Technical Consultant for High-Frequency CNC Impact Etching on Glass ("Knacking")
Budget: €30 – €250 EUR
Project Overview: I am establishing a production line for large-format glass art (approx. size A2). The technique involves creating images via thousands of micro-impacts ("stippling" or "knacking") on 8mm float/tempered glass. I need an expert to validate my machine choice or propose a better industrial alternative.
The Challenge: I am currently evaluating the Gravotech IS900 series, but I have concerns regarding the Z-axis speed. Standard engraving speeds are too slow for images requiring >100,000 dots. I need a setup capable of High-Frequency Impact (Vibro-Peen/Solenoid) to achieve a cycle time of under 30 minutes per A2 panel, without shattering the glass.
What I need from you: This is a purely consultative role. I do not need you to build the machine, but to engineer the decision.
Feasibility Check: A frank assessment of whether a standard CNC router (like Gravotech) with a solenoid attachment is the right path, or if I should look at dedicated Dot-Peen integrators (e.g., Technomark, Sic Marking, Pryor).
Machine Comparison: A written comparison of the top 3 viable setups (Brand/Model) that offer:
Large flatbed area (>A2).
High-frequency solenoid or pneumatic heads (>100Hz preferred).
Precise force control (to create a "white" pixel without causing deep structural cracks).
Technical Roadmap: Advice on the controller/software workflow. How do we feed a raster image (JPG/BMP) to a dot-peen controller efficiently? (Raster-to-Gcode vs. Proprietary software).
Q&A Call: A 30-minute video call to discuss tooling (diamond vs. carbide) and maintenance.
Required Expertise:
Deep knowledge of CNC, Dot-Peen, or Impact Marking technologies.
Understanding of brittle material processing (Glass/Ceramics) is a huge plus.
Manufacturer-agnostic (I need the best tool, not just the most famous one).
To apply: Please tell me briefly about your experience with high-speed marking or glass processing. Mention one machine brand other than Gravotech that I should investigate.
