Abstract
The utility model discloses a perforated sectional grinding disk, which is characterized in that the perforated sectional grinding disk is provided with two grinding faces (3) and a central axis hole (4). The grinding plate is dead joint by a binding layer (2) with a plurality of arc segments (1). The grinding faces (3) are provided with a plurality of perforations (5) which are arranged at certain intervals with each other. The perforations (5) are arranged on the grinding faces (3) which are with concentric circles in the same spacing distance. The utility model has the advantages of easy manufacture, low cost, high dimensional precision of the end-face of the grinding piston ring, and good roughness.
Description
Technical field
The utility model relates to a kind of milling tool, especially a kind of abrasive disk that is used for ground and polished piston ring end face.
Background technology
At present, various machine cylinder piston rings upper and lower end face is ground and is adopted cast iron monoblock type abrasive disk to grind, abrasive disk is answered retrofit before using, and labor content is big, thereby its manufacturing cost height, and abrasive disk is whole with workpiece and contacts when grinding, the processing grinding resistance is big, thereby its grinding production efficiency is low, even occurs on the workpiece abradant surface because inhomogeneous cooling is even, workpiece produces the non-uniform temperature phenomenon, causes workpiece abradant surface dimensional accuracy and roughness not to reach the drawing requirement.
Technical scheme
At the problem that above-mentioned abrasive disk exists, the utility model provides a kind of low cost of manufacture, and is easy to use, grinds the production efficiency height, the porous abnormity abrasive disk that Grinding Quality is good.
The utility model combines by some secter pats are bonding, and every secter pat burns till type by the once compacting in mould of green carbon abrasive material through high-temperature baking, and it is disc, has two face machined flats, a central shaft hole.
Also be provided with the perforation that several are intervally installed in addition on abradant surface, perforation is positioned on the identical concentric circles abradant surface of spacing distance.
The utility model adopts the green carbon split of lightweight to make, thereby has and make easy to processly, and cost is low; Because several perforation are arranged on the abrasive disk, abrasive disk and workpiece are short a time of contact, thereby grind the production efficiency height, are because of there being several can store the perforation of cooling fluid on the abrasive disk again, thereby whole abradant surface cooling is more even, and the workpiece size precision is high and roughness is good.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Secter pat 2, adhesive layer 3, abradant surface 4, central shaft hole 5, perforation in the drawings, 1,
The specific embodiment
In Fig. 1, abrasive disk is by six secter pats, 1 usefulness resin bonded laminate, 2 bonding combining, every secter pat 1 burns till type by the once compacting in mould of green carbon abrasive material through high-temperature baking, and it is disc, external diameter is the 200-700 millimeter, it has 3, one central shaft holes 4 of two parallel abradant surfaces, and the perforation 5 of the identical setting of two-layer each interval is arranged on abradant surface, ground floor 5 quantity of boring a hole are 18, and the aperture is the 4-10 millimeter; Second perforation, 5 quantity also are 18, and the aperture is the 4-10 millimeter, and the abrasive disk outer circumference surface is made fillet.
Claims (3)
1, a kind of porous abnormity abrasive disk, it has two abradant surfaces (3), and a central shaft hole (4) is characterized in that: described abrasive disk is fixedly connected with adhesive layer (2) by some secter pats (1).
2, the described a kind of porous abnormity abrasive disk of root a tree name claim 1, it is characterized in that: several perforation that is intervally installed (5) are arranged on abradant surface (3), and perforation (5) is arranged on the identical concentric circles abradant surface (3) of spacing distance.
3, the described a kind of porous abnormity abrasive disk of root a tree name claim 1, it is characterized in that: described abrasive disk is bonded with adhesive layer (2) by 4-8 piece secter pat (1).
