PT The semiconductor equipment industry demands high precision and exceptional surface finish for its module plate components, which are typically made of hardened steel, alloyed materials, or composite structures. These components are used in wafer processing chambers, vacuum systems, and heat management units, where tight tolerances and minimal surface defects are critical for optimal performance. The typical machining process involves roughing, semi-finishing, and finishing operations, with milling being one of the most frequently used operations to achieve dimensional accuracy and surface quality.
Challenges in this application include high material hardness (often exceeding 45 HRC), strict surface roughness requirements (Ra ≤ 0.4 μm), and the need for long tool life to support continuous, high-volume production. Tool wear, chipping, and poor chip evacuation due to high cutting temperatures are common issues, leading to frequent tool changes and reduced productivity. Additionally, maintaining consistent vertical wall accuracy during slotting and contouring is essential to prevent misalignment in assembly processes.
For semiconductor module plate finishing, milling tools must meet the following key performance criteria:
- High material removal rate (MRR): to reduce cycle time and increase throughput.
- Excellent surface finish: to ensure component compatibility and reliability in high-vacuum and cleanroom environments.
- Accurate vertical wall control: to maintain tight dimensional tolerances during slotting and profiling.
- Wear resistance and tool longevity: to minimize downtime and maintenance costs.
- Effective chip breaking: to avoid chip accumulation and tool jamming in deep cavity or thin-wall machining.
- Thermal stability: to withstand high-speed cutting conditions without deformation or premature wear.
SDF’s range of reversible indexable milling tools has been specifically engineered to meet the demanding requirements of this sector. The tools feature an advanced modular insert design with multiple cutting edges, allowing for high cutting efficiency and reduced tool change frequency. The optimized flute geometry ensures consistent chip evacuation and stable cutting forces, while the high-performance PVD coating enhances wear resistance and heat dissipation.
The inserts are manufactured using high-density carbide substrates and are designed for both roughing and finishing applications. The cutting edge geometry is tailored to minimize notch wear and edge chipping, particularly during interrupted cuts or high-feed machining. The tools are also equipped with a thermal barrier coating (TBC) that provides excellent protection against heat-induced wear and deformation, making them ideal for high-speed finishing of hardened materials.

A notable application involved a European semiconductor equipment manufacturer requiring high-precision finishing of hardened steel module plates (48 HRC) for vacuum chamber assembly. The customer faced issues with poor surface finish (Ra 0.5 – 0.6 μm) and frequent tool breakage, which led to high maintenance costs and long setup times.
SDF’s technical team conducted a comprehensive cutting condition analysis and recommended a reversible end mill with multi-notch geometry and high-performance PVD coating optimized for the specific material and cutting depth. The tool was tested in a controlled environment under high-speed conditions and demonstrated consistent performance without edge failure or chipping. Following successful trials, the customer integrated the SDF tool into their production line.
Post-implementation results were significant. The customer reported a 25% improvement in cutting speed, 30% increase in tool life, and a 15% reduction in surface roughness. Downtime associated with tool change was reduced by 40%, directly improving machine utilization and production output. These improvements were primarily attributed to SDF’s advanced insert design and superior coating technology.

| Cutting Speed (m/min) | 800 | 1,000 |
| Tool Life (m) | 12,000 | 15,600 |
| Surface Roughness (Ra, μm) | 0.5 – 0.6 | 0.3 – 0.4 |
| Downtime Reduction (%) | – | 40 |
