My machining experiences between 7075 Aluminum and Gun metal bronze to the Juntor watch

Gun metal juntor machining experiences   What a beginner most afraid when starts to machining are three things, the sound, the smoke and the sparks of the contact of the tool with the work material. With respect to sparks, when using titanium or magnesium alloys there is a great danger of ignition, which means that apprehension to them must be watchful. In any case, that is no problem in the aluminum and bronze alloys that we currently use in the Juntor. Although in the old Juntor we use alloys of steel, titanium or bronze to aluminum, we are now opting for aluminum and bronze alloys of tin called Gun metal, since the current Juntor has a marked tactical component. Loud sound in machining appears when cutter has a large diameter. This is because cutting surface increases. So cutting deeper, faster and more feed surface of the workpiece on each step sound increases. If the beginner is not get used, it will seem that the machine bursts. For veterans this sound is a music to their ears. At the beginning I recognize that I was very afraid to machining. Now the sounds helps me to know that I have to decrease the cutting speed or change the milling cutter. Smoke is exactly the same. It frightens when you do not know what the matter is. It happened a couple of times because I measured wrong tool length. With excessive friction of the tool to the metal in the area without cutting. That is a big problem when machined brass because it can change the color of the piece and darker. If...
New packaging project in EXT LAB

New packaging project in EXT LAB

We have started to develop a new pack for Juntor watch. This pack is made from propylene material. It is made by machining with a flange in order to mechanic retention. As well, it has a internal support to keep the watch in the same position. It should withstand all kind of movements on the delivery. This pack is designed, developed and made in our workshop, in Alcoy...
We should recover the private area for EXT customers

We should recover the private area for EXT customers

We should recover the private area for EXT customers.   In 2006, when we introduced our website we developed a private area for our customers. The clients could access directly from the our website and it included several sections: – Guarantee: Clients had access to the conditions of the guarantee and the expiration date. – Contract: Included the technical specifications of the EXT watch acquired and he could download the invoice if required. -Technical service:  Customers could contact directly with our technical service, creating a notifications history, like o-ring changes, new straps, bezels of different colors, etc. – Newsletter: EXT customers received a quarterly newsletter about our unique way of feeling time. – Notifications: A notifications history for each customer to the brand or us to them. – Forum: EXT customers from around the world could be in touch with each other through a forum relationship.  They could participate in various topics related to time or the way we live life in Spain. – Merchandising: Customers could acquire different accessories like straps, links, bezels, shirts or glasses. By that time we found it a very attractive idea, because if a customer pays a high price for a watch, likes to have an interaction with the company. Unfortunately the area was not successful at all. We thought that the problem was that the idea was very ahead of its time. Now that social networks and the Internet are booming, this private space should be recovered again. As well, we are ready to make things, we consider that this is the moment to re-start  this area. We realized that there are a lot of posts explaining this idea, looking for an added value to a product. We were...
Juntor sketch from vector file

Juntor sketch from vector file

  When I want to improve a watch introduction, I use 2 tricks to do it. First, I make the watch in Fusion 360 and I get vector file like PDF or DXF. From that I import the file in Sketchbook in order to get color, highlights, ground etc. Second, I can open this file in photoshop in order to sketch new shapes like arrows or give more contrast if I consider it necessary In this sketch I have just introduced a view but I can make 3 or 4 even making an exploratory sketch of small...
Juntor strap mold. Other innovation we have introduced

Juntor strap mold. Other innovation we have introduced

Going on with our innovations we are going to introduce the polypropylene strap mold. The advantages that this kind of material is that we can machine it very fast. So we can make customize mold strap because we use cast polyurethane for strap. Polyurethane has better propierties than natural rubber for strap watches. Moreover is a advanced material is a lot of thing like sport shoes. Polyurethane is not injected, it just filled in the mold and it is closed with some screws. We put the mold in a oven to 90º for some hours in order to cure the material easier. When the part is finished the edges are deburred the and polished it. This strap can be made in different colors ans sizes because the customization allows it....
