INSIZE DIAL INDICATOR
An INSIZE dial indicator is a precision instrument used for measuring small distances and amplifying them for easier viewing, commonly found in machining and manufacturing. These indicators feature a jeweled bearing for smooth operation, a shockproof design for durability, and are supplied with accessories like limit pointers and a bezel clamp. Specifications vary by model, but common features include a range (e.g., 10mm), graduation (e.g., 0.01mm), and accuracy (e.g., 17µm).
Key features and specifications
- Jeweled bearing: Provides a smooth, low-friction movement for accurate readings.
- Shockproof: Many models are designed to withstand impact, making them more durable in demanding environments.
- Accessories: Often supplied with limit pointers to mark a tolerance range and a bezel clamp for easy attachment.
- Range/Graduation: These vary by model, but common metric examples include a 10mm range with 0.01mm graduations, and inch examples include a 1-inch range with 0.001-inch graduations.
- Accuracy/Hysteresis: Specific values depend on the model, such as an accuracy of 17µm and hysteresis of 3µm for some models.
- Back types: Models can feature a lug back, a flat back, or a combination of both.
How it’s used
- Machining: Used to ensure a workpiece is running true on a lathe by indicating any runout.
- Inspection: Employed to check for flatness, squareness, and other geometric features on a part.
- Setup: Helps align a piece of material in a chuck or other fixture
