Cluster Dressers

Cluster Dressers
  • Cluster Dressers
Ask For Price
Cluster type diamond dressers consist of a number of small natural diamond of good crystal character, set in a geometric pattern in single layer and sintered into a special wear resistant bond.

The cluster type diamond dresser is ideal for coarse or rough dressing of grinding wheels in sizes up to 80 grit (mainly rough grinding or grinding to eliminate imbalance). The diamonds can be fully utilised without re-setting or re-sharpening.

Dressing costs are substantially reduced as the diamonds used in this type of dressers are much smaller in size than single point diamond dresser, so they are much economical.

Cluster type diamond dressers give rapid-dressing and produce a consistent even surface on the grinding wheel. These dressers are resistant to shock and impact.

The dressing face of the cluster type diamond dresser should be set at an angle of 90° to the grinding wheel so that all the diamond points are in contact at the same time.

Depth of cut per stroke of the dresser: 0.01-0.05 mm max.

Feed rate - in mm per revolution:

0.3 - 1.5 mm max.

Finer infeeds & smaller cuts will produce higher surface finishes. Normal wheel speeds should be used.

An adequate supply of coolant should be used both before and during the dressing operation, in order to prolong tool life.

Multipoint Crown

Multipoint Crown
  • Multipoint Crown
Ask For Price
A multipoint crown 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 re-indexed on the shank for new points. Shanks for the crown are made to customer's specifications.

 APPLICATIONS :
  • All types of large wheels where fine truing is considered important.
  • Specially recommended for cylindrical grinders.
 
 ADVANTAGES :
  • The diamonds can be completely used up and resetting is redundant.
  • Since two or more diamonds come in contact with the wheel the work load on the diamonds is divided and the diamonds last longer.
  • A large area of the wheel is dressed more efficiently in a relatively shorter time than a single point.
  • As several points are in use simultaneously the feed may be safely increased.
  • Finer finish is obtained on the wheel due to the crystal shape of the diamonds employed.
  • Can be used for side dressing.
 
 SIZES :
  • MIC-24 with 24 Diamonds for wheel size up to 600 mm diameter wheel.
  • MIC-36 with 36 Diamonds for wheel size above 600 mm diameter wheel.

Multipoint Disc

Multipoint Disc
  • Multipoint Disc
Ask For Price
Multipoint disc dressers are normally used in small grinding wheels on internal grinding machines. the diamonds are set evenly in rows across the face of the disc. First class needle shape diamonds are used, set in a special sintered bonds. multipoint disc dresser are perfectly simple to use. Its operation is basically the same as that of a single point diamond dresser except that, after each row of diamonds has been used, new points can be put into operation simply by rotating the disc slightly.

An ample supply of coolant and depth of cut of 0. 02 - 0. 03 mm. Max are prerequisite for long tool life. multipoint disc dressers can be used at any angle and therefore in any application.

To optimise the life of multipoint disc type dresser, we recommend that the complete disc be turned 180o from time to time to utilise the self sharpening effect produced by wear.

Diamond Grit Dressers

Diamond Grit Dressers
  • Diamond Grit Dressers
Ask For Price
Diamond grit impregnated diamond grit dressers have been developed from multi-point dressers. In contrast to the latter they are manufactured from diamond grit rather than a larger number of small natural diamonds. The advantages of the diamond impregnated dresser lie in its exceptional sharpness, which results from sharp edges and points of the diamond grit.

Diamond grit impregnated dressers are ideally suited to the following applications, dressing resin, vitreous and rubber bond, fine grit and even "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.

Diamond grit impregnated dressers are more economical because of their low initial cost and their resistance to shock and impact which prevents shattering.

Dressing times are reduced as higher feed rates can be used. There is an unlimited number of
sharp pull-out-free cutting edges contained in the crushed diamond grit.
..

Diamond grit impregnated dressers demand greater care in selecting the correct dresser for a given application. The bond and diamond grit size used are both variable according to the type of grinding wheels to be dressed. The size of the diamond grit particles should be matched to the grit size of the grinding wheel.

Instructions for Use:
Normal dressing speeds are used. A plentiful supply of coolant should be provided both before and during dressing to prolong dresser life. The diamond grit impregnated cutting face of the dresser should be set at an angle of 90° to the grinding wheel to be dressed, so that all the cutting edges of the diamonds grit are able to make contact with the wheel face.

The feed rates used may be double of those used with single-point diamond dressers.

Throw-Away Diamond Dressers

Throw-Away Diamond Dressers
  • Throw-Away Diamond Dressers
Ask For Price
Throw-away type diamond dressers are made of small selected crystal shape or octahedral diamonds, mounted in a matrix. Only one cutting edge is presented to the grinding wheel.

Diamonds for throw-away type diamond dressers are selected for their structural strength, degree of sharpness and lack of deterimental flaws. The proper selection of size and quality appropriate for a given application requires qualified and experienced judgment.

As the name suggests is really a throw - away dresser that means no maintenance, no re-setting of diamond required.

They are used for turing and dressing small and medium sized wheels. For larger wheels with small widths they are used only in profile dressing applications.

These tools are not suited to dress wheels with grit size coarser than 60 mesh.

For your reference we have given few of the standard tools as per European & American specifications, however it can be manufactured as per your specifications.

Single Point Diamond Dressers

Single Point Diamond Dressers
  • Single Point Diamond Dressers
Ask For Price

Single point "bruted diamond" dressers are made with selected "congo rounds" mounted in a matrix.
A Single cutting edge is presented to the grinding wheel.
 
Diamonds for single point dressers are selected in accordance with quality and size. The question of using a superior, average or commercial quality, depends on the grinding finish required and the machines and working parameters.
 
We offer three grades namely A, B & C for all the diamond size, Availability: 0.25 Ct to 5.00 Ct

Natural Point Diamonds: The Diamond points are naturally formed. (Not man made like grades
A, B, & C) This is a gift of nature. Natural Point Diamond Dressers have high form retention properties. Availability: 0.10 Ct to 2.50 Ct
 
Guideline for single-point diamond dressers :

Considerable care should be taken in mounting the diamond dresser in position. Diamonds are sensitive to shock and impact.
 
The dresser must be clamped rigidly in place to avoid vibration once dressing begins.
 
An ample supply of coolant should be directed at the diamond point before dressing begins, as the sudden application of coolant to the diamond once it has heated up can cause it to shatter.
 
The diamond holder should not be set directly on the center of the grinding wheel, but at an angle of
5-15 to the direction of rotation of the wheel so that it appears to be "trailing"
 
At normal wheel peripheral speeds, dressing rates of approximately 20-25 m/sec can be achieved.

The maximum depth of cut achieved per dressing pass is 0.03 mm or on fine grit wheels,
approximately 0.005-0.01 mm.

The cross feed rate is dependent upon grit size and can have a marked influence on the quality of the finish imparted to the grinding wheel surface. The lower the feed rate, the finer the surface finish.
We would recommend the following feed rates per revolution of the grinding wheel.
