How to Program on CNC Milling Machine?

A CNC drilling and milling machine is designed for precision machining of aluminum profiles, including drilling, slotting, routing, tapping, and contour milling. It is widely used in the production of aluminum windows, doors, curtain walls, and industrial profiles.

1. How to Program the CNC Drilling and Milling Machine

The machine adopts HAN'S SCM system and can be programmed in the following ways:

(1) Manual Programming (G-Code)

Operators can directly input standard G-code commands to define:

• Hole position (X, Y, Z coordinates)

• Milling path

• Feed speed

• Spindle speed

• Tool selection

This method is suitable for simple operations such as:

• Standard round holes

• Straight slots

• Rectangular openings

(2) CAD/CAM Software Programming

For complex shapes, profiles can be designed in CAD software and converted into machining programs via CAM software. The program is then imported into the CNC system via:

• USB interface

• Network connection

This method ensures:

• High precision

• Reduced manual errors

• Faster batch production

(3) Window & Door Software Integration

The machine can be connected to professional window and door optimization software. After entering profile parameters, the system automatically generates machining programs, improving production efficiency and accuracy.

2. Machining Various Shapes

The CNC drilling and milling machine can process different shapes through multi-axis control:

● Round Holes

By circular interpolation (G02/G03), precise round holes of different diameters can be machined.

● Slots

Straight slots, long holes, and drainage slots can be milled accurately by setting length, width, and depth parameters.

● Rectangular Openings

The tool follows a defined rectangular path to create lock holes, hardware installation openings, etc.

● Irregular Contours

With CAD/CAM programming, the machine can process:

• Arc shapes

• Special-shaped openings

• Complex hardware installation holes

● Tapping

Thread tapping can be completed automatically with controlled spindle speed and feed synchronization.
