GDP|GUHDO Tooling for Flip-Flops?

This is one of our customers running a test to cut something a little unusual… GUHDO tooling is great for cutting everything from composites to foam as we can see from the video.

 

 

Proper Use of Drill Bits on CNC Machining Centers

DSC_0019Using solid carbide drill bits in a standard collet on a CNC router often leads to vibrations causing a poor finish and tool breakage which can get expensive if you are drilling hard wood or composite materials (as a note – PCD diamond tipped drill bits are recommended for composites). When compared to spiral router bits, drill bits are run at a slower RPM generally and while breakage might be tolerated if you only drilling the occasional hole, it can become a problem with production runs of greater volume.  The reasons for this problem are two-fold:

DSC_0009

1)      Your using a 10mm shank bit (w/flat on shank):   Most metric drill bits have a 10mm shank with a flat area machined onto the shank (for set screw tightening).  When inserted into a 10mm collet this flat spot prevents the collet from concentrically gripping the shank all around. (see image).

The solution: a small drill adapter (6381) that goes between the collet and the drill bit fills this space and allows the collet to concentrically grip the shank.  This adapter has a 10mm cylindrical shank (no flat) to go, which accepts the 10mm shank w/flat drill bit, tightened with a set screw as is standard on boring machines.

2)      Using cylindrical shank bits (no flat on shank): Many in-between or uncommon sizes of cylindrical shank drill bits don’t fit snugly into the closest collet size available and therefore slip or chatter during the drilling process.

6380

The solution:  a Universal drill adapter (6380) which comes in two diameter ranges, infinitely adjustable within the specified range.  (accepts 1-13mm diameter drills, or 3-16mm diameter) and is available in HSK63 F, ISO/SK30 and SK40 version.  The 6380 Universal Drill Adapter has high-clamping power and accuracy, is Made in Germany, and can be run either clockwise or counter-clockwise.
