Precision cut off machine

摘要

The precision cut off machine (10) includes a spindle shaft (24) rotatably journaled on a platform (12). A motor (30) drives the spindle (24) through a cogged belt (36) trained around cogged pulleys (38 and 40). A flexible abrasive cutting disk (64) is attached to the end of the spindle opposite the cogged pulley 40. A fixed workpiece support (70) with a disk slot (74) is pivotally attached to the platform (12) by a hinge assembly (72) and locked in place with the radially outer edge of the disk (64) in the slot. A pump (88) supplies coolant to a wand (92) for cooling a workpiece during cutting. A workpiece is placed on the support (70) and manually advanced for cutting. A fence assembly (116) can be employed to set the length of workpiece. To cut flagged and headed workpieces, a step riser assembly (154) can be used. The fence assembly (116) can be used with the riser (154). A v-block assembly (170 with an adjustable stop (210) can be used on the support (70). The v-block has adjustable disk guides (200 and 206).
