How much does the Dener TTC-6 cost?
Price estimate
We do not have a price for the Dener TTC-6 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 is the smallest lathe in Dener's TTC and TTH range: a slant-bed CNC turning machine with a 6 inch (152 mm) chuck and a spindle that reaches 6,000 rpm. No other model in the range turns as fast.
Maximum turning diameter is 305 mm (12 in) under a swing of 560 mm (22 in), and the machining length is 433 mm (17 in). Those are chucker proportions. The machine suits short parts such as bushes, flanges, fittings and small shafts, where spindle speed does more for cycle time than motor power.
Bar work is the other natural use. The spindle bore is 56 mm (2.2 in) and the bar capacity 45 mm (1.8 in), and an automatic bar feeder unit and a part catcher are both on the option list. With the two fitted the lathe can run small turned parts from bar with little attention.
Dener prints the spindle motor power as 11/20.4 kW. Rapid traverse is 30/30 m/min in X/Z, and the cutting feed rate is given as 1~5 m/min.
The frame is a one-piece casting with a 45° slant, carried on roller linear guideways with C1–C3 class ball screws. FANUC 0İ TFP is the standard control, with Mitsubishi M80A-8A as an option. A fully enclosed cabin, a chip conveyor and automatic lubrication and coolant systems are standard equipment.

Frequently Asked Questions
01
The maximum turning diameter is 305 mm (12 in) and the machining length 433 mm (17 in), under a swing diameter of 560 mm (22 in). The chuck is 6 inch (152 mm) and bar up to 45 mm (1.8 in) passes through the spindle.
02
The TTC-8 carries an 8 inch (203 mm) chuck, a 66 mm (2.6 in) spindle bore and 52 mm (2 in) of bar capacity, and its spindle speed is 4,500 rpm. The TTC-6 has the smaller chuck and bore but runs to 6,000 rpm and has a slightly longer machining length.
03
FANUC 0İ TFP is listed under standard equipment. Mitsubishi M80A-8A appears in the optional equipment list, so the control is a choice to make when ordering.
04
Dener prints a second column headed TTC-6(C) beside this model. It differs in two rows only: 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 page does not explain the designation.
