German ABRASIVI SPECIALI tools, ABRASIVI SPECIALI models, ABRASIVI SPECIALI prices

ABRASIVI SPECIALI 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 physical workload of employees. For some workpieces, clamping is inconvenient during machining and assembly due to their structural characteristics. By vertically positioning a U-shaped iron core on the worktable for processing, simply embedding a magnet in the locating block of the fixture allows the workpiece to be firmly held by magnetic attraction on the worktable equipped with the locating block, while ensuring 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.

ABRASIVI SPECIALI Tool Classification

1) Tools: In production, the magnetic properties of materials are often utilized to facilitate operations, such as using magnetic screwdrivers during electronic product assembly. Machining generates a large amount of fine iron chips, which flow back into recovery containers with the cooling medium, often causing circuit blockages and making cleanup inconvenient. Installing a magnetic oil trough on the machine tool can address this. During metal cutting, the cooling medium carrying iron chips flows from the worktable's oil drain into the trough. As it passes through the filter screen, the iron chips are blocked and accumulate on one side due to the action of ring magnets, while the cooling medium flows into the oil tank through the oil channel. Cleanup is convenient: simply lift the oil trough and dump the chips. 2) Molds: When bending and forming workpieces with complex shapes, offset centers of gravity can cause instability if the mold is too small, potentially leading to cantilever effects, flipping, or warping. For example, adding a positioning magnet to the concave die can assist in workpiece positioning, reducing mold volume while increasing positioning reliability. 3) Auxiliary Devices: In stamping production, steel plates stacked together have no gaps and adhere due to atmospheric pressure, making material handling extremely inconvenient. Installing a magnetic auxiliary worktable closely against the press solves this problem. The working principle involves fixing a baffle plate on the worktable, with a magnet installed on one side. The plates to be processed are placed tightly against the other side of the baffle. During operation, the vertical movement of the press slider and vibrations from punching forces cause the plates to vibrate vertically. The top plate, unable to overcome the magnetic force due to insufficient gravity, leans against the baffle, naturally creating a gap for easy material handling. The magnetic force magnitude can be adjusted by changing the baffle thickness. Magnetic force acts like an invisible hand to hold the workpiece. By cleverly utilizing magnet technology, we simplify the structure of various tools, improve the technological performance of workpieces, and make production easier, demonstrating that magnetic tools can yield unexpected benefits.

ABRASIVI SPECIALI Tool Structure and Composition

The cross-sectional shape and distribution of pole cores vary depending on the workpiece. Common structures for electromagnetic chucks include rectangular and circular types. Rectangular magnetic poles are arranged either longitudinally or transversely. Longitudinal arrangement of rectangular magnetic poles is suitable for securing larger workpieces; transverse arrangement is suitable for securing smaller workpieces. Circular chucks are suitable for securing ring-shaped workpieces or workpieces with complex shapes. The main characteristics of standard electromagnetic chucks are: magnetic flux lines are evenly distributed across the disk surface, magnetic attraction cannot be concentrated, and the magnetic force per unit area is relatively small; the direction of magnetic force is perpendicular to the chuck surface and difficult to change, producing only one type of magnetic force for workpieces with the same contact area; the point of application of magnetic force is limited to the contact surface between the workpiece and the chuck and cannot be arbitrarily changed. Therefore, machining with standard electromagnetic chucks suffers from disadvantages such as low positioning accuracy, insufficient clamping force, narrow scope of application, and low production efficiency.

ABRASIVI SPECIALI Tool Features

Electro-permanent chucks offer ultra-strong holding force, up to 16kg/cm², with uniform and adjustable magnetic distribution, making them suitable for various heavy-duty machining, roughing, and finishing operations. Standard powerful chucks have weaker and unevenly distributed holding force, unable to meet the demands of heavy-duty machining. Electro-permanent chucks do not require a continuous power supply to maintain holding force, generating no heat during continuous operation, thus avoiding thermal deformation of workpieces. Their strong and uniform surface suction ensures the highest machining precision even if the workpiece overhangs the table. In contrast, standard electromagnetic chucks require a continuous current supply, generating heat after prolonged operation. This not only causes thermal deformation of the workpiece but also reduces the chuck's magnetic force, compromising machining precision. Electro-permanent chucks can operate continuously without failure or maintenance, even when running 20 hours or more per day. Standard permanent magnetic chucks typically experience a decline in holding force after about six months of use, while electromagnetic chucks can only operate for a few hours daily and are prone to malfunctions, 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, and clamping positioning is prone to obvious errors, resulting in high scrap rates and very low efficiency. Electro-permanent chucks feature automatic auxiliary positioning; simply pressing a button completes workpiece clamping or release in 0.3 seconds, significantly improving production efficiency.
