Why This CNC Round Corner Machine
Six features that deliver precision CNC corner grinding on every glass sheet.
CNC 4-Corner Automatic Processing
The only machine in its class that processes all four corners of a rectangular glass sheet in one CNC program cycle. The PC-based controller calculates corner paths from glass dimensions, indexes between corners automatically, and maintains ±0.05mm accuracy at every radius.
R5–R120mm Adjustable Corner Radius
Continuous corner radius adjustment from R5mm (tight rounded corner for small glass) to R120mm (wide arc for large architectural panels). Radius set via CNC interface — no mechanical changeover required. Supports Pencil, Ogee, Waterfall, and Flat profiles.
3-Wheel Single-Pass Cycle
Each spindle holds 3 wheels — coarse diamond grind, fine diamond grind, and felt polish — all in one pass. The corner is ground and polished in a single cycle without wheel changes or manual intervention. Reduces processing time by 60% vs. single-wheel systems.
PC-Based CNC with G-code
Industrial PC controller with Windows-based touchscreen interface. Program corner profiles using G-code or graphical editor. Store up to 999 job presets. Real-time X/Y coordinate display with glass diagonal auto-detection.
Pneumatic Glass Clamping
Vacuum-assisted pneumatic clamping holds glass sheets flat and secure during corner grinding. Clamping force adjustable for different glass thicknesses (3–25mm). Quick-release for rapid glass loading and unloading.
Pencil / Ogee / Waterfall Profiles
Multiple edge profiles available per corner: Pencil (rounded), Ogee (S-curve), Ogee 2 (double S-curve), Waterfall (cascading), and Flat (straight chamfer). Switch between profiles via CNC interface — no mechanical reconfiguration.
CNC 4-Corner Automatic Processing
The only machine in its class that processes all four corners of a rectangular glass sheet in one CNC program cycle — ±0.05mm accuracy at every radius from R5 to R120mm.

How It Compares
CNC Round Corner vs. manual corner grinder vs. straight-line edger.
Hanwin CNC Round Corner Machine leads in Corner Precision (98) and Automation (95) — the most precise and automated corner grinding solution in its class.
حيث يتفوق
From shower glass to appliance panels — one machine, every corner need.
Shower Enclosures & Doors
Safe Rounded Corners
Shower glass panels require safe, rounded corners to prevent injury and ensure proper fitting within frames. The CNC Round Corner machine processes all four corners of shower panels in one cycle, with R10–R25mm pencil or ogee profiles that meet building safety codes.

Five essential maintenance practices to maximize corner accuracy and wheel life.
Inspect all 3 wheels per spindle (coarse, fine, polish) for loading, glazing, or uneven wear. Dress or replace wheels as needed. Check coolant flow rate and concentration. Clean wheel surfaces with clean water at end of shift. Verify pneumatic clamping pressure.
Run the CNC calibration routine to verify corner radius accuracy at R10, R30, R60, and R100mm test positions. If accuracy drifts beyond ±0.1mm, recalibrate the X/Y positioning system. Update CNC offset values. Backup all job presets.
Inspect all pneumatic cylinders, valves, and tubing for leaks. Lubricate pneumatic guide rails. Replace air filter elements. Check compressed air pressure regulator settings. Verify clamping force is consistent across all contact points.
Inspect spindle bearings for play or noise. Check spindle alignment and runout using a precision dial indicator. Verify motor power output. Lubricate all linear guides and ball screws. Check CNC controller software version.
Perform complete machine calibration using laser measurement tools. Verify corner radius, corner accuracy, X/Y positioning, glass diagonal detection, and pneumatic pressure. Replace grinding wheels, polishing wheels, and wear components. Full safety system test and CE compliance check.
الأسئلة الشائعة
Everything you need to know about the CNC Round Corner Grinding Machine.
The minimum corner radius is R5mm on all models. This tight radius is suitable for small glass pieces and precision applications. The maximum ranges from R100mm (A1/A2 models) to R120mm (B model) — the widest radius range in its class.
Yes — the G-CGC-A1 and A2 models process all four corners of a rectangular glass sheet in one CNC program cycle. The controller calculates corner paths from the glass dimensions and diagonal, then indexes between corners automatically. The B model processes one corner at a time.
Five edge profiles are available: Pencil (fully rounded), Ogee (S-curve), Ogee 2 (double S-curve), Waterfall (cascading), and Flat (straight chamfer). Switch between profiles via the CNC touchscreen interface — no mechanical reconfiguration required.
Standard glass diagonal range is 400–1500mm. Maximum glass size is 1300×2500mm. Larger glass sizes are available on request. The pneumatic clamping system adjusts to hold glass securely from minimum to maximum size.
The CNC-controlled system delivers ±0.05mm corner accuracy across the full radius range (R5–R120mm). The PC-based controller uses real-time X/Y coordinate tracking and G-code path interpolation to maintain consistent radius geometry.
The A1 processes 1 corner at a time with 3 wheels and PLC control. The A2 processes 2 corners simultaneously with 2 spindles (6 wheels total) and ABB motors — ideal for high-volume production. The B model is semi-automatic with the widest corner radius range (R120mm) and most compact footprint.
