一种用于激光烧结的砂轮装置A grinding wheel device for laser sintering

技术领域technical field

本发明涉及砂轮制造技术领域，特别是涉及一种用于激光烧结的砂轮装置。The invention relates to the technical field of grinding wheel manufacturing, in particular to a grinding wheel device for laser sintering.

背景技术Background technique

砂轮又称固结磨具，是由结合剂将磨料烧结成一定形状、具有一定结合强度的固结磨具。砂轮的形状通常为中央有通孔的圆形形状。砂轮通常由磨料、结合剂与气孔构成。超硬砂轮主要采用电镀、烧结、高温钎焊等工艺制造而成。Grinding wheels, also known as bonded abrasives, are bonded abrasives in which the abrasive is sintered into a certain shape and has a certain bonding strength by a bonding agent. The shape of the grinding wheel is usually a circular shape with a through hole in the center. Grinding wheels are usually composed of abrasives, binders and pores. Superhard grinding wheels are mainly manufactured by electroplating, sintering, high temperature brazing and other processes.

在烧结型超硬砂轮中，在金属基体中随机分布的磨料容易产生偏析和聚集。在磨粒富集区，磨粒浓度高、容屑空间小；这就使得在采用该砂轮进行磨削加工时，空间容易造成堵塞，进而降低磨削效率。在磨粒稀薄区，磨粒浓度低；这又使得砂轮不能有效参与磨削：磨粒因承载或冲击力过大而易于破碎脱落。In the sintered superhard grinding wheel, the randomly distributed abrasive in the metal matrix is prone to segregation and aggregation. In the abrasive particle enrichment area, the abrasive particle concentration is high and the chip space is small; this makes the space easy to cause blockage when the grinding wheel is used for grinding, thereby reducing the grinding efficiency. In the thin area of abrasive grains, the concentration of abrasive grains is low; this in turn makes the grinding wheel unable to effectively participate in grinding: the abrasive grains are easily broken off due to excessive load or impact force.

在电镀型超硬砂轮中，砂轮磨削的出刃高度较低；而且，镀层金属机械的包埋镶嵌磨料把持力较弱，在重荷高效磨削中容易脱落。虽然可以通过增加镀层金属的厚度有效增加其把持强度，但是，镀层金属厚度的增加会导致磨料出露高度降低、容屑空间减小，进而容易造成砂轮堵塞，磨削热难以及时排出，又使得工件表面容易发生烧蚀。In the electroplated superhard grinding wheel, the grinding wheel has a low edge height; moreover, the embedded inlay abrasive of the plated metal machine has a weak holding force, which is easy to fall off during heavy-duty high-efficiency grinding. Although the holding strength can be effectively increased by increasing the thickness of the coating metal, the increase in the thickness of the coating metal will lead to a decrease in the exposed height of the abrasive and the reduction of the chip space, which will easily cause the grinding wheel to block, and the grinding heat is difficult to discharge in time, which makes the The workpiece surface is prone to ablation.

由此可见，在现有技术中，尚无一种能制造组织均匀、力学性能与加工性能均比较高的、用于激光烧结的砂轮装置。It can be seen that, in the prior art, there is no grinding wheel device for laser sintering which can manufacture uniform structure and relatively high mechanical properties and processing properties.
