3-2) Laser Weldable PCD
PCD blade 제작시 laser 용접장비를 사용할수 있도록 기존의 PCD 소재 초경부위에 laser 용접이 가능한 금속층을 접합 합성함
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
PCBN 소재 사이에 초경 재료가 끼어있는 형태로, 기존의 Solid PCBN에 비하여 고품질, 고강성, tool 제작시 양호한 용접성을 제공
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
