2009-5-31 Hollow sphere structures can be cut either with a pure water jet or an abrasive. The cut measuring an approximate width of 0.5 mm–1 mm, depending on whether an abrasive is used or not. For example, a material thickness of 8 mm had an approximate cut-width of 0.2 mm, where as a material density of 22 mm approximately 1 mm. Wire cut EDM. The width of a EDM cut is between 0.25 mm

Read More2016-10-14 So, the price of a sphere reflects the price of two hemispheres. Additionally, manufacturers create piezoelectric spheres by electrically wiring and then bonding together hemispheres. This assembly labour required to produce a sphere adds to the cost. Finally, machining the hemispheres themselves is a complicated and time consuming process.
