German RALM tools RALM models RALM prices

RALM tools powered by electric motors or electromagnets, driving the working head through a transmission mechanism, are referred to as power tools. They are hand-held operating tools that use low-power electric motors or electromagnets as the power source to drive the working head via a transmission mechanism. Power tools are divided into handheld and portable types; handheld power tools are more flexible, convenient, and widely used. Many varieties have become essential tools for production and daily life. There are numerous power tool brands. According to their functions and applications, they are mainly classified into metal cutting power tools, grinding power tools, assembly power tools, and railway power tools. Common power tools include electric drills, electric grinders, electric wrenches and electric screwdrivers, electric hammers and impact drills, concrete vibrators, and electric planers.

RALM tool classification

1) Tools: In production, magnetic properties of materials are often utilized to facilitate processes, such as magnetic screwdrivers used in electronic product assembly. In machining, large amounts of fine iron chips are generated. These chips flow back with the cooling medium into recovery containers, often causing circuit blockages and making cleanup inconvenient. A magnetic oil trough can be installed on the machine tool. During metal cutting, the cooling medium containing iron chips flows from the worktable drain groove into the oil trough. As it passes through the filter mesh, the iron chips are blocked and accumulate on one side of the mesh due to the action of ring magnets, while the cooling medium flows into the oil tank through oil channels. For cleanup, the oil trough can be easily lifted to dump the chips. 2) Molds: When bending and forming workpieces with complex shapes, offset centers of gravity may cause instability if the mold is too small, potentially leading to cantilever effects, flipping, or warping. For example, adding a positioning magnet to the die cavity can assist in workpiece positioning, reducing mold volume while increasing 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. Installing a magnetic auxiliary workbench close to the press solves this problem. The principle involves fixing a baffle plate on the workbench with a magnet on one side. The sheet metal to be processed is placed tightly against the other side of the baffle. During operation, vibrations caused by the up-and-down movement of the press slider and punching force cause the sheets to vibrate. The top sheet, unable to overcome magnetic force due to insufficient gravity, leans against the baffle, naturally creating a gap for easier material handling. Magnetic force magnitude can be adjusted by changing the baffle thickness. Magnetic force acts like an invisible hand to hold workpieces. By cleverly utilizing magnet technology, we simplify tool structures, improve workpiece process performance, and make production easier, demonstrating that magnetic tools can achieve unexpected results.

RALM tool precautions

Large saws are commonly used for wide and thick wooden boards; small saws are used for narrow and thin lumber; coarse saws are used for cross-cutting; fine saws are used for tenons and shoulders; saws with larger kerf settings are required for hardwoods and wet wood, while saws with smaller kerf settings are used for softwoods and dry wood. When using saws, safe operating methods for each type must be observed: 1) Before using a frame saw, adjust the blade angle with the knob; conventionally, it should form an angle of 45° with the plane of the wooden frame. Tighten the tension rope with the toggle to keep the blade straight and taut. When starting the cut, grip the handle firmly with the right hand and place the left hand at the starting point, gently pushing and pulling a few times. Do not apply excessive force. Do not twist the saw left or right during cutting. Apply heavier pressure on the push stroke and lighter pressure on the pull stroke, maintaining a uniform rhythm. Hold the part being cut off steady with your hand when nearing completion. After use, loosen the blade and hang it in a secure location. 2) When using a crosscut saw, apply balanced force with both hands to prevent the saw from drifting toward the side with greater force. Correct deviations slowly to prevent binding or breaking the blade. 3) When using a coping saw, do not apply excessive force or pull too quickly to avoid breaking the wire blade. During operation, do not position your head above the upper end of the bow frame to prevent facial injury from a snapping blade. 4) Regularly check the sharpness of the blade and the stability of the saw frame and handle. Promptly repair blades with dull or uneven teeth. Repair or replace damaged ropes, nuts, knobs, handles, and wooden frames before continuing use.

RALM tool features

The electronically controlled powerful chuck offers superior holding force, reaching up to 16kg/cm², with uniform and adjustable magnetic distribution. It is suitable for various heavy-duty machining, roughing, and finishing operations. Standard powerful chucks have weaker and uneven holding forces, unable to meet the demands of heavy-duty machining. The holding force of an electronically controlled powerful chuck does not require continuous power supply, generating no heat during continuous operation, thus avoiding thermal deformation of workpieces. Its strong and uniform surface holding force ensures maximum machining precision even if the workpiece overhangs the table. In contrast, standard electromagnetic chucks require continuous current supply, generating heat after prolonged operation. This not only causes thermal deformation of the workpiece but also reduces magnetic holding force, compromising machining precision. Electronically controlled powerful chucks can operate continuously without failure or maintenance, even when running for more than 20 hours per day. Standard permanent magnet chucks typically experience decreased holding force after about six months of use, while electromagnetic chucks can only operate for a few hours daily and are prone to failures, requiring frequent replacement and repair of internal components. Using standard powerful chucks requires significant workpiece adjustment time, accounting for 40%-50% of the entire machining process, often resulting in obvious clamping and positioning errors, high scrap rates, and very low efficiency. Electronically controlled powerful chucks feature automatic auxiliary positioning; simply pressing a button completes workpiece clamping or release in 0.3 seconds, significantly improving production efficiency.
