How to make a diamond segment?

2026-05-09

Step 1: Layered Dosing – Let Each Powder Layer “Do Its Own Job”

A high-performance segment often contains a working layer and a bonding layer (or an underlayer specially designed for laser welding). Under traditional methods, different powders tend to mix, leading to reduced bond strength or unstable cutting performance.

The machine employs the “Powder Separation Technique”. Before production starts, movable separators clearly divide the mold cavity into distinct zones – working layer powder and bonding layer powder each enter their designated positions without interfering with each other. Then, the “External Precision Dosing System” (cylindrical dosing units) independently weighs each powder layer. This means that no matter how many segments are produced, the weight and thickness of each layer remain highly consistent.

✅ Advantage: Eliminates layer thickness deviation and powder mixing issues. The segment structure is clearly layered, bonding layer density is uniform, laying a solid foundation for subsequent laser or high-frequency brazing.

Step 2: Ordered Diamond Placement – Let Every Diamond “Stand in the Right Position”

This is the core and most technologically advanced step in the entire production process. In traditional segments, diamond grits are randomly distributed in the metal powder matrix. During cutting, many diamonds do not actually participate in cutting and fall off prematurely.

The Arix machine uses the “Pinhole Suction Diamond Placement” technology. The operator customises a pin mould (4 pin moulds for the linear machine, 5 for the rotary disc machine) according to the required segment shape, size, and diamond concentration. The pinholes in the pin mould use vacuum suction to arrange the diamond grits in a designed ordered pattern, then precisely transfer them into the cavity where the working layer powder has already been laid. The whole process is fully automatic, with a diamond adsorption rate exceeding 98%.

✅ Advantage: Diamonds are arranged in a three-dimensional ordered pattern within the segment, so every grit participates in cutting without waste. Compared to random distribution, cutting speed and tool life are significantly improved.

Step 3: Multi-station Rotary Pressing – From “One by One” to “Continuous Production”

This step highlights the most distinctive structural advantage of the machine: the multi-station rotary disc design. The mould is fixed on a rotating disc and sequentially passes through various stations: powder filling, diamond placement, powder levelling, pre-pressing, final pressing, and demoulding. All operations are performed simultaneously at different stations – while one segment is being finally pressed, another is receiving diamonds, and another is being demoulded… The machine never has idle time.

Compared to traditional single-mould linear machines (where the next segment can only be produced after the previous one is finished), this “Moving Mold Cavity” method dramatically shortens the production cycle. For a multi-layer segment, a linear machine takes about 50 seconds to produce one 5‑layer segment, whereas the rotary disc machine takes only about 11 seconds for the same segment.

✅ Advantage: Production efficiency is increased several times. Daily output capacity is significantly improved, delivery times are shorter, and labour cost per piece is greatly reduced.

Step 4: Vision Inspection & Automated Collection – Traceable Quality with Minimal Manual Intervention

During production, the machine can be optionally equipped with an “Industrial Vision Inspection System”. Built‑in cameras and light sources capture real‑time images of the diamond placement in each layer, and the system automatically judges whether the adsorption rate meets the standard. All data can be stored and traced. If an anomaly occurs, the machine automatically stops and alarms. This is like giving every diamond a “physical check‑up”.

After pressing and demoulding, the “Automated Collection Station” automatically places the finished segments into a designated collection unit, eliminating manual handling and preparing them for downstream automation.

✅ Advantage: Vision inspection ensures product consistency. Automated collection reduces manual handling damage and supports quality traceability. Enterprises can confidently carry out large‑scale or small‑batch custom production.

Which Segments Can Be Produced?

Segments for granite, marble, and concrete saw blades
Segments for reinforced concrete cutting and drilling
Segments for asphalt and hard stone processing
Segments for railway and construction drilling tools
Multi‑layer segments with a laser‑bonding underlayer

The machine also supports diamond grit sizes ranging from 20/25 to 50/60 mesh, and can assist in designing ordered diamond patterns free of charge based on the customer’s existing segment diamond concentration.

Conclusion: Making Every Customer an Expert in Ordered Diamond Segments

The value of the Arix Diamond Multi‑station Rotary Disc Cold Press Machine does not lie in cold numbers. It lies in offering a clear, controllable, and highly efficient process that brings “ordered diamond segments” from the laboratory to real‑world mass production. From powder to finished part, every step is transparent, verifiable, and traceable.

If you are looking for a solution that can stably produce high‑quality segments while significantly improving efficiency and reducing labour dependence, this machine deserves your in‑depth attention.
