| How FORESEEN OPTICS Improves Material Utilization: Key Cost Control Measures in Rifle Scope Component Machining


Precision machining is like a sculptor carving a beautiful piece of jade—our goal is to retain as much of the jade in the final product as possible, rather than turning it into waste. This is the shared direction of our machining and structural design efforts. In the manufacturing of rifle scopes, FORESEEN OPTICS optimizes part geometry, selects appropriate materials, and arranges machining processes to maximize material utilization and production efficiency. Below, we detail our strategies in rifle scope production from three key aspects: geometry optimization, material selection, and process adjustment.

  1. Geometry Optimization
Geometry Optimization

FORESEEN OPTICS optimizes the geometry of rifle scope components during machining to increase material utilization. We balance the functional requirements of each rifle scope part with the material removal needed, reducing unnecessary cavity cutting while maintaining the strength and stability of the components.

Equipment Utilization and Cavity Optimization: For different geometries, we choose the most suitable equipment for rifle scope part machining. For parts that require significant hollowing, we use multi-axis machining centers to achieve complex shapes in as few steps as possible. For simpler cavity shapes, we use more economical equipment to reduce machining time and costs.

Collaboration in Structural Design: During the design phase of rifle scopes, our engineers work closely with the machining team to ensure the part geometry is optimized for material conservation during processing, and to avoid unnecessary complexity that could increase material removal.

  1. Aluminum Bar/Tube Material Selection
Aluminum Bar-Tube Material Selection


In material selection, FORESEEN OPTICS pays careful attention to the choice between aluminum bars and tubes for rifle scopes to ensure the best balance of material utilization and cost-effectiveness.

Bar vs. Tube Selection: Depending on the specific shape and functional requirements of rifle scope parts, we choose either aluminum bars or tubes. For parts with thin walls and significant hollow structures, tubes are preferred to minimize material removal. For components requiring higher structural strength, bars are selected, but their diameter is optimized to minimize unnecessary material removal during machining.

Reducing Material Removal: When selecting material specifications, we aim for dimensions that are close to the finished rifle scope component size, minimizing unnecessary cutting and scrap. This approach reduces material waste and machining time, ultimately lowering overall costs while maintaining the quality of the rifle scope.

  1. Process Adjustment
Process Adjustment

Process adjustment is key to achieving efficient machining and reducing the production cost of rifle scopes. FORESEEN OPTICS optimizes the sequence of turning and milling operations to ensure each step achieves the most efficient material removal and best surface quality.

Order of Operations: Turning vs. Milling

In the machining of rifle scope parts, we determine whether to turn or mill first based on the characteristics of each component. For parts requiring precise external profiles, turning is often performed first to create the base shape, followed by milling to handle more complex details, ensuring accuracy and minimizing the risk of re-positioning errors. For flat structures requiring extensive milling, milling is prioritized to quickly remove excess material.

Machining Path and Strategy Adjustment: Using advanced programming software, we meticulously plan the machining path for rifle scope parts, reducing non-productive tool movements and shortening tool paths to decrease machining time. Additionally, by using specialized fixtures during process transitions, we minimize the time needed for re-clamping and re-positioning, thus improving the efficiency of rifle scope machining.

Through these measures, FORESEEN OPTICS ensures that each piece of material used in rifle scope production is maximized, while also reducing machining time and waste. This detailed approach to machining and structural design not only boosts the production efficiency of our rifle scopes but also helps us produce high-quality products at a lower cost.

We use advanced CNC lens processing technology to machine glass blanks directly into standard pre-formed lenses, ready for polishing. During the polishing phase, we use various polishing processes to ensure the smoothness of the lens surface.

By selecting the appropriate polishing process according to lens type and aperture requirements, we can shorten polishing time and maintain a high-quality finish. This optimized strategy not only speeds up lens production but also ensures the optical quality necessary for the performance of the final product.
