The speed at which the grinding wheel is to be operated often dictates the type of bond. Vitrified bonded wheels should not be used at speeds over 6 500 s.f.p.m. With few exceptions when the speed exceeds this figure resinoid rubber or shellac bonded wheels should be used. Slow table speed Wheel too hard Try softer wheel or make act softer (See #1 above) Feed Lines Wheel not suitable Change Wheel Improper control of traverse or work speed when finishing Change work speed or wheel speed when finishing Improper coolant distribution when truing Readjust coolant flow and direction Improper use of steadyrests

GRINDING Abrasive machining •The oldest machining process"abrasive shaping"at the beginning of "Stone Era". •Free sand was applied between two moving parts to remove material and shape the stone parts. Grinding •Removing of metal by a rotating abrasive wheel.(Very high speed Shallow Grinding Wheel Speed Calculator All Norton grinding wheels are marked with a maximum operating speed in RPM. Most machines and especially CNC machines use Surface Feet Per Minute (SFPM) as an input which requires operators to do the conversion.

Technical information speeds feeds material removal rates Depth of cut and chip per tooth load cutting speed cross reference information To Shop In Canadian Currency Click Carbideanddiamondtooling.ca In centerless grinding the workpiece is held between two grinding wheels rotating in the same direction at different speeds.One grinding wheel is on a fixed axis and rotates so that the force applied to the workpiece is directed downward. This wheel usually performs the grinding action by having a higher linear speed than the workpiece at the point of contact.

Most cylindrical grinding machines offer a rather wide range of work rotation speeds table traverse speeds feed rates and sometimes different wheel speeds as well. The proper selection of these variables in combination with the choice of the grinding wheel has a great bearing on the results and the economy of the grinding operation. 5 Axis Precision Cylindrical Pinch/Peel Grinding Aggressive Grinding Service has 12 Rollomatic ShapeSmart NP5 grinders ideal for cutting tool blank preparation as well as punches taps drills. The NP5 is a five-axis pinch and peel grinding machine for the cylindrical grinding of carbide HSS and stainless steel components.

WHEEL SPEED Grinding wheel speeds commonly used in precision grinding vary from 5 500 to 9 500 fpm. You can change wheel speed by changing the spindle speed or by using a larger or smaller wheel. To find the wheel speed in fpm multiply the spindle speed (rpm) by the wheel circumference (inches) and divide the product by 12. External grinders are used for grinding cylindrical surfaces and to produce external cams eccentrics and special form on the outside diameter of the work.

The recommended wheel speeds during dry grinding is in the range of 3000 to 4500 SFPM (15 to 23 m/s). The higher wheel speeds may cause burning of the tool edges. In wet grinding wheel speeds in the range of 5000 to 6500 SFPM (25 to 33 m/s) provide excellent results. In general the higher speeds improve both wheel life and metal-removal rates.

Precision Thru-feed Infeed Centerless Grinding

Centerless Grinding. Centerless grinding is an OD grinding process. It differs from other cylindrical processes in that the workpiece is not mechanically constrained. On traditional OD machines the work is held between centers or chucked and rotated against the faster spinning grinding wheel by an external motor usually located in a workhead.
