PCD diamond engraving tools



The Stone Engraving Tool

(PCD Stone Carving tool) is used to engrave pictures, words and characters on granite, marble, jade, porcelain,ceramic, aluminum and brass.



Features 

1. The center sharp knife of the PCD stone engraving tool features long service life and good adaptability. It is particularly suitable to engrave granite, marble, jade, porcelain,ceramic, aluminum and brass. Its maximum engraving depth can reach 1mm.

2. The flat bottom knife is used to engrave characters with smooth edges. The size of the engraving characters ranges from 3mm to 8mm. The knife features fast engraving speed and long service life. Its maximum engraving depth can reach 4mm.

3. The milling bedplate cutter can mill the groove at the bottom of the engraving picture. The milling cutter features fastprocessing speed and high work efficiency. You can choose milling bedplate cutters of different sizes 

according to the size of the processing surface. The recommended engraving depth of the milling cutter is 2mm.



Advantage
1.good adaptability to all kinds of carving machine for carving marble, granite ,jade, ceramic tile ,glass, acrylic and other metals.

2.long tool life,good stability of tools,good abrasive resistance,high sharpness,good carving roughness without chipping.

PDC bits introduction

PDC bits have the fixed blades with large, hard, abrasion-resistant cutters manufactured from a boned mass of microcrystalline synthetic diamonds and designed to excavate hole by shearing the formation while tricone insert bit works by crushing it.

 Softer the formation and homogenous smaller the number of blades and bigger the size of the PDC cutters.

 They drill very fast in soft to moderately hard formations as Sand, Shale, Clay and Siltstone.

 PDC bits have the advantage that they last longer- you can usually drill shoe to shoe, eliminating tripping, and can often be rerun (with or without refurbishment) on subsequent wells, reducing the cost per foot if you have a number of wells to drill.

 The PDC bit is now almost the default choice unless you can't use a PDC bit: really plastic, sticky formations or really hard formations (and PDC technology is encroaching into these areas with depth of cut limiters and the like).

 In fact, as more and more drillers are only accustomed to using PDC bits, like the "top driver driller" phenomenon, we are loosing the "art" of roller cone drilling. PDC bits are essentially fire & forget: when they wear out the ROP drops and you pull them; it's very unusal for them to fall apart, whereas with roller cones, there is always the risk of dropping a cone if you push the bit a little too long!

 PDC technology has come a long way in abrasive formation. The drillers doubling their footage drilled with a PDC bit (same area and sandstone formation) in only a couple of years. Such as East Texas area where the Travis Peak formation is over 2000' of consolidated sandstone. Ten years ago, a well would consist of over 20 insert bits just to get through, where now it takes 1, 2, or 3 PDC bits depending on exact location.

 Overally rig time has been reduced from 90+ days on a well to 15.

 Nowadays the casing equipment is PDC drillable and the cement will not ever be too hard for a PDC

What's the difference of PCD and CBN?

Fine,smooth cuts, geometrically perfet threading ,grinding, milling applications can be achieved with using the industries top two materials -Polycrystalline Diamond and Cubic Boron Nitride,commonly  refered as PCD and CBN respectively.

 Each with their own characteristics when used in tool making,these materials willprovide long lasting ,rugged tooling for arduous applications used in making parts for the automotives,aerospacce and mining industries and more.

 Perhaps the most distinct diference is in their thermal stability . Unlike PCD tools used on nonferrous materials, CBN tools maintain thermal stability and hardness levels in higher temperature applications. CBN characteristics include its abrasion rresistnce,thermal and chemical resistance and maintaining sharp edge when cutting which are most effective when machining ferrous materials.
