German BESSEY tools BESSEY models BESSEY prices

BESSEY tools refer to implements used in woodworking. They generally have sharp cutting edges, so safety must be prioritized during use. Frequent sharpening is required, especially for plane blades and chisels; keeping them sharp ensures both ease of use and quality, as the saying goes, "sharpening the axe does not delay the woodcutting." Woodworking tools are categorized into power tools, pneumatic tools, and hand tools. Power tools can be divided by function into multi-function tools (multi-purpose tools) and single-function tools (such as electric planers, jigsaws, circular saws, sanders, and engravers); pneumatic tools include polishers and nailers; hand tools include measuring tools, hand saws, woodworking planes, wood files, hand chisels, and sandpaper.

BESSEY tool classification

1) Squeeze-exhaust suction cups expel all air from the cup by downward squeezing force, creating a negative pressure state inside to hold the workpiece. Advantages include simple structure, light weight, and low cost. However, the suction force is not large, making them suitable for workpieces that are not too large in size, thin, and light. 2) Airflow negative pressure suction cups: An airflow control valve injects compressed air from an air pump through a nozzle, forming a high-speed jet that removes air from the suction cup cavity, creating negative pressure to hold the object. If compressed air is available at the worksite, using this type of suction cup is convenient and low-cost. 3) Vacuum pump exhaust suction cups: These use an electromagnetic control valve to connect the vacuum pump to the suction cup. When the control valve evacuates air, negative pressure forms in the cup cavity to hold the object. Conversely, when the control valve connects the cup to the atmosphere, the suction is lost and the workpiece is released. The suction force of vacuum pump suction cups mainly depends on the adsorption area of the cup and the degree of vacuum in the inner q cavity (referring to the rarefaction of air). This type of suction cup is reliable and provides strong suction, but requires a vacuum pump and airflow control system, resulting in higher costs. 4) Mechanical clamping: Structure of a straight-bar dual-cylinder translational gripper. The gripper fingers are mounted on a straight bar with finger mounting seats. When pressurized gas enters the rod-side chambers of the single-acting dual cylinders, the two pistons move inward to clamp the workpiece; when no pressurized gas is present, springs push the pistons outward to release the workpiece. A flow divider valve is installed in the cylinder intake line to ensure synchronized piston movement. This type of end effector is used in loading and unloading assembly stations.

BESSEY tool usage

1) Rip cutting: When sawing, place the wood on a bench, step on it with your right foot perpendicular to the cut line, stand straight with your left foot at a 60° angle to the cut line, keep your right hand perpendicular to your right knee, and position your body at approximately a 45° angle to the cut line. Lean forward slightly and move naturally, avoiding leaning left or lunging right. Hold the saw with your right hand and place your left thumb against the blade for positioning. Gently pull and push the saw a few times (pull first, then push) to start the kerf, then remove your left hand from the edge. When the teeth have cut about 5mm into the wood, use your left hand to assist your right hand in lifting and pushing the frame saw. Lift lightly, raising the saw hand slightly; push with more force, applying coordinated effort from the wrist, elbow, shoulder, and waist in a rhythmic manner. This ensures the saw blade follows the cut line. Otherwise, the edge of the rip-cut wood may become curved or uneven, or the kerf surface may be inconsistent. 2) Cross-cutting: When sawing, place the wood on a bench, stand to the rear left of the wood, hold the wood with your left hand, hold the saw with your right hand, and step on the wood with your left foot. The sawing method is the same as for rip cutting. When using a frame saw, the lower end of the blade should tilt forward. For rip sawing, the upper end of the blade tilts backward at an angle of approximately 75°—90° (angle with the wood surface); for cross-cutting, the blade tilts backward at an angle of approximately 30°—45°. Always ensure the blade follows the line without deviation. Keep the kerf straight and avoid swaying the blade left or right, which causes skewing. When the wood is nearly severed, stabilize the offcut with your left hand, slow down the sawing speed, and cut completely through. Do not leave any material to break off or snap by hand, as this can damage the blade and cause the wood to split along the grain, affecting quality.

1) Plane blade adjustment: When installing the plane blade, first fit it properly with the cap iron, controlling the distance between their cutting edges, then insert it into the plane body. Bring the cutting edge close to the sole, add the wedge, and press down slightly. Hold the left corner of the sole with your left hand, using your thumb to secure the wedge, cap iron, and blade. Tap with a hammer to adjust the blade so that the cutting edge protrudes from the mouth. The amount of protrusion is proportional to the cutting depth: more for rough planing, less for fine planing. To check the blade protrusion, lift the plane with your left hand, sole facing up, and sight along it with one eye. If the protrusion is inappropriate, tap the top end of the blade lightly. If it protrudes too much and needs retraction, tap the rear end of the plane body lightly. If one corner of the edge protrudes, tap the upper side of the same corner of the blade. 2) Planing technique: When planing, extend the index fingers of both hands forward to press on the plane body, press the thumbs on the rear of the blade, and grip the handles firmly with the remaining fingers and palms. Keep the plane body level and apply uniform force with both hands. When pushing forward, increase pressure with both thumbs and apply slight pressure with the index fingers; gradually reduce pressure towards the front until no pressure is applied. When retracting, lift the rear of the plane slightly to prevent the blade from dragging on the wood surface, which can dull it. When planing long stock, step forward with the left foot, followed by the right. Before planing long stock, determine whether the surface is heartwood or sapwood; generally, heartwood is cleaner with clearer grain. If it is heartwood, plane from the root end to the tip end; if it is sapwood, plane from the tip end to the root end. Planing along the grain direction saves effort. Otherwise, tear-out may occur, resulting in a rough, uneven surface and excessive effort. During planing, keep the sole tightly against the wood surface. Do not lift the front of the plane at the start, and do not let the front dip at the end (commonly known as "nodding"). Otherwise, the middle part of the planed surface will bulge, a common mistake among beginners that must be corrected.
