What is Precision Machining?

Precision machining is the process of manufacturing components with extreme accuracy. This is to ensure that the end product meets engineering requirements. It complies with specifications to produce accurate dimensions, tolerances, angles, surface finishes, and much more.

It involves using precision machine tools such as lathes, turning centers, grinding machines, milling machines, drill presses, and rotary tables. These machines are capable of working with different materials to produce high-quality components.

They work by removing excess material from the stock material following CAD/CAM design fed into the computer system. This ensures that only the required parts remain for further operations such as drilling, deburring, and much more.

We offer complete precision machining services that include CNC Milling, CNC Turning, Wire EDM (Electrical Discharge Machining), Precision Grinding, Laser Cutting / Engraving, Stamping & Forming, and custom fabrication & welding.

What are the Advantages of Precision Machining?

Precision machining provides several advantages. These include:

  • Higher Productivity. Using computerized machines in this process ensures higher productivity because of optimized operations. It uses various techniques to remove excess material from the stock in the most efficient way possible. The less engagement of humans eliminates errors.
  • Accurate results. Precision machining ensures accurate dimensions, tolerances, and finishes. This is because it uses advanced machining techniques that maintain consistent levels of accuracy throughout the manufacturing process. With the right machine, you can achieve tolerances as low as ±0.0001”.
  • Fewer Materials Wastage. The process of precision machining uses less material as compared to conventional methods such as casting and forging. It removes excess material during the machining process to increase efficiency and reduce production costs.
  • Increased Turnaround. The computerized machines used in this process are faster than the manual ones. They work on CAD/CAM designs to speed up operations, increase productivity, and reduce lead times.
