Helping your customer with the right technical recommendation is always the best way to secure a long lasting collaboration. In this case, let’s start from checking the hole size before tapping, definitely one of the critical steps to ensure reliable screw threads. With Yamawa Check-pin box, you can master this part of the job for… Read more »
This article deals with the most important factors to consider when using taps with internal coolant holes: the filtration system and coolant discharge pressure that need to be carefully configured to achieve the best performances of the process. Keep an eye on the filtration system When using a tap with coolant holes, Yamawa recommends to… Read more »
Mold & die industry often deals with ultra-hard materials that require specific taps to face the resistance of steels to be cut. UH-CT carbide hand taps are designed for tapping hardened steel and extremely high hardness steel up to 60 HRC. This article gives some practical advice for getting the most from these tools. Bored… Read more »
When tapping with a tension/compression holder on a machining center, sometimes the hole does not accept the No-Go gauge (oversize internal threads). However, any chipping and welding on the tap is visible. This problem usually occurs because of an over- or under-feeding. The observation of the rake surface on the tap’s flutes gives an idea… Read more »
When tapping different materials using spiral fluted taps, some issues such as the chipping of the tap, tap breakage, tap welding may take place occasionally. The adoption of some precautions helps overcoming these problems. Selecting a different diameter of the bored hole is a simple and feasible trick. Making the bored hole as large as… Read more »
The oxidation treatment (i.e., OX treatment) creates porosities or small pockets on the surface of the tool. Drops and molecules of the cutting fluid accumulate in these pockets and help with the lubrication of the tool. The enhanced lubrication reduces the friction between the tool and the workpiece and helps to prevent chip welding. The… Read more »
