The HX12070LNC is a Sand Wire Cutting machine in the Prominer CNC Endless Wire Saw Machine family. Endless (loop) wire saws run a continuous diamond- or abrasive-coated wire at high speed, delivering the thinnest kerf and finest surface finish of any wire-cutting method. Covering sand-wire, abrasive-wire and diamond-wire configurations across the HX, HXB, HXV, HXW, HXWB, HXVB, HXT and HXWV series, the Endless family handles everything from silicon ingot cropping to sapphire substrate slicing and large-format graphite blocks.
Continuous one-way cut
Eliminates reverse marks and boosts throughput vs reciprocating designs.
Minimal kerf & finish
Kerf as low as 0.2 mm; surface roughness <1 um, often no post-polish.
Multi-wire media
Configurable for sand / abrasive / diamond wire and wet or dry (HXWV) cutting.
Servo tension control
Load-cell feedback keeps wire tension steady for consistent results.

Support & Service
After-Sales Service
Every Prominer CNC diamond wire saw is backed by a 12-month standard warranty covering the machine frame, drive system, and CNC control unit against manufacturing defects. Extended warranty and annual service contracts are available on request.
Our technical team provides remote diagnostics within 24 hours of a reported issue and dispatches field engineers for on-site intervention in major markets. All machines ship with detailed acceptance test reports and spare-parts lists.
A lifetime supply of genuine wear components and consumables — guide wheels, wire-transport assemblies, tensioning systems, and cutting wire — is stocked at regional warehouses to keep your line running with minimal downtime.
Free firmware and control-system upgrades are included for the first two years, ensuring your equipment keeps pace with the latest slicing recipes and safety standards.
Installation & Training
Installation and commissioning are performed by certified Prominer CNC engineers, including machine leveling, axis alignment, and a full dry-run acceptance test against the agreed tolerances before sign-off.
Operator training covers safe operation, wire threading, tension setting, feed-rate optimization, and basic troubleshooting. Maintenance training covers lubrication points, guide-wheel replacement, and preventive maintenance schedules.
Training materials — operation manuals, video guides, and a illustrated spare-parts catalog — are delivered in digital form at handover, with optional on-site refresher sessions for new staff.
Operating Environment & Safety
Install the machine in a clean, level workshop with an ambient temperature of 5–40 °C and relative humidity below 85%. Avoid direct sunlight and corrosive atmospheres.
A stable three-phase power supply and a dedicated coolant / cutting-fluid circulation and filtration system are required. The working zone must be equipped with dust extraction (recommended port ≥ Φ100 mm) and adequate lighting.
Operators must wear protective eyewear and cut-resistant gloves. Loose clothing, ties, and jewelry are prohibited near the moving wire. Emergency stop buttons must remain unobstructed at all times.
