Precision Machining Case for Food & Beverage Filling Line Components

【Project Background】

This project involved a set of customized precision components for a food and beverage filling line. The parts were used in the conveying, positioning and filling sections of the equipment, including stainless steel mounting plates, guide blocks, support brackets and positioning shafts. Since the equipment was designed for continuous production, the components needed to meet requirements for dimensional accuracy, corrosion resistance, easy cleaning and long-term operating stability.

The customer provided 3D models, 2D drawings and assembly requirements. Most parts were made from stainless steel materials, while several positioning and support components required CNC finishing after initial machining. The project required stable batch consistency because the parts would be assembled into multiple filling line stations. Any dimensional deviation could affect bottle positioning, filling accuracy or equipment running smoothness.

【Machining Challenges】

The first challenge was controlling the machining quality of stainless steel. Stainless steel has relatively high toughness and can generate heat during cutting, which may lead to tool wear, burrs or surface scratches if the cutting parameters are not properly selected. For parts used in food and beverage equipment, surface quality is especially important because rough surfaces or sharp edges can affect cleaning performance and equipment hygiene.

The second challenge was maintaining batch consistency across different parts. The filling line included multiple stations, and each station required stable positioning accuracy. If mounting holes, guide surfaces or shaft dimensions varied between parts, it could cause assembly difficulties or inconsistent operation during production.

Another challenge was balancing machining efficiency and quality control. The customer required a short delivery cycle, but the parts still needed strict inspection before shipment. Key dimensions such as mounting hole positions, guide slot width and shaft diameter had to remain within the drawing requirements.

【Process Solution】

Qingdao SCreate Industrial Technology Co., Ltd. developed a machining process based on the part structure, material characteristics and assembly requirements. Before production, the engineering team reviewed all drawings and classified the parts according to material, tolerance level and functional position in the filling line.

For stainless steel plates and brackets, CNC milling was used to process mounting surfaces, holes and guide slots. Cutting tools and machining parameters were selected to reduce heat accumulation and improve surface finish. For positioning shafts and cylindrical parts, turning and finishing processes were combined to control diameter accuracy and surface smoothness.

During machining, important parts were inspected in process to prevent batch errors. Key holes and guide features were processed according to unified datums to ensure stable assembly relationships. After machining, all sharp edges were chamfered and deburred. The surfaces were cleaned before final inspection to make sure the parts were suitable for use in food and beverage equipment.

【Quality Results】

After production, the quality team inspected the key dimensions, hole positions, guide slots, shaft diameters and surface condition. The inspection results showed that all critical dimensions met the customer’s drawing requirements, and the batch parts maintained stable consistency.

During customer assembly verification, the components were installed smoothly into the filling line stations. The guide blocks and positioning shafts operated stably, and the stainless steel mounting parts showed good surface quality without obvious burrs, scratches or sharp edges. The customer confirmed that the parts met the requirements for equipment assembly and trial production.

Through this project, SCreate demonstrated its capability in precision machining of stainless steel components for food and beverage automation equipment. The project also provided reliable experience for future batch production of filling line, conveying system and packaging equipment components.
