Abstract
The invention belongs to the field of coated abrasive products and provides a method for testing the performance of a high-speed rotary grinding coated abrasive product. Grinding rods with specified number and load are subjected to surface grinding for a certain time by a high-speed rotary sanding disc. The grinding performance of the coated abrasive product, such as the sanding disc and the like, is judged through the degolding amount and the grinding effect on the surface of the sanding disc. By the method, the grinding performance of the coated abrasive product, such as the sanding disc and the like, which has a relatively high working speed (for example 30 to 80m/s), can be tested; and the method is convenient in operation, high in practicability and has reliable data.
Description
Technical field
The invention belongs to the coated abrasive tool field, relate to a kind of quick plane grinding method of testing, a kind of specifically coated abrasive tool properties of product method of testing of doing the high speed rotating grinding.
Background technology
The kind of coated abrasive tool product is more, and application is wider.If any the laminated that is applicable to hand grinding, band-type product, products such as the abrasive band that is applicable to underload mechanical grinding, high speed high load capacity mechanical grinding, emery disc, page or leaf wheel are arranged also.Wherein, emery disc class coated abrasive tool product is used wider, grinding efficiency height, light, the easy operating of weight, be suitable for the large tracts of land rust cleaning polishing of hull, bridge, also be suitable for the polishing of weld seam, solder joint, burr in the industries such as automobile, bicycle, pressure vessel and defective reconditioning, polishing.
At present, domestic coated abrasive tool industry mainly contains a normative reference to the grinding performance detection of coated abrasive: JB/T 10155-1999 coated abrasive tool coated abrasive grinding performance test method; The coated abrasive grinding performance checkout equipment that Zhengzhou is dynamo-electric with keen determination, green hill, Zhengzhou grinding tool is equipped research institute, Zhengzhou Abrasive Materials, Abrasive Tools, Grinding Inst. (CN) No.1 Huashan R produces also is the testing conditions that meets this standard basically.But along with the progress of science and technology and the variation of product and application, the detection method of above-mentioned grinding performance is not suitable for the application of emery disc class coated abrasive tool, because adhesive property, the heat resistance to product all has strict requirement in the high-speed grinding applied environment; And the detection rotating speed of JB/T 10155-1999 regulation is too low, differs bigger with operating rate 30-80m/s in the practical application, causes easily occurring detecting and using inconsistent situation, is unfavorable for test, production and the work for inspection of product.Though also have the detection method of endless belt grinding at present, the specification of sample band limits sensing range easily.
Therefore, the demand for test and check needs the higher emery disc class coated abrasive tool product grinding performance detection method of a kind of suitable operating rate, and requirement test rotating speed is higher, detection means is reliable and stable.
Summary of the invention
Technical matters to be solved by this invention is: has shortcoming at above prior art, proposes a kind of coated abrasive tool properties of product method of testing of doing the high speed rotating grinding, and easy to operate, the practicality height, data are reliable.
The technical scheme that the present invention solves above technical matters is:
Make the coated abrasive tool properties of product method of testing of high speed rotating grinding, the emery disc of high speed rotating is carried out the plane lapping of certain hour to grinding rod specified quantity and loaded, and the ground effect on what and emery disc surface by the degold amount is judged the grinding performance quality of emery disc class coated abrasive tool product.
The technical scheme that the present invention further limits is:
Test duration is the 60-300s/ root, preferred 80-180s/ root of test duration.
The rotational speed of emery disc is 600-2500r/min.
The grinding rod is 1 group with 20.
Load is to pressurize by the mode of counterweight counterweight, and the counterweight that load is used is at 0.5-4Kg.The emery disc specification is Φ
Outward=150mm, Φ
In=22mm; The grinding track of emery disc is: ring internal diameter 90-95mm, ring width 12-18mm.
Grinding bar matter can be LY12CZ, 45# steel, 201 stainless steels or 304 stainless steels, and the specification of grinding rod is Φ 12mm, long 150mm.Emery disc places on the stainless steel disc, goes up to tighten with chuck.
Advantage of the present invention is: the present invention can carry out grinding performance test at the higher emery disc class coated abrasive tool product of operating rate (as at 30-80m/s), and is easy to operate, practicality is high, data are reliable.For the higher emery disc class coated abrasive tool product of operating rate when the grinding 45# steel, if according to the detection method test of JB/T 10155-1999 regulation, no-spark in the grinding, and performance that can only the testing product grinding initial stage; Use method for grinding of the present invention, obvious spark is arranged in the grinding, can understand the current intelligence in the process in grinding initial stage to latter stage, be convenient to product analysis, the grinding performance in the time of can reflecting product substantially near practical application.
