How much does the Grob G150 cost?
Estimated price range
Our best estimate for a 5-axis machining center in this class — not a quote from Grob-Werke. Configuration moves it a long way.
Overview
The GROB G150 is a small 5-axis universal machining center with 450/670/665 mm of X/Y/Z travel, a 380 mm table and a 580 mm interference diameter. GROB's technical data for it is brief, and some rows give paired figures without saying which case each covers, so a few points below need confirming with GROB before an order.
The travels are unusual in proportion. Y and Z, at 670 mm and 665 mm, are each about half as long again as the 450 mm of X, which gives the spindle a long reach along and into a part held on a small table. The table is 380 mm in diameter and the pallet 320 x 320 mm, while the interference diameter is 580 mm, so fixture and part can swing wider than the table they sit on. The A axis is listed at 230 degrees. Table load is given as 220/250 kg, and the row does not label the two figures.
Axis speed is listed as 50,40,60 m/min, and the rapid traverse row gives 60 m/min (2,362 ipm). The tool interface is HSK-E40/HSK-A63, with one row marking HSK-E40 as the option. The spindle data sits beside an industry row (medical technology) and a material row (stainless steel), so it reads as one configuration for that kind of work and not as the full spindle range: a 21,000 rpm motorized spindle with 29 kW/39 Nm.
When the part outgrows this envelope, the G350 has 600 mm of X travel and a 12,000 rpm standard spindle with 83 Nm.

Strengths & Limitations
Strengths
- Y and Z travels of 670 mm and 665 mm on a machine with 450 mm of X, so tall and deep features are reachable on small parts
- 580 mm interference diameter around a 380 mm table leaves room for fixtures wider than the table
- HSK-E40/HSK-A63 tool interface, so the machine can be matched to small-tool work or to an existing HSK-A63 tool stock
- A 21,000 rpm motorized spindle with 29 kW/39 Nm is listed for stainless steel work in medical technology
- Rapid traverse is listed at 60 m/min (2,362 ipm)
Limitations
- X travel is 450 mm and the pallet 320 x 320 mm; the G350 offers 600 mm of X for parts that do not fit
- 39 Nm on the listed 21,000 rpm spindle suits small cutters and finishing, not heavy roughing
- The table load row (220/250 kg) and the tool interface row give alternatives without saying which belongs to which build
- No tool magazine capacity, machine weight or control is listed in the table

Frequently Asked Questions
01
450 mm in X, 670 mm in Y and 665 mm in Z. Axis speed is listed as 50,40,60 m/min and rapid traverse as 60 m/min (2,362 ipm). The A axis is listed at 230 degrees.
02
The table is 380 mm in diameter, the pallet is 320 x 320 mm and the interference diameter is 580 mm, which is the limit for the part and fixture together as they swing. Table load is given as 220/250 kg; the row does not say which figure applies to which build, so confirm that with GROB.
03
The table shows a 21,000 rpm motorized spindle with 29 kW/39 Nm, alongside rows naming medical technology and stainless steel, so it describes one application setup. The tool interface is HSK-E40/HSK-A63. Ask GROB which other spindles are offered if the work needs more torque than 39 Nm.
04
The G350 is the larger machine: 600 mm of X travel against 450 mm, 855 mm of Y against 670 mm and 750 mm of Z against 665 mm. The G350 is listed with HSK-A63 only and a 12,000 rpm, 83 Nm standard spindle, while the G150 table also lists HSK-E40.
