How do efficient abrasive manufacture

Using diamond grinding wheel, generally feed rate can not be too large, how to achieve efficient grinding it?
1, high-speed grinding
Speed ​​by increasing the diamond grinding wheel speed to achieve improved quality of grinding and grinding removal process method. Speed ​​grinding has the following advantages:
(1) at a certain amount per unit time under ground except  PINEZONE ceramic flap disc when the grinding wheel speed, abrasive cutting thinner, which makes the load of the individual abrasive grains reduce the diamond grinding wheel to improve durability;
(2) grinding the surface roughness is reduced; After improving diamond wheel speed, abrasive cutting thinner, making the wheel relative feeding quantity is small, the roughness is also reduced.
(3) the normal grinding force is reduced, improving the accuracy of the workpiece.
2, creep feed grinding large depth of cut PINEZONE abrasive fibre disc  big creep feed grinding, also known as deep grooves cut deep grinding grinding or motility. It is based on a large grinding depth (up to 30mm) and low table feed (3 ~ 300mm/min) grinding.
3, abrasive belt grinding with high-speed motion as grinding tools, grinding various surface method called belt grinding. Advantages belt grinding are:
High (1) productivity, abrasive belt on the collections of sharp, cutting large; sand bandwidth grinding large area, high productivity than the grinding wheel 5 to 20 times;
(2) grinding, low energy consumption, due to the light weight belt, tensioner wheel and small contact size, high speed small moment of inertia, so little power loss;
Good (3) processing quality, it can ensure constant work, less heat, no dressing, abrasive sharp, good belt cooling conditions, to  PINEZONE cut off wheel ensure accuracy and small surface roughness values.
(4) belt is soft, can stick to the shaping surface grinding, suitable for a variety of complex-shaped grinding surface.
(5) belt grinder structure is simple, safe operation.
The disadvantages are: rapid depletion belt, belt grinding small diameter holes can not be processed, blind holes, and can not be processed stepped cylindrical gear.
Of course, when using high-speed grinding, you must make sure the machine operating speed must be below the safe use of diamond grinding wheel line speed, and the use of creep feed grinding when large depth of cut, but also to ensure the safety of the grinding time.
