PT Industry Background and Machining Challenges:
In the field of industrial camera bracket manufacturing, precision is paramount due to the requirement for high stiffness-to-weight ratio and vibration resistance. These brackets are typically produced from high-grade stainless steel (e.g., SUS 303, 304, or 420) to ensure corrosion resistance and long-term durability. The key machining operation involves slot milling to form the mounting grooves and support rails essential for camera integration and alignment.
The typical process involves:
- Blank preparation (forged or cast stainless steel parts)
- Slot milling with end mills to create high-accuracy grooves
- Secondary finishing operations such as deburring and surface treatment
However, this process is not without challenges. Stainless steel is known for its high hardness and work-hardening tendency, which accelerates tool wear and shortens tool life. Additionally, the requirement for surface finish quality (Ra < 1.6μm) increases the difficulty of achieving consistent cutting performance. The narrow grooves and high depth-to-width ratios in slot milling also make chip evacuation and heat dissipation critical to avoid tool breakage and machining errors.
Technical Requirements for End Mills in this Industry:
For slot milling in industrial camera brackets, the end mill must meet the following key performance criteria:
- Specialized Coating: Must be tailored for stainless steel to minimize friction and adhesion.
- Thermal Stability: High-performance at elevated temperatures due to the high thermal conductivity of the material.
- Wear Resistance: Extended tool life is essential to reduce downtime and maintenance costs.
- Chip Control: Effective chip breaking and evacuation to prevent re-cutting and tool damage.
- Edge Stability: Resistant to chipping and edge wear under high-pressure cutting conditions.
SDF’s Product Solution:
SDF’s stainless steel end mills are engineered to deliver superior performance in complex slot milling operations. The key design features include:
- Optimized Geometry: A high helix design with variable pitch improves cutting smoothness and reduces harmonics.
- Advanced Coating: Our proprietary TiAlCrN coating enhances wear resistance and thermal stability while reducing friction.
- Material Selection: Substrate made from high-performance PM (powder metallurgy) carbide ensures excellent toughness and resistance to edge deformation.
Below is a comparison of SDF end mills with a leading international brand in key performance indicators:
| Parameter | SDF End Mill | Competitor’s End Mill |
|---|---|---|
| الطلاء | TiAlCrN (high-performance for stainless steel) | TiN + AlTiN (standard multi-purpose coating) |
| Helix Angle | 45° with variable pitch | 35° with uniform pitch |
| Tool Life (Hours) | 120 | 85 |
| Surface Finish (Ra) | 1.3μm | 1.8μm |
| Chip Breaking Performance | Excellent (no re-cutting observed) | Good (occasional chip re-cutting) |
Typical Customer Application Case:
A European industrial camera manufacturer faced challenges in slot milling high-precision grooves for a new bracket model. The grooves were narrow (2 mm width) and deep (8 mm depth), machined from SUS 303 stainless steel. The original tooling provided poor surface finish, frequent tool breakage, and low production throughput.
SDF’s technical team conducted a detailed analysis of the customer’s setup and proposed a customized end mill solution with a modified flute design and optimized cutting parameters. After several rounds of testing and tool trials, the new end mills were integrated into the production line.
The results after deployment were as follows:
| متري | Before SDF Implementation | After SDF Implementation |
|---|---|---|
| Cutting Speed (m/min) | 80 | 105 |
| Surface Finish (Ra) | 2.0μm | 1.4μm |
| Tool Life (hours) | 50 | 110 |
| Defect Rate | 5.2% | 1.1% |
| Production Throughput (pieces/hour) | 28 | 41 |
