          Diamond Processing

  

We have developed laser machines for every step of processing rough Diamonds, including Planning & Marking, Setting banding and Sawing Parameters, Sawing, 4P, 5P, Blocking. Our aim is to achieve minimum weight-loss, minimum breakage, optimum productivity and lowest possible maintenance.

 

Diamond processing technology shift

 

With the introduction of laser technology, conventional machines were replaced by advanced laser cutting machines. Manual planning and marking, and the conventional machines previously used for diamonds processing, were replaced with software-based, laser-equipped units. The latest-generation, laser-equipped diamond planning machine proved to be more precise and effective; once a rough diamond is placed in this machine, it creates a 3D image of it and then carries out the first step of planning (see right picture).

 

How laser diamond cutting works

 

First, the rough diamond is measured and an AI-assisted planning process then guides the user for optimal yield from the diamond. Then, it obtains a clear picture regarding the weight, shape, and clarity of the proposed polished diamond. Specialized software gives the operator options to select the shape of the diamond, depending on elimination of inclusions, and displays its market value onscreen. In the next step, the numbers of sides and percentage of sawing and banding are selected, enabling optimal safety and finalizing minimum weight loss. The operator clicks a button and the perfect laser sawing gets started. After completion of the above process, the next step is to cut the rough diamond according to the plan. Laser cutting machines are among the most preferred machines for this job, as these are compatible with former planning machines. These laser cutting machines take care of the sawing, shaping, blocking, and 4-in-1 process (a.k.a. 4P), and cut pre-planned rough diamonds (FIGURE 2). The final result is always appreciable compared to what one gets from the conventional method of diamond planning and cutting.

The notable features of laser-equipped diamond planning and cutting machines are:

  1. They are highly precise, accurate, and repeatable;

  2. They are great time-savers as a single planning machine, and up to five machines can be used in line to increase productivity;

  3. They reduce the requirement of scarcely available skilled manpower due to user-friendliness and easy operation;

  4. They reduce human errors to almost zero;

  5. They reduce overall material loss during cutting to 1% or less compared to 8% with conventional methods; and

  6. They are highly robust and require very low maintenance cost.

 

Diamond Processing Laser Machines
STST-MD series (planner)

Enthrall yourself with the power packed STST-MD planning machine. Made from high-grade materials and exemplary craftsmanship, the STST-MD is an exceptional blend of robust technology and compact design. It achieves the most precise measurement of rough stones with highest production in its class.
With a sleek scratch-resistant aluminum body, production speed of 78 stones/hour* and a splendid vision quality by color camera & five zone lighting, the new STST-MD reshapes the diamond planning experience to the next level.

 

 

With The colour camera and five zone lighting provides superior visual quality and makes inclusion detection effortless.
Stable and long-life laser source is utilized to make precise and clearly visible laser marking on the diamond. This makes sawing and
bruiting processes faster and more accurate. As an added advantage, STST-MD has superior marking patterns to choose from.

STST-MA (set banding and sawing parameters)
Manual setting of banding and sawing parameters consumes a significant amount of time and the chances of human errors are too high. STST-MA will set the banding and sawing parameters with high speed and accuracy. During this process, one need not stop the laser-sawing machine for setting of banding and sawing parameters, it keeps on running. This helps saves a good amount of time and chances of human error are minimised.

 

 

 

 

Work Flow

 

1. After the rough diamond passes the stages of planning and sticking, the diamond-under-processing is placed in STST-MA.

 

2. Similar to STST-MD, the STST-MA creates a 3D image of the rough stone. Starting line for the sawing process is calculated.

 

3. Percentage for sawing are finalised. Numbers of ides for banding are finalised. Sawing and branding lines giving maximum safety and minimum weight loss are finalised

 

4. STST-MA is compatible with our laser sawing machines STST-V, STST-LS9, STST-LS9E, STST-DSG and can send data to these machines

 

 

 

 

Features

  • User friendly software for STST-MA is exclusively designed to determine the best parameters for banding and sawing rough diamonds.

  • The entire workload of banding and sawing parameters setting is transferred from laser cutting machine to STST-MA, thus giving more time to laser cutting machine to increase productivity.

  • Entire process of setting banding and sawing parameters is done in rapid and precise manner by advanced algorithm software, leaving no chance for human error. This results in gaining safety assurance against breakage with minimum weight loss from a rough diamond.

  • A single STST-MA unit can be used for 2-4 laser cutting/sawing machines. This will reduce the manpower requirement.
    Saves time, increases productivity and gains a good reputation for your company on getting best yield from your diamonds
    High grade optics and advanced technology integrated in a single, compact scratch proof body.
