A brief introduction to the knowledge of suction nozzles for surface mount technology (SMT) machines

The materials of the suction nozzles of surface mount technology (SMT) machines are generally divided into three types, namely tungsten steel, ceramic, diamond steel or black material. Now let's introduce the advantages and disadvantages of the above three materials to you.

Common SMT nozzles can be roughly classified by the materials used in production and processing as follows: alloy materials; Fiber material; Molded material; Ceramic materials. Nowadays, the best ones are ceramic suction nozzles and even those made of diamond steel. This material is not only wear-resistant but also solves the problem of the tip turning white and affecting the usage effect, thus having a longer service life. The following lists the advantages and disadvantages of several commonly used materials for your reference.

• Features of tungsten steel suction nozzles:
  Advantages: low cost and not prone to breakage. The drawback is that it tends to turn white.
• Ceramic head suction nozzle:
  Its advantages are that it never turns white and is not expensive. The disadvantages are that it is prone to breakage and a small piece will fall off if accidentally touched.
• Diamond steel suction nozzle:
  Its advantages are that it never turns white and is not prone to cracking. The disadvantage is that it is expensive.

Surface mount technology (SMT) machine suction nozzle

The surface mount technology (SMT) machine nozzle, also known as the nozzle or suction nozzle, is an accessory used on SMT machines. So, how is the SMT machine nozzle processed?

Before I came into contact with the product of the surface mount technology (SMT) machine nozzle, I thought making a nozzle was a very simple thing. First, it was very small, so it felt very simple. Second, there was nothing particularly special about its appearance. However, after a week of learning in the SMT machine nozzle factory, I found that processing a small nozzle is not an easy task.

First, let's talk about the composition structure of the suction nozzle. This suction nozzle is generally composed of a base and a nozzle head. The base is usually processed from steel, and there are several types of materials for the nozzle head, including ordinary steel, tungsten steel, ceramic, and diamond steel. Diamond steel is also called black material. Although it seems very simple that a suction nozzle is made up of two parts However, even the most common suction nozzle has ten processes, including material cutting, turning the shape on a CNC lathe, rounding, drilling, assembling the nozzle head, rough grinding (flat grinding, cylindrical grinding), fine grinding, cutting the inner hole, polishing, inspection, etc. Each process requires specially customized tooling fixtures, and a full inspection is needed at each process, mainly checking various dimensions and appearances. This can also well guarantee the quality of the products. It is precisely for this reason that our products have received unanimous recognition in the industry.
