To give a meticulous smooth finish to the surface, as regards the level, size or finish of the surface of a flat metallic or non-metallic object, surface grinding tools are used. In order to make the surface flat and smooth a spinning wheel that is covered with a rough material is used to grind the plane.
The regular process is surface grinding. It is a finishing procedure. To give an object a superior finish this process is used.
Surface Grinding Machine
Surface grinders consist of a wheel covered with a hard abrasive material, a chuck and a counter table. The non metallic objects are held in place by a vacuum or a mechanical chuck while the wheels grind it and make it smooth. Metal object are held in place by a magnetic chuck.
The crushing wheels of these equipments are covered with different materials like diamond, aluminium oxide, silicon carbide, cubic boron nitride etc. The most commonly used material is aluminium oxide since it is cheaper than other materials.
To maintain the quality of the wheel, grinding dressers are used. For the work to be perfect these wheels must be in perfect condition. Surface grinders are run by hands, electricity or they are powered by hydraulics.
Uses of Surface Grinding Machines
Surface grinders are very important in industries and these are used for making 
parts and industrial tools. It need to be smooth to move and function properly, and here grinding machines play an important role.
These are also used in industries where defined shapes are to be made with precision as in the manufacture of automobile parts. Most of these machines are computer operated, but manual operated machines are also in use.
Cast iron, steel, brass, plastic and aluminium etc. are some of the materials that can be made smooth with surface grinders. During the process of grinding high temperature is created which may weaken the magnetic power in some materials.
Equipments to use while operating Surface Grinders:
While using a surface grinder it is very important to wear safety equipments like goggles. When the wheel spins at a high speed to grind the materials, friction is created and small pieces of material tend to fly away from the wheel which may cause damage to eyes. Protective garments should also be worn like an apron, gloves etc. Loose clothes or items of jewelry should not be worn.
Who can operate a Surface Grinder?
Any person who is qualified and has received sufficient training can operate unit. He must also be trained in health and safety measures to be used while operating the equipment. Health and safety laws must always be followed to prevent any accident.
Conclusion
Therefore, surface grinding machines help to create a smooth finish to the material worked on. It also offers a refined and superior look to the work piece. A right tool for the right task helps to improve the efficiency of the work. This also saves a lot of time and energy for the skilled labours and professionals.
