How much does the Blohm PROFIMAT MT 612 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 MT 612 is listed with two grinding modes on one machine, pendulum surface grinding and creep-feed profile grinding, on a 600 × 1,200 mm (23.6 × 47.2 in) table that carries up to 1,200 kg (2,646 lb). It does not appear in Blohm's current lineup, and the listed figures are unconfirmed.
The two modes ask different things of a grinder. Pendulum grinding takes light cuts with the table reciprocating quickly; creep-feed grinding takes the full profile depth in one slow pass and needs power and a wheel that holds its form. The listed 37 kW (49.6 HP) spindle and the diamond form roll CNC dressing, which runs automatically in-cycle, serve the second case: the roll restores the wheel profile during the cycle, so a deep form can be ground without stopping to dress.
Wheels are up to 500 mm (19.7 in) in diameter and 100 mm (3.9 in) wide, at a peripheral speed of up to 80 m/s, so a single profile can be as wide as the wheel. Longitudinal travel is 1,400 mm (55.1 in), longer than the 1,200 mm table, with 700 mm (27.6 in) of cross travel and 600 mm (23.6 in) of vertical travel.
Longitudinal rapid traverse is 30,000 mm/min (1,181 ipm). The base is polymer concrete of the Granitan type and the control is a Siemens 840D sl with the Blohm OP 15 interface. Compared with the Profimat 412, which is listed at 22 kW (29.5 HP) on a 400 x 1,200 mm (15.7 x 47.2 in) table with a 500 kg (1,100 lb) limit, this is the wider, heavier and more powerful machine.

Strengths & Limitations
Strengths
- Pendulum surface grinding and creep-feed profile grinding listed on the same machine
- 37 kW (49.6 HP) grinding spindle with a wheel peripheral speed of up to 80 m/s
- Diamond form roll CNC dressing, automatic and in-cycle
- 600 × 1,200 mm (23.6 × 47.2 in) table working area rated for 1,200 kg (2,646 lb)
- Wheels up to 500 mm (19.7 in) in diameter and 100 mm (3.9 in) wide
Limitations
- Profile width in one pass is bounded by the 100 mm (3.9 in) maximum wheel width
- No coolant, table speed or guideway rows are listed, all of which matter for creep-feed work
- Longitudinal travel of 1,400 mm (55.1 in) leaves limited overrun beyond the 1,200 mm table length
- Not in Blohm's current lineup, and the listed figures are unconfirmed

Frequently Asked Questions
01
The table lists pendulum surface grinding plus creep-feed profile grinding. For the profile work it lists diamond form roll CNC dressing that runs automatically in-cycle, and a 37 kW (49.6 HP) grinding spindle.
02
The table working area is 600 × 1,200 mm (23.6 × 47.2 in). Travels are 1,400 mm (55.1 in) longitudinal, 700 mm (27.6 in) cross and 600 mm (23.6 in) vertical, and the maximum workpiece weight is 1,200 kg (2,646 lb).
03
The maximum grinding wheel diameter is 500 mm (19.7 in) and the maximum width 100 mm (3.9 in). Maximum peripheral speed is 80 m/s, and the spindle driving it is listed at 37 kW (49.6 HP).
04
It is not in Blohm's current lineup. The listed figures are unconfirmed, so for a used machine confirm the dressing equipment fitted, the spindle rating and the control, listed as a Siemens 840D sl with the Blohm OP 15 interface.
