1325 1530 2030 2040 3030 U-Shaped Five-Axis EPS CNC processing center

YOUHAOCNC's next-generation "U"-shaped bed five-axis/four-axis double-swing CNC machining center. This machine addresses the "light, brittle, and bulky" characteristics of polypropylene (EPS/EPP/ETPU and other foam materials), featuring comprehensive optimizations from structure, swing head, systems, and process flow. This allows for efficient completion of core processes such as automotive molds, sports protective gear, aircraft models, and lost-foam casting with a single clamping setup.

YOUHAOCNC Polypropylene "U"-Shaped Bed: Large Travel, High Rigidity, and Zero Dead Angles

Traditional gantry or C-shaped structures are prone to overhang deformation when machining ultra-wide foam parts. Polypropylene's "U"-shaped, integral casting bed easily accommodates entire vehicle clay models or lost-foam foam blocks.

I. Industry Pain Points: Why "Specialized Polypropylene Machines" are Essential

1. Large Size and Low Density - Traditional gantries are prone to overhang vibration, resulting in tool marks on the bottom of the finished product. 2. High dust and static electricity—Ordinary tabletops lack sufficient adsorption capacity, resulting in a high rate of scrap caused by foam "flying" during machining.

3. Deep curves and sharp angles—Three-axis or simple four-axis machining requires multiple turnovers, resulting in low efficiency and large cumulative errors.

4. Soft materials with high springback—Common metal machining parameters are incompatible, leading to frequent tool edge gnawing and tool burning.

II. Polyron's Answer

1. "U"-Shaped Integral Casting Bed

• The worktable is sunken, with extended Z-axis travel, allowing for the entire model to be placed inside.

• The crossbeam's load points extend to both ends, increasing static rigidity and enabling high-speed cutting to achieve a mirror-like bottom surface finish.

2. Dual Swing Head Matrix

• 5-axis BC swing head: B ±120° / C ±320°, HQD 12 kW water-cooled electric spindle, 24,000 rpm, capable of single-shot forming of deep cavities and lateral undercuts;

• 4-axis A swing head: A ±90°, HQD 9 kW air-cooled electric spindle, enabling fast milling and cost-effective machining;

• 5-minute switching between 4th and 5th axes, achieving dual functionality in one machine.

3. Italian Eurosight System

• Eurosight OPEN Smart 5-axis, with RTC and Baohan 22-inch monitor:

4. Table and Clamping

• Standard: Thickened aluminum table with T-slots and pressure plates;

• Optional: Mild steel T-shaped plate table for increased wear resistance during high-frequency clamping;

• Optional vacuum zones for full-width suction to prevent foam shifting.

5. Independent Air Conditioning Control Cabinet

A D02 independent control cabinet is used, equipped with industrial air conditioning, and the sheet metal is galvanized.

III. What Materials Can One Machine Process?

• EPS (lost foam, building modules)

• EPP (car bumpers, child seats, airline containers)

• ETPU (popcorn shoe soles, sports protective gear)

• Wood substitutes, balsa wood, clay models

• EVA, PU foam, nylon, and other lightweight non-metallic materials

IV. Six Core Advantages: Transforming "Lightweight" into "High Profit"

1. Zero Turnover: Five-axis linkage enables single-step machining of deep cavities and undercuts, reducing auxiliary labor hours.

2. Zero Waste Edge: A U-shaped machine bed and specialized tools increase the yield of finished products.

3. Tool Savings: Dedicated foam cutters extend the life of individual cutters and reduce monthly consumable costs.

4. Maintenance Savings: An independent air conditioning cabinet and automatic lubrication reduce annual downtime.

V. Application Cases

• EPP cushioning layer for new energy vehicle battery casings: Five-axis BC oscillating head for single-step molding, improving efficiency.

• EPS core material for 60-meter wind turbine blades: Integrated U-shaped bed processing eliminates splicing stress.

• ETPU midsole for international sports brands: ±120° B-axis oscillation for machining lateral curved surfaces, eliminating manual trimming.

• Aerospace airfoil prototype: Arc accuracy of ±0.02 mm.
