Whats CNC Milling

CNC milling is one of the Subtractive machining types.

CNC milling is a manufacturing process that uses a cutting tool mounted on a rotating spindle to selectively remove material from a block , involves mounting the workpiece on a CNC machine bed and cutting materials from a block to products made of metal, and plastic materials.

The workpiece is rigidly mounted to a table, and this table moves or rotates on different planes so the tool can work at many angles. Sophisticated CNC milling machines can have 3,4,5 or more axis of independent motion to make more complex features or to avoid having to move the workpiece to a separate machine.

Why Choose CNC Milling at PROTO MFG

1. Reduced Labor Costs;

PROTO MFGS CNC milling is hugely controlled by a software program and requires very little human interaction apart from the initial setup and data feeding. CNC milling also demands less advanced training, further reducing labor costs. With computers playing a major role, the chances of human error and compromised workplace safety are also reduced by a high percentage.

2. Flexible Production Quantity;

PROTO MFGS CNC Machines are built to provide maximum accuracy whether they are tasked to produce one metal machined part or thousands of machined parts.

3. Tight Tolerance

PROTO MFGS tolerance Can be 0.005 to 0.01 mm

4. PROTO MFGS ability to Produce Complex Parts

5.PROTO MFGS works for a wide range of Material Type

6. PROTO MFGS CNC milling Suitable for a wide range of industries, including automotive, aerospace, medical device, robotics, construction monitoring equipment, and agriculture equipment
