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 629XW is a six-axis CNC tool grinder for small tools: the listed figures cap the tool at 16 mm (0.63 in) in diameter and 200 mm (7.87 in) in length. This model does not appear in Rollomatic's current lineup, so the notes below are aimed at someone assessing a used machine.
For that small envelope the machine is heavy and strongly powered. Weight is listed at 5,200 kg (11,464 lb), and the grinding spindle delivers 13 kW (17.4 hp) at 10,000 rpm to wheels of up to 150 mm (5.9 in) in diameter. On tools no larger than 16 mm, 13 kW leaves plenty in reserve for full-depth flute grinding from solid blanks, and the mass helps keep the wheel steady while it does so.
Positioning accuracy is listed at ±0.001 mm (±0.00004 in) and repeatability at ±0.0005 mm (±0.00002 in) across the six CNC axes (X, Y, Z, A, B, C). Up to 6 grinding wheels can be carried. Software is listed as VirtualGrind Pro on a Rollomatic proprietary CNC, and oil-based coolant is the standard.
With automation, loader capacity is up to 500 tools. That figure applies only to a machine that actually has the loader, so check what is fitted. The listed figures give no axis travels, footprint or electrical supply. Before delivery, settle a floor that can carry 5,200 kg and the mist extraction and fire protection that oil coolant calls for.

Strengths & Limitations
Strengths
- 13 kW (17.4 hp) grinding spindle at 10,000 rpm on a machine limited to 16 mm (0.63 in) tools
- Positioning accuracy of ±0.001 mm (±0.00004 in) with ±0.0005 mm (±0.00002 in) repeatability in the listed figures
- Loader capacity of up to 500 tools when automation is fitted
- Six CNC axes (X, Y, Z, A, B, C) and up to 6 grinding wheels
- 5,200 kg (11,464 lb) of machine mass behind a small work envelope
Limitations
- Maximum tool diameter is 16 mm (0.63 in), so larger end mills and drills are outside its range
- Tool length stops at 200 mm (7.87 in)
- The 500-tool loader capacity is tied to automation, which a given machine may not have
- Oil-based coolant is the standard and no other coolant type is listed

Frequently Asked Questions
01
The listed figures give a maximum tool diameter of 16 mm (0.63 in) and a maximum tool length of 200 mm (7.87 in). The largest grinding wheel is 150 mm (5.9 in) in diameter.
02
Positioning accuracy is listed at ±0.001 mm (±0.00004 in) and repeatability at ±0.0005 mm (±0.00002 in). These are the listed figures for the model, not a measurement of any one machine, so ask for a recent calibration or test report.
03
Up to 500 tools, and only with automation. The listed figures tie that capacity to the automation package, so a machine without the loader is loaded by hand.
04
The machine weight is listed at 5,200 kg (11,464 lb). Oil-based coolant is standard. Plan the floor loading for that weight and provide mist extraction suited to oil; the listed figures do not include a footprint or power supply.
