Grinding and Polishing Technology of Revolving Shaped Stone Railings

Abstract

The invention relates to a grinding and polishing technology for a rotary type specially-shaped stone handrail. The technology comprises steps as follows: step A, a specially-shaped stone handrail green body is prepared from stone after large surface cutting and engraving molding; step B, an engraving and grinding knife is driven by a motor to rotate to perform primary grinding and polishing on the specially-shaped stone handrail green body, the revolving speed of the motor is 18,000-24,000 rpm, and the engraving and grinding amount of the surface of the specially-shaped stone handrail green body is 1-2 cm; step C, according to the requirement for surface brightness of a finished product, secondary grinding and polishing is performed at least once, the specially-shaped stone handrail green body is machined to form a finished handrail product, and the fineness of an grinding material for secondary grinding and polishing is larger than or equal to 500 meshes. With the technical scheme, the engraving and grinding knife is directly used for performing primary grinding and polishing on the stone, for the stone requiring repeated grinding and polishing, first few preliminary grinding technologies can be reduced, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to a grinding and polishing process for a rotary special-shaped stone railing, which belongs to the field of stone processing. Background technique [0002] In the field of stone processing, stone processing mainly includes stone cutting and stone grinding and polishing. For example, the authorized announcement number CN 202278668 U, in the Chinese utility model patent titled "A Multi-functional Multi-head Cylindrical Stone Profiling Machine", discloses a multi-functional multi-head cylindrical stone profiling machine, a multi-functional multi-head cylindrical stone Stone profiling machine, which includes: a base; pillars, including front left pillars, front right pillars, rear left pillars and rear right pillars fixed on the base, the tops of the pillars are connected into a trapezoidal structure by four connecting beams; the workpiece The positioning device includes the upper and lower beams arranged between the front left and ...
