Workpiece Literacy: Uses, Materials/Geometric Characteristics, and Common Risks of Worms

The worm is a core component of mechanical transmission systems, widely used in reducers, elevators, machine tools, construction machinery, and other fields. It plays a key role in transmitting torque, reducing speed, and increasing torque. Its materials are mostly 45 steel, 20CrMnTi, superalloys (such as Inconel 718), etc. Its geometric characteristics are complex helical tooth profiles, high lead accuracy requirements, and strict tooth surface roughness. Common risks in manual processing include: excessive tooth profile deviation leading to high transmission noise, substandard surface roughness causing accelerated wear, and unstable dimensions resulting in assembly failures, which seriously affect the operating efficiency and service life of equipment.

Core pain point: The impact of processing difficulties on efficiency/cost/quality

Traditional manual whirlwind milling has three core pain points:

① Insufficient precision: relying on manual operation experience, it is difficult to control the tooth profile tolerance within ±0.02mm, and the rejection rate is as high as over 15%, which directly increases the cost of raw material waste;

② Low efficiency: processing a single worm takes 2-3 hours, which cannot meet the demand for large-volume orders, leading to customer loss;

③ High cost: the price of imported CNC whirlwind milling machines exceeds one million yuan, and the maintenance cost accounts for 10% of the total equipment price per year, which is difficult for small and medium-sized manufacturing enterprises to afford. These pain points not only restrict the improvement of production capacity, but also weaken the competitiveness of enterprises in the market.

Overview of the Process Flow

The UBS50-1000 whirlwind milling machine adopts fully automated process control of the entire workflow: “blank → rough machining → finish machining → surface treatment → closed-loop inspection”:

Blank: Forgings/castings are selected (customized according to material properties) to ensure initial strength and dimensional stability;
Rough machining: CNC whirlwind milling quickly removes the allowance, increasing efficiency by 2 times;
Finish machining: Five-axis linkage precisely controls the tooth profile to ensure tolerances and surface quality;
Surface treatment: Automated polishing/coating processes to enhance wear resistance;
Closed-loop inspection: The online measurement system feeds back data in real time and automatically adjusts parameters to achieve zero-defect quality.

Key points of each link

Rough machining: Using cemented carbide coated tools (internal link: XXX tool system), with a spindle speed of 1500-2500rpm and a feed rate of 200-300mm/min, 80% of the allowance is quickly removed, and temperature deformation is controlled through the cooling system;
• Finishing: The five-axis CNC system (internal link: XXX five-axis linkage technology) is combined with CAM-optimized tool paths, controlling the tooth profile tolerance within ±0.01mm and the surface roughness Ra ≤ 0.8μm;
• Surface treatment: Automated polishing equipment (internal link: XXX polishing system) removes machining marks, and optional PVD coating increases tool life by 3 times;
• Inspection closed-loop: Online coordinate measuring machine (internal link: XXX inspection system) collects dimensional data in real-time, and digital twin technology simulates the machining process to avoid deformation risks in advance.

Case+Application Scenario

Case Study: A construction machinery enterprise originally used imported whirlwind milling machines, with a processing cost of CNY 800 per worm and a delivery lead time of 5 days. After adopting the UBS50-1000, the processing cost was reduced to CNY 350 per worm, and the delivery lead time was shortened to 2 days, enabling the enterprise to recoup the equipment investment within six months.

Applicable Scenarios: Reducer manufacturing, elevator core component production, machine tool transmission system processing, and supporting hydraulic devices for construction machinery.
