Blade pcb cutting machine

Types of blade PCB cutting machines

Blade PCB cutting machines come with different features and specifications, mainly designed for circuit boards. These have a stable and reliable metal cutting ability and also possess precision control capabilities. According to the working method, the machines are categorized into two types: knife and blade-cutting machines.

Knife cutting machines use a knife to cut the circuit boards accurately without harming the components. They are also known as knife PCBs because they use a digital control system that allows precise and clean cuts. Additionally, these machines are quiet with minimal noise levels and can also be used to cut different materials, including ACRYLIC, ALUMINUM, COMPACT LAMINATED, POLYCARBONATE, PVC, etc. Customization is possible when it comes to these machines, as they can be tailored according to specifications and requirements, whether for size or any other feature.

BLADE PCB cutting machines work differently from knife-cutting machines. They utilize a rotary blade to cut printed circuit boards. The blade is pushed upward to provide a smooth and burr-free edge on both sides. In addition to this, the blade offers fast cutting speeds and a long service life. Like knife cutting machines, they can cut other materials besides the PCB. A blade cutting machine has many applications in the electronic industry, especially during the final assembly stage when several small PCBs need to be cut from a larger one. Using a blade PCB cutting machine ensures a faster production rate with high accuracy.

When looking for a PCB cutting blade, one must ensure it is of high quality. The product's design and the component's performance will usually depend on the PCB cutting blades that have been used.

Apart from knife and blade cutting machines, other types include:

• Laser cutting machines:

  Using high-powered lasers to cut circuit boards, laser cutting machines provide a high-precision cutting method. Incredibly delicate cuts are achievable without compromising the board's integrity. Because of their non-contact nature, laser cutters don't cause any physical pressure to the material.

• Flame cutting machines:

  Flame cutting machines use a metal cutting torch to cut the device. Usually, they are manufactured by OEM providers. These machines are ideal for cutting thicker materials. Additionally, they're adopted by the hybrid manufacturing approach to significantly improve the speed and flexibility of device creation.

• Water jet cutting machines:

  Water jet cutting machines employ a high-pressure water stream to manipulate the material precisely. They possess the capability to cut phsically sensitive materials without causing environmental hazards.

• Router cutting machines:

  These are the most common types of machines used when manufacturing PCBs. Generally, a router machine employs a rotating bit to extract material from a board, thereby creating a desired pattern or shape. The accuracy level of such machines is quite high. These are often used with special tools.

Specification and maintenance of blade PCB cutting machines

Specification

The following specifications apply to the blade PCB cutter;

• Operating voltage: 220V is the standard value for blade PCB cutters. However, some machines can operate at a voltage of 100-240V.
• Cutting speed:The cutting speed varies depending on the machine model, but it is usually between 3,000 and 42000rpm.Sometimes, laser cutting machines have higher speeds than blade cutters.
• The power of the motor: The motor power is between 60W and 1,500W, and this power turns the blades at cutting speeds.
• The weight of the machine: Depending on the model, the weight of a blade PCB cutting machine can range from 2.5 to 8.5kg.
• Blade diameter: The diameter of the blade used in this machine is usually between 0.6mm and 2.0mm.
• Cutting Thickness: The maximum thickness that a blade cutting machine can process is 3mm (including the thickness of the circuit board and the blade).

Maintenance

• Regular cleaning:Cleaning the machine can keep it in great condition. Keep the work surface, cutting area, air intake ports, and exterior free of any residue or dust, using a soft brush or air pump.
• Using Proper Lubrication: Lubricate moving parts such as slide rails and bearings. Apply a very small amount of lubricant to minimize dust accumulation and ensure smooth operation.
• Periodic Blade Replacement: Replace the blade if it becomes blunt or damaged to maintain cutting accuracy and efficiency. Ensure the replacement blade is compatible with the machine model. The cutting performance can be improved and the machine's lifespan extended by accurately aligning and securely attaching the new blade.
• Adjustment and calibration: Regularly check and calibrate the machine's parameters, ensuring the blade's height, cutting pressure, and speed are appropriately adjusted. These measures improve cutting quality, reduce uneven or excessive cuts, and limit the damage to the circuit boards and the blade.
• Avoid overloading: It is better to cut fewer pieces rather than more, as overloading one's work can be detrimental. Set a reasonable production target and take breaks to allow the machine to cool down. This approach prevents overheating, motor damage, and premature blade wear from excessive driving.
• Dust control:Provide effective dust extraction or suction during cutting to keep the work area tidy and limit the accumulation of printed circuit board residues on the machine. This practice reduces the risk of circuit board cutting edges becoming blunt, affecting the machine's cutting performance and precision.
• Environmental requirements: To avoid damage to the machine and printed circuit boards, it is important to avoid harsh environments such as high humidity, high temperatures, and flammability. Protect the machine from moisture, bacteria, corrosive substances, excessive heat, and fires, and ensure that the air circulation at the installation site is good. The equipment remains in a stable operating state, and the electronic components and circuit boards won't be degraded or spoiled prematurely.
• Using Proper Tools: When replacing the blade or other machine parts, use the recommended tools. This practice helps avoid damage to the equipment or its components and ensures proper fit and performance.

Applications of PCB cutting machines

PCB cutting machines have a wide range of applications in various industries. Here are some of them:
