Applications
CNC Vacuum Suction Table Auxiliary Film can be used as a temporary fixation and auxiliary positioning material for processing applications where improved workpiece stability is required.
Typical applications include:
- CNC vacuum suction tables
- CNC engraving
- CNC cutting
- Precision cutting
- Temporary workpiece fixation
- Small workpiece positioning
- Plastic and sheet material processing
- Precision machining assistance
- Vacuum workholding
- Other applications requiring temporary auxiliary fixation
Actual suitability should be evaluated according to the workpiece material, machining process, vacuum pressure, temperature, and other operating conditions.
Working Principle
CNC vacuum suction tables normally use vacuum pressure to hold a workpiece against the table surface.
For some small, lightweight, or difficult-to-position workpieces, vacuum suction alone may not provide sufficient fixation. In such cases, an auxiliary adhesive film can provide additional temporary adhesion.
The adhesive film can be applied between the workpiece and the relevant contact surface to provide auxiliary fixation during processing.
Typical Application Process
1. Surface Cleaning
Clean the contact surfaces to remove dust, oil, moisture, and other contaminants.
2. Film Application
Apply the adhesive film evenly to the required area and avoid wrinkles and trapped air.
3. Workpiece Placement
Place the workpiece onto the adhesive surface and apply suitable pressure to ensure sufficient contact.
4. Vacuum Fixation
Activate the vacuum system and confirm that the workpiece is securely positioned.
5. Processing
Carry out CNC machining, engraving, cutting, or other processing according to the actual application.
6. Removal
After processing, remove the workpiece and adhesive film using a suitable peeling method according to the application conditions.
Specific application parameters should be tested and adjusted according to the actual workpiece and processing conditions.
Thickness Selection
The product is available in a 0.04–0.24 mm thickness range.
The appropriate thickness should be selected according to the workpiece, application method, processing conditions, and required adhesion performance.
Customizable Width
CNC Vacuum Suction Table Auxiliary Film supports customizable widths and can be matched to different CNC equipment dimensions and application requirements.
Customers can provide the following information for specification evaluation:
- Required width
- Required roll length
- Film thickness
- Actual application conditions
- Estimated purchase quantity

FAQ: How to Choose a High-Temperature Film for CNC Machining?
1. What type of high-temperature film is suitable for CNC machining?
The right film depends on the machining process, operating temperature, workpiece material, and application requirements. PET film with silicone adhesive may be suitable for temporary workpiece fixation on CNC vacuum tables, while polyimide (PI) film is commonly considered for high-temperature masking and electrical insulation applications.
2. Can PET silicone adhesive film be used for CNC vacuum suction tables?
Yes. PET silicone adhesive film can serve as an auxiliary fixation and positioning material for CNC vacuum suction table applications. Its suitability depends on the workpiece surface, vacuum pressure, machining conditions, and required holding force.
3. What temperature can CNC vacuum suction table auxiliary film withstand?
The specified CNC vacuum suction table auxiliary film has a long-term temperature resistance of 0°C to 180°C and a short-term temperature resistance of up to 220°C. Actual performance should be evaluated under the intended operating conditions.
4. Should I choose PET film or polyimide film for CNC machining?
PET silicone adhesive film may be suitable for temporary workpiece fixation and auxiliary positioning. Polyimide film may be more appropriate for certain high-temperature masking and insulation applications. Selection should be based on actual temperature exposure, adhesive compatibility, and the required performance.
5. How can I prevent adhesive residue after CNC machining?
Choose a film with adhesive properties compatible with the workpiece material and test its removal performance under actual machining conditions. Surface cleanliness, application time, temperature, and contact pressure can affect residue. Clean removal should be confirmed through testing rather than assumed.
6. Is the CNC auxiliary film available in custom thicknesses and widths?
Yes. The film thickness range specified for this product is 0.04–0.24 mm, and the width can be customized according to customer requirements. Roll length and other specifications can also be discussed based on the application.
7. What information is needed to select the right CNC machining film?
To recommend a suitable film, provide the workpiece material, machining method, operating temperature, required holding force, film dimensions, exposure to cutting fluids or oils, and removal requirements. These details help determine whether the product is suitable for the intended application.
