Prism Cutting Machine

Die SGR 20 is a specialized Diamantdrahtsäge designed for cutting optical glass and ceramic prisms with high precision. Equipped with a programmable rotary worktable, the system can rotate the workpiece to specified angles for multi-faceted slicing—making it ideal for producing triangular, quadrilateral, pentagonal, and polygonal prism blanks.

KEY FEATURES

1. Multi-Angle Prism Cutting Functionality
The rotary worktable can rotate 360°, allowing users to set precise prism angles. The system supports automated generation of triangles, squares, pentagons, octagons, and more—ideal for producing optical prism blanks.
2. Automatic Slicing Capability
Operators can program different slicing thicknesses within a single job. Once the thickness and quantity are set, the machine automatically performs the full slicing sequence without supervision.
3. Stable Vertical Structure with Enclosure
The SGR 40 uses a fully enclosed upright design with a steel frame and observation window, providing both safety and easy visual monitoring during the cutting process.
4. Servo-Driven YZ Motion with Ball Screws
The slicing axes (Y and Z) use servo motors, linear guides, and ball screws for precise positioning—repeatability up to ±0,01 mm and feed resolution of 0.01 mm.
5. Touchscreen + Manual Control Interface
A user-friendly English-language PLC system enables parameter setup via touchscreen, with a handheld controller for easy manual alignment and override.
6. Integrated Water Cooling & Lubrication
Equipped with a water circulation system und automatic oil lubrication to ensure a clean, stable cutting environment.

EuroPhotonics

The SGR 20 has significantly improved our prism production process. We used to rely on manual setups for each cut, but now we can slice three or four surfaces in one program without re-clamping. The angle accuracy is excellent, and the surface finish is good enough to go straight to polishing. It’s stable, user-friendly, and has become a key machine in our optical fabrication line.

Häufig gestellte Fragen

Welche maximale Dicke kann die Maschine beim Schneiden verarbeiten?

The machine is capable of cutting slices ranging from 0.1 to 100 mm in thickness, and can perform automated cutting once the program has been configured.

Was ist der Unterschied zwischen dieser Seilsäge und der BANDSÄGE?

Die Schnittgeschwindigkeit wäre ähnlich, aber die Schnittflächenqualität der Seilsäge ist viel besser und der Schnittfugenverlust ist geringer.

Wie minimiert die Maschine den Materialabfall beim Schneiden?

Der HorizonCrystal verfügt über einen hochpräzisen Diamantdraht mit einem Durchmesser von 0,35 bis 0,8 mm, so dass die Schnittfuge sehr klein ist.

Wie hoch ist die erwartete Lebensdauer des Diamantseils, und ist es vom Benutzer austauschbar?

Die Lebensdauer des Diamantseils variiert je nach Verwendung und Materialhärte. Für Graphit kann 1 Stück Schneidedraht etwa 15 Quadratmeter schneiden. es ist vom Benutzer austauschbar, und wir bieten eine detaillierte Anleitung zum Austausch des Drahtes.

Benötigt die Maschine eine spezielle Umgebung oder besondere Einstellungsbedingungen?

Für das Schneiden von Graphit hat der Kunde normalerweise eine Staubabsaugung. Es kann mit unserer Maschine verbunden werden, wenn es läuft.

Welche Art von technischer Unterstützung und Garantie bieten Sie mit dem Kauf dieses Geräts?

Wir bieten eine umfassende Garantie für 1 Jahr und technischen Support per Video oder vor Ort nach dem Kauf, um sicherzustellen, dass Ihre Maschine mit maximaler Effizienz arbeitet und alle Probleme umgehend gelöst werden.
