Introduction Abrasive grinding and polishing machines are used in various industries for material removal, finishing, and surface preparation. These machines are equipped with abrasives, which are materials used for grinding, cutting, and polishing. Abrasives are available in different compositions and forms, including bonded, coated, and loose abrasives. Understanding the use of content and composition of abrasives, as well as safety precautions, is essential for achieving optimal results and ensuring worker safety. Use of Abrasives Abrasives are used in grinding and polishing machines to remove material from a surface and achieve a smooth finish. The choice of abrasive depends on the material being worked on, the desired finish, and the operating conditions of the machine. Abrasives are available in different shapes and sizes, including wheels, belts, discs, and brushes. The shape of the abrasive depends on the surface area being worked on and the type of machine being used. Composition of Abrasives Abrasives are composed of abrasive grains, bond material, and filler material. The abrasive grains are the actual cutting materials and are available in different types, including diamond, silicon carbide, aluminum oxide, and cubic boron nitride. The bond material holds the abrasive grains together and provides strength and rigidity. The bond material is available in different types, including resin, vitrified, and metal. The filler material is added to the abrasive mixture to increase the bulk density and prevent voids. Safety Precautions Working with abrasive grinding and polishing machines can be hazardous if proper safety precautions are not taken. Some of the safety precautions that should be followed include: Use Personal Protective Equipment (PPE): Workers should wear appropriate PPE, including safety glasses, gloves, and respirators, to protect themselves from flying debris and dust. Machine Inspection: The machine should be inspected before use to ensure that all guards, shields, and safety devices are in place and functioning correctly. Abrasive Selection: The appropriate abrasive should be selected for the material being worked on, and the machine should be operated within the abrasive's recommended operating range. Machine Operation: The machine should be operated according to the manufacturer's instructions and with caution. Machine Maintenance: The machine should be properly maintained to ensure that it is in good working condition and safe to use. Conclusion Abrasive grinding and polishing machines are essential tools in various industries for material removal, finishing, and surface preparation. Understanding the use of content and composition of abrasives, as well as safety precautions, is crucial for achieving optimal results and ensuring worker safety. It is essential to select the appropriate abrasive for the material being worked on and operate the machine with caution while wearing appropriate PPE. By following these guidelines...

How to improve the grinding efficiency of vibration Last time, we have introduced the advantages of vibration. Now, let’s say something about how to improve the grinding efficiency of vibration. Firstly, choose the right polishing media is very important. For different products, it need to match with different media, even in different process. Such as for resin craftwork, we use resin media for the rough step and alumina porcelain or high frequency porcelain. But for metal parts, we use corundum spheres for the rough step and alumina porcelain for fine step. For different media, it has different cutting force, which can help to achieve the different effect Secondly, it’s about the brightening agent. Not matter rough step or fine step, we advise to add the brightening agent to help the media to display the biggest effect. Also the agent contains some ingredients which can protect the surface of workpiece. Thirdly, for different workpieces, we can choose different machine with suitable size to match. That will save polishing media and reduce working time and improve the grinding efficiency.

The advantages of vibration As we got lots of inquiries about the vibrating grinder. In fact, vibration as traditional polishing machine widely used in different industries. Such as Eyewear, arts and crafts, sanitary, medical and so on. The main purpose is to remove the burrs, polish and clean the rusted surfaces. Here, we would like to have a brief introduction for the advantage of vibration: 1.It suitable for lots of different material. Take Eyewear as an example, the injection frame can be polished in this machine, the metal temples also can be polished. Just change the media and process. 2. Easy to operate: Just put the workpiece and media inside the container, setting the data and turn on the start button, the whole polishing process can be finished by itself. 3. As the we have many different size and shape of vibration grinder, the producer can have different choices for different products. Take auto motor as an example, for the hub, we can use the round machine with 600L capacity. If for exhaust pipe, we can choose the 2400*800cm square machine.

Grinding equipment--Wet grinder The polishers have wet grinder and dry grinder. For all the polishers, can clean, smooth and refine items with basically no labor on your part. Today, we’re going to introduce wet grinders to you: For metal products. We can use wet grinder as following machine: This machine is specialized in surface treatment for metal products. There are 8 racks inside the barrel. All the products can be put on the rack one by one to avoid the scratches. We will design different rack to match different products. PLC controller (For export, all the information will update to English version) Frequency controller which make sure the speech should be match the different products. Operation plate. Please click the link for more details: We want to take metal eyewear temples as example for machine testing. Please contact us for more process details.

Surface finished of Medical clam(Stainless steel) Last time, we introduced the wet polishing of electrical heated tube in magnetic machine. Today, we will introduce the dry polishing of another product--Medical clam(stainless steel) Firstly, we should know about the polishing media. For dry polishing, we also have lots of different polishing abrasives. Such as walnut shell, beech wood, corncob and so on. For sure, different polishing steps should match different size media and different polish compound. Secondly, let me introduce our polishing machine we use for the medical clam. Here is our dry polishing machines for metal products. It has enough space for 480 pieces products(Size reference：30*15*10CM). It has different rack inside the barrel and the rack custom-made for different products. Here we take Medical clam(Stainless steel)as example: Original piece,rough and dirty... After rough polishing and fine polishing, the surface finished will be like: For more details, welcome to contact us for polishing process.

Save Time, Grit, Polish and Electricity Compare to traditional polishing machine- vibration, our tumbling machine for injection can help the producers to save time and money. Here we have a comparison for your reference: Now, let’s introduce this machine by details: Firstly, the appearance of machine base on the design in year 2018, we made more improved in size, safety protection and operation ease. Secondly, it about the reduce the noise. For vibration, one machine will cause higher than 95 db, when it works. And if more 6 sets machines working together, the decibel will be higher than 130 db, which are very harmful for the operators, But for the tumbling machine, one machine will cause lower than 60 db, and it won’t higher than 85 db, even 18 sets machine working together. Thirdly, this machine controlled by PLC, which make sure the polishing time are same in positive and negative rotation. The surface finished will be more stable. Fourth, the automatic water inlet and outlet system, improve the surface clearness of products, which will be better for painting step, save the paint and increase the spray paint quality. Here we take injection sunglasses as reference: This polishing machine effective for inner groove & model line,saving paint due to the smooth surface finished. There are only 2 step for the whole polishing process: 1.5 hrs for rough polishing and 0.5 hrs for fine polishing. According to all the data, we recommend this tumbling machine for injection products.
