Used Glass Drilling Machines

12345

Overview

Glass drilling machines are specialized tools for creating precise holes in flat or curved glass for hardware, fittings, or decorative work. They range from benchtop CNC units to large automated tables with water cooling and diamond tooling. These machines focus on spindle stability, coolant systems, and fixturing to prevent chipping or cracking, making them essential for glaziers, window manufacturers, and glass fabricators.

FAQ

What should I check when buying a used glass drilling machine?

Inspect spindle runout, motor condition, coolant pump, frame straightness, and control electronics. Ask for maintenance records and recent photos or video of the machine drilling typical parts.

How do I verify the condition of drill bits and spindle?

Check bit edges and diamond segments for wear, confirm proper concentricity, and run the spindle at working speeds to listen for vibration or noise. Request a cutting test on a scrap glass piece.

How should the machine be prepared and shipped?

Drain coolant, secure moving parts, remove fragile accessories, and pack the spindle and controls. Use a transport company experienced with industrial glass equipment and crate or palletize to prevent shocks and moisture.

What regular maintenance does a glass drilling machine need?

Maintain coolant cleanliness, inspect and replace worn tooling, check spindle bearings, clean filters, and verify stepper/servo calibration. Schedule preventive checks based on production hours.

Are spare parts and tooling easy to source?

Common spindles, pumps, seals, and diamond drill bits are widely available, but confirm model compatibility and lead times before purchase—especially for older or custom machines.
