PCD Diamond Grinding Shoes For Epoxy Removal

PCD (Polycrystalline Diamond) Grinding Shoes are specialized, high-end abrasive tools designed for removing floor coatings. Featuring polycrystalline diamond composite segments as their primary cutting edges, they strip away thick coatings through scraping and fracturing actions. These tools effectively resolve common issues encountered when grinding epoxy with standard metal-bond segments-such as debris adhesion, clogging, low efficiency, and rapid wear-making them essential consumables for old floor renovation and coating removal projects.

A typical PCD grinding shoe for epoxy removal consists of two main components:
1 Steel Base:

Stamped or cast from Q235 or alloy steel, this serves as the structural foundation for the grinding tool. It features either pre-configured standard quick-change connections (such as Redi Lock, HTC, or Lavina systems) or pre-drilled bolt holes, and the surface is typically treated with anti-rust paint.

2 PCD Cutting Units:

These are the core working components, consisting of industrial-grade Polycrystalline Diamond (PCD) segments securely brazed onto the base using high-frequency induction brazing. Some models incorporate TCT (tungsten carbide) depth-limiting teeth to control the cutting depth and prevent excessive gouging of the concrete substrate.

Tips:

Sometimes we also add metal-bonded diamond grinding segments to improve grinding quality.

Classification by Connection Standard: Key Selection Criteria for Procurement
Fully compatible with standard grinding shoe connection systems; requires matching with the grinder's grinding disc:

• Redi Lock (Quick-change): Most widely available on the market; compatible with Husqvarna and most domestic general-purpose grinders; offers the best cost-performance ratio.
• HTC (Quick-change): Compatible with Swedish HTC heavy-duty grinders; features strong locking force; suitable for heavy-duty, large-area applications.
• Lavina (Quick-change): Compatible with US-made Lavina grinders; utilizes a twist-lock mechanism for maximum tool-changing efficiency.
• Bolt-on: Compatible with older terrazzo machines and standard grinding discs; low procurement cost, though tool replacement is relatively cumbersome.

HuiceTools company supplies PCD grinding shoes with different interface models that are compatible with various floor polishing machines. The above pictures are only examples. For more models and specifications, please contact our customer service personnel.

1. PCD Material: Industrial-grade Polycrystalline Diamond (PCD) composite; standard diamond layer thickness ranges from 1.6 mm to 3.2 mm.
2. Tooth Configuration: Available in single, double, triple, and five-tooth versions; the double-tooth configuration is the market standard, balancing efficiency with operational stability.
3. Coating Thickness Compatibility: Thin-coating version (0.5–1 mm), standard version (1–3 mm), and heavy-duty version (3–5 mm).
4. Equipment Compatibility: Compatible with floor grinders ranging from 70 kg to 600 kg; heavy-duty versions are recommended for use with machines weighing over 200 kg.
5. Operational Compatibility: Most models support both wet and dry grinding; wet grinding effectively lowers temperatures and facilitates debris removal, extending PCD service life by over 30%.
6. Connection Tolerances: Standard quick-change models feature dimensional tolerances controlled within ±0.2 mm, ensuring smooth insertion/removal and secure locking.

Incorporating PCD (Polycrystalline Diamond) grinding segments (or shoes) into the workflow for renovating old floors and treating coated surfaces is a standard, high-efficiency solution in the global flooring industry. It addresses the critical pain point where conventional metal-bond diamond segments fail to effectively process resin-based coatings, thereby comprehensively boosting project profitability across four dimensions: construction efficiency, total cost, service scope, and workflow continuity.

1. Thoroughly resolving the common industry issue of "clogging/glazing failure" associated with standard grinding segments
This is the primary reason for adopting PCD segments and addresses an inherent flaw in conventional diamond segments.

Standard metal-bond segments are sintered from metal powder and diamond particles, resulting in a matrix with microscopic pores. When grinding resin-based coatings-such as epoxy, polyurethane, or adhesives-the heat generated by friction causes the resin to melt. This molten material rapidly clogs the matrix pores and encapsulates the diamond particles, eventually forming a smooth, glazed surface. This leads to slippage, a failure to remove material, and a "clogging" effect where the tool becomes increasingly dull; consequently, work must be frequently interrupted to re-sharpen the tool with a dressing stone, resulting in extremely low efficiency.

In contrast, PCD (Polycrystalline Diamond) consists of a dense, monolithic diamond composite insert. Its surface is non-porous and structurally compact, preventing molten resin or adhesive from adhering or clogging the tool. The cutting edge remains sharp throughout the process, fundamentally eliminating the clogging issue and enabling continuous, stable operation.

II. Multi-fold increase in removal efficiency and significant reduction in project duration
PCD grinding segments utilize a "scraping and peeling" cutting action-as opposed to the "abrasive grinding" method of standard segments-resulting in an exponential boost in removal efficiency:

• When processing standard 1–2 mm epoxy flooring: Standard 16# metal grinding segments achieve an efficiency of approximately 1–2 m²/hour, whereas PCD segments reach 5–10 m²/hour-a 3- to 5-fold increase.
• When processing coatings thicker than 3 mm (such as heavy-duty epoxy, self-leveling compounds, or asphalt): Standard segments are largely ineffective and struggle to remove the material even with repeated passes; PCD segments, however, can completely strip the coating in a single pass, offering an efficiency advantage of more than tenfold.

For flooring contractors, the project schedule directly dictates labor costs and operational turnover. PCD segments are therefore a crucial tool for ensuring timely delivery, particularly for projects with tight deadlines, such as commercial flooring installations or work in shopping malls and industrial facilities.
