Embodiment Construction

[0018] see first figure 1 and figure 2 , which illustrates cutting unit 2. The cutting unit comprises a base 4 with a turntable 6 . The top surface of the turntable and the top surface of the base form a surface 8 for receiving a workpiece (not shown) to be cut. The base includes a slot 10 for receiving a circular blade (not shown) on the cutting head 14 therein when the cutting head is moved to the covered cutting position. The cutting head 14 is provided with a guard 16 having a movable portion 18 to expose the blade for cutting.

[0019] The cutting head is provided on a pivot base 20 for movement between a raised position as shown and a lowered cutting position in the direction of arrow 22 in which direction the blade enclosing the blade in the raised position is removed. A portion of the lower guard 18 to expose the blade and allow the blade to enter the workpiece as the blade rotates to perform the cutting operation. The cutting unit may be provided with a bevel an...

Abstract

The invention relates to miter saw, composite saw, or hack saw devices. It includes motive cutting head set on sliding block to make it move relative to the base seat. The sliding block has at least one outer slender flat surface which can be used as cutting head guide surface.

Description

technical field [0001] The invention to which this application relates is a power saw apparatus, of the type comprising a base and a cutting head housing a rotatable circular blade. The cutting head is movable between a raised position and a lowered cutting position for cutting a workpiece mounted on the base. Saws of this type include chop saws, compound saws and miter saws. Background technique [0002] The cutting unit comprises a base, usually with a turntable that rotates relative to the remainder of the base. The top surface of the base and the turntable form a surface on which the workpiece to be cut rests. Fences or fences may be provided on the surface to serve as vertical positioning for the edge of the workpiece. In the direction towards the rear of the base there is provided a mount on which the cutting head rests. The cutting head may be arranged in a fixed position relative to the horizontal plane or may comprise one or more sliding parts, and it is to this...
