TCK6050D CNC Slant Bed Lathe – 11/15 kW Spindle, 560 mm Swing, Two Turning Lengths

Machine shops that turn shafts, flanges, gear blanks and hydraulic parts usually end up chasing the same trade-off. A lathe rigid enough to take a decent roughing cut, yet precise enough to hold a finish tolerance without a second setup. The TCK6050D CNC slant bed lathe from BONANZA is built to sit in that middle ground. It is the higher-spec version of the TCK6050 platform, with a stiffer spindle drive, a 65 mm bore, and two bed length choices so a shop can match the machine to the parts it actually runs.

What the TCK6050D offers

The TCK6050D uses a slant bed layout, which does two things at once: it keeps the cutting zone open so chips fall away instead of sitting under the tool, and it lowers the effective height of the turret and carriage relative to the guideways, which helps with rigidity during heavier cuts. The bed gives 560 mm of swing, so a 410 mm diameter workpiece turns comfortably, and the cross slide still clears 320 mm.

BONANZA sells the TCK6050D in two configurations. The TCK6050D-500 turns work up to 500 mm long, while the TCK6050D-1000 stretches that to 980 mm. Everything else on the machine, from the spindle nose to the X-axis travel, stays the same across both versions. That makes the choice simple: match the bed length to the longest part you expect to see on a regular basis, and you are not paying for travel you will never use.

Specifications at a glance

Spindle and drive: where the D model differs

Both TCK6050 variants share the A2-6 spindle nose and the 65 mm bore. What sets the D model apart is the drive motor, rated at 11 kW continuous and 15 kW at higher duty, which gives the machine noticeably more headroom when the cut gets heavy. In practice that means a shop can rough a forged flange or a heat-treated shaft blank with a bigger depth of cut, then finish on the same setup without babying the feed rate.

The 65 mm spindle bore and 50 mm bar capacity also matter for shops running bar work. If you add a bar feeder, the TCK6050D handles stock up to 50 mm through the spindle, which covers a large share of common shaft and pin diameters. For shops that mostly chuck individual blanks, the through-bore simply means you never have to think about it.

Axis layout and tailstock

The X-axis travels 280 mm and the Z-axis covers 630 mm or 1120 mm depending on the bed length. Rapid traverse sits at 15 m/min on both axes, which is not about chasing the fastest cycle time on paper. It matters more in real production, where a machine that moves between positions quickly shortens every non-cutting part of the cycle on short parts.

Both versions come with a tailstock, with 450 mm of travel on the -500 and 900 mm on the -1000, and a 100 mm quill stroke. Center-supported turning of long, slender shafts is where a slant bed lathe earns its keep, and the tailstock travel is sized to match each bed length rather than being a token add-on.

Where it fits in the BONANZA line

The TCK6050D sits above the standard TCK6050 CNC slant bed lathe for shops that want the extra spindle power, and below the TCK6350D and TCK70D heavy-duty models, which step up to A2-8 and A2-11 spindles with 85 mm and larger through-bores for big bar and heavy roughing work. If your parts are mostly in the 50 mm bar or 410 mm chucked-diameter range, the TCK6050D is likely the sweet spot. If you need two spindles or live tools, BONANZA also builds the TCK6050SY mill-turn machine on a similar envelope.

More options are listed on the CNC slant bed lathe series page, where you can compare the TCK50 compact model through the long-bed TCK70D side by side.

Workpieces that suit the TCK6050D

Typical parts for this machine class include:

• Flanges and bearing housings up to 410 mm diameter, where the 11/15 kW motor handles interrupted cuts on castings without stalling
• Shafts and spindles up to 980 mm long between centers, held by the tailstock with its 100 mm quill
• Gear blanks, pulleys and sleeves that need a clean bore and face in one clamping
• Bar-fed pins, rollers and bushings up to 50 mm stock diameter

Shops producing hydraulic components and valve parts tend to like this platform because the slant bed keeps swarf clear of the chuck and tooling across long unmanned runs. Job shops value the two-bed-length choice, since it stops them from buying a 1 m machine to make 300 mm parts.

Buying considerations

Before you request a quote, decide which bed length matches your longest recurring part, and whether you will feed bar through the spindle or only work with chucked blanks. Both answers affect the configuration but not the core machine. The BONANZA sales team can also confirm lead times and shipping for your region, and they will normally quote the machine with the control system option that suits your existing tooling and programming habits.

Frequently asked questions

What is the difference between the TCK6050 and the TCK6050D?

The TCK6050D is the higher-power version of the TCK6050 slant bed lathe. It keeps the same A2-6 spindle nose and 65 mm bore, but the spindle motor is rated at 11/15 kW instead of the standard model’s output, giving it more margin for heavier roughing cuts. It is offered in two bed lengths, 500 mm and 1000 mm.

Can the TCK6050D run bar-fed work?

Yes. The spindle bore is 65 mm and maximum bar capacity is 50 mm, so the machine works with a bar feeder for stock up to that diameter.

What is the largest workpiece the TCK6050D-1000 can turn?

With the 1000 mm bed, maximum turning length is 980 mm and maximum turning diameter is 410 mm (320 mm over the cross slide), with 560 mm swing over the bed. The TCK6050D-500 version turns up to 500 mm long.

If you are weighing the TCK6050D against the standard TCK6050 or a mill-turn alternative, send your part drawings and target cycle times to BONANZA for a recommendation based on the actual work envelope, not a brochure.
