Frequently Asked Questions (FAQ)
Q1: Can this machine clean all types of UPVC profiles?
A: Yes. The CNC system can be programmed for any PVC/UPVC profile shape—casement, sliding, tilt-and-turn, and more. It handles white, colored, co-extruded, and laminated profiles with appropriate cutter paths to avoid surface damage.
Q2: How long does it take to clean one window corner?
A: Cycle time is approximately 25–40 seconds per corner, depending on profile complexity and the number of surfaces to clean. This is significantly faster than manual grinding and delivers superior consistency.
Q3: Is the machine difficult to program for new profiles?
A: Not at all. The touchscreen interface is intuitive. Operators can manually teach new profiles by moving the cutter to key points, and the system automatically generates the cleaning path. Saved programs can be recalled instantly for repeat orders.
Q4: What maintenance is required?
A: Routine maintenance includes periodic lubrication of guide rails, checking pneumatic connections, and replacing cutter blades. We provide a maintenance schedule and spare parts list. Most wearing parts are standard and readily available.
Q5: Do you provide installation and training?
A: Yes. We supply a full English manual, instructional video, and remote training via video call. On-site installation and training can be arranged for large orders or production lines.
