The production of very small parts, in particular for watch movements, requires turning tools designed specifically for this type of machining. In 2012, Applitec launched a number of inserts dedicated to the watchmaking field, and demand has increased considerably since then. To such an extent, in fact, that Applitec is now launching a new complete range of turning tools for machining watch parts.
Watchmaking bar turners have increasingly requested specific dimensions and angles which have substantially exceeded those covered by the original offering. Technical manager Pascal Kohler explains: “With brazed hard metal tools, each bar turner would sharpen his or her tools as habit or requirements dictated, whereas nowadays they all request the same operations on our reversible inserts.” And although the company still offers special customised solutions, it has undergone significant rationalisation and now offers a wide range to cater for all needs.
A top range
The new range of dedicated watchmaking products is called Top-Watch, and draws on the strengths of the Top-Line range (reversible ground inserts) well known to users, notably the positioning and clamping system of the offset tooth inserts, which offers unparalleled rigidity compared to traditional clamping systems.
Really sharp edges
There are various treatments involving ultra-fine layers to prevent cutting edges from being rounded, but are they always enough? According to Mr. Kohler: “For extreme cases, we offer an insert with a coated blank, on which the tapers are sharpened after coating.” He adds: “The coating on the cutting surface prevents sticking, and the lack of a coating on the taper is not a problem. That means we can offer an ultra-sharp cutting edge.”
There are many more features to discover in the new watchmaking range. It is available in stock and will be on show at Siams in Moutier, on the Applitec stand, C15, Hall 1.2.
