MWD Precision Resolver Positioning Post is a critical functional part for MWD systems. MH has worked on such functional parts of MWD systems for world leading customers for more than 20 years.

Product Introduction

MWD Precision Resolver Positioning Post is the key MWD component, its core function is to provide "baseline positioning + rotary guidance" for the MWD resolver:

√ Resolver Baseline Positioning

√ Rotary Guidance to Prevent Offset

√ Signal Accuracy Guarantee: High geometric tolerances ensure interference-free electromagnetic signal transmission from the resolver, accurately outputting measurement data such as well inclination and azimuth.

High Geometric Tolerance Machining Key Challenges

√ Micrometer-level dimensional control is challenging, with an outer diameter tolerance of only 0.001 inches (≈25μm).

√ Guaranteeing groove symmetry and angular accuracy is difficult; the groove width accuracy (±0.003) must be strictly symmetrical to the outer circle (≤0.02mm), and the angular surface must be perpendicular to the reference plane.

√ Multi-feature geometrical relationships are challenging; the outer circle, groove, and fillet must maintain multi-dimensional geometrical relationships in terms of coaxiality, symmetry, and contour.
