German linig tools linig models linig prices

linig tools utilize electromagnetic technologies such as permanent magnets to assist in mechanical manufacturing processes. They can be categorized into magnetic fixtures, magnetic tools, magnetic molds, and magnetic auxiliary devices. The use of magnetic tools can significantly improve production efficiency and reduce the labor intensity of employees. For some workpieces, clamping is inconvenient during machining and assembly due to their structural characteristics. By vertically positioning the U-shaped iron core on the worktable for processing, we only need to embed a magnet in the locating block of the fixture to firmly attract the workpiece to the worktable equipped with the locating block and ensure accurate positioning. This greatly simplifies the fixture structure and improves work efficiency. Some products require welding small parts onto the workpiece; if accurate positioning is not achieved, it not only makes the work difficult but also fails to meet requirements.

linig Tool Classification

1) Tools: In production, the magnetic properties of materials are often utilized to facilitate production, such as magnetic screwdrivers used in electronic product assembly. Machining generates a large amount of fine iron chips. These chips flow back into the recovery container with the cooling medium, 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 containing iron chips flows from the worktable drain into the oil trough. When passing through the filter mesh, the iron chips are blocked and accumulated on one side of the filter mesh due to the action of the ring magnet, while the cooling medium flows into the oil tank through the oil channel. During cleaning, the oil trough can be easily lifted to dump the chips. 2) Molds: When bending and forming workpieces with complex shapes, if the center of gravity is offset and the mold is too small, it may cause a cantilever effect, leading to unstable placement of the workpiece and causing flipping or warping. For example, a positioning magnet can be added to the concave die to assist in workpiece positioning, which reduces the mold volume and increases positioning reliability. 3) Auxiliary Equipment: In stamping production, steel plates used for processing are stacked together without gaps. Due to atmospheric pressure and other reasons, the plates stick together, making material handling extremely inconvenient. Installing a magnetic auxiliary worktable close to the press solves the above problem. The working principle is as follows: a baffle is fixed on the worktable, with a magnet installed on one side of the baffle. The plate to be processed is placed closely against the other side of the baffle. During operation, the up-and-down movement of the press slider and the vibration caused by the punching force cause the plates to vibrate vertically. The top plate, due to insufficient gravity to overcome the magnetic force, leans against the baffle, naturally forming a certain gap, making material handling convenient. The magnetic force can be adjusted by changing the thickness of the baffle. Magnetic force acts like an invisible hand to help us hold the workpiece. By cleverly using magnet technology, we simplify the structure of various tools and improve the process performance of workpieces, making production easier. It is evident that magnetic tools can help us achieve unexpected results.

linig Tool Structure Composition

The cross-sectional shape and distribution of the pole cores vary depending on the workpiece. Common structures of electromagnetic chucks include rectangular and circular types. Rectangular magnetic poles are further divided into longitudinal and horizontal arrangements. Longitudinal arrangement of rectangular magnetic poles is suitable for fixing larger workpieces; horizontal arrangement of rectangular magnetic poles is suitable for fixing smaller workpieces. Circular chucks are suitable for fixing ring-shaped workpieces or workpieces with complex shapes. The main characteristics of ordinary electromagnetic chucks are: magnetic field lines are evenly distributed on the surface of the magnetic disk, the electromagnetic suction force cannot be concentrated, and the magnetic force per unit area is relatively small; the direction of the magnetic force is perpendicular to the chuck surface and difficult to change, producing only one type of magnetic force for workpieces of the same suction area; the action point of the magnetic force on the workpiece is limited to the contact surface between the workpiece and the chuck and cannot be changed arbitrarily. Therefore, during processing, there are disadvantages such as low positioning accuracy, insufficient clamping force, narrow scope of application, and low production efficiency.

linig Tool Features

The electrically controlled powerful chuck has super strong holding force, up to 16kg/cm², with uniform and adjustable magnetic field distribution. It is suitable for various heavy-duty machining, rough machining, and finish machining. Ordinary powerful chucks have weaker and unevenly distributed suction force, unable to meet the requirements of heavy-duty machining operations. The holding force of the electrically controlled powerful chuck does not require a power connection to maintain. It generates no heat during continuous operation, avoiding thermal deformation of the workpiece. Meanwhile, the strong and uniform surface suction force ensures the highest machining precision even if the workpiece extends beyond the table surface. In contrast, ordinary electromagnetic chucks require a continuous supply of current, generating heat after a period of operation. This not only causes thermal deformation of the workpiece but also reduces the chuck's magnetic force, failing to guarantee machining precision. The electrically controlled powerful chuck can be used continuously. Even if it operates continuously for more than 20 hours a day, no faults will occur, and no maintenance is required. Ordinary permanent magnet chucks will experience a decline in suction force after about half a year of use. Electromagnetic chucks can only operate for a few hours a day, and the equipment is prone to failures, requiring frequent replacement and repair of internal components. Using ordinary powerful chucks requires a significant amount of workpiece adjustment time, accounting for 40%-50% of the entire machining process. Clamping and positioning are prone to obvious errors, resulting in a high scrap rate and very low efficiency. The electrically controlled powerful chuck has an automatic auxiliary positioning function. Simply pressing a button completes the clamping or releasing of the workpiece in 0.3 seconds, greatly improving production efficiency.
