Description
HHIP 3906-4123 MT3 x 335mm Test/Alignment Mandrel is a precision tool designed for checking and aligning machine spindle axes. Crafted from high-grade tool steel, this mandrel is precision ground and heat treated to ensure maximum concentricity and reliable performance. It serves as a reference axis of rotation, allowing accurate verification of machine alignment between centers.
Features:
- Constructed from high-grade tool steel for durability and accuracy.
- Precision ground and heat treated for maximum concentricity.
- Represents a true axis of rotation for alignment checks.
- Can be mounted between centers to provide a straight-line reference.
- Total Indicator Reading (T.I.R.) is less than 5 microns per 6″.
- Ideal for checking machine spindle alignment and straightness of centers.
Benefits:
- Ensures precise alignment of machine spindles for accurate machining.
- High-quality steel construction guarantees long-term reliability.
- Enables easy verification of straightness and concentricity between centers.
- Reduces setup errors and improves machining accuracy.
