German calemard tools calemard models calemard prices

calemard tools are made of copper alloy. Due to copper's good thermal conductivity and its characteristic of being almost carbon-free, the heat generated in a short time when the tool rubs against or impacts an object is absorbed and conducted. Another reason is that copper itself is relatively soft, providing good compliance during friction and impact, making it difficult to produce tiny metal particles, so we hardly see any sparks. Therefore, explosion-proof tools are also called non-sparking tools. The materials for explosion-proof tools are beryllium bronze and aluminum bronze. Beryllium bronze alloys and aluminum bronze alloys do not spark upon impact or friction, making them very suitable for manufacturing safety tools used in explosive, flammable, strong magnetic, and corrosive environments. BeA-20C alloy withstands an impact energy of 561IJ in hydrogen containing 30% or in methane air-oxygen containing 6.5-10%, with 20 impacts, without sparking or combustion.

calemard tool classification

1) Electric planer: It is one of the main machines used in woodworking and decoration. It is mainly used for planing smooth surfaces of various woods. Products are divided into short planers and rough planers. Rough planers are mainly used for planing smooth surfaces of straight wood and can process larger board surfaces; short planers, in addition to planing board surfaces, can also be used with various guide plates for planing tongues and grooves, edges, and slotting. The main features of using a handheld electric planer are small size, light weight, portability, and ease of use. Compared with manual tools, it can greatly reduce labor intensity and improve processing efficiency and quality. When using a handheld electric planer, hold the handle at the rear of the planer body with your right hand and slightly raise the center of gravity of the rear part. After starting the power with your left hand, hold the guide handle at the front of the planer, keeping the center of gravity of the front part lower. Follow the operation sequence where the front part of the planer contacts the wood first. When the rear part of the planer steadily contacts the planing surface, push the planer body forward smoothly in the direction of planing with both hands. After the planer body completes the planing stroke, lift the front part of the planer with your left hand, then pick it up with both hands and return to the starting point for planing. Repeat this until all planing is completed. 2) Jigsaw: Also known as electric coping saw, electric fine saw, etc. It is a multifunctional cutting tool that can cut materials on wooden boards, as well as perform straight or curved cuts on plastic and metal sheets. It is particularly effective for cutting complex shapes and geometric figures with small radii of curvature. It is an essential multifunctional sawing tool for home renovation and various public interior decoration projects. It features light weight, small size, portability, simple operation, and wide application range. Its cutting principle involves a narrow saw blade with upward-facing teeth. During operation, the blade moves in a linear reciprocating motion up and down to cut, completing various sawing tasks according to size requirements. If used with a guide plate, it can also perform angled bevel processing. When using an electric jigsaw, for smaller and thinner wooden boards, fix them on a workbench first and support the workpiece with your left hand. Then, hold the saw handle with your right hand and push forward slowly for sawing. Apply steady and uniform force during operation; do not apply excessive force to avoid injury or damage to the blade. For larger boards, ensure the board is fixed securely, then hold the saw handle with both hands and push forward for sawing. Operate along the line, always keeping the blade perpendicular to the board surface to prevent jamming or binding. 3) Circular saw: Also known as a small handheld circular saw. It is a new type of small handheld electric saw equipped with a spring-loaded automatic safety guard and an electronically controlled constant-speed motor. It features simple operation, flexible use, quick adjustment, and safe reliability. It is very suitable for home renovation tasks such as cutting various wooden boards and fiberboards. The thickness of wood or boards to be cut is generally recommended to be below 60mm. 4) Sanding tools: Also known as small handheld grinders. They are mainly used for sanding bare wood before painting various wood veneers, and can also be used for sanding putty surfaces. However, sanding putty generates significant dust, which seriously pollutes the environment, so enhanced labor protection is required during operation. Handheld grinders include belt sanders and orbital sanders. Belt sanders are mainly used for rapid sanding of wooden components and products, while orbital sanders are commonly used for sanding large areas such as wooden floors in home renovations. 5) Small engraving machine: Also known as a groove planner or trimmer. It can be used for slotting, tenoning, drilling, edging, milling, and trimming on various wooden products and components. It can also be used for simple edging, milling, grooving, and trimming on light metal materials such as aluminum alloy and plastic steel, such as aluminum alloy (or plastic steel) doors and windows, balcony frames, and furniture frames. Therefore, it is also one of the commonly used power tools in modern home renovation projects.

calemard tool usage

1) Select the appropriate saw blade according to the workpiece. For example, use 14 teeth per inch for cutting solid or thick soft metals; use 18 teeth per inch for tool steel, iron pipes, and hard metals; and use 24 teeth per inch for cutting metal sheets, metal pipes, and thin iron bars. 2) Push the saw forward, and lift it gently when pulling back. 3) Select wrenches of appropriate size according to the nature of the work. 4) When using an adjustable wrench, apply force towards the fixed jaw, never towards the adjustable jaw. 5) If the wrench opening is worn or slips during use, do not continue to use it to prevent slipping. 6) Do not use a wrench as a hammer for striking. 5. Do not add a pipe to the end of the wrench handle to increase torque. 7) Press the inner side of the first edge of the square ruler against the edge of the wooden board, and draw a vertical line with a pencil along the inner side of the second edge of the square ruler. 8) Select the appropriate screwdriver according to the size and shape of the screw head groove. 9) Do not strike the screwdriver handle with a hammer. Replace handles immediately if damaged. 10) Do not use a screwdriver as a chisel or lever. 11) Use an electrician's screwdriver to test current; do not use a general screwdriver to test high voltage. 12) Do not grind the tip of the screwdriver to avoid damaging the hardened surface. 13) Do not place screwdrivers in shirt or trouser pockets to avoid injury from collision or falling.

1) Carefully inspect before use. Ensure there is no external damage, the switch operates flexibly without sticking, and the power cord and tool housing are intact. Use a 500V megohmmeter to measure the insulation resistance between the winding and the housing, which must not be less than O.5 megohms. See the attached table for insulation resistance values. 2) Handheld power tools with metal housings must have a reliable protective grounding wire. The power cord should be a multi-core soft rubber sheathed cable, and the grounding protection wire at both ends must be connected securely. 3) Handheld power tools should be used by dedicated personnel with certain professional knowledge. Strictly adhere to relevant safety operating procedures during use. 4) Before use, check whether the relevant electrical and mechanical protection devices are intact and functioning normally. Also, ensure that the rotating parts rotate flexibly without sticking. 5) When using Class I handheld power tools, users must wear prescribed protective equipment and set up qualified protective gear. Take corresponding anti-electric shock safety measures as required, such as installing residual current devices in the power circuit, or having users wear insulating gloves, insulating shoes, or stand on insulating mats. When using Class II handheld power tools in damp and narrow places, install a residual current circuit breaker with a working current of less than 1.5mA and an action time of less than or equal to 0.1 seconds. The residual current circuit breaker should be placed inside the container and supervised by dedicated personnel. 6) Occupational hazards of using handheld power tools. Arm vibration disease caused by long-term hand-transmitted vibration operations was listed as one of China's statutory occupational diseases as early as 1957, also known as local vibration disease, typically manifested as episodic white finger.
