Top Double-Sided Tapes for CNC Machining:A Comprehensive Guide

As CNC machining becomes increasingly popular among various industries,choosing the right tools and accessories can significantly impact work efficiency and the quality of finished products. One of the most critical yet often overlooked aspects of a successful CNC machining operation is selecting the proper adhesive or tape to hold workpieces securely.

Double-sided tape has been a go-to choice for many in the CNC machining industry. It provides a strong bond,easy application,clean removal,and minimizes the potential for workpiece damage. This blog post will explore the best double-sided tapes for CNC machining and provide insights to help you make the right selection for your specific needs.

What to Consider When Choosing Double-Sided Tape for CNC Machining

Before we dive into the top double-sided tapes,let–s examine the factors that play a crucial role in determining the best adhesive option.

1. Adhesion Strength:Depending on the type of material being machined,the tape should be strong and durable enough to hold the workpiece securely against the cutting forces generated during machining processes.

2. Temperature Resistance:CNC machining generates heat,and a tape with good temperature resistance will ensure that it remains effective despite the heat produced during milling,cutting or drilling operations.

3. Ease of Removal:The tape should ideally leave no residue when removed,especially if the final product requires a clean,smooth finish. The tape should also offer clean release properties,allowing for easy and damage-free removal of the workpiece.

4. Thickness:The tape–s thickness should be taken into consideration,as it may affect cutting depth and workpiece height. A thinner tape offers better contact between the workpiece and the machine bed,while a thicker tape provides more cushioning if needed.

With these factors in mind,let's explore some of the best double-sided tapes available in the market for CNC machining applications.

3M VHB Tapes

3M's VHB (Very High Bond) tapes offer superior strength and long-lasting adhesion,making them a popular choice for CNC machining projects. These tapes have a closed-cell acrylic foam construction that provides excellent resistance to heat,chemicals,and UV exposure. The VHB series also boasts an unmatched bonding performance on various materials,including metal,glass,and plastic.

Popular options within the VHB series include:

1. 3M VHB 4941F Tape:This tape features a conformable foam carrier that adheres well to most surfaces,providing a strong bond for high-stress applications.

2. 3M VHB 4622 Tape:Suitable for applications involving elevated temperatures,this tape withstands heat up to 300–F and offers excellent adhesion to medium and high surface energy substrates.

3. 3M VHB RP62 Tape:This general-purpose tape offers long-lasting adhesion and is ideal for applications requiring dynamic stress or surface vibration.

Scotch Double-Sided Tapes

Scotch–s range of double-sided tapes offers excellent adhesion and a clean removal for various CNC machining applications. The tape's unique construction minimizes residue left behind,making it a favorite among CNC professionals.

1. Scotch 665 Double-Sided Tape:With a strong adhesive on both sides and a film carrier,this tape is excellent for holding a workpiece securely during machining. The tape is easy to apply and can be torn by hand for quick application.

2. Scotch Permanent Outdoor Mounting Tape:This weather-resistant tape is designed for outdoor applications and offers a high bond strength,making it suitable for CNC machining of heavier workpieces.

Tesa Double-Sided Tapes

Tesa is a renowned manufacturer of high-quality adhesive tapes,and their double-sided tapes have found a place in many CNC workshops worldwide. These tapes offer a reliable bond,clean removal,and good temperature resistance.

1. Tesa 4965 Double-Sided Tape:With a PET film carrier and strong acrylic adhesive,this tape is ideal for high-tension applications and mounting heavier workpieces on CNC machines.

2. Tesa 62932 Double-Sided Tape:This tape–s soft and flexible PE foam carrier ensures excellent conformity to various surfaces. It is also resistant to water,solvent,and aging.

Nitto Double-Sided Tapes

Nitto–s double-sided tapes provide secure bonding for an array of CNC machining applications. The tapes are designed to withstand machining pressures and offer clean removal upon completion.

1. Nitto 5000NS Double-Sided Tape:This tape has a non-woven fabric carrier,ensuring optimal bonding and easy handling during application ensuring the security of your workpiece.

Each of these double-sided tapes stands out as an excellent choice for CNC machining,but the best tape for your specific application will ultimately depend on the particular requirements of your materials,machine,and desired outcome. Don't be afraid to experiment with various tapes until you find the one that suits your needs best. The right tape can make all the difference in the quality of your finished product and the efficiency of your machining process.
