How much does the Huron KX 50 M cost?
Price estimate
We do not have a price for the Huron KX 50 M 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 KX 50 M is a fixed-portal five-axis machining centre with a forked milling head and a 75 kW, 20,000 rpm spindle. Travels are 2,000 x 1,700 x 900 mm (78.7 x 66.9 x 35.4 in) over a fixed table of 2,200 x 1,250 mm. It is the shorter of the two KX 50 machines in what Huron calls the KX Large Series.
The spindle figures tell you what the machine is for. Seventy-five kilowatts with only 75 Nm of torque and a characteristic speed of 9,550 rpm describes a spindle that makes its power at high speed. That is the profile of an aluminium structural-parts machine, cutting at high feed with small to medium tools, and Huron names the aeronautical sector among the uses of the series.
B and C axes sit in the head. B swivels +/- 110° and C rotates +/- 360°, both at 100 rpm, with 4,000 Nm quoted for motor and clamping torque. Fast head axes plus 40 m/min linear rapids suit simultaneous contouring. Huron lists direct measurement on the linear and rotary axes, and states 0.007 mm positioning on X, Y and Z and 10 sec on B and C.
The table takes 4,000 kg (8,818 lb). The magazine has 30 housings for tools up to 90 mm in diameter and 8 kg. Allow 6,630 x 8,700 mm of floor and 5,140 mm of height.

Strengths & Limitations
Strengths
- 75 kW spindle at up to 20,000 rpm on an HSK 63-A taper
- Forked head with B at +/- 110° and C at +/- 360°, both at 100 rpm
- Direct measurement on linear and rotary axes, per Huron's feature list
- 40 m/min rapids on X, Y and Z
- Y travel of 1,700 mm exceeds the 1,250 mm table width
Limitations
- Spindle torque is 75 Nm, which rules out heavy cuts in steel or titanium

Frequently Asked Questions
01
An HSK 63-A spindle with 75 kW, 75 Nm and a maximum of 20,000 rpm. The characteristic speed is 9,550 rpm, so the spindle is designed to deliver its power at high speed. It suits light alloys far better than heavy steel roughing.
02
The machine has a forked head. B swivels +/- 110° and C rotates +/- 360°, each at 100 rpm. Huron lists 4,000 Nm in the row for motor and clamping torque.
03
Length. The KX 50 L has 3,000 mm of X travel, a 3,300 x 1,250 mm table and a 6,000 kg table load. The KX 50 M has 2,000 mm, 2,200 x 1,250 mm and 4,000 kg. Head, spindle, Y, Z and tool changer are the same.
04
Huron states 0.007 mm on X, Y and Z and 10 sec on B and C for positioning. Repeatability is 0.004 mm on the linear axes and 5 sec on the rotary ones.
