Single
Point and One Way Type Diamond Dressers (SPD)
|
|
Single Point Diamond Dressers
have a single whole crystal diamond sintered at the top enabling better
bonding efficiency. The size of the diamond depends upon the size of the
grinding wheel, which has to be dressed. One way or throw-away is also
the same type except that it is meant for one type use, the diamond being
totally consumed and consequently it is low priced.

Multi-Point/Cluster
Type Diamond Dressers (MPD)
|
|
Multi-Point/Cluster
Type Diamond Dressers contains an alternating number of small high
quality diamonds grouped in one layer, positioned accurately and set in
a proper design to replace large single point diamond. It consist of clusters
of 3,5,7,9,13 and 17 small diamond set in various configurations for dressing
larger or coarser and harder grinding wheels.
Advantages : 1) Results in decrease down time and increase productivity. 2) Reduce initial cost. 3) The workload on the diamonds is divided evenly and result for longer life. |

Multi-Point
Roller/Rotary Type Dressers (MPRD)
|
|
The
roller dresser is having number of diamonds on its periphery. The diamonds
are arranged in series. As soon as the diamonds on the indexed position
are completely used up, the roller can be re-adjusted on the shank for
new points. The diamonds can be completely used up and resetting is redundant.
Since more than one point comes in contact with the grinding wheel the
work load on the diamonds are evenly divided and so the diamonds last
long which results in long life of dressers.
Application : 1) Used for larger wheels, where fine dressing is considered important. 2) Also used for cylindrical grinders. Advantages : 1) The diamonds are completely used. 2) The workloads on the diamonds are divided and hence the diamonds last longer. 3) Wheel is dressed more efficiently and finer finish is obtained. |

Multi-Point
Indexable Crown Type Dressers (MPCD)
|
|
A
multi-point diamond dresser is one in which, sharp natural diamonds are
set in a circular crown at right angle to the operating plane. As soon
as the diamonds on the indexed position are completely used up, the crown
can be readjusted on the shank for the new points. The diamonds can be
completely used up and resetting is redundant. Shanks for the crown dresser
are made to customer's specification.
Application : 1) Used for larger wheels, where fine dressing is considered important. 2) Also used for cylindrical grinders. Advantages : 1) The diamonds are completely used. 2) The workloads on the diamonds are divided and hence the diamonds last longer. 3) Wheel is dressed more efficiently and finer finish is obtained. |

Grit
Impregnated Diamond Dresser
|
|
In
this particular type of diamond dressers small diamond particles are mixed
with a special grade of tungsten carbide powder and sintered to a particular
shape. Impregnated diamond dressers are available in coarse, medium and
fine diamond grit sizes.
Advantages : 1) Diamond particles are totally consumed when used in grinding machines for grinding operations. 2) It has a long life since the load is divided on many particles in a tough durable matrix, forming an impregnated tip. Application : Diamond grit impregnated dresser are used in dressing resin, vitreous and rubber bond, fine grit and even so called "grit-free" grinding wheels, as well as boron carbide grinding wheels, dressing single profile threaded and V-profile grinding wheels, for general dressing operations on centreless, cylindrical and surface grinding machines. |

Blade
Type Diamond Dressers (BTDD)
|
|
In
these type of dressers the diamonds are arranged in layers. Diamonds used
are having same flatness and quality and are set in an interlocking arrangements,
which gives a unique advantage of immediately exposing and utilizing the
second layer when the first layer of diamonds are completely used up.
Application : 1) This type of dressers are used for cylindrical grinding, crankshaft grinding, centreless grinding, angular grinding, automatic cycle grinding and profile grinding. 2) It is also used on all types of large grinding wheels where fine profile dressing is important. Advantages : 1) Combines the advantages of chisel diamond dresser with those of multi-diamond tools. 2) Narrow working edge is held absolutely constant until completely used up. 3) No resetting or relapping required. 4) Reduced inventory, costs cut upto 50 percent. 5) High surface finish and ore number of components between regrind possible. 6) Available in two widths and different blade thickness. 7) Can be used for slide dressing. |

DiaForm
Tools/Chisel Type Dressers (CHD)
|
|
Diaform tools are made of high quality
natural diamonds, which is ground and lapped, to high degree and also
have a radius, which gives accurate and consistence performance on the
job.
Application : Diaform tools are used in the form grinding, thread grinding, wheel forming, radius forming and angle forming. |

Diamond
Indentors (DI)
|
|
The octahedron diamond in this tool
is accurately ground, lapped and polished to 120°, which provides
the highest standards of precision and performance.
Application : Diamond indentors are used in hardness machine for testing hardness of metals. |

Impregnated Type Roller/Rotary Type Dressers
|
|
Roller dressers are designed for
continuous precision profiling of wheels used on long production run of
identical components. The roller dresser is impregnated with high concentrations
of diamonds to minimize the space between the diamonds.
Advantages : 1) High degree of accuracy. 2) Reduce rejection as close tolerance is obtained while grinding. 3) Reduce dressing time and frequent replacement of single point dressers. |
|
As the demand of the industry have
developed, there has been a corresponding increase in the demand of Diamond
dressing tools and thus has in turn led to search for new methods of manufacture
which guarantee, the quality of the dressers and also increase in production
economically.
Sunraj Industries manufacture SRI brand Multi-layer blade type diamond dressers in the form of a small plate of special bond, is moulded in bronze body. As soon as the diamonds in the first row is completely used up, the speciality of this tools is that the second layer is immediately exposed without change in setting. |
