Resin bond diamond wheel for HSS



Resin bond CBN grinding wheel for HSS sharpening, for high-speed steel cold saw hacksaw blade teeth, this grinding wheel choose high-quality raw cubic boron nitride abrasive sand grain and resin bond materials, which makes it has a very strength grinding and sharpening ability, the service life is much longer than common wheels.

PDC CUTTER

图片
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...

Different from the past grinding -HVOF grinding technology

图片
N ew materials often cause a domino effect on aerospace processing technology. Environmental problems have forced a change in materials from traditional chromium electroplating to HVOF spraying coating, which in turn affects the selection of grinding wheels and ultimately the selection of grinding machines themselves.   It swings between two lines The HVOF coating materials in aviation parts has had a positive impact on the aerospace industry. HVOF coating materials are not only more environmentally friendly but also more resistant to wear and tear and therefore last longer. During the migration, there is also a shift in the grinding process used to produce the parts. While resin-bonded diamond wheels are an old standard, vitrified bonded diamond wheels are now more popular because resin-bonded diamond wheels cannot be dressed in machines. This poses a challenge to maintaining consistency. By using a vitrified bonded diamond grinding wheel, one can use a rotary dresser and a rotar...

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...
