hauff technik clamping fixtures, German hauff technik models, hauff technik pricing

hauff technik clamping fixtures are machine tool accessories that operate on electromagnetic principles. Energizing internal coils generates magnetic force, which passes through a magnetically conductive panel to securely hold workpieces in contact with the panel surface. De-energizing the coils eliminates the magnetic force, allowing demagnetization and workpiece removal. Primary applications include workpiece fixation during machining of ferrous materials on grinders, electromagnetic knife grinders, gantry milling machines, and gantry planers. Rectangular electromagnetic chucks have lifting screw holes on both sides; insert T-head screws for lifting, and secure to the workbench using T-head blocks and screws. Connect the DC power supply and ground wire from the machine tool, then precision grind the upper surface of the chuck once to ensure parallelism between the top and bottom surfaces. When holding workpieces, 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.

hauff technik clamping fixture requirements

Whether clamping or suction-based, robotic end-effectors must meet the repeatability accuracy required for the task. The structure of the robotic end-effector should be as simple, compact, and lightweight as possible to reduce the load on the arm. Specialized, general-purpose robotic end-effectors have simpler structures and high work efficiency, capable of performing various tasks. In contrast, "universal" end-effectors may have disadvantages such as complex structures and high costs. Therefore, the design and use of serialized, standardized, specialized robotic end-effectors with quick-change capabilities is recommended. If an object has two opposing flat surfaces, a dual-jaw parallel gripper can be used to address dimensional deviations. Dual-jaw grippers can also be used for cylindrical objects. Note that retaining or encompassing gripping requires less force.

hauff technik clamping fixture features

1) Chuck holding force: Electrically controlled powerful chucks offer superior holding force, up to 16kg/cm², with uniform and adjustable magnetic distribution. They are suitable for various heavy-duty machining, roughing, and finishing operations. Standard powerful chucks have weaker and uneven holding force, unable to meet heavy-duty machining requirements. 2) Machining accuracy: The holding force of electrically controlled powerful chucks does not require continuous power supply, generating no heat during continuous operation, thus avoiding thermal deformation of the workpiece. The strong and uniform surface holding force ensures highest machining accuracy even if the workpiece overhangs the table. In contrast, standard electromagnetic chucks require continuous current, generating heat over time. This causes workpiece thermal deformation and reduces chuck magnetic force, compromising machining accuracy. 3) Operational performance: Electrically controlled powerful chucks can operate continuously without failure or maintenance, even for more than 20 hours daily. Standard permanent magnet chucks show reduced holding force after about half a year of use. Electromagnetic chucks can only operate for a few hours daily, are prone to failures, and require frequent replacement and maintenance of internal components. 4) Operational efficiency: Using standard powerful chucks requires significant workpiece adjustment time, 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. Electrically controlled powerful chucks feature automatic auxiliary positioning. Simply pressing a button completes workpiece clamping or release in 0.3 seconds, significantly improving production efficiency.

hauff technik clamping fixture usage

With the continuous development of industry in China, the use of electromagnetic chucks in industrial production is becoming increasingly widespread. The most important aspects of an electromagnetic chuck are its parameters, particularly its 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. For cranes equipped with electromagnetic chucks, the lifting capacity should include the weight of the chuck itself. Rectangular electromagnetic chucks have lifting screw holes on both sides; insert T-head screws for lifting, and secure to the workbench using T-head blocks and screws. Connect the DC power supply and ground wire from the machine tool, then precision grind the upper surface of the chuck once to ensure parallelism between the top and bottom surfaces. When holding workpieces, 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. Clean the surface before use to prevent scratches. Avoid severe impacts to maintain accuracy. Clean and apply anti-rust oil after use to prevent corrosion. When using an electromagnetic chuck independently, ensure a ground connection is present to prevent electric shock hazards.
