02. How precise is the cutting, especially for intricate gasket shapes?

Precision is critical in the gasket processing industry, and our CNC oscillating knife cutting machines deliver just that. These machines are engineered to cut gaskets, ensuring that each piece meets stringent specifications accurately.

The cutting precision of our oscillating knife machines is usually within a tolerance of ±0.1 mm, making them ideal for intricate gasket shapes and sizes. This level of accuracy is crucial for creating effective seals in various applications, from automotive to industrial machinery, where even a minor deviation can lead to leaks or system failures.

03. What is the maximum thickness a CNC gasket cutting machine can cut?

In the gasket processing industry, the maximum cutting thickness achievable by a CNC oscillating knife cutting machine can vary, but typically, these machines can handle materials up to 50 mm (about 2 inches) thick. This capability allows for the cutting of a wide range of gasket materials, from thin paper-like materials to thicker, more robust rubber or foam gaskets.

The exact cutting thickness depends on the type of gasket material, please refer to the following table:

04. How fast is the cutting gasket without sacrificing quality?

In the gasket processing industry, the cutting speed of a CNC oscillating knife cutting machine is based on the material type and thickness, but typically, these machines operate at speeds ranging from 50 to 1,000 millimeters per second.

For example, thinner and softer materials like foam or rubber gaskets can be cut at higher speeds, often reaching the upper end of this range. In contrast, thicker or denser materials may require slower speeds to ensure precision and a clean cut without damaging the material.

For the specific cutting speed of a certain type of gasket, you can refer to the table below:

05. Can a CNC gasket cutting machine integrate with existing CAD software?

Yes, CNC oscillating knife cutting machines can indeed integrate with existing CAD (Computer-Aided Design) software, which is a significant advantage in the gasket processing industry. This integration allows engineers and designers to seamlessly transfer their digital designs directly to the cutting machine.

Here’s how it works: The CAD software is used to create detailed designs of the gaskets, specifying shapes, sizes, and cutting paths. These designs are then exported in a format compatible with the cutting machine, often as DXF or PLT files. The machine’s software reads these files and translates the design into precise cutting instructions for the machine to execute.

06. What are the consumables and costs of an oscillating knife cutting machine?

01. Blades: The most frequently replaced consumable. A blade’s lifespan varies based on the material being cut and the intensity of use. The service life is 7-15 days. Regular replacement ensures precision and quality of cuts.

02. Cutting Mats/Underlays: These surfaces protect the blade and ensure clean cuts. The service life is 360-540 days. They wear out over time due to constant contact with the cutting blade and must be replaced to maintain cut quality and machine accuracy.

03. Electricity Consumption: Vacuum pump power consumption: 380V, 7.5KW-9KW; machine power consumption: 220V, 2KW. These machines are generally energy-efficient, but the cost can vary based on usage intensity and local electricity rates.

07. Which cutting tools to choose for gasket cutting?

Selecting the appropriate cutting tool for cutting gaskets with an oscillating knife cutting machine involves understanding the material properties and the specific requirements of the cutting task:

Understanding Gasket Materials
Material Thickness: The thickness of the gasket material is crucial. Thicker materials require blades with greater cutting depths and possibly more robust cutting power.

Material Type: Gaskets can be made from various materials, such as rubber, silicone, fiber, non-asbestosl, or composite materials. Each material has its own cutting requirements, influencing the choice of the blade.

Hardness and Density: Harder or denser materials need blades that are strong and can maintain sharpness, whereas softer materials might require blades with different edge geometries to prevent tearing or distortion.

08. What customization options are available?

When it comes to customizing an oscillating knife cutting machine for cutting gaskets, there are several options you can tailor to meet specific production needs:

Single or Multi-Tool Heads: Choose between a single cutting head for straightforward operations or a multi-tool head that can include different types of blades or tools, such as punching tools or marking pens, allowing for multiple processes in one run.

Table Size: The cutting table size can be customized to accommodate the size of the materials you are working with. The effective working dimensions of the standard CNC gasket cutting machine are: 1600mmX1000mm, 1600mmX2500mm. If you need to meet an oversized spacer cut, a larger format table can be custom-made.

Cutting height: The standard processing height of the machine is 50mm. If you want to meet the needs of cutting thicker materials, the maximum processing height can be customized to 110mm. But one thing worth noting: Please select the feed height according to the actual thickness of the material you are cutting. Do not blindly increase the feed height. This will reduce the machine’s friendliness for thin materials.

09. What maintenance and care is required for an oscillating knife cutting machine?

Maintaining and servicing an oscillating knife cutting machine is crucial for ensuring its longevity, precision, and efficiency:

Blade Maintenance Inspection: Regularly check the blades for dullness or damage. A blunt or damaged blade can affect the quality of the cut and put unnecessary stress on the machine. Replace the blades as needed to ensure optimal cutting performance.

Lubrication Moving Parts: Every 10-15 days, add guide oil to the oil tank of the guide rail slider, and apply butter paste to the rack. Do not use too much grease to cause oil resistance. Regularly lubricate all moving parts, including bearings, rails, and any pivot points.

Mechanical Adjustments: The Y-axis beam is deflected due to external force or sudden power outage. Periodically check and adjust the alignment of the cutting head and the gantry to ensure accurate cuts. Misalignment can lead to imprecise cutting and uneven wear on the machine.

By following these maintenance guidelines, you can ensure that your oscillating knife cutting machine operates efficiently, maintains high precision in cutting, and has a prolonged operational life. Regular and thorough maintenance not only prevents unexpected downtime but also ensures consistent quality in your cutting projects.
