It is a wide spread practice to use cup wheels for working on edges, as these have the advantage of wearing out very evenly and therefore there is no necessity to have them reprofiled. There are diamond cup wheels with diameters varying from 75 to 250 mm. The wheels need to have different bores according to the type of machine being used; the height of the wheels differs also. We can provide wheels for all known brands.
Diamond wheels in metal bonding have a good stability, offer a variable amount of abrasion and good grinding performance combined with short machine processing times. According to the required type of machine and task these tools can be manufactured with varying abrasion resistance of the bonding. Usually diamond wheels are distinguished by the type of diamond coating: continuous band (homogeneous), open segmented or closed segmented and varying abrasion levels. These tools are especially suitable for thinner types of glass and mirrors (continuous band) and for thick window glass and laminated safety glass and mitre grinding (with open or closed segments).
Resin bonding has the advantage of an excellent operating speed combined with a high grinding quality. These tools can be provided with continuous band as well as open segmented or closed segmented. According to the required task, the grades can vary tremendously (for bevel grinding you would use a softer variety whereas for working on a double-edger a very hard type with a long wheel life would be more suitable).
As with the afore mentioned cup wheels peripheral wheels can also be manufactured in either metal or resin bonding. You can choose between continuous band/rim or segmented wheels. In addition they can be provided with a water passage.
Every possible profile may be incorporated into the diamond coating – e.g. trapezoidal edge, pencil-edge, cylindrical profile, OG-edge, waterfall edge, bull nose, mitring profile, fluted bevel, step shapes and many more... Peripheral wheels can be manufactured with diameters varying from 10 mm up to 250 mm.
For simple glass edges working with a pencil-edge wheel is still a very effective way of processing, especially for glass used in furniture, glasses in vehicles and in the solar industry. These wheels can be produced with varying diamond grades according to your requirements.
Numerous technically advanced products are nowadays supplied with a trapezoidal profile. The depth of the diamond section can be manufactured to the standard you require.
Modern machine centres require an extensive range of tools, radii are ever decreasing whereas the quality of edges is supposed to be improving further. We can supply the suitable tools for these demands with bore holders or R1/2“ drill point holders according to the cone holder of your machine.
The bore of 22 mm has become standard over the previous years, nevertheless other sizes e.g. 12 mm, 25 mm, 48 mm, 50 mm and 60 mm are also being used today. According to your requirements these wheels can be manufactured with continuous band or segmented and with water passage. The standard wheels have usually an outer diameter of 40 mm up to 200 mm.
This holder has been in wide spread use for many years in diamond core drill bits. The thread with a cone enables you to tighten the tools while at the same time centring them. All tools have been designed to let the coolant emulsion flow through the tool. This way even a high spindle speed will not stop the water flow. This range of tools contains conventional milling cutters, milling cutters for operating on edges, diamond core drill bits, diamond core drill bits with countersink, countersinks and tools for operating on edges with small radii. Engravings can be done also.
We supply diamond core drill bits and countersinks with different lengths so they can be fitted to all machines used worldwide. The diamond core drill bits are available in lengths of 75 mm and 95 mm. There are similar lenghts for counter sinks and special grinding tools for drills and steel base milling machines. Usually we provide these with an R1/2“ thread that also centres them; but there are varieties with a cylindrical holder or a different sort of thread.
Diamond core drill bits can be provided by us in different variations; usually we supply these drill bits with a highly compressed sintered diamond coating. Certain operating procedures require the use of drill bits with slots. The base of our diamond core drill bits is made of corrosion resistant brass. We also supply dressing sticks; using these the worn coating can be removed and a new layer with diamonds appears.
Milling tools have been developed for working on glass surfaces. According to the thickness of the glass we recommend these products with varying numbers of segments and also with medium or coarse grit sizes. For minute radii there are so called finger milling cutters with diameters from 4,5 mm to 9,0 mm available. By using multi-purpose tools the setting up time can be reduced. These milling cutters can be used for milling and also grinding.
To save time diamond core drill bits with countersinks can be used. This countersink can be attached to the diamond core drill bit and is adjustable to the required depth. For extreme sinking we would recommend the segmented variety of the countersink. Using this will enable you to cleanly add a deeper sinking to your bore.
Tools that are used for processing glass in different sizes every day sometimes need to be reprofiled or regrinded respectively. This frequently applies to peripheral wheels and also countersinks and in some cases cup wheels. We can offer to clean your tools, redress them or adjust the profile to the correct shape.
