Technical Overview
Equipment Detail
⚙ Machine Tool Characteristics
➤
High-Precision Spindle Structure: The guide wheel shaft uses a double-row roller shaft structure, sealed with grease for maintenance-free operation. Both grinding and guide wheel shafts adopt double support structures to ensure sufficient rigidity for mass production.
➤
Vibration Reduction: The drive motor of the grinding wheel is strategically located in the rear side to minimize operational vibration.
➤
Stepless Speed Control: The guide wheel is driven by a worm and gear system, allowing for uniform force bearing and stepless variable speed regulation.
➤
Advanced Three-Layer Platform: Features a cone adjustment turntable (superior), feeding guide rail (middle), and guide wheel platform rail (inferior). The rails are wide, thick, chromium-plated, and plastic-stuck for wear resistance and vibration absorption.
➤
Micro-Advancing Precision: Driven by a combined ball screw and worm gear system to ensure high-precision feeding.
