The largest and most powerful machine in the Vimfun SOM lineup. Four-axis dual-board configuration cuts two workpieces up to 1000mm simultaneously — purpose-built for customers who need to move maximum material volume through a single machine type. When unit economics at scale is the primary objective, the SOM4-1000D is the answer.
The SOM4-1000D is the single most productive wire saw Vimfun manufactures. Three numbers define why high-volume producers choose it over running multiple smaller machines.
Two 1000mm workpieces cut simultaneously in one machine cycle. One operator, one footprint, double the output of a single-station machine.
1.5–25mm covers every production scenario from precision wafer slicing to coarse block squaring — no secondary machine required for thick cuts.
85kW main motor sustains consistent wire tension and feed rate across both 1000mm boards throughout long production runs without power degradation.

The SOM4-1000D is not for every customer — it is purpose-built for operations where volume throughput is the top priority. These are the four customer profiles that benefit most.
Operations running multiple shifts per day on a single material type — silicon ingots for solar cells, or large NdFeB sintered blocks for EV traction motor magnets. The SOM4-1000D maximizes slices-per-shift per machine, directly lowering unit cost of production.
When the workpiece exceeds 750mm or the width reaches 200mm, no other model in the SOM series can accommodate it. The SOM4-1000D is the only option for customers working with exceptionally large silicon bricks, oversized NdFeB blocks, or wide ceramic slabs.
Plants running three or four smaller wire saws to meet throughput targets can often consolidate to one or two SOM4-1000D units. This reduces operator headcount, simplifies maintenance scheduling, and frees up factory floor space for other equipment.
Companies building a new slicing line from scratch who want to design for maximum future capacity from day one. A single SOM4-1000D anchors a high-throughput line that can grow with demand, avoiding the cost of replacing smaller machines as volume scales.
For high-volume operations, the right machine choice is an economics decision. The table below illustrates how the SOM4-1000D's scale advantage compounds over a production shift. Values are indicative — actual figures depend on material and slice parameters.

Running one SOM4-1000D instead of two smaller machines means one maintenance schedule, one spare parts inventory, one operator assignment, and one set of process parameters to manage. Operational simplicity at scale is a real competitive advantage.
Built in-house at our Shanghai facility with direct engineering access. For a machine at this scale, direct manufacturer support — not dealer support — is what keeps large-format production lines running.
The SOM4-1000D's 2900 × 2300mm footprint requires proper site planning. Vimfun engineers conduct a pre-delivery site survey, provide foundation and utility requirements, and manage on-site installation and commissioning end-to-end.
At this production scale, wire supply consistency matters. Vimfun offers long-term supply agreements for diamond wire matched to SOM4-1000D specifications — securing your wire cost and quality for the machine's production lifetime.
The SOM4-1000D has a footprint of 2900 × 2300 × 2600mm and requires a reinforced foundation rated for the machine's operating load. Electrical supply must support the 85kW main motor peak draw, plus auxiliary systems. Vimfun provides a complete site preparation specification document and conducts a pre-delivery site survey as part of the purchase process.
For many customers, yes — but it depends on workpiece dimensions and slice parameters. The SOM4-1000D's dual 1000mm boards give it significantly more material throughput per cycle than two SOM4-630D units running 630mm boards. We recommend requesting a production analysis with your specific workpiece size, slice thickness, and daily volume target so we can provide a data-backed comparison before you make a decision.
The SOM4-1000D's larger groove wheels and more powerful motor system support a wider wire pitch, enabling cuts up to 25mm thick. This makes it the only SOM model capable of producing very thick wafers or structural slabs in a single wire-saw pass — relevant for customers producing thick silicon or ceramic substrate stock rather than standard wafer thicknesses.
Standard lead time is 90–120 days from order confirmation due to the machine's scale and customization requirements. Vimfun's installation team handles on-site assembly, electrical connection, commissioning, and operator training. A dedicated project manager is assigned for all SOM4-1000D orders to coordinate the delivery and installation timeline with your facility schedule.
The SOM4-1000D can replace ID saw operations when the workpiece length exceeds what the SOM4-750D handles, or when throughput requirements demand the maximum capacity tier. However, for most ID saw replacement scenarios, the SOM4-750D is the more common choice. We recommend discussing your specific workpiece dimensions and volume with our engineers to confirm which model is the right fit.
