What is a CNC Gasket Cutting Machine, and How Does It Work?

The CNC gasket cutting machine uses a high-frequency oscillating cutting tool and a computer control system to achieve intelligent cutting. It is designed for precise cutting of non-metallic materials such as rubber, silicone, PTFE and graphite to produce gaskets. It does not require molds and is ideal for customized, low-volume production.

Core Components of a CNC Gasket Cutting Machine

CPU Controller：
The CPU controller receives processing graphics from optimization software and translates them into machine commands. It serves as the brain of the cutting machine, ensuring precise operations.

Cutting System：
Featuring a modular, reinforced tool holder design, the cutting system allows for the configuration of various tools, such as electric oscillating knives, pneumatic oscillating tools, and others. Each tool has distinct applications and benefits, making this system a critical component of the machine.

Vacuum Adsorption System：
Equipped with a 40mm thick aerospace aluminum platform and high-power suction motors, the system includes 8 or 16 zoned adsorption sections. This setup minimizes material movement during cutting, ensuring high-precision results.

Power Drive System：
Both the X and Y axes use servo motors paired with reducers. The X-axis features a dual servo motor drive with ground-grade rack transmission, delivering robust power and precision for cutting operations.

The Role of Oscillating Knives in Gasket Cutting

Oscillating knives are highly effective for cutting materials like rubber, silicone, non-asbestos, cork, and other gasket materials. Their rapid back-and-forth vibrating motion ensures flawless cuts, producing dimensionally accurate gaskets with smooth edges. This precise motion keeps gaskets clean, free from tearing or wear during the cutting process.

Compared to CO₂ Laser Cutting：

  • Oscillating knives excel in cutting non-metallic gasket materials.
  • They cut fire-resistant and high-temperature composite gaskets faster and without emitting toxic gases.

Compared to Milling Tools:

  • For hard PVC gaskets under 5mm, such as PTFE, oscillating knives show clear advantages.
  • Using a 400W high-power electric oscillating tool, they achieve finer cuts with no dust generation and deliver smoother cutting surfaces.
  • Speed, cleanliness, and precision make oscillating knives the preferred choice for high-quality gasket production.
