Tinna Rubber And Infrastructure Manager Interview Questions and Answers

Pitch of a micrometer refers to the distance moved by the spindle per revolution of the thimble.

• Pitch is typically engraved on the frame of the micrometer as the distance moved by the spindle for one complete revolution of the thimble.

• It is used to calculate the measurement resolution of the micrometer.

• For example, if the pitch is 0.5mm, then each division on the thimble corresponds to 0.01mm of movement of the spindle

Yes, it is possible to punch a hole with a diameter of 3mm in a sheet with a thickness of 4mm using a press tool.

• The hole diameter should be smaller than the sheet thickness to ensure successful punching.

• Consider the material of the sheet and the type of press tool being used for punching.

• Ensure proper alignment and clearance for the punching process to avoid any issues.

• Example: Using a hydraulic press with a sharp pun...read more

Pitch of a micrometer refers to the distance moved by the spindle per revolution of the thimble.

• Pitch is typically expressed in millimeters or inches per revolution.

• It is used to calculate the measurement resolution of the micrometer.

• For example, a micrometer with a pitch of 0.5mm will move 0.5mm for each full rotation of the thimble.

Yes, a sheet thickness of 4mm can be punched.

• The punching process involves using a tool to create a hole or cut in the material.

• The ability to punch a 4mm thick sheet will depend on the type of punching machine and the material being punched.

• For thicker sheets, a more powerful punching machine may be required.

• Examples of punching machines include turret punch presses and hydraulic punch presses.
