How much does the Dener TMU 500 cost?
Price estimate
We do not have a price for the Dener TMU 500 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 TMU 500 is a 5-axis machining center with a tilting rotary table: travels of 620 mm (24.4 in) in X, 520 mm in Y and 460 mm in Z, a B axis that tilts from -110° to +110° and a C axis with 360° of rotation. Dener states that it mills in five axes simultaneously.
The table is 650 mm across and carries 300 kg (661 lb). It turns quickly, at 120/210 rpm for B/C, and the linear axes traverse at 40 m/min, so the machine is built for dynamic contouring more than for heavy parts.
The spindle runs to 14,000 rpm. Its power is listed as 21/15 kW and its torque as 112/80 Nm at 40% and 100% duty. Tools are HSK-A63, held in a 30-tool magazine.
Accuracy is specified in detail, which is unusual on Dener's pages. Linear positioning is ±0.004 mm with ±0.002 mm repeatability. The rotary axes are given in arc seconds: 7 sec positioning and 4 sec repeatability on C, 12 sec and 8 sec on B. Linear encoders on X, Y and Z and angle encoders on B and C are standard.
The standard control is a Siemens Sinumerik One; a Heidenhain TNC 640 is optional. Through-tool coolant, spindle cooling and a belt-type chip conveyor are included.
