CNC Grooving Tools: Types, Working Principles and Uses

CNC grooving tools are commonly used in the metalworking and fabrication industry. They come in different types, with varying working principles and uses, as detailed in this article.

Definition and uses of CNC grooving tools

The CNC grooving tool is a type of tool used for grooving on CNC machines. It is a specialized tool for cutting slots or grooves.

Working principle of CNC grooving tool

The working principle of a CNC grooving tool is that the tool is controlled by the program on the CNC machine. The tool follows a path and depth that is set in the program, and then rotates and feeds itself while cutting the workpiece material to create the desired groove.

Common CNC grooving tool types

Common CNC grooving tool types include:

– Straight edge grooving cutters: used to cut straight grooves.

Advantages of CNC grooving tools

Compared to traditional grooving tools, CNC grooving tools offer various advantages.

CNC grooving tools offer several advantages, including high precision, efficiency, multifunctionality, a high degree of automation, and consistency. These tools meet the modern manufacturing industry’s demands for precise, efficient, and diversified processing.

Grooving Problems

1. Wear on the back face:

Effect: There is a gradual change in the size of the workpiece or a decrease in the surface finish.

Cause: The linear speed is too high, which has led to the tool reaching its service life.

Measures: To resolve this, adjust your machining parameters. This can include reducing the linear speed or using a more wear-resistant insert.

2. Chipping problem:

Effect: A sudden change in workpiece size or surface finish results in sparking surface burrs.

Reason: The parameter setting is not appropriate, blade material selection is incorrect, workpiece rigidity is poor, and blade clamping is unstable.

Measures: Check whether the parameter setting is reasonable and select the appropriate tool based on the workpiece material.

3. Serious fracture:

Cause: Sudden and unpredictable impact resulting in scrap shank material and defective workpiece.

Reason: The machining parameters are wrongly set and the blade vibration or workpiece blade is not installed correctly.

Solution: Set reasonable processing parameters, reduce the feed, and select appropriate processing blades suitable for chip reduction. Strengthen the rigidity of the workpiece and the blade to prevent future fractures.

4. Accumulated chip tumor.

Impact: The size of the workpiece is inconsistent and the surface finish is poor. Additionally, the workpiece surface has fluff or burrs.

Reason: The chip speed is too low and the feed is not sharp enough.

Measures: To improve the situation, increase the chip speed and use sharper inserts for the feed.

CNC grooving tool safety precautions

Safety precautions for a CNC grooving tool include:

– The operator should operate according to the machine tool operating procedures and observe relevant safety regulations strictly.

– The power supply should be cut off while replacing the tool to ensure safety.

– During use, the tool should be regularly checked for wear and replaced promptly.

– Attention should be paid to protection during operation to avoid workpiece and tool collision.

Application fields of CNC grooving tools

CNC grooving tools are widely used in groove machining work across a variety of fields. For example, in mold manufacturing, they can be used to cut guide grooves. In mechanical manufacturing, they can be used to cut threaded grooves on parts. In electronics manufacturing, they can be used to cut slots in circuit boards, and in metal fabrication, they can be used to cut slots in pipes, among other applications.

Summarize

CNC grooving tools are essential and fundamental in modern-day manufacturing. To fully comprehend their crucial role and advantages in the cutting and machining process, it’s necessary to understand the different types of tools, their functionality, and purpose.
