How much does the Blohm Orbit 46 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
A 45 kW (60.3 HP) grinding spindle, coolant at up to 150 bar (2,175 psi) and an 800 mm (31.5 in) rotary table are the headline rows for the Blohm Orbit 46, which is listed as a 5-axis simultaneous grinding machine. The model is not in Blohm's current lineup. Treat the listed figures as unconfirmed and use them to frame questions about a used machine.
High spindle power and high-pressure coolant belong together. Deep, slow passes that remove a lot of stock generate heat along a long arc of contact, and coolant delivered at pressure is what keeps the wheel clean and the part from burning. A machine listed with both is set up for heavy stock removal rather than for light finishing alone.
The rotary table carries workpieces up to 500 mm (19.7 in) in diameter, 400 mm (15.7 in) high and 300 kg (661 lb). Travels are 800 mm (31.5 in) in X and 500 mm (19.7 in) in each of Y and Z; the A axis swivels ±120° and the C axis turns 360° continuously. Wheels up to 500 mm (19.7 in) in diameter run at a peripheral speed of up to 80 m/s.
Against the Orbit 36 the listed envelope is larger in every direction: the Orbit 36 is given 350 mm (13.8 in) of workpiece diameter, 250 mm (9.8 in) of height and 150 kg (330 lb), so the Orbit 46 doubles the weight limit. The base is polymer concrete of the Granitan type and the control is a Siemens 840D sl with the Blohm OP 15 interface.

Strengths & Limitations
Strengths
- 45 kW (60.3 HP) grinding spindle paired with coolant at up to 150 bar (2,175 psi)
- 800 mm (31.5 in) rotary table taking workpieces up to 500 mm (19.7 in) in diameter and 300 kg (661 lb)
- 5-axis simultaneous motion with ±120° of A swivel and 360° continuous C rotation
- Wheels up to 500 mm (19.7 in) in diameter at up to 80 m/s
- Twice the workpiece weight of the Orbit 36, which is listed at 150 kg (330 lb)
Limitations
- Workpiece height is limited to 400 mm (15.7 in) and weight to 300 kg (661 lb)
- Y and Z travel of 500 mm (19.7 in) match the maximum workpiece diameter, leaving no margin on a full-size part
- No rapid traverse, table speed or machine weight is listed
- Not in Blohm's current lineup, and the listed figures are unconfirmed

Frequently Asked Questions
01
The listed maximum workpiece is 500 mm (19.7 in) in diameter, 400 mm (15.7 in) high and 300 kg (661 lb), on a rotary table of 800 mm (31.5 in) diameter.
02
The grinding spindle is listed at 45 kW (60.3 HP) and coolant pressure at up to 150 bar (2,175 psi). The maximum wheel diameter is 500 mm (19.7 in) and the maximum peripheral speed 80 m/s.
03
The Orbit 36 is listed for workpieces up to 350 mm (13.8 in) in diameter and 150 kg (330 lb), with a 400 mm (15.7 in) maximum wheel. The Orbit 46 takes 500 mm (19.7 in) and 300 kg (661 lb), with a 500 mm (19.7 in) wheel.
04
No. It is not in Blohm's current lineup, so only used machines will be on offer, and the listed figures are unconfirmed. Ask for the machine's documentation and check the spindle rating, the coolant system and the travels against it.
