Introduction
In Digital Cutting Production, choosing the right Cutting Tools is as important as choosing a Cutting Machine. There are differences in the Thickness, Density and Flexibility of different materials. If the inappropriate Cutting Tool is used, it may lead to a decrease in Cutting Quality, an increase in Material Waste, or even shorten the Blade Service Life.
For Packaging Manufacturers and Industrial Cutting Businesses, understanding the functions of different Digital Cutting Machine Tools can help you improve Cutting Accuracy and Production Efficiency.
This article will introduce the main features of Oscillating Knife, Pneumatic Knife, Drag Knife, Creasing Tool and V-Cutting Tool, and help you choose the right Cutting Tools according to different materials.
What Are Digital Cutting Machine Tools?
Digital Cutting Machine Tools are tools installed on Digital Cutting Machine to complete Cutting, Creasing, V-Cutting and other processing operations.
These tools are usually controlled by the CNC Control System to complete the processing according to Digital Design Files and preset Cutting Parameters.
Different Cutting Tools have different ways of working. For example, Oscillating Knife cuts materials through Blade Oscillation, while Drag Knife mainly relies on the relative movement between Blade and the material to complete cutting.
Common Digital Cutting Machine Tools include:
- Oscillating Knife: Suitable for cutting a variety of flexible materials and some thicker materials.
- Pneumatic Knife: Use Pneumatic Drive to achieve Blade Oscillation, which is suitable for some high-resistance materials.
- Drag Knife: often used for thinner flexible materials.
- Creasing Tool: Used to form Fold Lines on Cardboard.
- V-Cutting Tool: Used to make V-Shaped Grooves to help materials achieve folding at a specific angle.
For factories that need to process a variety of materials, suitable Tool Configuration can improve the flexibility of equipment and reduce additional equipment investment.
Why Does Cutting Tool Selection Matter?
Cutting Tool Selection directly affects Cutting Accuracy, Production Speed, Material Waste and Operating Costs.
Improved Cutting Quality
Different materials require different Cutting Methods. For example, thicker Foam Materials may require Oscillating Knife, while thinner Flexible Materials may be more suitable for Drag Knife.
Choosing the right Cutting Tool can help get more flat Cutting Edges and more stable Cutting Results.
Higher Production Efficiency
If the Cutting Tool does not match the material, Operators may need to reduce the Cutting Speed or increase the Cutting Passes.
Appropriate Tool Configuration can reduce unnecessary processing steps and improve Production Efficiency.
Reduced Material Waste
Incorrect Cutting Tool may cause Material Tearing, Uneven Edges or Incomplete Cutting.
Defective Products and Material Waste can be reduced by selecting Cutting Tools suitable for materials.
Lower Maintenance Costs
Using inappropriate Blade may speed up Blade Wear and increase Replacement Frequency and Maintenance Costs.
Therefore, when choosing Cutting Tools, you should not only consider Initial Cost, but also evaluate long-term Operating Expenses.
Main Types of Digital Cutting Tools
There are differences in the working principles and applicable materials of different Digital Cutting Tools. Understanding these features can help you choose the tools that suit your production needs.
Oscillating Knife
Oscillating Knife is a common Cutting Tool in Digital Cutting Machine, which uses the high-speed reciprocating movement of Blade to cut materials.
Compared with ordinary Drag Knife, Oscillating Knife can get better Cutting Performance for some thicker or resistant materials.
Common applications include:
- Corrugated Cardboard
- Foam materials
- Rubber sheets
- Leather
- Partially flexible Composite Materials
The Cutting Performance of Oscillating Knife depends on Blade Type, Oscillation Frequency, Cutting Speed and Material Thickness.
For manufacturers who need to process different Packaging Materials, Oscillating Knife is one of the tools worth considering.
Pneumatic knife
Pneumatic Knife usually uses Compressed Air to drive Blade for back and forth movement.
Some Pneumatic Oscillating Knife has a large Cutting Stroke, which is suitable for processing some thicker or cutting resistance materials.
Common applications include:
- Thick Corrugated Cardboard
- Honeycomb Board
- Dense foam materials
- Some Industrial Cushioning Materials
When using Pneumatic Knife, you need to confirm Air Supply Requirements, Blade Length and Maximum Cutting Thickness.
Not all Pneumatic Knifes are suitable for the same material, so it is recommended to verify the actual processing effect through Sample Cutting
Drag knife
Drag Knife is a relatively simple Cutting Tool, which mainly completes cutting by moving the Blade on the surface of the material.
During the processing process, Blade usually automatically adjusts the direction according to the Cutting Direction.
Drag Knife is often used for:
- Thin paper
- Vinyl
- Thin Plastic Films
- Adhesive materials
- Some Thin Flexible Sheets
Drag Knife is usually suitable for materials with low Cutting Resistance.
For thicker or harder materials, the use of Drag Knife may cause a decrease in Blade Deflection or Cutting Quality.
Therefore, when choosing a Drag Knife, you should focus on Material Thickness, Blade Angle and Cutting Speed.
Creasing Tool
Creasing Tool is mainly used to form Crease Lines on Cardboard and other foldable materials, rather than cutting materials completely.
In Packaging Production, Creasing Tool can help manufacturers make Folding Boxes, Cartons and Custom Packaging Structures.
Common applications include:
- Folding cartons
- Corrugated Packaging Boxes
- Display packaging
- Custom Cardboard Structures
When choosing Creasing Tool, you need to consider Material Thickness, Flute Direction and Creasing Pressure.
If the Creeasing Pressure is too high, it may damage the surface of the material; if the pressure is insufficient, it may lead to the instability of Folding Quality.
For Packaging Manufacturers who need both Cutting and Creasing, Digital Cutting Machine, which supports a variety of Tool Functions, can reduce additional processing steps.
