JY52-90B JIYAN 52mm Double-Face Zero-Point Block

The JY52-90B is a JIYAN 52 mm zero-point block, built for CNC machining centres, 4th/5th-axis setups and automated production lines that need repeatable, seconds-fast workpiece changes. It locates and clamps through the JYAN 52 mm zero-point interface with a documented repeatability of 0.005 mm, eliminating re-indication between stations and slashing changeover time.

Key Features

• 0.005 mm repeatability across every clamp/unclamp cycle for true drop-in accuracy.
• Quick-change via the 52 mm zero-point pull-stud interface — swap a pallet or fixture in seconds, no re-alignment.
• Hardened steel locating elements seated in an aluminium body for rigidity without excess mass.
• Works with self-centering vises, 3-jaw chucks and ER-collet fixtures that carry a 52 mm stud pattern.
• Doubles as a permanent machine-table datum — mount once, re-seat tooling and pallets against it all day.
• Bolt-down base with precision reference faces for fast, square installation.

Technical Specifications

Applications

• Permanent zero-point datum on machining-centre tables and 4th/5th-axis rotary tables.
• Multi-pallet cells where every pallet must return to the same reference.
• Bridge plates, risers and custom fixtures that need a common mounting origin.

Why Choose JIYAN

JIYAN designs and manufactures its zero-point system in-house — machining, heat treatment, grinding and inspection all happen under one roof. That vertical integration is why every pallet and block holds the same 0.005 mm repeatability batch after batch, and why we can supply complete kits (pallet + pull studs) ready to bolt down and run.
