Recommended tool types and parameters for different workpiece materials
| Workpiece material category | Specific examples | Recommended tool type | Recommended tool material | Cutting speed range | Feed rate range |
|---|---|---|---|---|---|
| Non-ferrous metals | Aluminum alloys, Copper alloys, Magnesium alloys | PCD milling cutter, turning tool | PCD | 300-800 m/min | 0.1-0.4 mm/tooth |
| Cast iron | Gray iron, Ductile iron | PCBN turning tool, milling cutter | PCBN | 100-300 m/min | 0.1-0.3 mm/tooth |
| Hardened steel | 45-65 HRC hardened steel | PCBN turning tool, milling cutter | PCBN (high CBN content) | 80-200 m/min | 0.05-0.2 mm/tooth |
| High-temperature alloys | Inconel, Titanium alloys | PCBN tools | PCBN | 50-120 m/min | 0.05-0.15 mm/tooth |
| Composites | Carbon fiber, Glass fiber | PCD milling cutter, drill | PCD (fine grain) | 200-500 m/min | 0.05-0.2 mm/tooth |
| Powder metallurgy | Iron-based, Copper-based | PCBN tools | PCBN | 60-150 m/min | 0.08-0.2 mm/tooth |
Choose appropriate tools according to machining requirements and conditions
Tool hardness should be 2-3 times higher than workpiece material; PCD for non-ferrous, PCBN for hardened steel and cast iron.
For high-temperature environments, use PCBN; PCD operating temperature ≤700℃.
Avoid chemical reactions between tool and workpiece; PCBN does not react with iron group elements, suitable for steel and iron.
Consider tool cost, machining efficiency, and service life; PCD/PCBN recommended for long runs.
Recommended cutting parameters for different tool materials
| Tool material | Applicable material hardness | Recommended cutting speed | Recommended feed rate | Depth of cut | Cooling method |
|---|---|---|---|---|---|
| PCD tools | Non-ferrous < 300HB | 300-1000 m/min | 0.05-0.4 mm/tooth | 0.1-3 mm | Dry or minimal lubrication |
| PCBN tools | 45-65 HRC | 80-300 m/min | 0.05-0.3 mm/tooth | 0.1-2 mm | Coolant recommended |

Common questions about tool selection, usage and maintenance
The choice of PCD grain size depends mainly on the workpiece material and surface finish requirements. Coarse grain (10-50μm) is suitable for roughing and interrupted cutting, offering better wear resistance; fine grain (2-10μm) is suitable for finishing, providing better surface quality.
PCBN tools are mainly suitable for machining difficult-to-machine materials with hardness above 45HRC, such as hardened steel, cast iron, high-temperature alloys, and hard metals.
Delivery time for custom tools depends on complexity and quantity. Simple non-standard tools typically take 10-20 days, while complex combined tools may take 15-30 days. Express service is available for urgent needs.
Key factors for extending tool life include: selecting appropriate cutting parameters, using suitable coolant, regularly inspecting tool wear, timely regrinding, and maintaining machine accuracy and stability.
