German UNESA tools UNESA models UNESA prices

UNESA 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 power sources 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.

UNESA tool classification

1) Tools: In production, magnetic properties of materials are often utilized to facilitate operations, 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 creating inconvenience for cleaning. 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 cleaning, the oil trough can be easily lifted to dump the chips. 2) Molds: When bending and forming workpieces with complex shapes, eccentric center of gravity may occur. If the mold is too small, it may cause a cantilever effect, leading to unstable workpiece placement, flipping, or warping. For example, a positioning magnet can be added to the die cavity to assist in workpiece positioning, which reduces the mold volume and increases positioning reliability. 3) Auxiliary tools: In stamping production, steel plates stacked together have no gaps between them. Due to atmospheric pressure and other factors, the plates stick together, making material handling extremely inconvenient. This problem can be solved by installing a magnetic auxiliary workbench close to the press. The working principle is as follows: a baffle is fixed on the workbench, with a magnet installed on one side of the baffle. The plates to be processed are placed closely against the other side of the baffle. During operation, the vertical movement of the press slider and vibrations caused by 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 forming a certain 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 process performance of workpieces, and make production easier. Thus, magnetic tools can help us achieve unexpected results.

UNESA tool maintenance

1) Correct air supply system: The inlet pressure at the tool entrance (not the compressor outlet pressure) is generally 90PSIG (6.2Kg/cm^2). Pressure that is too high or too low will impair tool performance and service life. The intake air must contain sufficient lubricating oil to ensure adequate lubrication of the pneumatic motor inside the tool (a white paper can be placed at the tool exhaust to check for oil stains; the presence of oil stains is normal). The intake air must be free of moisture; using compressed air without an air dryer is inappropriate. 2) Do not arbitrarily disassemble tool parts before operation, as this may affect operator safety and cause tool damage. 3) If the tool has minor faults or fails to achieve its original function after use, do not continue using it; inspect it immediately. 4) Regularly (approximately once a week) inspect and maintain the tool. Add grease (Grease) to rotating parts such as bearings, and add oil (Oil) to the pneumatic motor parts. 5) When using various tools, strictly adhere to all safety regulations and operating instructions. 6) Select appropriate tools for the job. Tools that are too large can easily cause work injuries, while tools that are too small can easily lead to tool damage.

UNESA tool features

The electronically controlled powerful 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. Ordinary powerful chucks have weaker and uneven holding force, unable to meet the requirements of heavy-duty machining. The holding force of the electronically controlled powerful chuck does not require a continuous power connection to maintain, generating no heat during continuous operation, thus avoiding thermal deformation of the workpiece. Meanwhile, the strong and uniform surface holding 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 electronically controlled powerful chuck can be used continuously; even if operated continuously for more than 20 hours per day, no failures will occur, and no maintenance is required. Ordinary permanent magnet chucks typically experience a decline in holding force after about half a year of use, while electromagnetic chucks can only operate for a few hours per day. Furthermore, such equipment is prone to malfunction, requiring frequent replacement and repair of internal components. Using ordinary 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. The electronically controlled powerful chuck features automatic auxiliary positioning. Simply pressing a button completes workpiece clamping or release in 0.3 seconds, significantly improving production efficiency.
