German VARTA tools VARTA models VARTA prices

VARTA tools are tools that use compressed air to drive a pneumatic motor and output kinetic energy. According to their basic operating methods, they can be divided into: 1) Rotary type (eccentric movable vane type). 2) Reciprocating type (volume piston type). General pneumatic tools mainly consist of the power output part, operation form conversion part, intake and exhaust path part, operation start and stop control part, tool housing and other main parts. Of course, pneumatic tool operation must also have an energy supply part, air filtration and pressure regulation part, and tool accessories. Main types include impact wrenches (also called pneumatic wrenches, air wrenches, air impact guns), pneumatic screwdrivers (also called pneumatic drivers, air screwdrivers), pneumatic grinders (also called pneumatic polishers, pneumatic wet grinders, pneumatic sanders, pneumatic grinding machines), pneumatic spray guns, pneumatic rivet guns, pneumatic nut setters, air chisels, air hammers, vibration-damping pneumatic saws, and vibration-damping pneumatic files.

VARTA tool classification

1) Tools: In production, magnetic properties of materials are often utilized to facilitate manufacturing, such as magnetic screwdrivers used in electronic product assembly. In machining, a large amount of fine iron chips is generated. These chips flow back with the cooling medium into the recovery container, 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 oil drain groove 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 ring magnets, while the cooling medium flows into the oil tank through the oil channel. For 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 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 and stick together due to atmospheric pressure and other reasons, making material handling very inconvenient. Installing a magnetic auxiliary workbench close to the punch press solves this problem. The working principle is as follows: a baffle is fixed on the workbench, with a magnet installed on one side of the baffle. The sheet metal to be processed is placed closely against the other side of the baffle. During operation, the up-and-down movement of the punch press slider and the vibration caused by the punching force cause the sheet metal to vibrate vertically. Since the gravity of the top sheet is insufficient to overcome the magnetic force, it leans against the baffle, naturally forming a certain gap, which facilitates material handling. The magnetic force can be adjusted by changing the thickness of the baffle. Magnetic force acts like an invisible hand to help hold the workpiece. By cleverly using magnet technology, we simplify the structure of various tools, improve the process performance of workpieces, and make production easier. It is evident that magnetic tools can help us achieve unexpected results.

VARTA tool purchasing guide

1) Distinguish between household and professional use according to needs. Most power tools are designed for professionals. When purchasing, distinguish between professional and general household tools. Usually, the difference between professional and general household tools lies in power. Professional tools have higher power to reduce the workload for professionals. General household tools are used for smaller projects with relatively less workload, so the input power of the tools does not need to be very high. 2) The outer packaging of the tool should have clear patterns, no damage, and a sturdy plastic box. The latch for opening the plastic box should be firm and durable. 3) The appearance of the tool should have uniform color. The surface of plastic parts should have no obvious flow marks or dents, and should not have scratches or collision marks. The assembly misalignment between housing parts should be ≤0.5mm. Aluminum casting coatings should be smooth, aesthetically pleasing, and free of defects. The entire machine surface should be free of oil and stains. When holding by hand, the switch handle should be flat. The length of the cable should generally be no less than 2 meters. 4) The nameplate parameters of the tool should match those on the CCC certificate. The manual should contain the detailed address and contact information of the manufacturer and production plant. The nameplate or certificate of conformity should have a traceable batch number for the product. 5) Hold the tool by hand, connect to power, and frequently operate the switch to start the tool repeatedly. Observe whether the on/off function of the tool switch is reliable. At the same time, observe whether there are any abnormal phenomena in nearby televisions or fluorescent lamps to confirm whether the tool is equipped with an effective radio interference suppressor. 6) Run the tool for one minute. While running, hold it by hand; you should not feel any abnormal vibration. Observe the commutation sparks; the commutation spark level should not exceed level 3/2. Generally, looking inward from the air inlet of the tool, there should be no obvious arcing on the commutator surface. During operation, there should be no abnormal noise.

VARTA tool usage

1) When placing the diamond dressing tool head into the holder, be careful not to impact the grinding wheel surface. 2) Do not align the single-point diamond dressing tool head vertically with the center of the grinding wheel; it generally needs to be tilted 10-15°. 3) Do not "quench" (i.e., suddenly cool) a heated dressing tool. During dry dressing, the interval between two dressings must be sufficient to allow the heated dressing tool to cool. 4) Do not assume that the grinding wheel surface has ideal flatness. At the beginning of dressing, find the high point of the grinding wheel and perform dressing. 5) If possible, the amount of removal from the grinding wheel each time should not exceed 0.001 inches on the radius of the grinding wheel. Excessive removal can cause premature wear and frequent breakage of the diamond dressing tool head. 6) However, do not remove too little material each time. Grinding wheels used on old or poorly rigid machine tools may not require dressing. 7) Note that you should not stay in one position for too long during dressing. This will polish the grinding wheel surface, generate high temperatures, and damage the diamond dressing tool. Rotate the dressing tool at least once a day. 8) Do not continue to use worn or damaged dressing tools. Adjust or replace them in time. 9) Do not choose excessive removal amounts and too fast lateral feed speeds during rough dressing, and then choose small removal amounts and slow lateral feed speeds during fine dressing. This will quickly damage the diamond dressing tool. If possible, it is recommended to choose the same lateral feed speed for both rough and fine dressing.
