findmall 5C Vertical Horizontal Collet Spin Index Fixture Milling Fit for Milling Machine

findmall 5C Vertical Horizontal Collet Spin Index Fixture Milling Fit for Milling Machine Specification: Spindle thread: 2-1/4 -8TPISpindle accuracy: 0.0004" TIRDividing spindle concentricity: 0.0004"Features:Indexing system: 24 accuracy ground indexing positions, single lever operation for quick locking, ratchet-assisted indexing, improving batch processing efficiency. Strict tolerance control: From center hole concentricity (0.0008 inches) to spindle parallelism (0.0008 inches), each parameter is strictly calibrated to ensure the overall coordination accuracy of the equipment.Compatibility: Standard 5C chuck, compatible with a variety of workpiece fixtures, seamlessly integrated into lathes, milling machines, and testing platforms.

• Spindle thread specification: 2-1/4-8TPI, quenched and ground, with a accuracy of 0.0004 inches TIR, ensuring long-term durability and stability.
• 24 accuracy-ground indexing positions on the indexing disc, paired with a 0.0004-inch concentricity indexing spindle, ensure accurate repeatability, good for high-accuracy machining.
• Center hole concentricity (0.0008 inches), spindle parallelism (0.0008 inches), and base verticality (0.0008 inches) ensure overall assembly accuracy.
• The single-lever indexing mechanism with a front ratchet for quick indexing and 5C chuck compatibility significantly improves work efficiency.
• The hardened threaded spindle is not easy to wear, with a lateral offset of only 0.0008 inches in the center groove, making it suitable for accuracy lathes, milling machines, and testing equipment.
