Overview
The DN Solutions DNC 8050 is a hybrid turning/grinding machine from DN Solutions' Quartz Grinding lineup, combining CNC lathe functionality with an integrated grinding spindle on a single platform. It's designed for parts that need both turned and ground surfaces without moving between machines — think bearing seats, seal journals, and precision bores on shafts and housings.
The main turning spindle runs at 2,840 RPM with 14.1 kW (19 hp) of power, paired with a chuck range of 12 to 20 inches depending on workpiece requirements. Max turning diameter hits 810 mm (31.9 in), giving the machine a generous work envelope for medium-to-large parts. The integrated grinding spindle spins at 10,000 RPM with a BT40 taper, handling both ID and OD grinding operations with the precision you'd expect from a dedicated grinder.
Axis travels are 550 mm on X and 550 mm on Z, with rapid traverse rates of 10 m/min on X and 20 m/min on Z. These aren't production-lathe speeds — the DNC 8050 prioritizes precision positioning over rapid cycle times. The compact footprint of 2,370 mm x 2,043 mm x 2,900 mm and 3,500 kg (7,716 lb) weight make it relatively easy to fit into existing shop layouts.
The real value proposition here is setup elimination. Parts that currently move from a lathe to a cylindrical grinder — accumulating handling time, requalification, and potential damage — can now be completed in one clamping. For shops grinding bearing journals on turned shafts, finish-grinding seal surfaces after turning, or producing precision bores with ground finishes, the DNC 8050 consolidates two machines into one.

Strengths & Limitations
Strengths
- Integrated 10,000 RPM grinding spindle with BT40 taper eliminates the need for a separate cylindrical grinder for many finish-grinding operations
- Flexible 12-20 inch chuck range accommodates a wide variety of part sizes on a single machine
- 810 mm max turning diameter handles medium-to-large parts including pump housings, valve bodies, and bearing housings
- Compact 2,370 mm x 2,043 mm footprint fits into most shop layouts without major rearrangement
- Single-setup turning and grinding eliminates rechucking errors and reduces part handling on precision components
- 3,500 kg weight keeps foundation requirements modest compared to dedicated production grinding machines
Limitations
- 2,840 RPM main spindle speed is relatively low for high-speed turning operations on smaller diameters
- 550 mm Z-axis travel limits turning length for longer shaft work — the DNC 8060 extends this to 650 mm
- 10 m/min X-axis rapid traverse is slow compared to production lathes, adding cycle time on parts with extensive X-axis movements
- Grinding capability is complementary, not a replacement for dedicated high-precision cylindrical grinders on critical tolerance work

Frequently Asked Questions
01
The DNC 8060 extends the Z-axis travel to 650 mm vs 550 mm on the 8050, providing more turning length for longer parts. The 8060 also has slightly different overall dimensions. Both share the same grinding spindle, turning spindle, and core capabilities. Choose the 8060 when your parts regularly exceed 550 mm in length.
02
For many applications, yes — particularly bearing seats, seal journals, and precision bores where grinding follows turning. However, for high-volume dedicated grinding operations or ultra-tight tolerances below 1-2 microns, a purpose-built cylindrical grinder will still outperform this hybrid platform. The DNC 8050 is about consolidating operations, not replacing dedicated grinding lines.
03
The BT40 grinding spindle taper supports standard BT40-mounted grinding wheels for both ID and OD grinding. Wheel selection depends on the material and finish requirements. DN Solutions provides application engineering support for optimal wheel specification based on your specific parts.
04
New DNC 8050 machines typically price between $200,000 and $320,000 depending on configuration, chuck size selection, and grinding options. The integrated grinding capability adds a premium over a standard turning center, but the cost is well below purchasing separate turning and grinding machines.
