based alloys which exhibit high strength, low weight and high temperature fatigue resistance

• Similarly, parts used in Oil & Gas and Power Generation sectors are made from Nickel, Chrome and Cobalt based alloy steels which exhibit high wear and corrosion resistance

• Few key benefits of machining include :

  • Rapid Tooling – A variety of materials can be machined to achieve accurate dimensions for making fixtures and molds.

  • Rapid Prototyping – Flexibility of manufacturing small scale prototypes saves a lot of time, money and effort and enables to conduct a detailed part validation and risk assessment

  • Production – Reliability and Repeatability of machining can be ensured by application of advanced process control techniques which enables mass production

  • Customization – Wide range of advanced manufacturing techniques increases the scope of customization for new part development
