Abstract
The invention relates to a combined grinding wheel for carrying out rough and fine centerless grinding on a bar part. A rough grinding wheel and a fine grinding wheel are connected and combined by a bolt; the rough grinding wheel is provided with a step positioning shaft with a width of about 50mm and the step positioning shaft is in clearance fit with a corresponding inner hole on the fine grinding wheel by adopting a basic hole system, so that coaxiality of the combined grinding wheel is ensured; both the rough grinding wheel and the fine grounding wheel adopt super abrasive grinding wheels; the rough grinding wheel has a granularity of 90# to 180# and has a width range of 100 to 200mm; the fine grinding wheel has a granularity of 240# to 325# and has a width range of 150 to 250mm; and the combined grinding wheel has an outer diameter range of 250 to 350mm and has an inner diameter range of 90 to 100mm. According to the combined grinding wheel disclosed by the invention, the existing bar part rough grinding and fine grinding processes can be integrated and by implementing rough and fine grinding machining of the bar part on a centerless grinding machine, production efficiency can be improved and production cost can be reduced.
Description
Technical field
The combined type emery wheel that the present invention relates to a kind of, smart centerless grinding thick for bar class part, is specifically related to a kind of combined type emery wheel for the thick smart centerless grinding of bar class part.
Background technology
The bar class part particularly hard elongated bar part of fragility mainly adopts centerless grinding processing, for example hard alloy bar.The composite that hard alloy bar is comprised of with the good bonding agent of relative toughness the WC particle of high rigidity, thereby it has good mechanical performance, as hardness, wearability, ductility etc.Carbide alloy is extensive use in industry, and requiring can large batch of production hard alloy cutter, but because carbide alloy processing difficulties, processing cost are high, high to the quality requirement of lathe, these have all restricted carbide alloy extensive use.Printed circuit board (PCB) (pcb board) industry develops rapidly in China in recent years.Printed circuit board (PCB) is before dress electronic device, must on panel, carry out the processing such as groove milling, boring, in order to guarantee precision and the production efficiency of the position, hole of printed circuit board (PCB), the use of cutter has just been had to very high requirement, for the drill bit of holing, generally all adopted hard alloy bar on printed circuit board (PCB).
Due to the material behavior of carbide alloy, present stage mainly adopts centerless grinding processing rigid alloy bar material.Centerless grinding is by automatic feeding, bar part successfully to be delivered between emery wheel and guide wheel, completes the cylindricalo grinding of bar part.Main corase grind, the fine grinding twice centerless grinding operation of adopting of existing hard alloy bar processing, two procedures need to adopt varigrained super-abrasive grinding wheel, especially when batch production, completing this two procedures just needs the emery wheel of two kinds of granularities of two centerless grinders to complete, the time of a lot of replacing emery wheels and the centerless grinder doubling have so just been increased, be unfavorable for batch production, and will buy two emery wheels simultaneously and also increased production cost.
Summary of the invention
The object of the present invention is to provide a kind of existing bar class part corase grind, precision grinding process can being integrated, by centerless grinder one procedure, realize the centerless grinding of bar class part, realize a kind of combined type emery wheel for the thick smart centerless grinding of bar class part that working (machining) efficiency is higher, processing cost is lower.
Realize the technical scheme of the object of the invention: a kind of combined type emery wheel for the thick smart centerless grinding of bar class part, by rough grinding wheel, finishing wheel is with bolts to combine; Finishing wheel and rough grinding wheel are drilled with 8 for the through hole of bolts assemblies at end face, and through hole and bolt adopt basic shaft system matched in clearance, thereby have guaranteed finishing wheel and rough grinding wheel axiality;
On rough grinding wheel, there is the step locating shaft of 50mm left and right width to adopt basic hole system matched in clearance with endoporus corresponding on finishing wheel, thereby further guarantee the axiality of combined type emery wheel.
A kind of combined type emery wheel for the thick smart centerless grinding of bar class part as above, the step locating shaft on rough grinding wheel is 140-150mm with diameter of bore scope corresponding on finishing wheel, width is 50mm.
A kind of combined type emery wheel for the thick smart centerless grinding of bar class part as above, rough grinding wheel and finishing wheel all adopt super-abrasive grinding wheel, and rough grinding wheel granularity is 90#-180#, and finishing wheel granularity is 240#-325#.
A kind of combined type emery wheel for the thick smart centerless grinding of bar class part as above, rough grinding wheel width range is 100-200mm, finishing wheel width range is 150-250mm, and the diameter range of combined type emery wheel is 250-350mm, and inside diameter ranges is 90-100mm.
Effect of the present invention is: a kind of combined type emery wheel for the thick smart centerless grinding of bar class part provided by the present invention, it compared with prior art, mainly existing bar class part corase grind, precision grinding process are integrated, can realize the thick fine ginding processing of bar class part in same the same procedure of centerless grinder, shorten process time, thereby can enhance productivity, reduce production costs.
