Grinding is a primary material-removing process. This is supported by the fact that automobile systems and other end products increasingly demand more exceptional surfaces and tighter feature tolerances on machine parts. Moreover, the fact that manufacturers also use hard and durable materials makes grinding an essential manufacturing procedure. You can also add the fact that improved bonds and grains made for grinding wheels are improving performance. To be a little more specific, the use of creep feed grinding will keep on increasing with time. Creep-feed grinding is different from the conventional surface grinding in that its grinding depth is more substantial and has a slow traverse rate. Some of the things that you need to know about this type of grinding are highlighted below.
Creep-Feed Grinding Does Not Have a Formal Definition
The depth of cut is what generally defines the characteristics of creep-feed grinding. However, there is no precise depth set to mark the transition. Engineers dealing with grinding applications often differ as to when they should consider what they have done as creep-feed grinding. In most cases, they are all usually right.
Creep-Feed Is Both a High-Force and a Low-Force Process
Saying that creep feed is both a high-force and low-force process may seem quite contradicting. However, the statement is valid depending on the perspective that you view it from. During the grinding action, all the particles on the grinding wheel will experience a force that is lower compared to other grinding modes. On the other hand, the power imparted to the part and machine is high. A slow traverse rate is used to compensate for the substantial depth of cut.
Creep-Feed Has Advantages over the Conventional Grinding
Creep-feed grinding has many benefits over the conventional grinding, some of which include shorter cycle time, reduced machine wear, longer wheel life, and fine tolerance. However, there is one significant disadvantage that comes with all these benefits, which is that coolant has to be delivered more precisely.
Intermittent Dressing Is Becoming More Acceptable
The aluminum-oxide wheels that are used in creep-feed grinding usually require continuous dressing because material removing per pass is great. A dressing wheel is applied to the grinding wheel at all times to ensure that it remains sharp when grinding. This need can, however, be avoided by the use of newer abrasive wheels that have ceramic grit. Given how long the ceramic wheels can remain sharp, intermittent dressing can be used.…
