How much does the Blohm Profimat 408 cost?
Estimated price range
Our best estimate for a cnc grinding machine in this class — not a quote from Blohm. Configuration moves it a long way.
Overview
The Blohm Profimat 408 is a grinder whose table drive covers both creep-feed and pendulum grinding, with a 400 x 800 mm (15.7 x 31.5 in) table and a 22 kW (29.5 HP) grinding spindle. Blohm's current lineup does not list it, and the listed figures are unverified.
The table speed rows explain the machine. In creep feed the table moves at 0.01 – 6,000 mm/min, slow enough at the bottom of the range for a full-depth pass in one stroke. In pendulum mode it reciprocates at up to 40,000 mm/min for conventional light-cut surface grinding. One machine can rough a deep form and finish a flat face, provided the wheel and dressing equipment on the particular machine suit both.
X and Z run on hydrostatic guideways. An oil film carries the load, so there is no stick-slip at the very low feed rates creep-feed grinding uses and no metal-to-metal wear in the ways. It also means a hydraulic supply to maintain, which is worth inspecting on a used machine. The base is polymer concrete of the Granitan type.
Capacity is modest. Longitudinal travel and grinding length are both 900 mm (35.4 in), cross travel is 450 mm (17.7 in) and vertical travel 500 mm (19.7 in), with workpieces up to 300 mm (11.8 in) high and 300 kg (660 lb). The wheel can be up to 400 mm (15.7 in) in diameter and 100 mm (3.9 in) wide at 80 m/s. The Profimat 412 keeps these figures and lengthens the table to 400 x 1,200 mm (15.7 x 47.2 in). Control is a Siemens 840D sl with the Blohm OP 15 interface.

Strengths & Limitations
Strengths
- Table speed range covers creep feed at 0.01 – 6,000 mm/min and pendulum grinding at up to 40,000 mm/min
- Hydrostatic guideways on the X and Z axes
- 22 kW (29.5 HP) grinding spindle with a wheel peripheral speed of up to 80 m/s
- Wheel up to 100 mm (3.9 in) wide for broad profiles
- Polymer concrete (Granitan-type) machine base
Limitations
- Grinding length is 900 mm on a 400 x 800 mm (15.7 x 31.5 in) table, so long parts need the Profimat 412
- Workpiece weight is limited to 300 kg (660 lb) and height to 300 mm (11.8 in)
- Maximum wheel diameter is 400 mm (15.7 in)
- Not in Blohm's current lineup; the listed figures are unverified

Frequently Asked Questions
01
The listed table speeds cover both: 0.01 – 6,000 mm/min in creep feed and up to 40,000 mm/min in pendulum mode. Whether a given machine is equipped for both depends on its dressing and coolant equipment, which the table does not describe.
02
The table is 400 x 800 mm (15.7 x 31.5 in). Longitudinal travel is 900 mm (35.4 in), cross travel 450 mm (17.7 in) and vertical travel 500 mm (19.7 in). Maximum workpiece height is 300 mm (11.8 in) and maximum weight 300 kg (660 lb).
03
The listed guideway system is hydrostatic on the X and Z axes. That supports smooth motion at the low feed rates of creep-feed grinding, and on a used machine the hydrostatic supply is one of the first things to have checked.
04
Table length and load. The Profimat 412 has a 400 x 1,200 mm (15.7 x 47.2 in) table, 1,300 mm (51.2 in) of longitudinal travel and a 500 kg (1,100 lb) workpiece limit, against 400 x 800 mm (15.7 x 31.5 in), 900 mm (35.4 in) and 300 kg (660 lb) on the Profimat 408. Spindle power and wheel size are listed the same.
