"Heavy cutting" usually refers to the process of making deep cuts or removing large amounts of material from the workpiece. In CNC machining centers, heavy cutting may involve high-speed, efficient cutting operations, typically used to machine harder, larger workpieces. The following are some aspects related to heavy cutting on CNC machining centers:

1. Tool selection:

Heavy cutting usually requires the selection of tools with good wear resistance and high rigidity. Carbide cutting tools, coated cutting tools, etc. are common choices to ensure that the cutting tools have a long service life in high-load, high-speed cutting.

2. Cutting parameter settings:

Parameters such as cutting speed, feed speed and cutting depth need to be set appropriately according to the specific workpiece material, shape and machine tool performance. Optimized cutting parameters increase productivity and reduce tool wear.

3. Machine tool stability:

During heavy cutting processes, machine tool stability is crucial to ensure high precision and surface quality. High rigidity and high stability CNC machining center can reduce vibration and improve machining accuracy.

4. Cooling system:

Since heavy cutting generates more heat, an effective cooling system is necessary. Coolant can cool the tool and workpiece, lower the temperature, reduce thermal deformation, and improve machining accuracy.

5. Accuracy of CNC system:

The accuracy and stability of the CNC system have a great impact on the quality of the workpiece during heavy cutting. The precise CNC system can ensure the accuracy of the cutting trajectory and improve the processing accuracy.

6. Workpiece fixation:

During heavy cutting, it is crucial that the workpiece is firmly held to prevent vibration and deformation. Proper fixtures and workpiece mounting methods are important to maintain workpiece stability.

7. Tool monitoring system:

Some advanced CNC machining centers are equipped with tool monitoring systems, which can monitor the wear of tools in real time and remind operators to replace tools in time to ensure stable processing quality.

Heavy cutting is usually used in scenarios that require high-efficiency processing, large amounts of material removal and deep processing, such as aerospace, automotive industry, mold manufacturing and other fields.
