Muller BEM crankshaft grinders

Muller BEM crankshaft grinders 

CranI shaft grinders machinesType R grínders can be brolcen down into two main ranges, one of whích compríses MECHANICALLY CONTROLLED MACHINES and the other HYDRAULICALLY CONTROLLED MACHINES.
Within each range, there are various models charact : ised by theír world capacities : distance between centres BC and centre heíght CH .
MECHANICALLY CONTROLLED MACHINES
Equipped with table and grinding wheel head rapid feeds, these grinders are especíally
robust and easy to handle under widely varying operating conditions.
R 2200/270 : вc -= 2 200 cн 270
This machine is designed for grinding passenger, utility vehicle and commercial
vehicle crankshafts.
Many accessories permit its adaptation for the widest possible range of different
types of work and changing from one operation to another is extremely quick and easy.
R 2200 f 350 : BC -- 2 200 CH -- 350
This grinder has the same specifications as the one above but its higher centre
height permits one to use an eccentric plate 600 mm in diameter and this makes
it particularly well suited to grindiiıg Iarge throw crankshafts.
HYDRAULICALLY CONTROLLED MACHINES
This type of grinder is easy to use by virtue of its hydraulic controls and its high
repeatability accuracy plunge cut system together with the continuous variation in
the speed of the workpiece.
R 1250 H PG : BC - 1 250 CH =- 270
A high performance machine for grinding passenger and utility vehicle crankshafts in small batches. This machine can be equipped with a wide range of accessoríes intended for small batch production work. Monitoring drum, roller type wheel
dressing etc.
R 2200 HNG : 
Although it has the same centre height as the above machine, its larger capacity between centres makes this grinder specially adapted for passenger, utility and
commercial vehícle crankshafts.
R 2200 HSG : BC 2 200 cн = 350
The same capacity between centres as the above model but with a centre height
of 350 mm so that it can be used with a 600 mm diameter eccentric plate which
makes it particularly useful for large throw crankshafts used on stationary engines,
compressors etc.
R 2500 HSG : BC 2 500 CH 350
The capacity of 2 500 mm between centres on this machine, with a centre height
of 350 mm makes it suitable for grinding very large crankshafts for heavy vehicles,
marine engines and earth moving equipment. Despite its size, this grinder sti11
retains a high degree of handleability, even when subjected to heavy loads.
On specíál õrder, we can supply--tMís grinder ицtha between centres capacity of 3000 mın.
MECHANICALLY CONTROLLE SPECIFICATIONS :
Bed : stabílísed cast íron. Ground slideways protected by cover plates and bellows.
Table : mechanícally operated wíth two automatíc speeds and a rapíd advance feed. Manual teed by means of a hand wheel.
Grindíng wheel head : manually operated plunge cut with rapíd approach and withdrawal.
Workpíece head : rack operated.
Spindle mounted on needle bearíngs.
4 rotatíng speeds.
Eccentríc plate wíth centeríng system in both planes.
Quick settíng balance slídes mounted outside the heads.
Electrícal swítch case : 220 380 V three phase feed.
24 V monítoríng and control círcuíts.
Equipment ín líne wíth current safety legíslatíon.
Centralísed lubricatíon system.
Safety systems :
When the grínder ís started the gríndíng wheel head automatícally moves backwards to commence the normal grinding cycle.
Absolute priority ís given to the return movement of the grinding wheel head ín case of inadvertent íncorrect operatíon or an unexpected temporary breakdown in the
current supply.
Safety system which only permíts the rapíd feed movement on the table to be used when the grínding wheel head ís ín the withdrawn posítion.
Safety system preventíng coolant beíng sprayed on to the grindíng wheel when ít ís not rotatíng.
