How much does the Huron U Mill 5 cost?
Price estimate
We do not have a price for the Huron U Mill 5 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 Huron U Mill 5 is a compact five-axis machining centre with a fixed portal and a swivelling rotary table on a cradle. Travels are 500 x 560 x 450 mm (19.7 x 22.0 x 17.7 in), the table is 500 mm in diameter, and the ISO 40 spindle produces 173 Nm at up to 10,000 rpm.
That torque figure sets the U Mill apart from Huron's high-speed five-axis machines. The spindle is rated 18 kW with a characteristic speed of 1,000 rpm, so full torque is on hand at low speed for steel, cast iron and tougher alloys. Huron describes the range as covering work from roughing to finishing in 3 or 5 axes.
The cradle tilts the A axis from +20° to -110° at 25 rpm, and C rotates 360° at 45 rpm. Those speeds suit positioning and steady simultaneous cuts more than fast contouring of small features. Table load is 450 kg (992 lb).
Huron stresses stiffness: a fixed portal in ribbed cast iron with stiffening walls to resist torsion, and a modular design. The machine weighs 11,000 kg (24,250 lb) and stands on 4,200 x 4,110 mm. Positioning is 0.015 mm and repeatability 0.005 mm on the linear axes. The 30-tool changer takes tools up to 80 mm in diameter and 300 mm long.

Frequently Asked Questions
01
500 mm in X, 560 mm in Y and 450 mm in Z, with a rapid feedrate of 40 m/min. The table is 500 mm in diameter with an admissible load of 450 kg (992 lb).
02
The A axis swivels from +20° to -110° at 25 rpm. The C axis rotates 360° at 45 rpm. The table is fixed on a cradle, which gives access to five faces of the workpiece.
03
The U Mill 6 has 700 x 740 x 550 mm travels, a 630 mm table and a 600 kg load, and weighs 13,000 kg. The rotary axes of the U Mill 6 are slower, 20 rpm on A and 35 rpm on C. Spindle, tool changer and accuracy figures are the same on both.
04
An ISO 40 spindle with a maximum speed of 10,000 rpm, 18 kW and 173 Nm. The characteristic speed is 1,000 rpm. Huron describes it as a powerful spindle with high torque for high metal removal rates.
