A common machining – and safety – problem in high-speed applications is the pull-out effect the high forces create on the end mill. These extreme forces seem to engage in a tug-of-war with the end mill, trying to extract it from the toolholder. A loose tool could spell disaster for the application as well as the machine operator.
The new Safe-Lock by Haimer pull-out protection system guards against unexpected end mill pull-out from the holder. It’s designed especially for heavy-duty machining, where pull-out risk is high.
The Safe-Lock system features a series of spiral grooves ground into the cutting tool shank. Combine these grooves with the pin drivers in a shrink fit toolholders and the result is a secure holding system that keeps the end mill in place. Think of it as a seatbelt for the cutting tool.
When heavy-duty machining materials like titanium, Inconel, and aluminum, the pull-out risk is eliminated while the safety factor is greatly increased. Better productivity, less scrap, and less vibration all combine to your benefit with Safe-Lock.
Traditional clamping methods were the shrink fit and Weldon systems, but both had drawbacks. The Safe-Lock pull-out prevention system combines the best features of these traditional methods, including a frictional shrink fit and interlocking connection of toolholder and cutting tool. This results in excellent run-out and no tool pull-out risk.
