Ceramic toilets are core products in the sanitary ware industry. After slip casting molding, ceramic toilet blanks commonly produce flashes, burrs and mold joint protrusions on edges and joint surfaces, along with residual particle impurities. The quality of toilet blank surface grinding directly determines the subsequent glazing effect. Unremoved burrs and flashes will cause glaze defects after firing, seriously affecting the appearance quality and finished grade of ceramic toilets. As brittle special-shaped curved workpieces, ceramic toilet blanks feature complex cavities and arc structures, bringing great difficulties to precision ceramic toilet grinding.
Traditional ceramic blank processing mainly relies on manual grinding with handheld tools. Toilet blanks are equipped with numerous curved surfaces and corner transitions, making uniform manual finishing almost impossible. Workers frequently face missing grinding issues or cause edge chipping and blank cracking due to excessive force, resulting in poor product consistency and high scrap rates. In addition, hard ceramic dust generated during processing creates harsh workshop environments, accompanied by high labor intensity, labor shortages and rising labor costs. Manual processing can no longer meet the large-scale and standardized production requirements of modern sanitary ware enterprises.
To solve the industry pain points of sanitary ceramic blank processing, we have independently developed the fully automatic toilet blank surface grinding workstation. This professional grinding workstation achieves intelligent unmanned trimming and blank grinding for ceramic toilet blanks, providing qualified blank workpieces for subsequent glazing processes.
Equipped with an industrial robot, floating force-control grinding spindle and professional grinding head, the workstation realizes high-precision robot grinding for complex ceramic workpieces. After accurate workpiece positioning and clamping, the robot intelligently fits the complex curved contour of toilet blanks. The advanced force control system adaptively responds to radian changes of ceramic bodies, precisely removing mold flashes, casting burrs and surface protrusions. It effectively avoids edge chipping and cracking, thoroughly protecting fragile ceramic blanks while completing high-standard finishing.
The dynamic real-time pressure adjustment of the force control unit completely eliminates over-grinding damage risks. The customized fixture tooling is compatible with toilet blanks of multiple specifications, supporting fast product switching and simple commissioning. Equipped with a professional dust removal and protection structure, the workstation controls ceramic dust diffusion, reduces manual contact with high-dust working areas, and significantly improves grinding efficiency and blank yield.
This intelligent grinding solution reduces sanitary ware enterprises’ reliance on skilled grinding technicians, stabilizes ceramic blank finishing quality and minimizes rework and scrap loss. It provides a reliable, efficient and standardized intelligent processing scheme for mass production and precision finishing of ceramic toilet blanks.
