Title:
ELECTRIC TOOL AND POLISHER USING SAME
Document Type and Number:
WIPO Patent Application WO/2015/025677
Kind Code:
A1
Abstract:
Provided are an electric tool and a polisher using the same that are capable of performing polishing such as floor polishing. A motor (3), a housing (2), and a polisher body (200) as a tip tool for an electric tool (1) for which a chuck (12) is rotated by the motor (3) are connected directly or connected indirectly by way of a flexible shaft (101). The electric tool (1) is provided with a rotation controlling mode that is exclusively for polishing operation so as to be provided with a polishing mode to perform constant speed control at approximately 50 to 300 rotations when a trigger is pressed. In polishing mode, to cope with the large inertia of the polisher body (200), acceleration control and deceleration control is performed more mildly in comparison to conventional rotation controlling modes. Furthermore, in polishing mode, the chuck (12) is prevented from becoming loose during acceleration and deceleration by controlling the chuck so as to rotate in one direction only.
