Overview
The Blohm Profimat MT is a family of table-type grinding machines in six sizes, from the MT 408 with a grinding range of 400 x 800 mm to the MT 620 with 600 x 2,000 mm. Every size shares one grinding spindle specification, listed as up to 60/8,000 kW/rpm, and takes a wheel of up to 500 x 200 x 127 (203.2) mm.
The sizes fall into two widths. MT 408 and MT 412 grind 400 x 800 mm and 400 x 1,200 mm on X travels of 900 mm and 1,300 mm, with 320 mm of Z. The four wider machines grind 600 x 800 mm (MT 608), 600 x 1,200 mm (MT 612), 600 x 1,600 mm (MT 616) and 600 x 2,000 mm (MT 620) on X travels of 900 mm, 1,300 mm, 1,700 mm and 2,100 mm, and all four have 520 mm of Z. The table clamping area is longer than the grinding range on every size, 400 x 1,200 mm on the MT 408 and 600 x 2,400 mm on the MT 620, which leaves room for dressing devices or fixtures beside the part.
Y is the vertical axis. Its 550 mm of travel matches the span of the distance from table to spindle center, 150 … 700 mm (optional 950), and the optional 800 of Y goes with the optional 950. Feed rates show what the axes are for: X runs from 15 … 25,000 mm/min, slow enough for a deep single pass and fast enough for reciprocating strokes, while Y is 4 … 3,750 mm/min and Z is 4 … 4,000 mm/min.
An overhead dresser with a V-axis stroke of 130 mm is listed as an option. Floor space starts at 3,500 mm wide by 4,500 mm deep for the MT 408 and reaches 5,900 mm by 4,700 mm for the MT 620, and machine weight runs from 6,500 kg to 8,000 kg.

Strengths & Limitations
Strengths
- Six sizes on one design, with grinding ranges from 400 x 800 mm (MT 408) to 600 x 2,000 mm (MT 620)
- Grinding spindle drive listed as up to 60/8,000 kW/rpm on every size
- Takes wheels up to 500 x 200 x 127 (203.2) mm, wide enough to carry a multi-form profile
- X feed rate of 15 … 25,000 mm/min covers slow deep passes and fast reciprocating strokes on the same axis
- Vertical travel of 550 mm can be ordered as an optional 800, with table-to-spindle distance rising to an optional 950
Limitations
- The overhead dresser, with its 130 mm V-axis stroke, is an option and not part of the base machine
- MT 408 and MT 412 have 320 mm of Z travel, against 520 mm on the four 600 mm wide sizes
- Even the shortest machines need 3,500 mm of width and 4,500 mm of depth; the MT 620 needs 5,900 mm by 4,700 mm
- The spindle figure is an upper limit (up to 60/8,000 kW/rpm), and the table does not say which drive a given size ships with

X travel is 900 mm on the MT 408 and MT 608, 1,300 mm on the MT 412 and MT 612, 1,700 mm on the MT 616 and 2,100 mm on the MT 620.
02
Y is the vertical axis, with 550 mm of travel and 800 as an option. The distance from table to spindle center is 150 … 700 mm (optional 950). Z is the cross axis: 320 mm on the MT 408 and MT 412, and 520 mm on the MT 608, MT 612, MT 616 and MT 620.
03
The table lists the grinding wheel size as up to 500 x 200 x 127 (203.2) mm and the grinding spindle drive as up to 60/8,000 kW/rpm, power and speed in that order. Both are upper limits, so confirm the drive and wheel mount quoted for the size you are buying.
04
Width by depth is 3,500 mm by 4,500 mm for the MT 408, 4,500 mm by 4,500 mm for the MT 412, 3,500 mm by 4,700 mm for the MT 608, 4,500 mm by 4,600 mm for the MT 612, 5,600 mm by 4,600 mm for the MT 616 and 5,900 mm by 4,700 mm for the MT 620.

05
No. The table marks the V-axis stroke of the overhead dresser, 130 mm, as optional. If your process depends on dressing the wheel from above while it stays in the cut, make sure that unit is on the quotation.
