Embodiment 1

[0047] The preferred formula of the high-precision non-network ultra-thin resin grinding wheel cutting sheet of the present invention comprises the raw materials of the following weight percentages:

[0048] Abrasive: 38% white corundum powder,

[0049] 8% cryolite powder,

[0050] 12% green silicon carbide,

[0051] 10% monocrystalline silicon powder;

[0052] Resin binder: 11% powdered phenolic resin,

[0053] 14% liquid phenolic resin;

[0054] Excipients: 7% carbon black.

[0055] The preparation method is as follows:

[0056] (1) Stir the raw materials evenly in an automatic mixer for more than 6 hours, and then let them stand naturally for 8-10 hours, during which the substances inside are continuously fused, interpenetrated and decomposed;

[0057] (2) Carry out 72-96 hour storage molecular static in the constant temperature and humidity preservation cabinet that temperature is 25 degrees centigrade then, and humidity is 45%;

[0058] (3) Then, at a temperature o...

Abstract

The invention provides a high-precision net-free ultrathin resin grinding wheel cutting blade which does not adopt a conventional grinding wheel blade ring glass fiber reinforced net. The grinding wheel cutting blade manufactured by the manufacturing method belongs to a high-environment-friendliness innocuous and harmless product, and can meet environment-friendly requirements such as SGS; a producing process is reasonable, rigorous and scientific; the manufactured grinding wheel cutting blade has a thickness ranging from 0.1 mm to 1.0 mm, is uniform in structural organization, is extremely low in hardness deviation, has flatness within + / -0.02mm, has lot thickness error within + / -0.03mm, is good in self-sharpening performance, is sharp in cutting, is high in cutting efficiency, is free ofburrs during workpiece cutting, is free of burns, is flat and bright in cut end opening, and even achieves the mirror effect; and cut materials can be saved to the greatest extent, and material wastecost is greatly reduced for enterprises.

Description

technical field [0001] The invention relates to a high-precision non-network ultra-thin resin grinding wheel cutting piece and a preparation method thereof. Background technique [0002] Grinding wheel is the most important type of abrasive tool in grinding process. The grinding wheel is a porous body made by adding a binder to the abrasive, compacting, drying and roasting. Due to different abrasives, bonding agents and manufacturing processes, the characteristics of grinding wheels vary greatly, which has an important impact on the processing quality, productivity and economy of grinding. The characteristics of the grinding wheel are mainly determined by factors such as abrasive, particle size, bond, hardness, structure, shape and size. [0003] At present, the grinding wheels produced by the traditional one-time stamping process in the market must be equipped with glass fiber reinforced mesh, and the thickness error is often more than 20 to 30 wires. It is not precise an...
