WEIYEE MP-1DC Single-Disc Polishing and Grinding Machine

Overview

The WEIYEE MP-1DC Single-Disc Polishing and Grinding Machine is an engineered solution for precise, reproducible specimen preparation in metallurgical, materials science, and quality control laboratories. Designed around the Couette-type rotational polishing principle—where controlled shear stress is applied between a rotating abrasive disc and a stationary or manually held specimen—the MP-1DC delivers consistent material removal and surface finish across diverse sample geometries. Its single-disc architecture simplifies operational workflow while maintaining full control over rotational dynamics, making it especially suitable for routine metallographic grinding, pre-polishing, and final polishing steps where process repeatability and operator safety are critical. The machine complies with IEC 61000-6-2 (EMC immunity) and IEC 61000-6-4 (EMC emission) standards, ensuring stable performance in shared laboratory environments.

Key Features

• Single 203 mm (8-inch) precision-machined aluminum alloy grinding/polishing disc with balanced dynamic load distribution and thermal stability up to 60 °C continuous operation
• Continuously variable speed control from 50 to 1500 rpm, independently adjustable for clockwise and counterclockwise rotation—enabling optimized material removal rates for soft alloys, hardened steels, ceramics, and composites
• Industrial-grade 7-inch capacitive touchscreen HMI with IP65-rated front panel, supporting multi-language interface (English, German, Spanish, Chinese), real-time speed monitoring, and user-defined preset profiles
• Integrated mechanical brake system with <1.5 s deceleration time and automatic rotor lock at standstill, reducing risk of accidental contact during sample loading/unloading
• Modular base design with anti-vibration rubber mounts and adjustable leveling feet, minimizing transmission of operational resonance to adjacent instrumentation
• Optional disc adapter kits available for mounting standard 203 mm consumable pads (e.g., MD-Piano, Struers DP-Spray compatible) and electroplated diamond discs (125–500 µm grit)

Sample Compatibility & Compliance

The MP-1DC accommodates specimens ranging from 10 mm to 50 mm in diameter (or rectangular equivalents up to 50 × 30 mm), including mounted and unmounted metallographic samples, geological thin sections, electronic packaging substrates, and polymer composites. It supports all common abrasive media—including silicon carbide papers (P80–P2500), alumina suspensions (0.05–3 µm), colloidal silica (20–30 nm), and diamond pastes (1–6 µm)—via standard disc backing plates. The unit meets ISO 13079:2014 (Metallographic specimen preparation — General principles) and aligns with ASTM E3-22 (Standard Guide for Preparation of Metallographic Specimens) for manual and semi-automated grinding/polishing workflows. Its electrical safety design conforms to GB/T 19001–2016 (equivalent to ISO 9001) and includes dual redundant thermal cutoffs in the motor winding and drive electronics.

Software & Data Management

While the MP-1DC operates as a standalone instrument without embedded data logging, its touchscreen controller retains up to 20 user-defined process recipes—including speed setpoints, rotation direction, dwell time per step, and motor torque limit thresholds—for rapid recall and audit-ready consistency. All parameter changes are timestamped and stored in non-volatile memory with GLP-compliant event logging (date/time, operator ID placeholder, mode change). Optional RS-485 Modbus RTU interface enables integration into centralized lab management systems (LIMS) for traceability in regulated environments (e.g., ISO/IEC 17025 accredited labs). Firmware updates are performed via USB 2.0 port using signed binary packages, supporting version rollback and cryptographic signature verification.

Applications

• Metallographic specimen preparation for optical and electron microscopy (SEM/TEM cross-section analysis)
• Surface planarization of sintered tungsten carbide, silicon nitride, and alumina ceramics prior to hardness testing (ASTM E384)
• Edge retention evaluation in coated tool steels using standardized grinding cycles
• Preparation of failure analysis samples from additive-manufactured aerospace components (Ti-6Al-4V, Inconel 718)
• Routine QC polishing of PCB laminates and semiconductor wafer edge bevels
• Geological thin section finishing for petrographic analysis under polarized light

FAQ

Is the MP-1DC compatible with automated sample holders or force-controlled polishing arms?
No—the MP-1DC is designed exclusively for manual specimen handling. For force-regulated or multi-step automated workflows, consider the WEIYEE MP-2AC dual-disc system with optional pneumatic load module.
Can the 203 mm disc be replaced with a smaller or larger diameter?
Disc diameter is fixed at 203 mm per mechanical design constraints; however, custom backing plates support 150 mm or 250 mm consumables upon engineering review and structural validation.
Does the unit include CE or UL certification documentation?
The MP-1DC carries CCC (China Compulsory Certification) and complies with EMC and LVD requirements per GB 4793.1–2019. CE marking is available upon request for EU-bound units with additional conformity assessment.
What maintenance intervals are recommended for long-term reliability?
Motor brush inspection every 1,200 operating hours; disc bearing lubrication every 6 months or 2,000 cycles; touchscreen calibration annually or after firmware update.
Is remote diagnostics or firmware update support available?
Yes—technical support provides secure remote access via TeamViewer QuickSupport (ISO 27001 compliant session protocol) for configuration troubleshooting and firmware deployment.
