How much does the Rollomatic GrindSmart 830XW cost?
Estimated price range
Our best estimate for a cnc grinding machine in this class — not a quote from Rollomatic. Configuration moves it a long way.
Overview
The Rollomatic GrindSmart 830XW is a CNC tool grinder for tools from Ø 1.0 to 32.0 mm (0.04 to 1.25 in), built on 320 mm (12.6 in) of X, 200 mm (7.87 in) of Y and 400 mm (15.7 in) of Z travel. Rollomatic pairs those linear axes with three direct-drive rotary axes, an 11 kW (15 HP) direct-drive grinding spindle and a wheel pack capacity of 15.
The A and B axes each swing from -30° to 210°, a 240° stroke, at up to 10800°/min, and the C axis rotates the tool at up to 1000 rpm. Position feedback is absolute throughout: linear scales resolving 0.00001 mm on X, Y and Z, and optical encoders resolving 0.00001° on the rotary axes. Absolute feedback means the axes know where they are at power-up, with no reference run. Linear rapid traverse is 12 m/min (473 in/min).
The grinding spindle is rated 11 kW (15 HP) with a 14 kW (19 HP) peak and runs from 500 to 8000 rpm. Wheels up to Ø 175 mm (7 in) mount on an HSK50E attachment, 4 to a pack, and the machine stores 15 packs. That is a large wheel library for one grinder. A family of tools needing different flute, gash and relief wheels can stay set up, without an operator swapping packs between batches.
Automation is on the same scale. The robot handles up to 4500 tools in 10 cassettes, with an overall tool length of up to 450 mm (18 in). That is longer than the 400 mm of Z travel, so ask Rollomatic how much of a long tool can be ground in one clamping. Clamping is pneumatic, through Schaublin and Nann adapters.
The machine weighs 6200 kg and has a listed footprint of 2200 x 2500 x 2200 mm (86.6 x 98.4 x 86.6 in). It needs a 3 x 400 V / 45 A supply, and total power is a maximum of 27 kW.

Strengths & Limitations
Strengths
- Grinding range of Ø 1.0 to 32.0 mm (0.04 to 1.25 in) on one machine
- Wheel pack capacity of 15 with 4 wheels per pack, on an HSK50E wheel attachment
- Robot capacity of up to 4500 tools in 10 cassettes, with overall tool length up to 450 mm (18 in)
- Direct-drive A, B and C axes; A and B each cover a 240° stroke at 10800°/min
- Absolute linear scales with 0.00001 mm resolution and absolute optical rotary encoders at 0.00001°
- 11 kW (15 HP) direct-drive spindle with a 14 kW (19 HP) peak
Limitations
- Spindle speed tops out at 8000 rpm, which sets the ceiling on wheel peripheral speed with wheels of Ø 175 mm (7 in) or less
- The grinding range starts at Ø 1.0 mm, so micro tools below that diameter are outside the table
- Rollomatic's table gives encoder resolution but no positioning accuracy or repeatability figure
- At 6200 kg, with a 3 x 400 V / 45 A supply and up to 27 kW of total power, it needs a properly rated floor and feed
