3-1) Sandwich PCD
Sandwich PCD is composed of PCD layer that is sandwiched by tungsten carbide layers in both(top & bottom) sides, primarily used for drilling application.

T : Blank thickness
t : Diamond layer thickness

PCD Grade : “FS”, “MS”, “CS”

Physical Dimension : (Half-moon of blank diameter : 51㎜, 61㎜)

Blank thickness(T)	Diamond layer thickness(t)
1.5mm ±0.05	0.5mm ±0.10
2.0mm ±0.05	0.8mm ±0.10
2.5mm ±0.05	1.0mm ±0.10

Product Offer : Blank Type (51 & 61Ø half-moon) Wire EDM Cut Type ( , per customer’s spec)

3-2) Laser Weldable PCD
An extra metal layer of PCD tungsten carbide substrate allows a new laser welding that brings lots of benefits over the conventional brazing for manufacturing PCD tipped blades.

Product Offer :

Blank (52㎜diameter x 3.2㎜thick), (62㎜diameter x 3.2㎜thick)
Cut-pieces (wire EDM cut)

Benefit

Exceptionally high bond strength at the welding joint between PCD and tool body.
No risk of tool failure from unstable thermal stability related preblems.
Cost effectiveness from no brazing.
Offers both less health hazardous and cleaner environmental operation.

Application for Laser Welded PCD Tools

Saw blades for cutting tiles, rocks, cement boards.
Saw blades for road grooving cement and asphalt.
Core bits for drilling rocks, bricks, ceramics, etc.
Others (like conventional PCD tools)

3-3) Double-sided PCBN
With a tungsten carbide material sandwiched in between PCBN materials, compared to an existing solid PCBN, it offers a higher impact strength and better bonding quality as highly rigid PCBN tools.

3-4) ADICO PCBN Cutting Tool Product Application Areas

The range of workpiece materials that Adico PCBN can successfully machine is constantly ex-panding, but the main material groups are:
1. Hardened steels 2. Hard facing alloys 3. Chilled cast iron 4. Pearlitic grey cast irons		5. Sintered iron 6. Superalloys e.g. Inconel 718 7. Powder metal e.g. automotive valve seats
ADICO PCBN Products		Successful machining applications have been established in the automotive, aerospace, and manufacturing industries, and some examples are:
High CBN-content PCBN ADN10, ADN16
ADN10	gray cast iron cylinder boring (GG 20/25) nodular cast iron tuning (GGG50, 38-42 HRC with good cylindricity & higher feed rates than other tools)
ADN16	brake drum tuning (GG20) TiAl₆V₄ exceptionally good for tuning applications internal gear tuning with very good surface finish ball nose end milling (CF53, 62HRC) with extremely high edge-stability and better surface quality sintered geared tuning (SK72-01, 60HRC)
Low CBN-content PCBN ADN35C, ADN35N, ADN40C, ADN45N, ADN45C, ADN55N
ADN 35C ADN 35N ADN 40C ADN 45N ADN 45C ADN 55N	finish machining difficult grey cast irons (milling) and hardened steels severe interrupted turning of hardened steels and die steels continuous & interrupted turning on hardened steels and valve seat turning applications (both continuous and interrupted) of hardened steelsand cast irons for superior surface finish finish turning on case hardened steels and crank shaft, cam shaft, and gears moderate interrupted hard turning, finish hard milling & high speedcontinuous turning It gives an exceptional surface finish to workpiece andprovides toughness to cutting tools grooving cam shafts & surface milling (cold work tool steel) mild & slight interrupted turning of gear shafts