In February 2002 Michael Contreras decided to found DIACON + POLICON TOOLS®. After 18 years work experience and knowledge of the trade (sales department and technical advice) working for a well known German manufacturer of glass processing machines (Bodo Gerhard G-B-M GmbH, Celle) it was impossible to turn the back on the glass trade. All the contacts over the years have been too positive and friendly.
Immediately some manufacturers of tools decided to assign us the right of sale for Germany and other German speaking areas due to our competence. We would especially like to thank the following companies: Mole Moreschi from Italy, Marrose Abrasives from the United Kingdom and Dogo, also from Italy, as we have cooperated with them right from the beginning
We are capable of offering you the most efficient products for the best price. Our renowned suppliers provide good and efficient quality products made in EU-countries. Approximately 400 customers regularly buy from us and get our advice – because our experience and competence has convinced them.
Today we can offer the complete range of tools for grinding, milling, drilling, sawing and polishing for the glass processing trade. Right from the start it was important to us to offer our customers a service for everything on grinding and polishing of glass from one source.
In Winsen/Aller we maintain our own warehouse; we also have access to our business partners stock via internet. The shipment is usually done with UPS. Once a year we attend an international trade fair, where we can show you our business associates products and explain them to you. These fairs are Glasstec in Düsseldorf/Germany and Vitrum in Milan/Italy.
There is a wide selection of diamond tools available today for effectively processing flat glass. As your supplier we can offer you an extensive range of precision tools for different stages of processing, such as cup wheels or peripheral wheels, CNC-processing wheels with bore holder or R1/2“ drill point holder, diamond core drill bits, counter sinks, milling cutters or saw blades. The diamonds are incorporated in various bonding (metal sinter, resin or galvanic). For this bonding we can provide suitable dressing sticks.
Our polishing wheels enable you to polish the glass edges on your machines perfectly. We can provide the right wheels for every possible task. Our competent suppliers have specialised on the production of cup wheels and peripheral wheels. The wheels can be obtained as a ring for glueing or as a cup wheel or peripheral wheel, whichever you prefer. At present we can supply wheels with a diameter of 18 mm up to 250 mm.
Cup wheels have proved themselves on vertical grinders and double-edge grinders for years. They are produced with a diameter of 75 mm up to 170 mm. We supply them with different types of bores according to the machine requirements. Some cup wheels can be ordered with a reinforced base plate on demand. These cup wheels last longer and remain torsionfree underneath the glass edge; therefore the glass edge can be worked on in the best possible way.
Usually we can supply the so called rubber bonding in grit sizes 40, 46, 60, 80, 120 and 180. These wheels provide an excellent pre-polishing result. According to the type of machine and thickness of glass the wheels may be fitted individually.
Cup wheels in resin bonding are nearly always used for the arris. These wheels produce an exact arris, which does not polish the surface. According to your requests there are wheels in the shape of an arris cup wheel that simultaneously grind and polish by using a coarser type of grit or a different sort of wheel which is solely for the fine polishing process after the grinding (very fine grit).
Cerium wheels are meant to give the preground glass a high gloss finish. There are different polishing wheels containing varying amounts of cerium oxyd (rare earths) available. The spindle speed of your machine always needs to be taken into consideration.
The best high gloss finish is received by using felt wheels in conjunction with cerium powder dissolved in a water emulsion. This technique is absolutely necessary for bevelling and increasingly for high quality edging. We can provide cerium powder in different varieties in packages of 25 kg.
Peripheral wheels can be supplied with the same bonding and varieties as our cup wheels. As a customer you can choose the size (Ø), thickness or breadth and the bore in order to get exactly the right tools for your requirements. For double-edge grinding plants usually long lasting rubber bonds are the best choice, but a polish with cerium is also possible. Especially for CNC centres we can recommend so called ´BD wheels´, easily recognized by their red-brown colour. This sort of wheel will give a good to excellent polishing result in connection with a varying spindle speed.
For certain types of glass edges, e.g. 45°-bevel and fluted bevel we supply preprofiled polishing wheels that are able to start working on the edge immediately and are very cost effectively. There is no need for your staff to laboriously prepare the required profile beforehand. You can also order the ´simpler´ types of edge profiles in a preprofiled variety. The wheels may be used straightaway without any time consuming preparations.
When coated glass (e.g. Low-E) is used for processing insulated glass, the coating/sputtering of the edges of the glass surface must be removed. This is done with a specially rubberized grinding wheel in varying grits (46 – 150) and sizes (Ø). We can supply the appropriate deletion wheels for your machines.
