Description

The H-502 precision magnetic base stand is a high-stability alignment fixture dedicated to precision machining and inspection scenarios. Its dual-stem rigid structure delivers significantly better anti-vibration performance than single-arm models, eliminating measurement drift caused by machine vibration during high-precision grinding and finishing. The integrated micro fine adjustment system enables micron-level positioning without repeated stem adjustment, fully meeting strict accuracy requirements for precision mold, aerospace and automotive component inspection.

60kg/80kg Dual Specification V-Groove Magnetic Base

Two holding force options to match different working conditions: 60kg standard model for light precision inspection, 80kg heavy-duty model for high-vibration machining environments. Constructed from Q235 steel with built-in high-performance ferrite magnets, featuring a bottom V-groove for stable adsorption on both flat worktables and cylindrical surfaces such as spindles, guide rails and shaft parts. One-key on/off switch enables quick repositioning without external power.
Dual Rigid Stem Structure For Superior Stability

Adopts a dual-stem support design: 176mm long main stem with 12mm diameter, paired with 150mm long assistant stem with 10mm diameter. The double-column structure effectively eliminates arm sag and shaking, maintaining stable indicator position during long-hour continuous measurement, ensuring repeatable and reliable inspection data.
Independent Micro Fine Adjustment Mechanism

Precision fine adjustment knob at the clamping end delivers micron-level positioning accuracy. After rough locking of the stem assembly, operators can fine-tune the measuring head position smoothly by rotating the adjustment knob, avoiding positioning errors from repeated stem movement and greatly improving efficiency for batch workpiece inspection.
Universal Compatibility With Dovetail & 8mm Clamp

Industry-standard dual-compatible mounting: standard φ8mm (3/8" optional) clamp hole for conventional dial indicators and digital gauges, plus dovetail mount compatibility for professional lever test indicators. It works with all indicators with or without back lug, covering 99% of mainstream measuring instruments on the market.
Additional Threaded Mounting Holes For Flexible Installation

Reserved M8×1.25mm threaded holes on the base support permanent bolted installation in fixed inspection stations, in addition to magnetic adsorption, expanding application scenarios for production line and laboratory fixed measurement positions.
Retail-Oriented Packaging & Global Shipping

Each unit is packed in an independent shockproof export carton, supplied with full English operation manual and specification sheet. Standardized retail packaging is suitable for international express delivery, with clear packing dimensions and weight data for fast customs clearance.
