CNC Milling
CNC milling is a computer-controlled, subtractive machining process that uses rotating cutting tools to remove material from a solid, stationary workpiece in order to create custom-designed parts. During the milling process, the workpiece is cut along a number of axes to achieve a variety of shapes and geometries. CNC mills can be used for cutting and machining operations of various plastic and metal materials. It is used to manufacture irregular shape products or prototypes. It is widely used for many industries that requires precision components and is also an ideal tool for making molds.

Quick turnaround provide us great competence against others. We also have a variety of surface finish options so that your CNC machined part is exactly what you need it to be.
3-Axis CNC Milling Service
3-axis CNC milling is one of the most widely used techniques to make mechanical parts. For decades, it has been well known to manufacturers and other players in the industrial sector, as well as in many other domains like architecture, design, and art.
3-axis milling is a relatively simple process, using conventional machining tools like the milling machine, which allows the material to be worked on 3 axes (X,Y and Z). The machining tool then proceeds to remove shavings in three basic directions corresponding to the axis of a flat surface. It involves cutting a stationary workpiece along three linear axes: left-to-right, back-and-forth, up-and-down. Easy to program and operate, 3-axis mills are effective for simple geometric designs and can be used for a wide variety of parts because it is fast and cost-effective.
5-Axis CNC Milling Service
5 axis milling involves all the axes of 4 axis milling, with an additional rotational axis. 5 axis milling machines are the best CNC milling machines available today, capable of creating precise and intricate parts for artificial bones, aerospace products, titanium pieces, oil and gas machine parts, car molds, medical, architectural, and military products.
For some complex internal design or models with multi irregular surface design, we will use 5 axis CNC milling machine to produce, to improve the overall accuracy and reduce the processing time and cost.
