How much does the Dener TTC-8(C) cost?
Price estimate
We do not have a price for the Dener TTC-8(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
With a machining length of 335 mm (13.2 in), the Dener TTC-8(C) has the shortest Z capacity printed anywhere in Dener's TTC and TTH lathe tables. Its maximum turning diameter is 275 mm (10.8 in).
The column stands beside the TTC-8, which lists 305 mm (12 in) and 406 mm (16 in) for the same two rows. Nothing else differs between them, and Dener does not say on the page what the (C) suffix denotes.
The result on paper is a large spindle in a small envelope. An 8 inch (203 mm) chuck, a 66 mm (2.6 in) bore and 52 mm (2 in) of bar capacity sit in front of barely a third of a metre of machining length. That fits disc-shaped and short work well: rings, flanges, pulleys, short bar parts. It does not fit shafts.
Spindle speed is 4,500 rpm and the motor power row reads 11/20.4 kW. Swing diameter is 560 mm (22 in). Rapid traverse and cutting feed are printed as 30/30 m/min and 1~5 m/min.
Since the equipment lists are shared by all models on the page, they say nothing particular about this column. The frame is described as a one-piece rigid casting with a 45° slant, and the standard list includes an oil and water separator unit and an external transformer for 3-phase 380/200 V supplies.

Strengths & Limitations
Strengths
- 8 inch (203 mm) chuck with a 66 mm (2.6 in) spindle bore
- Bar capacity of 52 mm (2 in)
- Spindle motor power printed as 11/20.4 kW, as on the TTC-8
- Oil and water separator unit and external transformer are standard equipment
Limitations
- Machining length of 335 mm (13.2 in), the shortest in the range
- Turning diameter of 275 mm (10.8 in), less than the 305 mm (12 in) of the TTC-8
- Meaning of the (C) designation is not given on the page
- Not suited to shaft work between centres at this length

Frequently Asked Questions
01
Only in working envelope. The TTC-8(C) lists a 275 mm (10.8 in) maximum turning diameter and a 335 mm (13.2 in) machining length, where the TTC-8 lists 305 mm (12 in) and 406 mm (16 in). Chuck, spindle, motor and feeds are the same.
02
The machining length is 335 mm (13.2 in). That is the smallest figure in Dener's lathe tables, so the model is best matched to short chucked parts and bar work.
03
No. The product page prints the TTC-8(C) column without a description. The supplier should confirm what equipment the column represents and why its travel figures are lower.
04
The chuck diameter is 8 inch (203 mm). The spindle bore is 66 mm (2.6 in) and the bar capacity 52 mm (2 in), with an automatic bar feeder unit available as optional equipment.
