Auto Charging Solar Grinding Machine Report Free Download


The Machine we designed and fabricated is used for grinding any shape of object like Circular, Rectangular, and Polygon. In our project grinding machine is used to grinding the different types of material. The grinding machine is rotated by the single phase induction motor. Hence our project namely solar powered auto charging grinding machine is a Special type of Machine. According to the type of material to be grind, the grinding tool can be changed.
This project gives details of grinding various shapes and sizes of components. This machine can be widely applied in almost all type of industries. By varying the pulley sizes I can get a high end speed of over 10,000 rpm if needed. The only change I would make is to have a totally enclosed motor to keep out the grit.


Our project is design and fabrication of auto charging grinding machine. It is used to grind the machining surfaces to super Finish and accuracy. The principle parts of this attachment are main body, motor with pulley, bearings, rope pulley and alternator etc. Manufacturing is derived from the Latin word manufactures, means made by hand. In modern involves making products from raw material by using various processes, by making use of hand tools, machinery or even computers. It is therefore a study of the processes required to make parts and to assemble them in machines.The study of manufacturing reveals those parameters which can be most efficiently being influenced to increase production and raise its accuracy.
Grinding is a metal removal process that employs an abrasive GW whose cutting elements are grains of abrasive materials of high hardness and high refractoriness The sharp-edged and hard grains are held together by bonding material. Projecting grains (Figure 1) abrade layers of metal from the work in the form of very minute chips as the
wheel rotes at high speeds of up to 60 m/s.

Working Principle

This concept contains simple arrangements. It consists of grinding wheel, solar panel, battery, motor etc. The grinding wheel is fixed on a motor shaft. The battery, solar panel and grinding wheel arrangements are mounted on assembly box. The solar panel generates the power supply from direct sunlight. Then the generated energy is stored in the batteries. The store energy in the battery is used to run the motor. The grinding wheels are fixed at the motor shaft. The motor shaft rotates the grinding wheel. A handle is placed with spring arrangement to move the grinding wheel up and down. In idle time the motor is switch off by the manual process.


  • Cheapest method
  • Usage of solar energy
  • Low power consumption
  • Available source


  • Solar energy is only available in day time.


  • Used small scale industries
  • Pattern shops
  • Lathe workshops for make surface finish in specimens


The solar grinding machine is designed, fabricated and tested. This machine does not employees any use of power equipments such as DC motors and it is fully human operated . The use of this machine makes the grinding process faster hence reduce most of the time and labour required to operate the machine is also less. This machine is helpful for small as well as big firms. This human powered machine will help to improve an economical condition. This is new type of machine which is different to the other grinding machine which are used for grinding purpose till now.
