Extrusion Grinding
Extrusion grinding is a process utilized in manufacturing to refine raw materials into a high-precision, fully finished product. It is important to use the correct methods, materials and finishes in order to get the best performance out of the finished product. In extrusion grinding, metal is melted, heated and forced through a die. This forms the metal into a desired shape that is then ground on a vertical spindle grinding machine for a superior finish, with the result being that the end product can achieve high-precision tolerances, smooth surfaces and tight tolerances of complex geometries.
The process of extrusion grinding starts with a high-temperature metal alloy being directed into a closed die. The closed die and heated metal alloy are then forced through it by a plunger, which creates pressure that smoothes and shapes the metal into the desired shape. This is known as the extrusion process, which creates a specific shape. This process can also be used to create parts with large aspect ratios, such as bars and rods.
Once the metal extrusion has been created, it will have to be ground to a high-precision finish. To do this, it is placed on a vertical spindle grinding machine, which is designed to hold the object while it is being worked. A specialized grinding wheel is then used to cut away small amounts of material in order to achieve a uniform and perfectly smooth surface. Extrusion grinding can be used on all types of metals, including hard metals such as stainless steel and aluminum, as well as softer metals like brass and copper. The process is fast and efficient, producing parts that are very accurate and consistent.
Due to the nature of the pressure used in the process, parts that go through extrusion grinding can also withstand extreme pressure and heat. This makes extrusion grinding an ideal choice for parts that require a long-term, durable finish. Extrusion grinding does not produce any dust or fumes, as the process creates a contained, sealed environment. Additionally, because the process does not involve any harsh chemicals or coolants, it is one of the few green approaches to precision grinding.
In summary, extrusion grinding is a highly specialized process that can produce parts with superior finishes and tight tolerances. It is fast, efficient and eco-friendly, making it an ideal choice for those who need parts with complex geometries that can withstand extreme pressures and temperatures. The process can be used on a wide range of metals, including hard metals such as stainless steel and aluminum, as well as softer metals like brass and copper.
