17. Gang Drilling

18. Deep Hole Drilling
a penetration of over 750 millimetres (30 in), without total destruction of the original component.

21. Operations in drilling machine

23. Abrasives
Abrasive is the material employed for sharpening, grinding and polishing operations.

24. Quartz abrasive corundum abrasive
Quartz is a chemical compound consisting of one part silicon and two parts oxygen. It is silicon dioxide (SiO2).
It is the most abundant mineral found at Earth's surface and its unique properties make it one of the most useful natural substances.

26. Epoxy Resin Synthetic Resin Vitrified
The raw materials of bonds are clay, feldspar, and glass.
Fired at a temperature about 1200℃.
Strong abrasives holding strength and high rigidity.
Applicable to a wide variety of work materials such as carbon steels and alloy steels.
Very suitable for precision grinding.
■Resinoid
The raw materials of bonds are synthetic resin like phenolic resin.
Cured at a temperature about 200℃.
Due to its elasticity, resin bonded products provide soft cutting action in precision grinding, such as disc grinding, centerless grinding, and roll grinding.
Due to its strength and impact resistance, resin bonded products are used for rough grinding applications, such as high pressure grinding, cut-off, and deburring.
■Rubber
It's made with rubber as a bond, and the rubber wheel is used as the regulating wheels for centerless grinding.
■Epoxy
Due to its property of epoxy bond, epoxy bond products are suitable for grinding unhardened steels on double spindle disc grinder and provide high metal removal rate without burns.
