German RBMITALIA tools RBMITALIA models RBMITALIA prices

RBMITALIA 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 mixture containing 6.5-10%, undergoing 20 impacts without sparking or ignition.

RBMITALIA tool structure composition

The cross-sectional shape and distribution of the pole core vary depending on the workpiece. Common structures of electromagnetic chucks include rectangular and circular types. Rectangular magnetic poles are divided into longitudinal and horizontal arrangements. Longitudinal arrangement of rectangular magnetic poles is suitable for fixing larger workpieces; horizontal arrangement is suitable for fixing smaller workpieces. Circular chucks are suitable for fixing ring-shaped workpieces or workpieces with complex shapes. The main characteristics of ordinary electromagnetic chucks are: magnetic lines are evenly distributed on the surface of the magnetic disk, the electromagnetic attraction force cannot be concentrated, and the magnetic force per unit area is relatively small; the direction of the magnetic force is perpendicular to the chuck surface and is difficult to change, producing only one type of magnetic force for workpieces of the same contact area; the point of action of the magnetic force on the workpiece is limited to the contact surface between the workpiece and the chuck and cannot be changed arbitrarily. Therefore, there are disadvantages such as low positioning accuracy, insufficient clamping force, narrow scope of application, and low production efficiency during machining.

RBMITALIA 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 by 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 down. 4) Do not assume that the grinding wheel surface is ideally flat. At the start of dressing, locate the high points on 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 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 less 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 choose excessive removal amounts and fast lateral feed rates during rough dressing, and then choose 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 choose the same lateral feed rate for both rough and fine dressing.
