Molly™ F165 Walzwerk

Unfortunately it is not possible to add side extensions to a Rolling Mill. Please consider this if you are looking to purchase a new rolling mill and what your current and future requirements may be. 

It is possible to use two half round extensions if your rolling mills supports extension rollers but you will need to re-order the 2 extension rolls together and inform us that they are to match, this way we can machine them as a matching pair.

Please note: You will not get perfect round with this solution. It will be oval shaped. 

A rolling mill with no reduction (direct drive) means that when you turn the handle round once the rolls go round once.

A Rolling mill with reduction (with gearbox), let's say 4-1 means you will have to turn the handle four times for the rolls to go round once.  A reduction of 5-1 means you must turn the handle five times for the rolls to go round once. Having a reduction gearbox makes lighter work of rolling.

Direct Drive means there is no gearbox on the rolling mill, the handle is linked directly to the rollers with no reduction.

If the model number has an "R" then it has a Reduction Box

If the mode number has an "E" It means there are side extensions

If the model number has "RE" then it has a reduction gearbox and side extensions

Unfortunately, reduction gearboxes cannot be added retrospectively.

Unfortunately, it is not possible to change a manual rolling mill to a powered rolling mill.

For the Rolls, the best oil to use is ‘3-in-1’’ oil to protect your rolls, apply layer with a cloth after use or regularly if not in use for long periods of time.

For the gears, we use lithium soap thickened grease when we are making the mills, but any standard gear grease can be used.

Sometimes the rollers do develop marks, but it will not affect the use of your mill at all and it will still work perfectly.

The Agile mills have a T bar instead of a handwheel and do not have extension rollers. The Agile mills also have additional half rounds on the main roll so it has less flat area.

DRM Walzwerke have the round adjustment wheel, optional side extensions (E Models) and different roll / groove options. 

Other than these differences, the mills are the same and offer the same performance.

Yes we do keep some spares for older generation Durston Walzwerke

Generally, the minimum – maximum thickness is 0.1mm – 6mm

How thin can your mills roll material?
As a rough guide divide the diameter of the roll by 750.
For example, on Agile 110 the diameter is 50mm so 50 divided by 750 is 0.66mm
In fact, you can divide it by between 500 to 1000.
It depends on the width of material and the hardness but dividing by 500 to 1000 gives a good idea.
So basically, you can roll down to between 0.50 and 0.1mm depending on hardness.
If it is 30mm wide, then it might go to 0.1mm
If material is 10mm wide and soft it will roll down to .05mm

The turning lever is 35cm from the centre of the hole where it attaches to the mill to the end of the handle.

The dial is just a guide and does not provide exact measurements.

The best way to minimise is, do not roll with rolls closed. Have them open approximately 0.3mm and turn the wire 90 degrees on each pass.

When the rolling mill is not in use, apply a thin coating of rust preventative liquid. Using a clean and dry paint brush (approximately 12mm wide) apply the rust preventative across the rolls. Turn the rolls as you do this. Make sure the rolls are nearly closed. This will spread the liquid evenly over the surface. It is very important that your rolls are always protected, especially in moist/wet/hot conditions or where temperatures are changing. Once your rolls are marked/rusty/corroded they will be like this until you have them removed and reground. (However, please note that it is almost impossible that you will end up with perfect rolls. Over time and use they will get slightly marked but will still work perfectly well). When using your mill again remove all rust preventative and ensure your rolls are clean and dry before you start to roll material.
It is also recommended that you cover your mill when not in use. This is to prevent the rust preventative from collecting dust and dirt.
Keep the rolls clean. Do not touch the rolls. Oils and acids from your body can damage the rolls, leaving behind small marks and eventually
rust.
Make sure all material is dry before rolling.
