Frequently Asked Questions - KD-Y7548 Vevor

How to adjust the gap between rollers?

Turn the T-bar on top: clockwise to lower the upper roller (reduce gap), counterclockwise to raise it (increase gap). Only the upper roller moves.

What metals can be rolled with this rolling mill?

Ductile metals like gold, silver, copper, aluminum. Do not use hardened steel as it may damage the rollers.

How to make square wire?

Use the V-grooves. Start with a ingot, pass it through the mill, turn it 90°, pass it again. Reduce thickness by half a turn of the T-bar each pass. Then gradually move to the V-grooves.

What is annealing and how to do it?

Annealing softens metal after work hardening. Heat the metal to a dull red temperature, hold for one minute, then quench in water or air cool. Repeat if necessary.

How to avoid metal pinching during rolling?

Work slowly and gradually. Reduce thickness by quarter turns and pass the metal several times while turning it. Use a marker to track orientation.

Can I texture my jewelry with this rolling mill?

Yes, using the flat part of the rollers. Place a sandwich: metal to texture (face up), texturing element (face down), then a sheet of copper or brass as shield. Pass it all between the rollers.

How to maintain the rolling mill?

Regularly oil all moving parts and rollers with an oil-soaked cloth. Store the device in a dry place, rollers separated. For the gearbox, apply grease around the rings without disassembling.

What are the essential safety precautions?

Wear safety glasses, tie up hair, wear fitted clothing, keep children away. Check condition of parts before use. Do not use if tired or under influence.

How to create a D-profile wire?

Use the thick/oval section of the combination roller. Start with an annealed square wire slightly narrower than the groove. Pass it progressively in several passes to dome the top surface.

What to do if the rollers have marks?

Polish by hand with a cloth and metal polishing compound. If necessary, use very fine emery paper with oil. Avoid aggressive abrasives. In case of severe damage, roller replacement may be necessary.

OPERATION

1. The T-bar on the mill top is used to lower or raise the top roller, adjusting the distance between the two rollers. Note that only the top one moves down, and the bottom roller remains fixed. Turning the T-bar clockwise (looked down from above) will lower the top roller and reduce the gap, resulting in thinner wire or sheet. Turning the T-bar anticlockwise will lift the top roller, increasing the gap for thicker material.

1. In normal operation, you begin by opening up the rollers and inserting metal to be reduced. Turn the T-bar to lower the top roller until it touches the metal. Remove your metal and turn the T-bar a further 1/2 turn. Re-insert the metal and crank the handle, so that the roller turns inwards and grabs your metal, rolling it through away from you. Continue to turn the T-bar 1/2 a turn before each pass and this will slowly reduce the thickness of your material. Depending on the effect you want, you may wish to rotate your metal 90 degrees in order to create square or rectangular bars.

NOTE: When you reduce the thickness of your metal, it will typically increase in length quite dramatically. You may also see a slight increase in width, this will be less noticeable. If you rotate after 90 degrees each pass, it will go thinner and longer. Consider this when cutting or casting your initial starting piece.

1. Make square wire using the V grooves. It is first important that your material is uniform and parallel. Starting from the cast ingot, roll it through the machine, rotate the material 90 degrees, then roll it through the machine again. Note: Each time the T-shaped rod rotates half a turn, allowing the top shaft to descend, and rolling the material through. After rotating the material 90 degrees, roll it through once more. This dual-channel process will shape the material into a square bar.
2. As soon as it fits, move on to the V-groove rollers. Start with the large one again, following the same method of rolling the wire through, rotate 90° and pass through again. You may find it helpful to use a permanent marker to mark the side of the metal so you can see which way you are rotating it. When the rollers are getting close together, reduce the thickness by 1/4 turn and put the wire through several times, rotating each time before reducing any further. This will avoid any pinching as the rollers touch. Continue down to the roller until you have the desired dimensions. Note that the length will increase greatly during this operation. A small ingot a couple of inches can be transformed into many feet of thin wire.

