What is CNC Machining?
CNC (Computer Numerical Control) Machining is a manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery. It’s used to control complex machines that perform a variety of functions, such as drilling, turning, milling, and routing. CNC machining allows for precise and repeatable production of parts by controlling the movement of machines along multiple axes to cut or shape materials to exact specifications.

CNC Preparation Work
Pre-processing
CNC Program Setup
Before starting the CNC machining process, a detailed CNC program is developed to ensure the precise movement of tools and workpieces. The program defines the cutting paths, speeds, and depths, tailored to the specific design and material.
Pre-processing
Fixture and Tool Inspection and Calibration
During the preparation phase, the necessary fixtures and cutting tools are thoroughly checked and calibrated. This ensures proper alignment and functionality, allowing for accurate and efficient machining.
In-process
Machine Adjustment and Self-inspection
During the machining process, operators continuously monitor and adjust the machine settings as needed to ensure that the cutting operations are precise. Self-inspection is performed at regular intervals to verify that each part meets the required specifications before proceeding to the next step.

Different Types of CNC
CNC Milling Services
CNC milling is a precise manufacturing process where a computer-controlled machine removes material from a workpiece. Guided by a computer program, the cutter's movement is highly accurate and repeatable. CNC milling is ideal for creating complex shapes and designs, making it widely used in aerospace, automotive, and medical industries where precision and consistency are critical. This process enables manufacturers to produce high-quality parts with minimal waste and maximum efficiency.
CNC Turning Services
CNC turning is a machining process where material is rotated against a cutting tool to remove material from a workpiece. This process is ideal for creating cylindrical or round parts, such as shafts, rings, and other rotationally symmetrical components. Computer-controlled instructions guide CNC turning, ensuring precise, repeatable cuts and smooth surface finishes. This process is highly efficient, allowing for rapid production of complex designs with tight tolerances. CNC turning is commonly used in industries like automotive, aerospace, and medical manufacturing, where high-quality, accurate components are required.
