CNC Cutting Drilling Milling Proessing Machine

1:Machining Solution
Based on the workpiece you provided, our proposed solution is as follows: automatic feeding-vertical drilling and chamfering (servo-driven forward and backward movement)-tapping-automatic cutting. The cut surface is smooth and free of burrs. Feeding and cutting lengths are accurate to ±0.1. Approximately 10 finished products are produced per minute.
1: The automatic feeding section uses a servo motor to drive a ball screw (slide module) for feeding. The lower mold of the automatic machine must be custom-made according to the workpiece's machined base surface to ensure the workpiece is placed flat on the table. The automatic profile feeding section is equipped with pneumatic vertical and horizontal clamps. The automatic feeding section features a material level sensor; when no profiles are present, the machine automatically stops in place and waits for manual loading. After loading, pressing the automatic start/stop button initiates the next automatic machining cycle. This machine features a zero-scrap function. The newly loaded aluminum profile pushes the remaining short section of aluminum profile forward. Only at the joint between the two profiles is there 1–2 workpiece widths of scrap material. This significantly reduces aluminum profile scrap.
2: The second step involves drilling and chamfering; the servo feeding mechanism advances the material by one workpiece width. A high-speed spindle motor mounted vertically drives a custom milling cutter. This mechanism is equipped with a movable servo motor mounted horizontally that drives the drilling motor to move back and forth, enabling the drilling of two holes. The rear drill uses a custom milling cutter to drill the holes, and the depth of the spindle motor's forward movement is controlled by the servo motor, which effectively regulates the depth of the chamfer. Sensors are installed on the drilling mechanism. The machine can only proceed to the next step if all operations are functioning normally.

The third step is tapping: a tapping device is installed on the parallel side of the rear drill. After drilling is completed, it can move forward to tap the small holes of the workpiece, while a vertical tapping mechanism is set up to tap the large holes.

3: Step 4-Cutting: The servo feeding unit advances the material. The spindle motor drives the saw blade. The sawing process is completed through linear guide rail movement. The workpiece hole position can be fine-tuned by adjusting the sawing movement.

The machine executes actions 1-2-3-4 simultaneously, with each movement (forward or backward) detected independently. It features automatic fault detection: if any action is incomplete, the machine halts, and the faulty component is displayed in Chinese characters on the operation screen, allowing manual troubleshooting.

 

Technical Description: This machine is a custom model. The steel frame of the bed is precision-cut using mechanical cutting equipment. After welding, the bed undergoes aging treatment and planarization before reassembly, ensuring a robust and deformation-free foundation. Certain components are meticulously ground on a grinding machine and planed on a milling machine to guarantee workpiece flatness, providing a solid basis for precise assembly.

 

 

3. Step 3: Tapping. A tapping device is positioned parallel to the rear drill; once drilling is complete, it moves forward to tap the small holes in the workpiece. A tapping mechanism is positioned vertically to tap the large holes in the workpiece.


3: Step 4: Cutting. The servo feed mechanism advances the workpiece. The spindle motor drives the saw blade, which moves back and forth to complete the cut. The sawing section uses linear guides for forward and backward movement during cutting. The positioning of the workpiece holes can be fine-tuned by adjusting the sawing movement.
Operations 1–2–3–4 are performed simultaneously, with separate detection for the forward and reverse movements of each operation. The machine features an automatic fault detection function: if any operation is not completed, the machine stops, and the location of the fault is displayed in Chinese characters on the operation screen, allowing the operator to troubleshoot the issue accordingly.