TIPS AND TRICKS

ANNEALING: As the metal is forced through the rollers and transformed, it will work-harden. When your material becomes hard to roll or feels stiff, it should be annealed. Annealing is the process of softening metal and reducing its stress, making it more pliable. If you are not already familiar with it, it is advisable to check the best method to anneal the metal you are working with. Usually this is done by heating it gently to a dull red heat, maintaining that for a minute or so, and then quenching it in water or leaving it to cool. This makes the metal more pliable, easier to work with, and less likely to crack. When working an ingot down into wire, you may need to anneal several times during this process. Tip: Work on several separate pieces at once. So, when one is heating or cooling, you can roll another.

NOTE: Always ensure your metal is dry before taking it through the rollers to avoid any moisture on the rollers.

Creating Perfect Edges: Work your metal slowly and gradually. Rotate

as you go. Forcing the metal through in one direction with too much pressure can cause it to "pinch" the sides, creating thin and sharp edges. If this happens, rub the metal with emery paper to remove the edges (wear leather gloves). And pass it through the roller several times with the edge pointing upwards in the V groove.

D-Shaped Wire: When using the flat/oval section of the combination roller, you can make a D-profile wire for ring shanks, etc. Start with a well-annealed square wire a little narrower than the groove and gradually roll the width through in several passes to dome the top surface.

EMBOSSING TIPS

1. Almost anything can be embossed into precious metal and non-ferrous metals, such as lace, leaves, fabric, paper cut-outs, wire, etc. This technique can be used to add interesting textures to your jewellery. However, you don't want to damage your rollers by embedding a pattern into the steel. For this reason, it is vitally important that you use a sacrificial piece of metal as a shield between your texturing item and the rollers.

1. Create a sandwich as shown: On the bottom is your metal, flat and well annealed, e.g. silver sheet. The uppermost face will be embossed. On top of it is the item to be embossed, e.g. a leaf or loops of wire (here). The side you want embossed should be face down onto the metal. Above it is a scrap sheet of copper or brass. This will protect your rollers. Use soft metals, do not use steel, as this may scratch your rollers. This is referred to as scrap; the pattern will also be embossed onto the scrap sheet, so some interesting results can be obtained. But usually, this is a piece of flat scrap metal, which can be reused as a shield. Ensure the shield is larger than the silver to avoid embossing the edges into your silver.
2. Ensure that the sandwich is only passed through the flat part of the rollers. Passing it through the V rollers will leave flat parallel lines on the underside of your silver.
3. Place the sandwich between the rollers and lower the top roller until the sandwich is snug between them. Remove the sandwich and turn the handle 1/2 a turn or a little less. Pass the material through and this will provide enough pressure to emboss the item into the silver.

MAINTENANCE

Your rolling mill is a very robust piece of equipment and should give years of service. As with any mechanical item, a little maintenance will keep it in optimum condition for the best possible performance.

1. Oil All Moving Parts: It is important that the rollers do not become rusted, so be aware of condensation in damp areas. Wipe the rollers with a light coat of oil on a cotton cloth and store the mill with the rollers covered, ensuring it is kept dry and free from moisture. If the unit is to be unused for a long period of time, oil all parts thoroughly.
2. The gearbox should not require any special maintenance. Inside the frame, where the bushes move up and down, will benefit from a little grease or oil, but there is no need to dismantle any part of the unit. Simply close the rollers to apply grease around the bushes, then fully open and close several times to move the grease.
3. If the rollers obtain any superficial marks or stains, they can be polished by hand using a cloth and car metal polish such as rust remover. Very fine emery paper and oil can be used (if absolutely necessary) to remove superficial marks, but generally harsh abrasives should always be avoided.
4. 4. The unit is designed for jewellery use with precious and non-ferrous metals. Do not attempt to roll hardened steel, as this may damage the

rollers. When annealing and pickling metal, always ensure that all items are dried thoroughly before passing through the rollers. After a busy day of extensive use, a quick clean and wipe of oil on the rollers will be beneficial. Develop good working habits, look after your mill and it will provide years of service.

1. If the surfaces of the rollers become damaged through improper use, this may require replacement of the rollers, which may incur a cost.
