German alpine metal tech workpiece clamping fixtures, alpine metal tech models, alpine metal tech prices

alpine metal tech workpiece clamping fixtures are machine tool accessories produced based on the electromagnetic principle. By energizing the internal coil to generate magnetic force, the workpiece in contact with the surface of the magnetically conductive panel is firmly held. De-energizing the coil eliminates the magnetic force, allowing demagnetization and removal of the workpiece. Main applications include workpiece fixation during the machining of ferrous workpieces on grinding machines, electromagnetic knife grinders, gantry milling machines, and gantry planers. Rectangular electromagnetic chucks have lifting screw holes on both sides; during installation, T-shaped screws can be screwed in for lifting. They are fixed to the worktable using T-shaped blocks and screws. Connect the DC power supply and ground wire from the machine tool, then precision grind the upper plane of the chuck once to ensure parallelism between the upper and bottom surfaces. When holding a workpiece, sufficient positioning holding force is achieved by bridging two adjacent magnetic poles, allowing grinding operations. Magnetization and demagnetization of the workpiece can be controlled via the machine tool buttons.

An electromagnetic chuck is an electromagnetic fixture that secures the workpiece being machined through the holding force generated by the chuck body after the electromagnetic coil is energized. The electromagnetic chuck consists of an iron core, coil, panel, and bracket. The electromagnet, composed of the coil and iron core, is the main part of the electromagnetic chuck.

alpine metal tech workpiece clamping fixture features

1) Chuck holding force: The electronically controlled high-power chuck has extremely strong holding force, up to 16kg/cm², with uniform and adjustable magnetic distribution. It is suitable for various heavy-duty machining, roughing, and finishing operations. Standard high-power chucks have weaker and uneven holding force, unable to meet the requirements of heavy-duty machining. 2) Machining precision: The holding force of the electronically controlled high-power chuck does not require continuous power connection to maintain. It generates no heat during continuous operation, avoiding thermal deformation of the workpiece. The strong and uniform surface holding force 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 a period of operation. This causes thermal deformation of the workpiece and a decrease in chuck magnetic force, failing to guarantee machining precision. 3) Performance: The electronically controlled high-power chuck can be used continuously without any faults or maintenance, even when operating continuously for more than 20 hours per day. Standard permanent magnet chucks show a decline in holding force after about half a year of use. Electromagnetic chucks can only operate for a few hours a day, are prone to failures, and require frequent replacement and maintenance of internal components. 4) Operational efficiency: Using standard high-power chucks requires significant time for workpiece adjustment, accounting for 40%-50% of the entire machining process. Clamping and positioning are prone to obvious errors, resulting in high scrap rates and very low efficiency. The electronically controlled high-power chuck features automatic auxiliary positioning. Simply pressing a button completes workpiece clamping or release in 0.3 seconds, significantly improving production efficiency.

alpine metal tech workpiece clamping fixture usage

With the continuous development of China's industry, the use of electromagnetic chucks in industrial production is becoming increasingly widespread. The most important aspects of an electromagnetic chuck are its parameters, particularly the lifting capacity and working class. The lifting capacity of an electromagnetic chuck refers to the maximum weight allowed to be lifted under specified working conditions, also known as the rated lifting capacity. Generally, the lifting capacity of a crane equipped with an electromagnetic chuck should include the weight of the electromagnetic chuck itself. Rectangular electromagnetic chucks have lifting screw holes on both sides; during installation, T-shaped screws can be screwed in for lifting. They are fixed to the worktable using T-shaped blocks and screws. Connect the DC power supply and ground wire from the machine tool, then precision grind the upper plane of the chuck once to ensure parallelism between the upper and bottom surfaces. When holding a workpiece, sufficient positioning holding force is achieved by bridging two adjacent magnetic poles, allowing grinding operations. Magnetization and demagnetization of the workpiece can be controlled via the machine tool buttons. Before using the electromagnetic chuck, wipe the surface clean to avoid scratches. Severe impacts are prohibited to prevent affecting precision. After use, clean the chuck and apply anti-rust oil to prevent corrosion. When using the electromagnetic chuck independently, a ground wire must be connected to prevent electric shock injuries due to leakage.
