Portable electric rotory disc cutting machine for building materials

摘要

Within a casing (1) under the working surface (6) on which materials are placed for cutting, a tank (24) is pivoted about a lengthwise horizontal axis between two end holes (18,19) and can be secured at any angle within a 45 deg. range by a knurled nut (41) in an arcuate slot (40). The adjustment determines the cutting angle of the diamond disc (65) rotated by a milling machine (55) which is screwed to a normally-vertical wall (27) of the tank (24). - The disc works through a lengthwise slot in the surface . The opposite edge of the disc dips into a small quantity of water in the tank for cooling.
