Left offset knife: when the knife is flat, the blade is on the left.

Right offset knife: when the knife is flat, the blade is on the right.

Difference:

1, different deviation directions?

When the tip of the left-leaning knife rushes to the user, the blade is left, that is, left; The blade on the right is a right-sided knife.

2. The cutting direction is different during machining.

Left offset tool: turning the outside diameter of the workpiece from left to right.

Right offset tool: turning the outside diameter of the workpiece from right to left.

Sharpening method

1, people stand on the edge of the grinder to prevent the grinding wheel from breaking and debris flying out to hurt people;

2. Let go of the distance between the hands holding the knife and hold the waist with two elbows to reduce the jitter when sharpening the knife;

3. Move horizontally. When the turning tool leaves the grinding wheel, the turning tool should be lifted upward to prevent the grinded blade from being scratched by the grinding wheel;

4. When grinding the cutter face, the tail of the cutter bar deviates to the left by a main deflection angle; When grinding the flank of the cutter pair, the tail of the cutter bar is offset to the right by an auxiliary offset angle;

5, grinding tool tip arc, usually with the left hand holding the front end of the turning tool as the fulcrum, the right hand turning the tail of the turning tool.

Strengthen safety knowledge:

1 Before sharpening the knife, check whether there is any crack on the grinding wheel and whether the nut of the grinding wheel shaft is tightened, and then use it after trial operation, so as to prevent the grinding wheel from breaking or flying out and hurting people.

2. The sharpening tool should not be too hard, otherwise it will make the hand slip and touch the surface of the grinding wheel, causing industrial accidents.

3, should wear protective glasses when sharpening, so as to avoid gravel and iron filings fly into the eyes.

4. Don't stand facing the rotating direction of the grinding wheel when sharpening the knife to prevent accidents.

5. When grinding the cutter head, the cutter head must be placed on the cutter bar.

6. The clearance between the grinding wheel bracket and the grinding wheel shall not be greater than 3 mm If it is found to be too large, it should be adjusted appropriately.
