German JOKARI tools JOKARI models JOKARI prices

JOKARI tools are made of copper alloy. Due to the good thermal conductivity of copper and its characteristic of being almost carbon-free, the heat generated in a short time when the tool rubs against or impacts an object is absorbed and conducted. Another reason is that copper itself is relatively soft, providing good compliance during friction and impact, making it difficult to produce tiny metal particles, so we hardly see any sparks. Therefore, explosion-proof tools are also called non-sparking tools. The materials for explosion-proof tools are beryllium bronze and aluminum bronze. Beryllium bronze alloys and aluminum bronze alloys do not spark upon impact or friction, making them very suitable for manufacturing safety tools used in explosive, flammable, strong magnetic, and corrosive environments. BeA-20C alloy withstands an impact energy of 561IJ in hydrogen containing 30% or in methane-air-oxygen containing 6.5-10%, undergoing 20 impacts without sparking or ignition.

JOKARI tool structure composition

The cross-sectional shape and distribution of the pole cores vary depending on the workpiece. Common structural types of electromagnetic chucks include rectangular and circular configurations. Rectangular magnetic poles are arranged in either longitudinal or transverse patterns. Longitudinal arrangement of rectangular magnetic poles is suitable for securing larger workpieces, while transverse arrangement is suitable for securing smaller workpieces. Circular chucks are suitable for securing ring-shaped workpieces or workpieces with complex geometries. The main characteristics of standard electromagnetic chucks are: magnetic flux lines are evenly distributed across the chuck surface, magnetic attraction cannot be concentrated, and the magnetic force per unit area is relatively low; the direction of the magnetic force is perpendicular to the chuck surface and difficult to alter, generating only one type of magnetic force for workpieces with the same contact area; the point of application of the magnetic force is limited to the contact surface between the workpiece and the chuck and cannot be freely adjusted. Therefore, disadvantages during machining include low positioning accuracy, insufficient clamping force, narrow scope of application, and low production efficiency.

JOKARI 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; generally, it needs to be tilted by 10-15°. 3) Do not "quench" (suddenly cool) a heated dressing tool. During dry dressing, maintain sufficient interval time between two dressings to allow the heated dressing tool to cool down. 4) Do not assume the grinding wheel surface is ideally flat. At the start of dressing, locate the high points of the grinding wheel and perform dressing. 5) If possible, the amount of material removed from the grinding wheel each time should not exceed 0.001 inches on the radius. 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 the dressing tool should not stay in one position for too long. 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 select excessive removal amounts and too fast lateral feed rates during rough dressing, and then select small removal amounts and slow lateral feed rates during fine dressing. This will quickly damage the diamond dressing tool. If possible, it is recommended to select the same lateral feed rate for both rough and fine dressing.
