Machining vibrations, also called chatter, correspond to the relative movement between the workpiece and the cutting tool.The vibrations result in waves on the machined surface. This affects typical machining processes, such as turning, milling and drilling, and atypical machining processes, such as grinding.A chatter mark is an irregular surface flaw left by a wheel that is out of true in ...

Apr 02, 2004· The average Crystal Lake grinder is about the size of a Hardinge lathe. the machine sets on a sheet steel cabinet just like a Hardinge does. Crystal Lake grinders are lineshaft driven through flat belts. Now the good folks at Crystal Lake know that nobody has the shaft brackets hanging from their ceilings any more, so they supply them.
Mar 12, 2016· The earliest machines where produced at the turn of the century. Crystal Lake Grinders is still in business, but haven't made any new machines for quite a number of years. The belt driving assembly is suspended from the overhead rollers and reduces vibration to nearly eliminate chatter at the work piece.
An important part of the Crystal Lake machine was the drive assembly - a remote overhead system of wonderfully vintage appearance that is still used today (though now mounted as part of a more neatly contrived integral system). A tried-and-tested arrangement, it removed from the machine any hint of vibration from the motor or belts.

The vibration behavior of the grinding machine spindle system is conditioned by both the vibration characteristics of the assembly components, i.e. shaft–bearing–housing system and the external grinding process forces. While vibration characteristics of the shaft–bearing–housing components were approached by many reliable mathematical ...
Optical quality surfaces on non-ferrous materials are commonly produced with single crystal diamond tools and precision turning machines. To add ferrous and brittle materials to the list of diamond turnable materials, a process know as elliptical vibration assisted machining (EVAM) has been developed.

Grinding Cut Too Heavy Slow down your infeed amount so the machine is taking a lighter cut. Or, if you're traverse grinding, slow down your traverse fee. This will allow for your wheel to cut more freely and prevent any possible vibration or bouncing. Wheel Too Hard Try using a softer wheel, or make the wheel act softer.
