Ordered layout is an internal architecture
These technical references show regular surface exposure and profile variants. They support RFQ communication but do not replace process or cross-section evidence.
Pattern-positioned core-bit segments
Regular surface exposure can be consistent with ordered placement, but the production specification must also confirm the three-dimensional layout through the usable depth.
- Regular exposure pattern
- Curved core-bit segments
- Full-depth evidence required
Profile variants with regular diamond exposure
Profile notches and diamond positions are two different design layers. Approve the side geometry and the internal placement map separately.
- Profile variants
- Regular diamond exposure
- Two-axis approval
Placement vs Geometry: The Core Distinction
ARIX-type, pattern-positioned and ordered-array describe diamond placement inside the metal-bond matrix. They are not segment geometry. Segment geometry describes the visible body and working-face profile: flat, turbo, roof, Great Wall, dotted top, tapered wedge and other drawing-controlled shapes.
The two axes can be combined independently. A roof-profile segment may use random, uniform or ordered diamonds. An ordered-array segment may use a flat, roof or another approved profile. Keep profile and placement on separate RFQ lines.
1. Random Distribution
Diamonds are mixed into the metal powder without controlling individual coordinates. A well-controlled process can still produce a usable professional segment, but local clusters and gaps are more likely than with a deliberately managed distribution. Random placement is a manufacturing description, not automatically a quality verdict; bond matching and sample performance remain decisive.
2. Uniform Distribution
Uniform distribution controls the average concentration and dispersion through the mix. Each zone aims to receive a similar diamond population, while individual crystal coordinates remain unassigned. This is a practical architecture for many professional programs because it can deliver repeatable exposure without the added placement steps of an ordered array.
3. Ordered / Matrix-Positioned Array
Ordered placement controls planned diamond coordinates, layers or spacing before the segment is consolidated. The engineering objective is more even load sharing, predictable exposure and reduced diamond-free zones as the bond wears. Tyrolit's official TGD description similarly treats grain distribution, balanced load, cooling and self-sharpening as a connected system, not as a visible segment shape.
Do not publish a universal life or speed multiplier. The benefit changes with concrete aggregate, reinforcement, bond, grit, concentration, profile, segment width, water, RPM, torque and feed.
How to Verify the Layout
- Process evidence: placement method, layer plan and production controls.
- Section evidence: an approved layer map or cross-section showing depth and spacing—not only surface dots.
- Sample evidence: repeatable drilling speed, rebar transition behaviour and wear against the signed sample.
- Lot evidence: dimensions, bond identification and placement checks tied to the production batch.
A dotted or dimpled top by itself proves only a visible surface feature. It may be compatible with ordered placement, but it is not sufficient evidence of a three-dimensional array.
Ordered Placement Inside a Reinforced-Concrete System
Steel reinforcement adds ductile cutting, heat and impact to abrasive mineral removal. Ordered placement can help distribute load across available cutting points, but it cannot rescue a glazed bond, weak joint, poor water flow, excessive runout or the wrong machine settings. Hilti's coring systems actively coordinate speed, torque and water flow; Husqvarna requires low vibration and limits radial runout at the diamond segments. Field performance is a system result.
OEM Specification
Diamond core bit segment for wet reinforced-concrete drilling. Segment profile: drawing-controlled roof / flat / approved alternative. Diamond placement: controlled three-dimensional ordered array, specified separately from profile. State diamond grade direction, grit range, concentration target, bond direction and segment dimensions. Provide placement-process evidence plus an approved section or layer reference. Validate sample and production lot using drilling progress, rebar transition, segment wear and cost per accepted hole.
Send Zhonghuan the substrate, aggregate, reinforcement, diameter, depth, machine power, water condition and benchmark sample. We return the proposed placement architecture, profile, bond and sample plan for engineering confirmation.
