How much does the Dener TDC 4120 cost?
Price estimate
We do not have a price for the Dener TDC 4120 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Dener TDC 4120 is the largest double column machining center Dener lists: 4,100 mm (161.4 in) of X travel, 2,020 mm of Y and 1,020 mm of Z, with a table rated for 12,000 kg (26,455 lb).
Width is its distinguishing dimension. The columns stand 2,100 mm apart, and the Y axis covers 2,020 mm of that, so a part two metres wide can be machined across its full face. The table itself is 4,000 x 1,800 mm.
In drives and spindle the machine repeats the TDC 3116. Axis motors are 9/7/7 kW. Rapid traverse is 12 m/min per axis. The BBT 50 spindle runs at 10,000 rpm on a 22/26 kW motor, and the magazine holds 40 tools.
So the question for a buyer is purely one of part size. Are the workpieces longer than three metres, or wider than one and a half? If not, the smaller model does the same work on less floor.
At this scale, thermal growth and geometry matter more than on a small machine. Dener states ±0.008 mm positioning and ±0.004 mm repeatability per 300 mm of stroke and offers a linear encoder system as an option; over a four-metre axis that option is worth serious consideration.

Frequently Asked Questions
01
Axis travels of 4,100 mm, 2,020 mm and 1,020 mm in X, Y and Z, a 4,000 x 1,800 mm table and 2,100 mm between the columns.
02
12,000 kg (26,455 lb), on a table of 4,000 x 1,800 mm. The TDC 3116 is rated for 10,000 kg on a 3,000 x 1,500 mm table.
03
No. All three list a BBT 50 spindle at 10,000 rpm with a 22/26 kW motor. The axis motors here are 9/7/7 kW, as on the TDC 3116.
04
Positioning accuracy of ±0.008 mm and repeatability of ±0.004 mm, both per 300 mm stroke. A linear encoder system is optional equipment.
