German BOSCH tools BOSCH models BOSCH prices

BOSCH 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, which must be kept sharp to ensure 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-tools) and single-function tools (such as electric planers, jigsaws, circular saws, sanders, and engravers); pneumatic tools include polishers and nail guns; hand tools can be divided into measuring tools, hand saws, woodworking planes, wood files, hand chisels, and sandpaper.

BOSCH tool classification

1) Tools: Magnetic properties of materials are often utilized in production to facilitate operations, such as magnetic screwdrivers used in electronic product assembly. In machining, a large amount of fine iron chips is generated. These chips flow back with the cooling medium into the recovery container, often causing circuit blockages and making cleaning inconvenient. A magnetic oil trough can be installed on the machine tool. During metal cutting, the cooling medium carrying iron chips flows from the worktable drain groove into the oil trough. As it passes through the filter screen, the iron chips are blocked and accumulate on one side of the screen due to the action of ring magnets, while the cooling medium flows into the oil tank through the oil channel. For cleaning, the oil trough can be easily lifted to dump the chips. 2) Molds: When bending and forming workpieces with complex shapes, eccentric centers of gravity may cause instability if the mold is too small, potentially leading to cantilever effects, flipping, or warping. For example, a positioning magnet can be added to the die cavity to assist in workpiece positioning, which reduces mold volume and increases positioning reliability. 3) Auxiliary tools: In stamping production, steel plates stacked together have no gaps and adhere due to atmospheric pressure, making material handling difficult. This problem can be solved by installing a magnetic auxiliary workbench close to the press. The working principle is as follows: a baffle is fixed on the workbench, with a magnet installed on one side. The sheet metal to be processed is placed tightly against the other side of the baffle. During operation, the vertical movement of the press slider and vibrations caused by punching force cause the sheets to vibrate vertically. The top sheet, unable to overcome the magnetic force due to gravity, leans against the baffle, naturally creating a gap for easy material retrieval. The magnetic force can be adjusted by changing the thickness of the baffle. Magnetic force acts like an invisible hand to hold the workpiece. By cleverly using magnet technology, we simplify the structure of various tools, improve the process performance of workpieces, and make production easier, demonstrating that magnetic tools can help achieve unexpected results.

BOSCH tool classification

Explosion-proof tools are internationally known as "safety tools" and "non-sparking tools," and domestically as "explosion-proof tools." Explosion-proof tools produced, sold, and distributed in China can be divided into two main categories based on material: 1. Aluminum-copper alloy (commonly known as aluminum bronze) explosion-proof tools, specifically made of copper-based alloys composed of high-purity electrolytic copper as the base with appropriate amounts of aluminum, nickel, manganese, iron, and other metals. 2. Beryllium-copper alloy (commonly known as beryllium bronze) explosion-proof tools, specifically made of copper-based alloys composed of high-purity electrolytic copper as the base with appropriate amounts of beryllium, nickel, and other metals. Both materials have excellent thermal and electrical conductivity. After heat treatment, the hardness and wear resistance of aluminum bronze are nearly identical to those of beryllium bronze, both reaching above HRC30o. Beryllium bronze is non-magnetic and can be used in strong magnetic field environments. Explosion-proof tools can also be divided into two main categories based on manufacturing process: 1. Casting process: This is a traditional manufacturing process and was the internationally common technology for manufacturing explosion-proof tools in the 80s. Most domestic explosion-proof tool manufacturers continue to use this process today. Advantages of the casting process: simple process and low manufacturing cost. Disadvantages: lower product density, hardness, tensile strength, and torque; more pores and sand holes, resulting in shorter product service life. 2. Forging process: The latest international manufacturing process, which uses large presses or punch presses combined with high-heat-resistant forming molds to forge products in a single step. Advantages of the forging process: significantly improves product density, hardness, tensile strength, and torque; basically eliminates pores and sand holes, extending the mechanical performance and service life of products by approximately 1 times compared to traditional casting processes. Disadvantages: higher investment in equipment and molds, resulting in higher costs.

BOSCH tool usage

1) Plane blade adjustment: When installing the plane blade, first fit the blade with the cap iron, control the distance between their cutting edges, and then insert them into the plane body. With the cutting edge close to the plane sole, add the wedge, press down slightly, hold the left corner of the plane sole with the left hand, and use the thumb to secure the wedge, cap iron, and plane blade. Use a hammer to correct the cutting edge so that it 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 protrusion, lift the plane with the left hand, sole facing up, and look backward with one eye to observe. If the protrusion is inappropriate, lightly tap the upper end of the blade. If it protrudes too much and needs to be retracted, lightly tap the rear end of the plane body. If one corner of the cutting edge protrudes, lightly tap the upper side of the same corner of the blade. 2) Planing techniques: When planing, extend the index fingers of both hands forward to press on the plane body, press the thumbs on the rear part of the blade, and grip the handle tightly with the remaining fingers and palms. Keep the plane body level and apply uniform force with both hands. When pushing forward, increase the force with both thumbs and apply slight pressure with the index fingers. Gradually reduce the pressure as you reach the front end until no pressure is applied. When retracting, slightly lift the rear of the plane to prevent the cutting edge from dragging on the wood surface, which can cause dulling. When planing long stock, place the left foot forward, followed by the right foot. Before planing long stock, check whether the surface is heartwood or sapwood. Generally, heartwood is cleaner and has clearer grain than sapwood. If it is heartwood, plane from the root to the tip; if it is sapwood, plane from the tip to the root. Planing along the wood grain saves effort. Otherwise, it is easy to cause "tear-out," resulting in a rough, uneven surface and requiring excessive effort. When starting to plane, the plane sole should be 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 unevenly, a common mistake among beginners that must be corrected.
