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

Overview

The WEIYEE MP-1DS Single-Disc Polishing and Grinding Machine is a compact, benchtop-mounted specimen preparation system engineered for precision surface conditioning of metallic, ceramic, and composite materials in metallurgical, materials science, and quality control laboratories. It operates on the principle of controlled mechanical abrasion—using rotational motion between a rotating abrasive disc and a manually or fixture-mounted sample—to achieve consistent planarization, coarse grinding, intermediate lapping, and fine polishing stages. Designed for single-specimen processing workflows, the MP-1DS supports standardized metallographic preparation protocols aligned with ASTM E3, ISO 13067, and EN 10365. Its robust cast-aluminum base, sealed motor housing, and integrated coolant channeling system ensure operational stability and thermal management during extended cycles.

Key Features

• Bidirectional rotation capability enables optimized material removal and reduced edge rounding—particularly beneficial for anisotropic alloys and brittle-phase composites.
• Continuously variable speed control (50–1500 rpm) permits precise matching of rotational velocity to abrasive type (e.g., SiC paper, diamond suspension, alumina slurry) and material hardness, supporting both aggressive stock removal and sub-micron finish refinement.
• 203 mm (8-inch) precision-ground stainless-steel platen ensures uniform surface flatness (< ±0.02 mm TIR) and long-term dimensional stability under load.
• Integrated digital speed display with real-time feedback provides repeatable parameter documentation essential for GLP-compliant reporting and inter-laboratory method transfer.
• Modular design allows rapid disc changeover and compatibility with industry-standard backing plates, adhesive discs, and quick-release polishing cloths (e.g., velvet, napped synthetic, or woven polyester).
• Front-accessible coolant inlet and radial groove pattern on the platen facilitate even fluid distribution and efficient swarf evacuation—minimizing heat accumulation and preventing specimen burn-in.

Sample Compatibility & Compliance

The MP-1DS accommodates specimens up to 40 mm in diameter (or rectangular equivalents ≤ 35 × 45 mm) when mounted in standard metallographic holders (e.g., cold-mounting phenolic or epoxy resins). It is routinely employed for preparing cross-sections of weldments, heat-treated steels, sintered carbides, semiconductor substrates, and geological thin sections. All mechanical and electrical components comply with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards. The unit meets CE marking requirements for laboratory equipment under the Low Voltage Directive (2014/35/EU) and Electromagnetic Compatibility Directive (2014/30/EU). Optional documentation packages support IQ/OQ validation per ISO/IEC 17025 and internal GMP audit readiness.

Software & Data Management

While the MP-1DS operates as a stand-alone analog-digital hybrid instrument (no embedded OS), its speed controller incorporates non-volatile memory that retains last-used parameters across power cycles—a feature critical for routine QC labs performing shift-based replicates. For traceability, users may log operating conditions (speed, duration, disc type, coolant flow rate) manually into LIMS-compatible templates or integrate the machine into broader lab automation via optional RS-485 serial output (available upon request). All calibration records, maintenance logs, and procedural SOPs align with FDA 21 CFR Part 11 expectations for electronic record integrity when paired with validated documentation systems.

Applications

• Preparation of optical microscopy specimens for grain structure analysis, inclusion rating (ASTM E45), and phase identification.
• Surface conditioning prior to microhardness testing (Vickers, Knoop) to eliminate relief artifacts and ensure accurate indenter penetration.
• Final polishing of TEM foil pre-thinning sites to reduce amorphous layer thickness prior to ion milling.
• Routine QA/QC of additive-manufactured parts where layer bonding integrity and porosity assessment require artifact-free interfaces.
• Research-scale sample prep for XRD texture analysis, where crystallographic orientation preservation demands minimal subsurface deformation.

FAQ

Is the MP-1DS suitable for automated mounting or only manual operation?
The MP-1DS is designed for manual specimen handling; it does not include auto-feed, force-controlled loading, or robotic integration. Specimens must be held either by hand (with appropriate PPE) or secured in standard thermosetting or cold-mounting holders.
Can the machine accommodate diamond-impregnated grinding discs?
Yes—the 203 mm platen supports bonded diamond discs (electroplated or sintered) with standard M6 or 1/4″-20 threaded backing plates, provided total disc assembly weight remains within 1.8 kg.
What safety certifications does the unit carry?
It carries CE marking per applicable EU directives and conforms to GB/T 20937-2018 (Chinese national standard for grinding/polishing equipment safety), including emergency stop functionality, splash-resistant enclosure, and thermal cut-off protection.
Is coolant flow rate adjustable?
Coolant delivery is manually regulated via a needle valve at the inlet port; no integrated flowmeter or closed-loop control is provided in the base configuration.
Does WEIYEE offer application support or method development assistance?
Yes—qualified applications engineers provide remote consultation for protocol optimization, including speed/duration/disc selection matrices tailored to specific alloy families or ceramic compositions.
