How much does the Walter Helitronic Power cost?
Estimated price range
Our best estimate for a cnc grinding machine in this class — not a quote from United Grinding (Walter). Configuration moves it a long way.
Overview
The Walter Helitronic Power is a 5-axis tool grinder (X, Y, Z, A, C) with long linear travels for its class: 650 mm (25.6 in.) in X, 350 mm (13.8 in.) in Y and 720 mm (28.3 in.) in Z. It grinds tools from 3 mm (0.12 in) to 315 mm (12.4 in) in diameter and carries workpieces up to 50 kg (110.3 lbs.).
Those travels are what separate it from the smaller Helitronic machines. The Walter Helitronic Raptor has 460 mm (18.11 inch) of X, 320 mm (12.59 inch) of Y and 660 mm (25.98 inch) of Z. The Power is longer on all three, and the gain is largest in X. Extra travel is what lets a large-diameter cutter and a full-size wheel pass clear of each other between operations.
The drive rows give 26 kW (35.3 hp) of power at a speed of 10500 rpm. The Walter Helitronic Raptor is listed at 11,5 kW (15.42 hp) with the same 10,500 rpm, so the Power has more than twice the power at an unchanged top speed. That reserve is useful for deep flutes ground from solid, where the wheel is buried in the blank and the load is high for the whole pass. The maximum grinding wheel is ⌀254 mm (10 in.).
On tool length the table is not uniform, and a buyer should settle it before ordering. One row gives a maximum tool length of 350 mm (13.8 in), another a maximum workpiece length of 520 mm (20.5 in.). The table does not say which operation or clamping each belongs to, so send a drawing of the longest tool and ask which limit applies.
For installation, the machine measures 2753 mm (108.4 in.) long, 2278 mm (89.7 in.) wide and 2328 mm (91.6 in.) high and weighs 5300 kg (11684.5 lbs.).

Strengths & Limitations
Strengths
- Linear travels of 650 mm (25.6 in.) in X, 350 mm (13.8 in.) in Y and 720 mm (28.3 in.) in Z
- 26 kW (35.3 hp) of power at 10500 rpm, more than twice the 11,5 kW (15.42 hp) of the Walter Helitronic Raptor
- Tool diameters from 3 mm (0.12 in) up to 315 mm (12.4 in)
- Grinding wheels up to ⌀254 mm (10 in.)
- Workpieces up to 50 kg (110.3 lbs.)
Limitations
- The table gives two length limits, 350 mm (13.8 in) as maximum tool length and 520 mm (20.5 in.) as maximum workpiece length, without saying when each applies
- At 5300 kg (11684.5 lbs.) and 2753 mm (108.4 in.) by 2278 mm (89.7 in.), it needs a planned floor position and rigging
- Tools under 3 mm (0.12 in) in diameter are outside the listed range
- No axis speeds, accuracy figures or loader details appear in the table

Frequently Asked Questions
01
Tool diameter runs from 3 mm (0.12 in) to 315 mm (12.4 in), and workpiece weight goes up to 50 kg (110.3 lbs.). For length the table gives a maximum tool length of 350 mm (13.8 in) and a maximum workpiece length of 520 mm (20.5 in.) without explaining the difference, so confirm the limit for your longest tool.
02
The table lists 26 kW (35.3 hp) of power and a speed of 10500 rpm, with a maximum grinding wheel diameter of ⌀254 mm (10 in.). The Walter Helitronic Raptor is listed at 11,5 kW (15.42 hp) and 10,500 rpm, and the Walter Helitronic Micro at 7 kW (9.39 hp) and 10,500 rpm.
03
The Power has longer travels and more power. It moves 650 mm (25.6 in.) in X, 350 mm (13.8 in.) in Y and 720 mm (28.3 in.) in Z, where the Walter Helitronic Raptor has 460 mm (18.11 inch), 320 mm (12.59 inch) and 660 mm (25.98 inch). Power is 26 kW (35.3 hp) against the 11,5 kW (15.42 hp) of the Walter Helitronic Raptor. Top speed is the same.
04
The machine is 2753 mm (108.4 in.) long, 2278 mm (89.7 in.) wide and 2328 mm (91.6 in.) high, and it weighs 5300 kg (11684.5 lbs.). Those are the machine figures only. Allow extra room for door opening, service access and any coolant or filtration unit, none of which the table sizes.
