无心磨床刀板中镶嵌硬质合金垫刀片,如图所示。现大多数工厂采用铜焊,生产周期长,成本高。为此,经有关单位多次试验,改用SE-7单组份环氧胶粘剂(上海材料研究所生产)粘结,经实际使用后结合面牢固可靠,强度达到使用要求,而且生产周期短,效果良好,保证了产品质量。 SE-7胶粘剂为单组份,使用方便,粘结强度高。如钢-钢粘结,抗拉强度可达52.47MPa,抗剪强度大于27.85MPa。另外,该胶粘剂能耐高温也能耐低温,使用时胶液不流溢,对金属(钢,铝、铜)或玻璃、陶瓷、增强塑料等都有良好的粘结强度和密封性。粘结时,先将硬质合金垫刀片和刀板长槽粘结面
Centerless grinder blades embedded carbide inserts, as shown. Most factories are using brazing, long production cycle, high cost. To this end, the relevant units repeatedly test, switch to SE-7 one-component epoxy adhesive (Shanghai Institute of Materials) bonding, after the actual use of the junction of solid and reliable, the intensity to meet the requirements, and short production cycle, Good effect, to ensure product quality. SE-7 adhesive is a one-component, easy to use, high bond strength. Such as steel - steel bonding, tensile strength up to 52.47MPa, shear strength greater than 27.85MPa. In addition, the adhesive can withstand high temperature can also be low temperature, the use of glue fluid overflow, the metal (steel, aluminum, copper) or glass, ceramics, reinforced plastics, etc. have a good bond strength and sealing. Bonding, the first hard alloy blade blade and blade slot bonding surface
