Product Description

The diamond roller dresser (rotary dresser)is a kind of diamond roller tools for dressing grinding wheel that a working surface with much small grain diamond. The working principle is that conventional grinding wheels or CBN grinding wheels are forming dressed by the diamond roller dresser installed on the grinding machine, and after dressing the grinding wheel and then grind the parts, so that the contour, precision, size of the diamond roller dresser are copied through the grinding wheel to the surface of the parts to be ground
Dressable Wheel Types
Selection of diamond specifications corresponding to grinding wheel particle size
The length and width of the diamond need to be selected according to the size and grit of the grinding wheel.

Grit of Grinding Wheel	Length of Diamond	Width of Diamond	Number of Diamond
120-220#	5mm	0.5mm	3
80-140#	5mm	0.7mm	3
80-100#	6mm	0.9mm	3
60-80#	6mm	1.1mm	4
36-60#	7mm	1.2mm	5

Our Advantages

1 High precision dressing

This is because as the grinding speed increases, the wear of the single point diamond dresser increase, affecting the dressing precision. The tests have shown that the wear of diamond roller dresser is only 1/2000 of that of single point diamond dresser.
2 High-efficiency dressing
Compared with single point dressing, the dressing time of rotary dresser is shortened to 1/10 to 1/100. Especially for the large width forming grinding, the rotary dresser is the whole surface contact grinding wheel dressing, and the single point diamond dresser is single point contact, so the dressing efficiency of the rotary dresser is high. When loading and unloading the workpiece on many automation machine tools, it has been to trim the grinding wheel and the dressing time on the production workpiece can be seen as zero.
3 Complex profile
For complex molding surface, it can trim it, but the single point diamond dresser cannot trim it.
4 Good quality stability
The diamond roller dresser can complete the complex profile finishing in one time in the shortest time by plunge grinding, toguarantee the precision quality stability and consistency of mass production parts. The single point diamond dresser causes the precision quality unstable due to the fast wear, and there is the screw profile of the workpiece surface.

Problems and preventive measures of the diamond roller dresser

No.	Problems		Causes	Preventive measures
1	Poor surface finish		1. Insufficient rigidity of driving equipment 2. Wear of diamond 3. Insufficient dressing 4. Many impurities in the coolant	1. Measure the rigidity of the driving shaft 2. Measure the rotary accuracy of the diamond rotary dresser 3. Measure the diamond exposure of diamond rotary dresser surface 4. Prolong dressing time 5. Replace frequently the coolants
2	Grinding burn		1. Insufficient cooling 2. Improper dressing conditions 3. Improper select grinding wheel 4. Improper parameters of the diamond rotary dresser	1 Check the position of the nozzle and the flow situation 2 Increase feed speed 3 Increase dressing amount 4 Shorten dressing time 5 Select soft grinding wheel 6 Select grinding wheel with loose tissue 7 Adjust diamond exposure 8 Reduce the distribution density of diamond
3	High frequency oscillating		Vibration	1 Check the rigidity of the driving shaft 2 Check the rigidity of feeder 3 Check the PRM of grinding wheel and diamond rotary dresser 4 Check the precision of shaft 5 Increase the power of driving equipment of diamond rotary dresser 6 Check the balance of grinding wheel
4	Noise in dressing	Continuous sound	1. Non-balance of grinding wheel and diamond rotary dresser 2. Excessive dressing resistance	1 Check balance 2 Reduce feed speed 3 Increase relative RPM
		Discontinuous sound	1. Insufficient rigidity of driving equipment 2. Excessive dressing resistance	1 Increase rigidity 2 Reduce feed speed 3 Increase relative RPM
5	Abnormal wear		1. Insufficient cooling 2. Improper dressing conditions 3. Improper select grinding wheel 4. Vibration	1 Check the position of the nozzle and the flow situation of coolant 2 Check if the coolant on the dressing point 3 If feed speed is too fast 4 If the feed amount is too big 5 Adjust material of grinding wheel 6 Select reasonable hardness and tissue of grinding wheel 7 Check driving equipment of diamond rotary dresser and rigidity of feed equipment 8 Check the rigidity of grinding wheel shaft 9 Check the balance of grinding wheel

Customized diamond roller dresser:
When customers order dressing rollers, we need to know the outer diameter size and included angle, radius, width and inner hole size. Then our engineer will send the designed diamond roller drawing to the customer engineer to make sure whether the design meets their requirements.

Product Application

Applications and classification of the diamond roller dresser

1. Formed diamond roller dresser
Use high-quality large-grain natural diamond sintered roller dresser
Manually place diamonds according to part requirements
Repeatedly adjust the positioning accuracy of the diamond dresser
Professional equipment is used for precise dressing and measurement of diamond rotary dresser profiles
This type of dresser can dress the profile of complex and high-precision grinding wheels at one time, with good profile retention and long service life. It is suitable for form grinding of mass production of parts.
2. CNC machine tools suitable for diamond roller dressers
Dresser CNC dressing technology can be applied to all grinding fields, and the CNC control is flexible and the machining process can be easily changed. It can dress grinding wheels of various shapes and is more suitable for small and medium-sized batch processing.
Applications: gears, threads, bearing journals, valves, engine valves, fuel injection components, engine components, transmission components, etc.
