Now Here! GDP CNC TOOLING GUIDE!

At GDP|GUHDO, we have put our resources together to provide a comprehensive CNC Tooling Guide. This guide is designed to provide the knowledge to support the most efficient use of your CNC tooling.  We want to put the information into your hands any way that you can use it, so we also have a downloadable link to a PDF version of the presentation here.

Below is a directory for both the video presentation and the PDF presentation.

Tooling for Alucobond

 From buildingindustry.org

Alucobond is a type of sandwich panel which was first introduced in 1969 and is now widely used in the residential and commercial construction industries. This ACM, (aluminum composite material) consists of two sheets of smooth 0.02” aluminum, thermobonded to a polyethylene core. The result is a light composite material that offers many benefits including perfect flatness, rigidity, weatherproofing, impact resistance and also features vibration dampening characteristics. These characteristics make this product truly unique and popular and it’s available in a wide variety of colors and textures.

 While standard tooling may be utilized,  you may find it a bit challenging.   We offer specific tooling for machining this unique product. For sawing, we offer a line of saw blades specifically engineered for quality results in terms of finish quality and extended tool life. These saw blades are designed for use on horizontal, vertical and most table saws and are available in sizes ranging from 250 mm up to 550 mm.

For folding applications, a “V-grooving” cutter head is available in two variations, 90 and 135 degree. This specialty cutter head is designed to be used on CNC aggregates, panel, vertical or table saws.  For CNC routing applications, a 90 and 135 degree profile router bit is also available for folding applications. These tools are specifically engineered to be used on Alucobond or similar products and will produce excellent results.

Keys to Cost Savings while Machining Solid Surface Material

At GDP|GUHDO we strive to help our customers optimize cutting tool performance and cost – we recently contributed this article to the ISFA (International Surface Fabricators Association)  for the Q4 2014 issue of Countertop & Architectural Surfaces Magazine .

Keys to Cost Savings while Machining Solid Surface Material

While the homogeneous composition of solid surface material doesn’t generally pose particular machining challenges, there are great ways to reduce your overall tooling expense, increase tool life, improve finish, reduce down-time and maintain a smoother work flow by selecting the correct cutting tool for the application.

Whether tooling is needed for use on a hand-router at installation site or production tooling in the shop, options available to streamline production, reduce down time, eliminate sanding and cut cost are overlooked all too often.

While most saw blades look similar, on closer inspection there are marked differences in tooth design/grind, angle and tooth count that affect the quality of cut and how long the blade will perform well before getting dull. These differences in tooth geometries are the result of much research and testing, to accommodate the wide range of materials and composite panels that all present their own unique cutting characteristics. For cutting solid surface material, the tooth design that provides the longest, cleanest cutting performance is (more…)

Drill Bits

PCD (polycrystalline diamond) dowel bit

While metric dimension drill bits all look quite similar to the untrained eye, there are differences in style, design and material quality that have a clear impact on tool performance, cost and your bottom line. About 20 years ago, carbide-tipped drill bits, previously manufactured for the most part in Germany and Italy, were largely replaced by the “invasion” of Chinese and Taiwanese bits offered at a 30-40% reduction in price. The adage, “you get what you pay for“, applies here just like everywhere else in life.

While the initial cost of the bit goes down, production costs actually go up as a result of shorter tool life, lower quality of edge, increase in tool changes and more panel rejects. The difference between a Taiwanese and German drill bit is quite noticeable as the German bit has a faster twist which results in quicker chip evacuation, less heat and thus, longer life, not to mention better engineering of clearance angles and tip geometry which impacts the finish quality of the cut. The German bit is King in solving applications that are prone to problems, such as laminated “disks” getting stuck in the dowel point, irregular (egg-shaped) holes, burning, premature wear and edge chipping on the hole.

Solid carbide drills have also gained popularity and are available in several of the more popular diameters. For those seeking the ultimate in quality and unbeatable performance, PCD (polycrystalline diamond) drill bits have made their debut and are the standard for composite materials! While the diamond drill bits are limited to certain sizes, they are available in Dowel, Through Hole (V-Point) and Hinge style with overall lengths of 57 and 70 mm. These high performance drill bits are ideal for drilling abrasive materials including MDF, particle board, laminates, fire resistant boards or gypsum based materials. So, if you haven’t given much thought to your drill bits, perhaps it’s time to consider the options? Interested? You can contact us and we are happy to help!
