OUTSIDE MICROMETER INSTRUMENTS, 0.01 mm

Product Details

The Baker micrometer, a marvel of precision engineering, is a vital tool in the world of metrology and measurement. Renowned for its exceptional accuracy and ease of use, this device is a favorite among machinists, engineers, and quality control professionals for a wide range of applications. In this comprehensive description, we will explore the Baker micrometer, its design, functions, applications, and its indispensable role in achieving highly accurate measurements. The Design and Components: The Baker micrometer is a type of outside micrometer, designed for measuring the external dimensions of objects with great precision. It typically consists of several key components: Frame: The frame of the micrometer provides structural support and houses the other components. It includes a stationary anvil and a moveable spindle. Anvil: The stationary anvil is one of the contact points of the micrometer. It serves as the reference point against which the object to be measured is placed. Spindle: The spindle is the moveable part of the micrometer. It comes into contact with the object being measured and can be advanced or retracted using the thimble. Thimble: The thimble is a rotating collar on the micrometer, which allows the user to control the movement of the spindle. It is typically graduated with a scale for reading measurements. Sleeve: The sleeve holds the thimble in place and provides a reference point for zeroing the micrometer. Measuring Faces: The measuring faces of the anvil and spindle are made from hardened steel, ensuring durability and accuracy. Locking Mechanism: Some Baker micrometers feature a locking mechanism to secure the spindle in place during measurement. Operation: Using a Baker micrometer requires precision and care: Zeroing the Micrometer: Ensure that the micrometer is zeroed, meaning that the anvil and spindle faces are in contact but without excessive pressure. To zero, close the micrometer until the faces just touch, and then set the thimble to zero. Measurement: Open the micrometer and place the object to be measured between the anvil and spindle. Slowly close the micrometer by rotating the thimble until you feel a slight resistance. Ensure the object is held firmly but not overly compressed. Reading the Measurement: Read the measurement from the scale on the thimble and sleeve. The value on the sleeve represents millimeters or inches, and the thimble scale provides additional readings in increments of the smallest division. Recording the Measurement: Record the measurement, including any additional readings from the thimble, to the desired level of precision.
