Solution Overview
Problem
Diamond wire machines for cutting natural or artificial stone face limitations in cutting speed and efficiency due to heat generation, excessive diamond consumption, and inefficient swarf removal, which affects performance and cleanliness, leading to reduced cutting precision and increased maintenance needs.
Innovation Solution
A diamond wire machine with multiple closed-loop wires and a comprehensive cleaning system featuring multiple washing areas with high-pressure elliptical nozzles and a filtration and pump assembly to efficiently remove swarf and recirculate cleaning water, optimizing cutting speed and reducing diamond consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the advancing speed of the diamond wire is increased to improve cutting efficiency, then productivity increases, but heat generation increases causing excessive diamond consumption
Solution Approach 1:
The patent applies preliminary cooling action by spraying water onto the diamond wire before it enters the cutting zone and continuously during cutting. This pre-cooling prevents excessive heat buildup that would otherwise cause diamond detachment and consumption, allowing higher advancing speeds without increasing diamond loss
Solution Approach 2:
Water acts as an intermediary substance between the diamond wire and the stone block. It serves dual functions: cooling the wire to prevent diamond detachment and flushing away swarf. This intermediary enables sustained high-speed cutting by managing heat and debris removal
2Productivity
If multiple diamond wires are used simultaneously to increase productivity, then cutting speed improves, but swarf accumulation increases affecting wire cleanliness
Solution Approach 1:
The patent extracts swarf from the cutting zone by implementing a water flow system that flushes removed material away from the diamond wires. The water current actively removes swarf that would otherwise accumulate on the wires, maintaining cleanliness even when multiple wires operate simultaneously
Solution Approach 2:
The patent uses hydraulic action through water spray and flow to clean the diamond wires. High-pressure water jets and continuous water flow remove swarf accumulation, preventing the reliability issues that would result from dirty wires in multi-wire cutting operations
3Loss of substance
If cooling water is sprayed into the cuts to remove swarf, then swarf removal improves, but heat generation limits the cutting speed
Solution Approach 1:
The patent applies preliminary cooling before significant heat buildup occurs by positioning water spray nozzles to cool the diamond wire and cutting zone in advance. This proactive cooling allows faster cutting speeds without exceeding thermal limits that would hinder swarf removal

AI summary
A diamond wire machine for cutting natural or artificial stone, comprising: water distribution system (12) for cooling within the cut made by the diamond wire in the stone; at least one closed loop diamond wire (3) which, following a closed line of movement, repeats the cut during its movement deeper in to the stone; rotating organs (4, 5) for the support, motorization and tension of the diamond wire; it presents a further cleaning system for the diamond wire with at least one washing area (13) immediately after the cut and before, during the run of the wire, in relation to the first organ of support and motorization (4) of the said wire, which the wire comes into contact with after the cut; the cleaning system comprising a filtration and pump assembly (19) for the recirculation of water that supplies the washing area at high pressure. Forms of construction are described with more cleaning areas than the cleaning areas said above and the filtration and pump assembly for the recirculation of cleaning water.
