How much does the Dener TTC-6(C) cost?
Price estimate
We do not have a price for the Dener TTC-6(C) 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 TTC-6(C) is listed next to the TTC-6 in Dener's lathe table and shares most of that machine's figures. Two rows are different: the maximum turning diameter is 275 mm (10.8 in) and the machining length is 362 mm (14.3 in).
The TTC-6 itself prints 305 mm (12 in) and 433 mm (17 in) in those rows. Dener's page gives no account of what the (C) in the name refers to, and none is offered here. What the table establishes is that this column has the smaller working envelope of the pair, so a part near the limits of the base model has to be checked against these lower figures.
Everything about the spindle carries over. It is a 6,000 rpm spindle with a 6 inch (152 mm) chuck, a 56 mm (2.2 in) bore and a bar capacity of 45 mm (1.8 in). Motor power is printed as 11/20.4 kW. The swing diameter remains 560 mm (22 in).
Axis figures are unchanged too, at 30/30 m/min rapid traverse and a 1~5 m/min cutting feed rate.
The equipment lists on the page are written for the series as a whole. Standard items include the FANUC 0İ TFP control, a BMT / slot-type turret, roller linear guideways and a chip conveyor. A buyer should ask the supplier to state in the quotation exactly which configuration the (C) column describes.

Strengths & Limitations
Strengths
- Same 6,000 rpm spindle as the TTC-6
- 56 mm (2.2 in) spindle bore and 45 mm (1.8 in) bar capacity are unchanged
- BMT / slot-type turret and roller linear guideways listed as standard
- 30/30 m/min rapid traverse in both axes
Limitations
- Turning diameter drops to 275 mm (10.8 in) from the 305 mm (12 in) of the TTC-6
- Machining length of 362 mm (14.3 in) is shorter than on the base model
- The page does not explain what the (C) designation covers
- Smallest chuck of the range at 6 inch (152 mm)

Frequently Asked Questions
01
Two rows of the table. The TTC-6(C) lists a maximum turning diameter of 275 mm (10.8 in) and a machining length of 362 mm (14.3 in); the TTC-6 lists 305 mm (12 in) and 433 mm (17 in). All other rows are identical.
02
Dener's product page does not say. It prints the TTC-6(C) as a second column next to the TTC-6 without a note, so the meaning of the suffix should be confirmed with Dener or its dealer before ordering.
03
A 6,000 rpm spindle with a 6 inch (152 mm) chuck and a 56 mm (2.2 in) bore. The spindle motor power is printed as 11/20.4 kW, and bar capacity is 45 mm (1.8 in).
04
The swing diameter is 560 mm (22 in), the same as the base model. The maximum turning diameter, the figure that limits the actual cut, is 275 mm (10.8 in).
