What is Rough CNC

Rough CNC is a machining process performed on CNC machine tools where the main goal is to quickly remove most of the machining allowance from the workpiece so that the workpiece is close to its final shape.

The standard for tool blunting in rough machining is generally a significant increase in cutting force, that is, the wear degree of the tool face is used as the basis for judgment.

The process of rough CNC is usually the first stage of the CNC machining process, which allows for more precise and efficient finishing operations later in the machining process.

Rough machining CNC is an important processing method. It can effectively improve production efficiency, reduce labor input, and ensure the processing quality of workpieces to a certain extent.

What you need to pay attention to when doing CNC rough machining

1. Choose a larger feed rate and the largest possible cutting depth to remove as many chips as possible in a short period of time.

2. Since the requirements for surface quality are not high, the standard for tool blunting is generally a significant increase in cutting force.

CNC rough machining to manufacture injection molds

CNC rough machining plays an important role in injection mold manufacturing, helping mold manufacturers improve production efficiency and product quality.

CNC rough machining is mainly used for the preliminary processing of injection molds, which can quickly obtain the basic shape and size of the mold and eliminate burrs and flash.

The advantage of CNC roughing is its efficiency. It can greatly improve the efficiency of mold processing and manufacturing, especially when processing a large number of identical molds. The advantages of CNC rough machining are particularly obvious.

CNC rough machining also faces some challenges. What is pursued during rough machining is high speed, high removal rate, and low machining accuracy, and the accuracy damage to the equipment during rough machining is the most serious. Therefore, in order to control the processing quality of products, mold manufacturers need to regularly inspect and repair CNC equipment, clarify the processing accuracy of each equipment, and clarify the processing tasks of each equipment.

Rough machining CNC cost

Rough machining CNC costs need to be calculated based on factors such as the size, shape, steps, and factory equipment of the processed products. The processing price mainly depends on the following factors:

1. Material cost This is fixed, usually based on the unit price of the product multiplied by the weight of the incoming material (above 20Kg).

2. Equipment cost Including the cost of leasing or purchasing CNC machine tools, as well as the cost of equipment maintenance and upkeep.

3. Processing costs Calculated based on the hourly cost of equipment required for each process.

4. Loss Including material loss and equipment loss.

5. Other expenses Packaging and transportation, administrative expenses, tooling tools, profits, etc.

The above is only a rough calculation method, and the specific costs need to be adjusted according to the actual situation. If you want to get a more accurate quotation, you can contact us at Universe Plastics for consultation.
