How much does the Walter Helitronic Raptor 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 Raptor is a tool grinding machine that accepts workpieces of 3 - 320 mm (0.12 - 12.59 inch) in diameter and up to 50 kg (110 lbs), with an 11,5 kW (15.42 hp) spindle running at up to 10,500 rpm. Its table is short, and the picture it gives is of a general-purpose machine: a wide diameter range, a mid-size motor and a long Z axis.
Z travel is 660 mm (25.98 inch), roughly double the 320 mm (12.59 inch) of Y. X travel is 460 mm (18.11 inch). Travel alone does not tell you how long a tool the machine accepts, because the wheel pack and the clamping use part of it. No maximum tool length is listed, and it should be asked for directly.
The largest grinding wheel is 200 mm (7.87 inch). With a 320 mm (12.59 inch) cutter on the machine, the workpiece is larger than the wheel, which is normal for sharpening big disc cutters but worth a collision check on deep gashes. The C axis swivels ± 200 °.
Against the Walter Helitronic Micro, which has 385 mm (15.16 inch) of X, 320 mm (12.59 inch) of Z and 7 kW (9.39 hp), the Raptor is the larger and stronger machine at the same 10,500 rpm.

Frequently Asked Questions
01
Workpiece diameter is 3 - 320 mm (0.12 - 12.59 inch) and the maximum workpiece weight is 50 kg (110 lbs). The table does not give a maximum tool length. Z travel is 660 mm (25.98 inch), but an axis travel is not a tool length, so confirm the limit for your longest tool.
02
Spindle power is 11,5 kW (15.42 hp) and the maximum spindle speed is 10,500 rpm, with a grinding wheel of up to 200 mm (7.87 inch) in diameter. The Walter Helitronic Micro reaches the same 10,500 rpm with 7 kW (9.39 hp).
03
X travel is 460 mm (18.11 inch), Y travel is 320 mm (12.59 inch) and Z travel is 660 mm (25.98 inch). The C axis has a swiveling range of ± 200 °. Travel speeds are not listed.
