Overview
The SHT0193 Automatic Coil Winding Machine is a precision-engineered auxiliary device designed exclusively for the preparation of standardized copper wire coils used in Rotating Bomb Oxidation Test (RBOT) systems. It supports rigorous compliance with SH/T 0193–2008, the Chinese national standard for determining the oxidation stability of lubricating oils via the rotating oxygen bomb method. The machine replicates the geometric and dimensional specifications required for catalytic coil fabrication—critical for achieving reproducible induction period measurements under pressurized oxygen environments. Unlike manual winding methods prone to tension inconsistency and diameter variation, this automated system ensures uniform coil geometry, consistent wire pitch, and precise loop count—all essential parameters influencing thermal and oxidative response kinetics during RBOT testing. Its operation is grounded in electromechanical synchronization between motor-driven spool rotation and linear traverse feed, enabling deterministic coil formation without operator-dependent variability.
Key Features
- Fully automated winding cycle with programmable coil diameter control (44–48 mm range), ensuring strict adherence to SH/T 0193–2008 and ASTM D2272 geometric tolerances
- Dual-axis motion control system: stepper-motor-driven mandrel rotation coupled with synchronized linear carriage movement for repeatable pitch accuracy
- Integrated tension monitoring and adaptive braking to maintain constant wire elongation during winding—minimizing spring-back effects post-removal
- Quick-change mandrel interface compatible with standard 1.6 mm diameter copper wire (ASTM B188 specification) used in RBOT catalytic assemblies
- Front-panel digital interface with preset programs for common coil configurations (e.g., 10-turn, 12-turn, 15-turn); supports user-defined parameter storage
- Electrical safety compliance: 230 V AC, 50 Hz input; CE-marked power supply with overcurrent and thermal cutoff protection
Sample Compatibility & Compliance
The SHT0193 winding machine produces coils intended solely for use in RBOT analyzers operating per SH/T 0193–2008, ASTM D2272 (Standard Test Method for Oxidation Stability of Turbine Oils by Rotating Bomb), ASTM D4742 (Oxidation Stability of Engine Oils by RBOT), and ASTM D2112 (Oxidation Stability of Hydraulic Fluids). Coils are fabricated from electrolytic tough pitch (ETP) copper wire meeting ASTM B188 requirements, with surface oxide layer controlled to avoid catalytic interference. Each wound coil undergoes visual inspection and caliper verification against the 44–48 mm outer diameter tolerance band prior to deployment. The device itself does not perform analytical measurements but serves as a GLP-aligned sample preparation tool—its operational logs (cycle count, date/time stamp, operator ID) can be exported for audit trails in regulated laboratories.
Software & Data Management
The machine operates via embedded firmware with no external PC dependency. Configuration data—including coil turn count, mandrel speed (RPM), traverse rate (mm/rev), and dwell time—are stored in non-volatile memory and accessible through a 4-digit LED display and membrane keypad. All operational events (start/stop, error codes, maintenance alerts) are timestamped and retained for ≥1,000 cycles. While the unit lacks native network connectivity or USB export, its internal log structure conforms to minimum metadata requirements for FDA 21 CFR Part 11–aligned environments when integrated into broader laboratory information management systems (LIMS) via serial output (RS-232 optional module available upon request). Audit-ready calibration records and performance qualification (PQ) protocols are provided with initial installation.
Applications
- Preparation of catalytic copper coils for RBOT analysis of turbine oils, hydraulic fluids, and engine lubricants in QC/QA labs
- Supporting R&D studies on antioxidant package efficacy where coil-to-coil consistency directly impacts induction period repeatability
- Enabling multi-laboratory round-robin testing under ISO/IEC 17025 accreditation frameworks by eliminating inter-operator winding variability
- Facilitating compliance with OEM specifications requiring traceable coil geometry documentation (e.g., GEK 32568, Siemens TLV 9013)
- Integration into automated RBOT workflows where coil fabrication is sequenced upstream of bomb loading and temperature ramping
FAQ
What standards does the SHT0193 winding machine comply with?
It supports coil production compliant with SH/T 0193–2008, ASTM D2272, ASTM D4742, and ASTM D2112.
Can the machine wind coils with diameters outside the 44–48 mm range?
No—mechanical design and firmware validation are limited to the 44–48 mm specification mandated by referenced standards.
Is the device suitable for winding materials other than copper wire?
It is calibrated and validated exclusively for 1.6 mm diameter ETP copper wire per ASTM B188; alternative materials require full requalification.
Does the unit include validation documentation for GMP environments?
Yes—factory-issued IQ/OQ documentation, traceable calibration certificates, and PQ test scripts are supplied with each unit.
What maintenance is required for long-term operational reliability?
Quarterly inspection of mandrel bearings, monthly cleaning of wire guide channels, and annual verification of stepper motor step accuracy using optical encoder feedback.
