Frequently Asked Questions - KD-Y7648 Vevor

How to adjust the gap between rollers?

Use the T-handle on top: turn clockwise to lower the top roller (reduce gap), counterclockwise to increase it. Half-turn per pass is recommended.

What metals can be rolled with this rolling mill?

This rolling mill is designed for ductile metals such as gold, silver, copper, aluminum and their alloys. Do not roll hardened steel.

How to make square wire?

Use the V-grooves. Pass the metal through the rolling mill, turn it 90°, then pass it again. Continue by reducing the gap by half-turn each time. The metal will become a square bar.

What to do if the metal becomes hard to roll?

The metal hardens during rolling. It needs to be annealed: heat it to dull red, hold for one minute, then quench in water or let cool. This will make it softer.

How to emboss a pattern on a sheet?

Create a sandwich: metal sheet (pattern side up), texturing element (lace, wire), then a protective sheet (copper or brass). Pass everything through the rollers with light pressure (1/2 turn).

How to maintain the rollers?

After use, wipe the rollers with a lightly oiled cloth to prevent rust. Store the rolling mill with rollers separated. If marks appear, hand polish with an anti-rust product.

What is the maximum opening capacity?

The maximum opening between rollers is 7 mm.

Do I need to lubricate the machine regularly?

Yes, oil all moving parts (rings, gears) regularly. The gearbox requires no special maintenance. Apply grease around the rings while closing/opening the rollers.

Can multiple pieces be rolled at once?

It is recommended to roll only one piece at a time to avoid accidents and ensure uniform thickness.

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 roller moves down; the bottom roller remains fixed. Turning the T-bar clockwise (as viewed 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 the 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° 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, but this will be less noticeable. If you rotate it 90° after each pass, it will go 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. Starting with the again, follow the same method of rolling the wire through, rotate 90° and 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 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 to harden it. 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 it 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. Rotati

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 Shared Wire: When using the fat/oval section of the combination, you can make a D profile wire for ring shanks, etc. Start with a well-squared 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 silver. Above it is a scrap sheet of copper or brass. This will protect your rollers. For 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 oiled. If the unit is to be unused for a long period of time, oil all parts thoroughly, cover it, and ensure it is kept dry and free from moisture.
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 for this. 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 removed by hand using a cloth and car metal polish such as rust remover. Emery paper and oil can be used (if absolutely necessary) to remove superficial marks, but generally harsh abrasives should always be avoided. 4. The unit is designed for jewellery use with precious and nonferrous 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 made.

are dry 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.
