Insize 3 Wire For outside micrometers with spindle Diameter 6.50 mm, 7382

The "Insize 3 Wire For outside micrometers with spindle Diameter 6.50 mm, 7382" is a specific set of three wires used in conjunction with outside micrometers manufactured by Insize. Here's more detailed information: Brand and Model: "Insize" is the brand, and "7382" is the model number assigned to this particular set of three wires. Three-Wire Measurement Method: The three-wire method is a technique used with outside micrometers to measure the diameter of cylindrical objects accurately. It involves placing three precision wires of known diameter across the micrometer's anvil and spindle, and then adjusting the micrometer until it gently touches the wires. The micrometer reading is then adjusted to account for the size of the wires, providing an accurate measurement of the object's diameter. Spindle Diameter: The specification "spindle Diameter 6.50 mm" indicates that these wires are designed to be used with outside micrometers that have a spindle diameter of 6.50 mm. The spindle diameter is the diameter of the cylindrical measuring surface of the micrometer that comes into contact with the object being measured.
