Abstract
The utility model discloses a grinding flap disc, comprising a base disc and a grinding layer disposed on the base disc, the base disc is disposed on a positioning disc, the grinding layer comprises a plurality of common abrasive emery cloth blocks and cubic boron nitride or diamond emery cloth blocks, the common abrasive emery cloth blocks and the cubic boron nitride or diamond emery cloth blocks are in an alternative and stagger bonding to the base disc along the circumferential direction. The grinding flap disc is advantageous in that, since the cubic boron nitride or diamond emery cloth blocks are advantaged by high abrasive hardness and high strength when the blocks are combined into metal. Falling-off of abrasive particles and crack of emery cloth blocks can be effectively prevented, grinding temperature is greatly reduced, grinding efficiency, durability, process quality, and cost performance of the grinding flap disc are improved, and the difficult problem of grinding and processing of difficultly-processed metal and non-metal materials is solved. In addition, the grinding flap disc is also characterized by little dust and low noise during use, improving working environment, and effectively reducing harm upon human body.
Description
Technical field
The utility model belongs to the grinding tool technical field, particularly a kind of grinding page or leaf dish.
Background technology
At present, coated abrasive tool is widely used in field of machining, for example grinds the page or leaf dish, its structure stacked stickup emery cloth piece of order and forming on the matrix dish, be used for the grinding and polishing processing of metal and nonmetal parts, to reach the purpose that surface of the work has best bright finish and high gloss.Above-mentioned grinding page or leaf take inventory defective be: stick on easy delamination of emery cloth piece and be full of cracks on the matrix dish, abrasive hardness is low, be the easy threshing of resin bonding between abrasive material and the fabricbase, to the grinding efficiency of high rigidity difficult mill metal and nonmetallic materials low and heating burn workpiece, the surface of the work crudy is poor, the usability price ratio is low; In use dust is more simultaneously, and poor working environment has bigger harm to human body.
The utility model content
The purpose of this utility model provides the grinding page or leaf dish of a kind of grinding efficiency height, long service life.
For achieving the above object, the technical solution of the utility model is: a kind of grinding page or leaf dish, comprise matrix dish and the grinding layer that is arranged on the matrix dish, the matrix dish is located on the positioning disk, described grinding layer comprises polylith conventional abrasive material emery cloth piece and cubic boron nitride or boart boart cloth, along the circumferential direction alternately staggered stacked being bonded on the matrix dish of conventional abrasive material emery cloth piece and cubic boron nitride or boart boart cloth.
Described positioning disk is provided with fixedly circular hole.
Described cubic boron nitride or boart boart cloth comprise matrix and alternately are arranged with cubic boron nitride or adamantine flexible parent metal that flexible parent metal is attached to substrates by the heat resistant adhesive lamination.
Described cubic boron nitride or diamond are plants sand or point-like orderly being arranged on the flexible parent metal at interval entirely.
Compared with prior art, the utility model has the advantages that: the grinding layer that is provided with on the matrix dish comprises polylith conventional abrasive material emery cloth piece and cubic boron nitride or boart boart cloth, along the circumferential direction alternately staggered stacked being bonded on the matrix dish of conventional abrasive material emery cloth piece and cubic boron nitride or boart boart cloth, because the abrasive hardness height of cubic boron nitride or boart boart cloth, be combined into metal, the intensity height, can prevent effectively that abrasive particle from coming off and the be full of cracks of emery cloth piece, greatly reduce grinding temperature, improved the grinding efficiency that grinds the page or leaf dish, durability, crudy and cost performance, a difficult problem is processed in the polishing that has solved difficult-to-machine metal and nonmetallic materials.In addition, in use dust is few, noise is little, has improved working environment, effectively reduces the harm to human body.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view among Fig. 1;
Fig. 3 is the partial sectional view of Fig. 1 cubic boron nitride or boart boart cloth;
Fig. 4 is the vertical view of Fig. 3.
The specific embodiment
Grinding page or leaf dish as depicted in figs. 1 and 2, it comprises matrix dish 1 and the grinding layer that is arranged on the matrix dish 1, matrix dish 1 is installed on the positioning disk 2, grinding layer comprises polylith conventional abrasive material emery cloth piece 4 and cubic boron nitride or boart boart cloth 5, conventional abrasive material emery cloth piece 4 and cubic boron nitride or along the circumferential direction alternately staggered stacked the sticking on the matrix dish 1 of boart boart cloth 5, can effectively prevent delamination of emery cloth piece and be full of cracks, improved and ground the good and usability price ratio of grinding efficiency, durability, suface processing quality of page or leaf dish, and can reduce grinding temperature and processing cost; Simultaneously, in use dust is few, noise is little, has improved working environment greatly, effectively reduces the harm to human body.Intensity and positioning accuracy for the centre bore that improves novel grinding page or leaf dish are provided with fixedly circular hole 3 on positioning disk 2.
Cubic boron nitride as shown in Figure 3 and Figure 4 or boart boart cloth, it comprises matrix 51 and flexible parent metal 52, on flexible parent metal 52, be plant full sand or point-like orderly at interval be arranged with cubic boron nitride or diamond 53, cubic boron nitride or diamond 53 are attached to flexible parent metal 52 by electroforming process, the frivolous softness of emery cloth be can make, delamination and be full of cracks are difficult for during use.Flexible parent metal 52 overlays on matrix 51 by heat resistant adhesive layer 54.
Claims (4)
1. one kind is ground the page or leaf dish, comprise matrix dish and the grinding layer that is arranged on the matrix dish, the matrix dish is located on the positioning disk, it is characterized in that, described grinding layer comprises polylith conventional abrasive material emery cloth piece and cubic boron nitride or boart boart cloth, along the circumferential direction alternately staggered stacked being bonded on the matrix dish of conventional abrasive material emery cloth piece and cubic boron nitride or boart boart cloth.
2. grinding page or leaf dish as claimed in claim 1 is characterized in that described positioning disk is provided with fixedly circular hole.
