Overview
The DN Solutions DNC 65 is a quartz grinding horizontal turning center purpose-built for machining non-ferrous metals — specifically semiconductor components, quartz parts, and similar materials that demand contamination-free grinding and turning in a single setup. This is not a general-purpose lathe or surface grinder; it's a specialized machine designed to prevent non-ferrous metal penetration into the machine structure while delivering the precision these components require.
The DNC series combines CNC turning capability with an integrated grinding spindle, allowing shops to rough-turn and finish-grind quartz and ceramic components without moving parts between machines. The grinding spindle runs up to 10,000 RPM with a BT40 tool shank, delivering the surface speeds needed for precision grinding of hard, brittle materials. The main turning spindle provides conventional CNC turning capability for rough shaping before the grinding operation refines the final dimensions and surface finish.
The machine runs on a Fanuc control and features an ATC (automatic tool changer) that can hold up to 40 tools, enabling complex multi-operation cycles. The compact footprint keeps floor space requirements reasonable for cleanroom-adjacent installations common in semiconductor manufacturing. DN Solutions designed the DNC series specifically for the semiconductor supply chain, where quartz components like wafer carriers, process tubes, and chamber parts require tight tolerances and pristine surface finishes.

Strengths & Limitations
Strengths
- Combined turning and grinding in a single machine eliminates part transfers and re-fixturing for semiconductor quartz components
- 10,000 RPM grinding spindle with BT40 taper delivers the surface speeds and rigidity needed for precision grinding of brittle materials
- Purpose-built design prevents non-ferrous metal contamination — critical for semiconductor component cleanliness requirements
- ATC with up to 40 tools enables complex multi-operation cycles without manual intervention
- Compact footprint suitable for cleanroom-adjacent installations common in semiconductor fabs
Limitations
- Highly specialized machine with limited general-purpose turning capability — not cost-effective for conventional metalcutting work
- Niche application limits used market availability and resale value compared to general-purpose CNC lathes
- Requires operators trained in both CNC turning and grinding processes for optimal results
- Limited dealer network expertise compared to mainstream DN Solutions turning centers

Frequently Asked Questions
01
New DNC 65 machines run approximately $200,000-$300,000 depending on configuration and tooling package. The specialized nature of these machines means pricing varies significantly by application. Contact DN Solutions or an authorized distributor for exact pricing.
02
The DNC 8060 is a larger machine with a 12-inch chuck and 810 mm max turning diameter, compared to the DNC 65's 6.5-inch chuck and 650 mm capacity. The 8060 also features a 2,840 RPM main spindle. Both share the same quartz grinding concept with integrated grinding spindles.
03
While designed for quartz and non-ferrous materials used in semiconductor components, the DNC 65 can machine other non-ferrous metals, ceramics, and glass materials. It's not intended for steel or iron machining — use a standard Puma turning center for ferrous metals.
04
The DNC series is designed from the ground up to prevent non-ferrous metal contamination. Standard lathes with grinding attachments don't have this protection. The DNC's sealed design, contamination barriers, and purpose-built structure ensure the material purity semiconductor components demand.
