Manufacturing processes for silicon semiconductor
Silicon Ingot ⇒ Cropping(electroplated bandsaw) ⇒ Cylindrical / Flat Grinding Silicon Rod ⇒ Ingot Silicon (diamond wire) ⇒ Lapping (double side wheel/polishing pad) ⇒ Edge Grinding ⇒ Surface grinding ⇒ polishing⇒ wafer⇒ patterning ⇒ back grinding (vitrified / resin wheels) ⇒ dicing (dicing blades)⇒ chips ⇒ molding ⇒ packaging

Vitrified diamond wheels are used for cylindrical grinding and finishing carbide coated rollers, printing roll, ceramics, wear parts and others hard coated materials. At present, our Vitrified diamond wheel can reach up to 28 inch ( 720 mm) diameter.

vitrified diamond mounted points applications: tungsten carbide mold, die and jig for mechanical and electronics industry, ball nut grinding, precision profiles
Internal grinding/ ID grinding

Diamond wheels- vitrified/ ceramic bond are manufactured to create higher levels of porosity.
Moresuperhard Vitrified grinding wheels are an ideal choice for ball screw grinding, grinding of cast iron or steel parts such as injection nozzles, compressor blades and vanes, PCD and PCBN tool and insert grinding, plus OD grinding of automotive and aerospace industry parts.

vitrified diamond grinding wheels mainly used for sharpening circular saw blades of cemented carbide, high-speed steel, cermet, PCD and pcbn, cvd, mcd, and band saw, etc

Diamond and CBN (cubic boron nitride) internal grinding wheel produced by moresuperhard’s factory can achieve a small diameter of 1.5 mm, and the wear resistance is very good, and there is no need to frequently trim the outer circle. Batch processing of small holes of parts can ensure the consistency of roundness, perpendicularity and diameter tolerance accuracy, high temperature resistance during the grinding operation, and no burns on the workpiece and the grinding wheel.
Grease grinding fluid must be added during the grinding process To cool down and remove chips (tap water can not be added directly, tap water will carbonize the high-temperature grinding CBN raw materials), to avoid the large amount of metal scrap generated during the grinding process from squeezing the hole wall of the workpiece and blocking the pores on the surface of the cubic boron nitride grinding head .
