Precision CNC Boring Drill Chuck 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…read more

Tooling Basics for CNC Machining Below is an article GDP|GUHDO contributed to FDMCdigital.com January 2015 edition (formerly FDM/Cabinetmaker)    Understanding fundamentals of CNC tooling can make a huge difference in your costs, productivity, and efficiency.  Most CNC machining centers for wood, plastics and composite machining today are equipped with steep taper ISO/SK/BT style, or more frequently…read more

Precision CNC Tool Holder Options Standard HSK collet chucks are currently the most common in use in the woodworking industry. They are relatively inexpensive, and highly flexible due to the wide range of collet sizes that are available and easy to interchange.   While HSK style collet chucks are a good choice for most applications, the multiple…read more

The HSK 63 Tool Holder The HSK 63 high-speed tool holders are made for use on precision CNC routers and machining centers, as well as point-to-point machines with automatic tool changers.  The HSK tool holding system was developed in Germany as a set of standards and performance criteria for advanced machining where precision is imperative. HSK shank…read more

Looking for ETS Style Collets for Your CMS Machine? ETS Style collets for CMS routers are becoming more difficult to find and are very expensive to buy.  We have BT30 and BT35 tool holders for both machine brands that take standard ER collets….a much lower cost collet to replace. These tool holders come with a…read more

Clamping Systems Clamping Systems are a decisive link between a tool and the machine spindle. Tool life and attainable work piece quality, but also safety are significantly influenced by clamping systems. Ideally the clamping system should be: of low weight of low imbalance compliant with the norm made of high quality steel Clamping technology assumes…read more

Deep Mortise Insert Bit in Thermotec Heat-Shrink Tool Holder Tool and clamping accuracy is essential to minimize runout with all cutting tool applications, but in particular with very long cutting tools as shown below. The further you move from the clamping source, the more pronounced the runout becomes.  Shown here is a deep pocket insert…read more

Saw Blade Clamping Adapters for CNC Machines GUHDO offers several clamping systems for mounting saw blades for use on CNC routers. Option one is a one-piece, integrated flange for mounting large diameter saw blades up to 400 mm (16”). The clamping flange offers an HSK63F machine connection with a flange to accept 30 mm bore…read more

The Importance of Ball Bearing Collet Nuts on HSK/ISO Tool Holders The importance of a ball bearing in the collet nut cannot be understated.  Apart from the fact that it allows the user to run both CW and CCW tools in the same tool holder, it is the solution to eliminating tool slippage problems during…read more

Precision ThermoTec Heat Shrink Tool Holder The ThermoTec heat shrink chucks are precision balanced to 30,000RPM with a runout tolerance of .003mm (0.00012″) making them great for high torque/high speed machining. In heat shrink chucks,  collets and nuts are not used between the tool shank and tool holder creating a more evenly distributed clamping force…read more

Improve Clamping Accuracy with Heat Shrink Tool Holder The Heat Shrink Tool Holder offers some substantial benefits when compared to standard HSK-63F tool holders. A Heat Shrink chuck creates a more uniform, rigid connection between the CNC machine and the tool resulting in less vibration and a noticeably smoother cut. Since there is no collet…read more
