How much does the Dener TDC 3116 cost?
Price estimate
We do not have a price for the Dener TDC 3116 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
With the Dener TDC 3116, Dener's double column machining center moves into heavy-part territory. X travel is 3,100 mm (122 in), Y 1,600 mm and Z 1,020 mm, and the table carries 10,000 kg (22,046 lb).
The Z axis changes the character of the machine. At 1,020 mm it is far taller than on the TDC 2112, so boxes, gearbox housings and tall welded frames come into range, not only plates. The columns are 1,700 mm apart and the table is 3,000 x 1,500 mm.
Moving that mass takes larger drives and lower speeds. Axis motors are listed as 9/7/7 kW, and rapid traverse is 12/12/12 m/min. Cutting feed runs from 1~10 m/min.
The spindle is common to the TDC range: BBT 50, 10,000 rpm, 22/26 kW, direct drive. Positioning accuracy is ±0.008 mm per 300 mm of stroke. A 40-tool magazine is listed for this size. On long cycles with roughing, finishing and drilling tools in one setup, that capacity avoids manual tool changes mid-program.
The cabin is semi-enclosed, which is usual for machines loaded by overhead crane.

Frequently Asked Questions
01
Travels are 3,100 x 1,600 x 1,020 mm, the table is 3,000 x 1,500 mm and there are 1,700 mm between the columns. The table load limit is 10,000 kg (22,046 lb).
02
12/12/12 m/min in X, Y and Z, with a cutting feed rate of 1~10 m/min. The smaller TDC 2112 traverses at 24 m/min in X and Y.
03
The specification table lists a tool capacity of 40. Dener describes the changer as a BBT 50 arm-type ATC with a capacity of 24 or 40 tools.
04
A Mitsubishi M80A-8A with conversational programming (Navi-Mill) is standard. A FANUC control unit is on the options list, as are tool and workpiece measuring probes.
