German RAMI tools RAMI models RAMI prices

RAMI tools powered by electric motors or electromagnets, driving the working head through a transmission mechanism, are referred to as power tools. These are hand-held tools operated using low-power electric motors or electromagnets as the power source, driving the working head via a transmission mechanism. Power tools are categorized into handheld and portable types; handheld power tools offer greater flexibility, convenience, and wider application. Many varieties have become essential tools for production and daily life. With numerous power tool brands available, they are primarily classified by function and usage into metal cutting power tools, grinding power tools, assembly power tools, and railway-specific power tools. Common power tools include electric drills, electric grinders, electric wrenches and screwdrivers, electric hammers and impact drills, concrete vibrators, and electric planers.

RAMI tool classification

1) Squeeze-exhaust suction cups rely on downward squeezing force to expel all air from the cup, 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 strong, making them suitable mainly for workpieces that are not too large in size, thin, and light. 2) Airflow negative pressure suction cups use an airflow control valve to inject 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 connect the vacuum pump to the suction cup via an electromagnetic control valve. When the control valve evacuates air, negative pressure forms inside the cup to hold the object. Conversely, when the control valve connects the cup to the atmosphere, the suction is lost, releasing the workpiece. The suction force of vacuum pump suction cups mainly depends on the adsorption area of the cup and the vacuum degree inside the cup (referring to the thinness of the air in the q cavity). This type of suction cup offers reliable operation and strong suction but requires a vacuum pump and airflow control system, resulting in higher costs. 4) Mechanical clamping: The structure of a straight-bar dual-cylinder translational gripper involves fingers 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 toward the center, clamping the workpiece; when no pressurized gas is present, springs push the two pistons outward, releasing 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 workstations.

RAMI tool usage

1) Rip cutting method: 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 use 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 penetrated 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 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 bend or the kerf face may be uneven. 2) Crosscutting method: When sawing, place the wood on a bench, stand to the left rear 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 motion 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 about 75°–90° (relative to the wood surface); for crosscutting, the blade tilts backward at an angle of about 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 cutoff piece with your left hand, slow down the sawing speed, and complete the cut entirely. Do not leave any material to break off naturally or snap it by hand, as this can damage the saw blade and cause the wood to split along the grain, affecting quality.

RAMI tool usage

1) When placing the diamond dressing tool holder into the chuck, avoid impacting the grinding wheel surface. 2) Do not align the single-point diamond dressing tool vertically with the grinding wheel center; generally, it should be tilted at 10-15°. 3) Do not "quench" (suddenly cool) a heated dressing tool. During dry dressing, maintain sufficient interval time between dressings to allow the heated tool to cool. 4) Do not assume the grinding wheel surface is ideally flat. At the start of dressing, locate the high points on the wheel and dress accordingly. 5) If possible, the material removal amount per dressing should not exceed 0.001 inches on the wheel radius. Excessive removal can cause premature wear and frequent fracture of the diamond dressing tool. 6) However, do not remove too little material each time. Grinding wheels used on old or less rigid machines may not require dressing. 7) Avoid staying in one position too long during dressing, as this polishes the wheel surface, generates high temperatures, and damages the diamond dressing tool. Rotate the dressing tool at least once daily. 8) Do not continue using worn or damaged dressing tools. Adjust or replace them promptly. 9) Do not select excessive removal amounts and fast lateral feed rates for rough dressing, followed by small removal amounts and slow lateral feed rates for fine dressing. This will quickly damage the diamond dressing tool. If possible, it is recommended to use the same lateral feed rate for both rough and fine dressing.
