02. Quality of Core Components:
- The quality of core components, particularly the servo motors and electrical parts, is crucial for machine stability during operation. AMOR CNC uses internationally recognized brands for all core electrical components: Mitsubishi servo motors from Japan, low-voltage electrical components from Schneider Electric in France, and Omron photoelectric limit switches from Japan. These ensure the stable operation of the electrical system.
03. Stable Bed Structure Design:
- A robust bed structure is vital. Look for a machine with an integrated welded bed that includes internal supports to prevent deformation during continuous use. The bed should also have sufficient weight to prevent vibration during fast cutting, which could affect processing accuracy. For instance, AMOR's 1600x2500mm bed weighs no less than 450 kg, ensuring stability during operation.
04. Precision Bed Processing Technology:
- The installation surfaces for the guide rails and racks on the bed should be machined using a precision five-axis machining center. This ensures flatness, accurate drilling, and tapping, providing a solid installation foundation for the machine’s components.
05. Reasonable Transmission Structure:
- The machine's transmission structure plays a critical role in precision. Common structures include belt drives and rack drives. For high-precision gasket cutting, AMOR uses high-precision ground racks combined with Taiwan HIWIN linear guides. Additionally, the X-axis features dual Mitsubishi servo motors paired with precision reducers, ensuring high-precision cutting.（Regarding the importance of transmission structure, please refer to:2 Different Gantry Motor Drive for Oscillating Knife Cutting Machines）
06. Enhanced Tool Holder:
- Standard tool holders, using a double-row parallel linear guide structure, are not ideal for long-term cutting of high-hardness materials like non-asbestos sheets and PTFE gaskets, due to potential gaps that lead to cutting errors. To address this, AMOR has developed an L-shaped reinforced tool holder with two HIWIN guides (20mm and 15mm wide), enhancing stability and enabling continuous, precise cutting of hard materials without gaps.
07. Effective Vacuum Adsorption System:
- AMOR equips its CNC gasket cutting machines with a powerful vacuum pump and a 16-hole vacuum adsorption table to securely hold hard, small gasket materials in place during cutting.
