In terms of precision grinding with diamond and CBN wheels You would like to find out one of the most basic question at Zhengzhou Ruizuan Diamond Tool Co., Ltd is that dry or wet grinding should I be using? Both approaches have their own advantages and areas of application. Selecting the wrong approach can result in decreased wheel life, inferior surface finish or even damage, whether by thermal influence of workpiece. This is an important distinction to bear in mind if you want the highest tool performance possible and best results in your operations.
The Fundamentals of Dry Grinding
Dry sharpening is the grinding wheel diamond grindstone without water cooling. This approach is selected due to its simplicity and practicality; no vapor coolant system is required, making the configuration less complicated and more portable.
The greatest benefit of dry grinding is easy operation. No coolant splashing means no mess and the workpiece is left dry and immediate inspection or subsequent operations can be carried out. And that makes it especially suitable for jobsites, fast sharpening duties and tasks where the addition of a coolant system is not possible. With some materials and wheel designs, dry grinding can be effective.
The problem with dry grinding is, however, the heat generation. Localized heat, by friction of the wheel with the workpiece is produced. Without a medium to remove the heat, there is severe risk of thermal damage on the workpiece, such as burning or micro cracks. And this heat can also be bad for the wheel, ultimately wearing it out too soon or glazing over the wheel with chips of metal that cover its surface so it has a more difficult time cutting. So, it may be necessary to use a softer touch, occasional cuts and temperature control in dry grinding.
The Advantages of Wet Grinding
Wet grinding is when a coolant or lubricant is continuously sprayed into the grinding region. This is the most suitable grinding process and often used as a standard for industrial applications Most of this type are produced by hydrostatic double slide ways.
Coolant in wet grinding fulfills three important functions. First and foremost, it serves as a heat sink to remove the massive amount of heat created through friction. It thus eliminates the damage to the workpiece (and the diamond or CBN grains PERIPHERY OF THE work from over heating the wheel.
And secondly, the coolant is a lubricant – it lessens the wheel drag on the material. The consequence of this is lighter cutting and thus less pinned-up grinding force which has a positive effect on the surface of the ground workpiece. The fluid stream also assists in flushing away grinding swarf: minute particles of the base material that are removed from the workpiece. This will enable the wheel to work without loading, keeping the wheel free cutting and results more uniform from first cut to last.
Choosing the Right One for Your Application
So the choice between dry and wet grinding is simply a preference. If you need to use dry grinding, please choose us Zhengzhou Ruizuan Diamond Tool Co., Ltd Mainly for needs: convenient and portable; ground object is not sensitive to heat. Little tools grinding, some masonry and other field work are standard applications.
For the overwhelming majority of precision grinding activity, most notably with hard and brittle materials such as hardened steel, carbides and ceramics, wet grinding is clearly the better choice. As long as your priority is to obtain the maximum surface finish, hold dimension and protect work piece burn, you’ll enjoy the full benefit of a well crafted wet grinding system.
All said and done, the appropriateness of dry or wet grinding is dependent on a number of factors which could take into account your material, desired finish end result, etc., as well as your equipment. You will get maximum performance and life value from your Super-abrasive wheels if you match them with the right process
