Selection Guide for Slitting Machine Gearboxes! Different materials require different models—wrong choice means wasted equipment

The following is a selection guide that combines the characteristics of different materials with the core parameters of the reducer to help you accurately match.

1、 Step 1: Determine accuracy and transmission scheme based on material characteristics

The thickness, hardness, and toughness of the material directly determine the core requirements for the cutting machine transmission system.

1. Ultra thin material (<0.05mm)

Common materials for ultra-thin materials include high-end capacitor films, gold and silver foils, photosensitive adhesive films, ultra-thin plastic films, etc.

Core requirements for ultra-thin materials: extreme precision and stability, preventing material stretching, wrinkling, or shaking.

Suggestions for selecting ultra-thin materials:

Ultra thin material transmission scheme: It is necessary to use servo motor direct drive to avoid accuracy loss caused by gear backlash.

Ultra thin material reducer type: If a reducer is needed, a high-precision planetary reducer or RV reducer should be selected, and the return clearance (backlash) should be extremely small (such as ≤ 1 arc minute) to ensure high-precision rotation and positioning at any angle.

Supporting system: It needs to be equipped with a fully closed-loop tension control system and a high-precision correction system (EPC).

2. Conventional film and paper (0.05mm-1.0mm)

Common materials for conventional films include ordinary plastic films (PE, PP, PET), copper aluminum foil, paper, non-woven fabrics, thin metal sheets, etc.

The core requirement for conventional thin films is to achieve a balance between accuracy, efficiency, and versatility.

Suggestions for selecting conventional thin films:

Conventional thin film transmission scheme: A servo direct drive system or a composite scheme of belt transmission and gear reduction can be selected.

Conventional thin film reducer types:

High precision requirements: Choose a planetary gearbox, which has a compact structure, high transmission efficiency (over 95%), and small backlash, suitable for precision cutting.

Universal/cost priority: using gear reducers, durable and affordable, suitable for conventional slitting with less extreme precision requirements.

3. Thick plates and rigid materials (>1.0mm)

Common materials: corrugated cardboard, sponge, fiberboard, acrylic board, thick metal foil, etc.

Core requirements: Strong cutting force and high rigidity to cope with the huge resistance during cutting.

Selection suggestion:

Transmission scheme: Priority is given to hydraulic drive systems, which can generate cutting forces of over 10 tons and are designed specifically for ultra thick materials.

Gearbox type: If using a motor-driven gearbox, it is necessary to choose a gearbox with high torque and high rigidity, such as an RV gearbox, which is very suitable for such heavy-duty conditions due to its impact resistance and high rigidity. At the same time, the motor power needs to be increased accordingly (possibly requiring 11-15kW or higher).
