Vertical Contour Cutting Machine
The SVI 50-40 is a vertical structured diamond wire cutting machine designed for high-precision cutting of medium to large-sized brittle materials, including quartz glass, technical ceramics, sapphire, and composites. This versatile model supports multiple cutting functions, including straight slicing, irregular profile contouring, and internal shape cutting—all in a single setup.
Key Features of SVI 50-40
Multi-Functional Cutting Capabilities
SVI 50-40 integrates three cutting modes: straight slicing, irregular contour cutting, and internal cavity shaping. This makes it ideal for applications involving both standard geometry and complex profiles, eliminating the need for multiple machines.- Vertical Semi-Enclosed Structure
Its upright cutting orientation is paired with a semi-enclosed body design, offering clear visibility into the working area while enhancing safety. The structure allows for easy loading/unloading and improves operator access during setup and monitoring. - Excellent Coolant & Chip Evacuation
The vertical layout allows gravity to assist in coolant drainage and debris removal. This natural flow helps prevent swarf buildup, reduces cutting heat, and maintains wire sharpness for longer, resulting in a cleaner cut surface. - High-Precision Motion System
Driven by a stepper motor and supported by a precision ball screw system, the machine achieves positioning accuracy of ±0.015 mm and surface flatness of ≤0.03 mm. This ensures dimensional control even on brittle or layered materials. - Pneumatic Wire Tension System
Equipped with an adjustable pneumatic tension unit, the system maintains consistent wire tension throughout the cutting cycle. This reduces vibration, prevents wire slippage, and ensures smooth movement across complex geometries. - Dedicated Control System for Straight & Irregular Cutting
The machine includes a dual-mode cutting system that supports automatic straight slicing as well as custom programmed paths for profile and inner contour cutting. Operators can switch between modes with ease via a touchscreen interface. Industrial Electrical Integration
The SHVI 50-40 is equipped with a 2.2 kW main motor and high-quality electrical components compliant with industrial standards. The control box is well-organized and supports reliable long-term operation under continuous use conditions.

Frequently Asked Questions
What is the maximum thickness the machine can handle for cutting?
What is the difference between this wire saw and BAND SAW?
The cutting speed would be similar, but wire saw’s cut surface quality is far more better. and the kerf loss is smaller.
