What is CNC Machining

CNC machining is a manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery. The process can be used to control a range of complex machinery, from grinders and lathes to mills and routers. Common CNC machines include 3-axis, 4-axis, and 5-axis milling machines, lathes, and routers.
At Karkhana, our  CNC machining facilities are designed for both rapid prototyping and low-volume production of end-use components. We help you with selecting right material and providing the best way to optimise the design. CNC machines can cut almost any metal alloy and rigid plastic with high precision and repeatability, which makes CNC machined parts suitable for nearly every industry

Applications of CNC Machining

Rapid Tooling

CNC machining can cut a high variety of fully dense, durable materials like aluminum 5-series and stainless steel, making it the perfect process for creating fixtures or molds. CNC machining finds application in prototyping and production, practically in every industry. It helps to create everything from aircraft parts to surgical tools.

CNC machining in the automotive industry

The automotive industry regularly enjoys the use of CNC machining for both prototyping and production. Extruded metal can be machined into cylinder blocks, gearboxes, valves, axles, and various other components. On the other hand, CNC machined plastics find usage in dashboard panels and gas gauges.The creation of various replacement parts is also possible with CNC machining. This is because the turnaround times are fast, and there is no minimum required part quantity.

CNC Machining in Aerospace

The machining of metal aircraft components occurs at the highest level of precision. This is highly essential for safety-critical applications. Also, the range of engineering metals compatible with CNC provides aerospace engineers with plenty of options.
The applications of CNC machining in the aerospace industry are wide and reliable. Some of the machinable aerospace components include engine mounts, fuel flow components, landing gear components, and fuel access panels.

CNC Machining in Consumer Electronics

CNC machining also helps in the prototyping and production of consumer electronics. These electronics include laptops, smartphones, and many others. The chassis of an Apple MacBook, for example, is CNC machined from extruded aluminum and then anodized.
In the electronics industry, CNC machining helps to create PCBs, housings, jigs, fixtures, and other components.

CNC Machining in Medical

CNC machining can be used on various medically safe materials. Since the process is suited to one-off custom parts, it has many applications in the medical industry. The tight tolerances afforded by CNC machining are essential to the high performance of machined medical components.
CNC machinable medical parts include surgical instruments, electronic enclosures, orthotics, and implants.
