Pai and Pai Enterprices,the flagship company of the Pai and Pai group was established in 1971 as the distribution firm for leading manufactures of Metal finishing chemicals,electroplating plants and other allied equipments. The Pai and Pai group comprising of conglomerate of companies,is engaged in consulting,manufacture,distribution and support services of wide range of products to meet the specialized needs of various industries. Pai and Pai Enterprices plays pivotal role in granite industry by manufacturing and marking diamond saws and tools,circular saws,edge cutting saws and multi blades.Diamond segments supplied by us are mainly used for cutting cutting all kinds of granite blocks and slabs.The advantages are fast cutting,speed,smooth cutting and has long life....

High quality diamond saw cores for the stone processing industry using German technology.TYhese steel blades have the highest quality of tolerance and flatness.

All cores are Rockwell tested at various location on the diamond core.

We supply customized products-bore holes and PCD are machined for concentricity in the tolerance range of H7.

For high stress applications the straws in the circular saws are specially laser cut to prevent cracks and premuture break down.

We are committed to provide superior value-added services.Service means prompt response to customer inquires and timely delivery.

We are recognized as an approved supplier of wide variety of cutting saws for shaping variety of granites.

Our service concept is ONE STOP SOURCE for immediate supply on call;supplying materials for global presence.

We supply diamond wires for block squaring and also supply multi wire for slab cutting.

Rule for Saw selection

In selecting a circular saw for cutting stone,rocks,refactories or other such materials,the following points must be carefully considered.

the material to be cut

Cutting quality and thickness desired

Service life of the saw desired

Machine characteristics

Only after properly considering the above,it is possible to decide select the correctly decide the saw dimension and the segment specifications.The primiarly the hardness and abrasivity of the stone or rock would decide the segment specifications.At the same time,however,one must also consider whether the saw is to provide basically a high output or long service life.

Fast cutting saws naturally have a long life,since s softer bond and/or a lower bond is used.This type of saw can be used satisfactorily only on sturdy and nearly vibrations machines and that too at high peripheral device only.Conversely, saws for a long service life must operate at low cutting rates and require higher driver outputs.Machines suseptible to vibrations and having somewhat lower peripheral speeds could also be used with such saws,but the same time low wahes and machine overheads.

Peripheral speed

Optimum peripheral speed is closely relatd to the hardness and abrasivity of the material to be cut.Ideal sectionwill depends on the spindle speed,spindle drive output,saw diameter and specifications of the saw segments and will be reflected in the cutting efficieny or the ultimate performance of the saw.

Coolant Capacity

Sufficient quantity of coolant is very important and it must be given properly into the area of contact between the saw and the material cut.Clean cooling water with coolant additives ,should be used to ready the water and tear.

Running-IN

Running-IN period for circular saws on any machine is quite normal.Therefore it is necessary to take the first few cutes rather slowly and then gradually increase the cutting speed and the depth of the cut which in turn increase the efficieny of the saw.

Stocking

On receipt of the saw blank,k8indly handle the blades by the handling hole and not by the center bore.Kindly note it can create damage to the center bore if done so. It is advaisable to store the segmented saw on the flat surface or hung by its bore n a well.Do not rest it on the ground against the wall as it tend to bend.

Brazing

The brazing of the segments is very critical and the following parameters should be followed-

Always use silver blazing foil of 43%

While brazing the temperature should remain between 600 degree C-675 degree C.Exceeding the temperature damages the segments and the blanks resulting in lower life.

Trouble Shooting

Uneven blade wear

Wear on the Saw body

Blade Woobles

Cracks in steel center

Blade will not but

Short blade life
