If so, GUHDO offers our 6365 Series collet chuck specifically designed for the ETP clamping system.  This high precision chuck is produced with the required 25 mm shank and adjustment screw and is designed to accept standard RDO 20 (407 E) collets for shank diameters up to ½”. 

Using only the highest quality materials ensures the highest levels of precision and the tool body is tempered, ground and thoroughly balanced.  Interested in more information? Give us a call at 1-800-544-8436 or contact us now!

Precision CNC Boring Drill Chuck

6380 Series Universal CNC Boring Chuck - HSK Style

6380 Series Universal CNC Boring Chuck – HSK Style

The 6380 Series Universal CNC Boring Chuck is designed to clamp precision drill and boring bits with high clamping power and accuracy.  When it comes to clamping, the 6380 Series utilizes a Jacobs chuck clamping system, offering superior concentricity with a maximum tolerance of 0.02mm (.0008″) at a 35mm drill length, extending from the output. Drill bits with a flat on the shank are not a problem either.  Flat shanks are clamped accurately and tightly provided the flat portion of the shank is positioned between 2 of the 3 clamping jaws as seen in the picture below. A minimum clamping depth into the adapter of 20mm is required.

The Continuing Evolution of Diamond (PCD) Cutting Tools

The Continuing Evolution of Diamond (PCD) Cutting Tools:

In the summer of 1982, when the International Woodworking Fair (IWF) made its debut show in Atlanta, GA, the first polycrystalline diamond tools for wood/composite material were introduced in the U.S. The promise they brought ….to run up to one million feet of material without a single tool change, seemed inconceivable and no one could fathom that any cutting tool could continuously run the equivalent of 7+ marathons (over 180 miles) cutting abrasive particleboard without wearing out on the first 10 miles!

High-tech panel production equipment coupled with competition among cutting tool manufacturers has earned a handsome dividend for panel processorsgiga cutter, allowing manufacturing costs to stabilize. As diamond tooling evolves, developments include extreme axial shear angle cutters that achieve a satin smooth finish resulting from a cutting action that is closer to shaving or peeling, rather than cutting. While these cutters are ideal for peripheral cuts, they aren’t the solution for parting cuts due to the larger cutting diameter necessitated by the extreme axial shear and resulting yield inefficiencies.

Hogging/panel sizing cutters continue to advance with interesting designs that incorporate dust flow and chip extraction features along with lighter overall tool weight (to reduce injury risk during tool changes) and tooth geometries that are matched to specific application for best finish.

The continuing advancement of newer composite panel materials, whether lightweight honeycomb panels with aluminum skin, wood composite panels with highly abrasive laminate surface, fire rated MDF, carbon fiber reinforced plastics, phenolics or other PCD Hoggerspecialty materials, each seem to present their own set of unique challenges to efficiently cut, profile and optimize tool life while obtaining a quality surface finish. These challenges keep design and implementation of new cutting tool engineering ideas at the forefront and this trend will continue.

Diamond-tipped saw blades deliver great savings during the many months they run without garnering even a moment of attention until they become dull! PCD saw blades do best and perform the longest in homogeneous materials, such as solid surface material, wallboard, hardboard, cement fiber board, MDF and similar materials.

FourcutDiamond router bits have progressed as well. Chip load is the most important factor in seeing positive performance, so, the once popular disposable diamond router bit, that has definite feed speed limitations, has taken back seat to newer designs. It is important to review expectations for output, finish and performance when determining the tool specifications. The choice of single, two or three flute, straight or shear, segmented, staggered, insert or solid PCD tip, diamond grade (coarse or fine), polished or not should all play a part in the decision for best results.

Drill bitsPCD2V, both through-hole (V-Point) and dowel style, are another relative newcomer in the array of diamond tools offered. While they do not run the marathons that their hogger, saw blade and routing counterparts are known for, they still offer a stately price/performance ratio that should not be underestimated or overlooked.

To summarize, panel processors not using diamond tooling in their production, are overlooking a tremendous opportunity to improve their bottom line! Letting the initial cost of diamond tooling intimidate…is ignoring the fact that in most cases, PCD provides the lowest cost per linear foot machined!