V-cutting tool
V-Cutting Tool is used to form V-Shaped Grooves on the surface of the material, so that the material can be folded at a specific angle.
Unlike ordinary Straight Cutting, V-Cutting usually removes part of the material while retaining the material layer that needs to be connected.
Common applications include:
- Honeycomb Board Packaging
- Thick Cardboard Structures
- Protective Packaging Components
- Custom Display Structures
V-Cutting Tool is especially suitable for some Packaging Designs that require Angle Folding.
When selecting V-Cutting Tool, you should confirm the Cutting Angle, Material Thickness and Groove Depth.
If the V-Cutting Depth setting is incorrect, it may cause the material to fail to fold properly or destroy the connection layer that needs to be retained.
How to Choose Cutting Tools for Different Materials
When choosing Digital Cutting Machine Tools, you first need to understand the Physical Properties of the material, including Thickness, Density, Hardness and Flexibility.
Different materials may require different Cutting Methods, so it is not recommended to choose tools based on Cutting Speed alone.
Corrugated Cardboard
Corrugated Cardboard is widely used in Packaging Boxes, Protective Packaging and Shipping Cartons.
Because the material has a Fluted Structure inside, it is necessary to avoid excessive squeezing when cutting to prevent Corrugated Flutes from deforming.
For Corrugated Cardboard, common Tool Options include:
- Oscillating Knife: Used to cut Cardboard Shapes.
- Pneumatic Knife: It can be used for some thicker Corrugated Cardboards according to the material thickness and equipment configuration.
- Creasing Tool: Used to form Fold Lines.
If your factory mainly produces Custom Packaging Boxes, it is recommended to choose Tool Configuration that can complete Cutting and Creasing.
This can reduce the additional processing steps and improve the Packaging Production Efficiency.
Honeycomb Board
Honeycomb Board has a thick internal structure and is often used for Protective Packaging and Industrial Packaging.
Compared with ordinary Corrugated Cardboard, some Honeycomb Boards require greater Cutting Depth.
When processing Honeycomb Board, you can consider Pneumatic Knife or suitable Oscillating Knife according to the material thickness and structure.
If Packaging Design needs Angle Folding, V-Cutting Tool can also be evaluated.
When choosing tools, you should focus on checking:
- Maximum Cutting Depth
- Blade length
- Material Compression
- Cutting Edge Quality
For thicker Honeycomb Board, it is recommended to perform Sample Cutting first to confirm whether the tool can complete the required Cutting Paths.
Foam materials
Foam Materials include EPE Foam, EVA Foam, PU Foam and other Industrial Foam.
There are obvious differences in Density, Elasticity and Thickness of these materials.
Oscillating Knife can be used in some Foam Cutting Applications, but the specific Tool Selection needs to be determined according to the material characteristics.
For example, softer Foam Materials may have Compression during cutting, while Foam with higher Density may require different Blade Configuration.
When choosing Foam Cutting Tools, you should focus on Cutting Depth, Blade Sharpness and Material Fixation.
For Custom Foam Packaging, stable Cutting Accuracy can help you produce Protective Inserts of consistent size.
Fabric and Leather
Fabric and Leather are widely used in Automotive Interiors, Furniture Manufacturing and Fashion Products.
These materials usually have high Flexibility and are easily affected by Material Movement during the cutting process.
For Fabric Cutting, Oscillating Knife or other special Cutting Tools can be considered according to the material type.
For Leather Cutting, you need to choose the appropriate Blade according to Leather Thickness, Surface Properties and Cutting Requirements.
When processing these materials, in addition to Tool Selection, you also need to pay attention to Material Fixation and Cutting Path Optimization.
Appropriate Vacuum System or other Material Holding Methods can help reduce material movement and improve Cutting Accuracy.
Composite materials
Composite Materials is usually a combination of two or more materials, and its Cutting Requirements depend on the specific Material Structure.
Some flexible Composite Sheets can be processed using appropriate Digital Knife Cutting Tools.
However, for Glass Fiber Reinforced Composites, Carbon Fiber Reinforced Composites or other high-hardness materials, ordinary Oscillating Knife is not necessarily suitable.
When selecting Cutting Tools, you need to confirm:
- Material composition
- Material thickness
- Cutting Resistance
- Blade Wear
- Required Edge Quality
For special Composite Materials, Supplier shall be required to provide Material Compatibility Information and Sample Cutting Results.

Using the wrong Blade may lead to Uneven Cutting Edges, Incomplete Cutting or Blade Damage.
Therefore, the appropriate Blade Type should be selected according to the Material Properties and refer to the suggestions of the Equipment Supplier.
Ignoring Material Thickness
Material Thickness affects Cutting Depth and Blade Selection.
If the Blade Length is insufficient, it may not be possible to completely cut the material.
For Thick Cardboard or Foam Materials, Cutting Resistance and Material Compression also need to be considered.
Before purchasing Cutting Tools, you should confirm the Maximum Cutting Thickness and check the actual effect through Sample Cutting.
Incorrect Cutting Parameters
Cutting Parameters include Cutting Speed, Cutting Pressure, Blade Depth and other settings related to Tool Configuration.
If the Cutting Speed is too fast, Cutting Errors may occur; if the Cutting Pressure is inappropriate, it may cause Material Damage.
It is recommended to establish standardized Cutting Parameter Settings according to different materials.
By recording verified parameters, you can reduce the repeated debugging time and improve Production Consistency.
Neglecting Tool Maintenance
Cutting Tools will gradually wear out during long-term use.
If the Blade Condition and Tool Holder are not checked regularly, it may lead to a decrease in Cutting Quality.
It is recommended to establish a Preventive Maintenance Schedule and focus on checking:
- Blade sharpness
