Table cutting machine

A cutting machine comprising:

• a table including an upper surface which is configured to receive workpiece;
• a positioning fence vertically extending from the table;
• a cutting machine body including a circular blade having a rotational axis, the cutting machine body being movably supported above the table and capable of vertical movement, wherein the cutting machine body includes at least an upward waiting position and a lower end position, the lower end position being a position where the cutting machine body is moved a maximum vertical distance in a direction from the upward waiting position toward the table, the cutting machine body further including:
• a fixed cover positioned around a first portion of the circular blade;
• a movable cover positioned around a second portion of the circular blade;
• an auxiliary cover positioned around a third portion of the circular blade, wherein:
• the auxiliary cover has a lower end portion that includes a front lower end, a rear lower end, and a top arranged between the front lower end and the rear lower end, the rear lower end extending at an oblique angle to the front lower end so that the lower end portion of the auxiliary cover has a substantially angular shape with the top protruding downward,
• when the cutting machine body is in the lower end position, the front lower end of the auxiliary cover extends substantially parallel to the upper surface of the table,
• when the cutting machine body in the lower end position moves backward, the rear lower end of the auxiliary cover is configured to contact at least one of the positioning fence and the workpiece, so that the auxiliary cover moves upwards and the front lower end of the auxiliary cover moves within the fixed cover,
• the rear lower end has a flat edge extending at an oblique angle to a flat edge of the front lower end so that the lower end portion of the auxiliary cover has the substantially angular shape with the top protruding downward,
• when the cutting machine body is in the upward waiting position, the flat edge of the rear lower end of the auxiliary cover extends substantially parallel to the upper surface of the table, and
• when the cutting machine body is in the lower end position, the flat edge of the front lower end of the auxiliary cover extends substantially parallel to and is spaced vertically upward of the upper surface of the table.
