How much does the Dener TTH-8(C) cost?
Price estimate
We do not have a price for the Dener TTH-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
The Dener TTH-8(C) turns up to 438 mm (17.2 in) in diameter over a machining length of 627 mm (24.7 in). It is printed as a second column next to the TTH-8 in Dener's table.
Against the TTH-8 the diameter falls by a good deal and the length by rather less: the base column shows 528 mm (20.8 in) and 680 mm (26.8 in). Dener offers no explanation of the (C) on its page, so this text does not supply one. The practical reading is simple. Large flanges that the TTH-8 could swing may not fit here, while most shaft work still does.
In fact 627 mm remains a long machining length. It is greater than any TTC model offers and more than the TTH-12 lists.
The spindle is the TTH-8's: 4,500 rpm, an 8 inch (203 mm) chuck, a 66 mm (2.6 in) bore and 52 mm (2 in) of bar capacity, with motor power printed as 15/24.2 kW. Swing diameter is 650 mm (25.6 in). Cutting feed rate is 1~10 m/min and rapid traverse 30/30 m/min.
Standard and optional equipment are listed once for the whole series. Among the options are tool and workpiece measuring systems, a mist extraction unit, an automatic door and an air conditioner for the electrical cabinet.

Frequently Asked Questions
01
The maximum turning diameter is 438 mm (17.2 in) and the machining length 627 mm (24.7 in). The TTH-8 lists 528 mm (20.8 in) and 680 mm (26.8 in). The other eight rows of the table are the same.
02
By its figures, yes. A machining length of 627 mm (24.7 in) exceeds every TTC model in the range, and the spindle motor power is printed as 15/24.2 kW with a speed of 4,500 rpm.
03
Nothing on the product page. The TTH-8(C) appears only as a column heading, so the configuration it stands for has to be confirmed with the manufacturer or dealer.
04
The option list is common to the series: Mitsubishi M80A-8A control, C axis, tool and workpiece measuring systems, automatic bar feeder unit, programmable tailstock, part catcher, linear encoder and others.
