Design of a Multipurpose Polishing Machine for Domestic Applications

The design of a multipurpose polishing machine for domestic use was selected as the subject of this thesis in answer to an existing demand for such a device. A study was made of the potential market, the consumer requirements and the competitive machines. A functional analysis of the proposed machine in conjunction with consideration of the possible methods of manufacture established the general form of the unit. Further refinement of the design from the standpoint of engineering and appearance defined the final form. The proposed machine is composed of a universal series motor with geared drive to the disc or polishing head. Integral handles make the device suitable for portable applications and a detachable extension handle adapts it to floor polishing. Two speeds are available and power-driven accessories may be attached for various tool and buffing operations.
