How to select diamond segment for different scenarios and different drilling objects?
Diamond segment is an important part of diamond drill bit, which also accounts for the largest proportion of cost. Composed of metal powder and diamond particles. For different drilling objects, diamond segment has different formulations and sintering processes. Generally divided into mixing - cold pressing - mold - hot pressing - mold removal 5 steps to complete.
Important parameters of diamond segment:
The height under 16mm in diameter is 9mm
The height of the diameter above 16mm is 10mm
The length under 28mm in diameter is 22mm
The diameter above 28mm is 24mm
The thickness up to 16mm in diameter is 3mm
The diameter of 18-26mm is 3.5mm thick
The diameter is 28-56mm and the thickness is 3.8mm
The diameter is 63-127mm and the thickness is 4mm
A diameter of 132-152mm is 4.2mm thick
The diameter of 160-180mm is 4.5mm thick
The thickness above 200 is 5mm
The shape of high-frequency welding diamond segment produced by Tongling Changjiang Diamond includes flat segment , turbo segment, roof segment, crown segment, dot segment, mesh segment, etc. The shape of laser welding diamond segment includes flat segment and turbo segment. Each shape of the diamond segment has its own characteristics, and can be selected according to its characteristics.
⨠Flat segment:Durable
⨠Turbo segment:Fast water and chip removal
⨠Crown segment:Better sharpening of new core bits
⨠Dot Segment:Dot design is more suitable for cutting holes in uneven structures
⨠ Roof Segment:Better for newcomer openings
According to the characteristics corresponding to the shape of the diamond segment above, and combined with the drilling objects such as reinforced concrete, brick wall, asphalt or rock, the appropriate diamond segment are selected and welded on the drill core bit Bbarrel. There are high-frequency welding and laser welding to choose from. High-frequency welding can support welding of all diamond segment types, while laser welding only supports welding of flat segment and turbo segment types.
