How to make the abrasive tools that have been made soft down? The ceramic bond abrasive is immersed in a sodium hydroxide or potassium hydroxide solution, heated to the boiling point, and the concentration of the alkali solution and the boiling time are controlled to appropriately reduce the hardness of the abrasive. Refer to Table 1 for the compatible concentration boiling time. Table 1    Alkali treatment to reduce the hardness of the abrasive reference table Abrasive Grit Boiling time （ h ） Original hardness of abrasive tool K L M N P Q R S T Y Alkaline concentration （ % ） 10 20 30 10 20 30 10 20 30 40 24# 124 123 234 234 113 123 223 123 234 345 235 46# 124 234 345 356 134 234 245 112 123 234 123 60# 124 123 234 346 123 234 235 112 123 233 133 The strength of the grinding wheel after the treatment will be reduced. Therefore, it must...

Single crystal diamond burnishing tool

图片
  The workpiece usually appears some tiny tool marks after machining. It requires one more step – “polishing” for reach superior surface finishing. However, this work slows down production efficiency a lot. “More Super Hard” launches a burnishing tool which is made of single crystal diamond now. The tools apply a certain pressure on the surface of workpiece, it generates plastic flow on the surface of workpiece, and then fill in the low through, that to achieve better surface finishing.   Single crystal diamond burnishing tool not only improves the corrosion resistance and surface quality of the workpiece, but also improves the machining efficiency.   1. The hardness of single crystal diamond burnishing can reach 10,000 HV, with the characteristics of strong wear resistance and low friction coefficient, it only takes a few seconds to process the surface of the processed workpiece to the required surface accuracy. 2. The efficiency of single crystal diamond burnishin...

PDC CUTTER PDC Cutter  is a kind of composite material composed of diamond and hard alloy matrix, pdc cutter with high hardness and good wear resistance. Pdc cutter  suitable for soft to medium hard geological drilling, the impact toughness and high thermal stability, heat resistance temperature can reach 750 ℃ (two minutes), these pdc cutter  have plane and various groove surface type, we can according to user needs and design type slot, grinding, polishing and chamfering. Here are our different series of PDC Cutter.   A, W series PDC cutter PDC Cutter  in drilling and rock work face top surface of tooth structure become a work site, the structure of the tooth surface line row "teeth" become a blade, cutting rock power and efficiency is better than no tooth of planar drill PDC tooth, PDC Cutter  tooth type outside using drill tooth bit, PDC can improve drilling teeth rock fragmentation efficiency obviously. Especially for the prone skid fo...
