Ayma tools shows on its stand, Pavilion 4, booth B39-C40, the new TTS system of transmission of of Mapal-Ayma, a connection of an ideal tool for the transmission of high pairs. Addition, the signature takes the pageant to show reamer the new bit expandable HPR to obtain maximum precision reamers multi holes edges.

TTS system of transmission of of Mapal-Ayma

Now that the system HFS is fully trusted and established as a connection of high precision fine machining; Mapal-Ayma introduces a new connection tool, specially designed for the transmission of high pairs.

The TTS system (Torque transfer system) allows you to reduce the use of hard metal with interchangeable heads and achieve both high quality and excellent results in machining.

The connection is characterized by a radial teeth of 12 to 18 teeth. The teeth innovative geometry ensures an optimal transmission of torque and high precision in the change of the tool and the concentricidad.

TTS for drilling, milling and slotted

With the connection of precision TTS system (Torque transfer system) have emerged new fields of application, both for drilling, milling and slotted; as well as for the combination of tools.

In the area of solid drilling, the TTS connection is available in the standard program. The transmission of torque with interchangeable head drill bit is available for a wide range of materials from Ø16 Ø32 and length of drilling 3xD and 5xD. In the transmission of torque drill the teeth of connection is subject to safety through a strained and a pin Threading on the side of the tool. The supply of coolant to the interchangeable heads is assured by a safety device incorporated in the teeth. The tools of milling and slotted are tied by a strained well by the front or well behind the tool.

Example of application: increases the useful life of the tool in milling by contouring of guides.

An example of the success of the tools with the transmission system, is the tool for milling by contouring in grinding of steel (C60) guides. The head of milling of 5 edges of hard metal (Ø28mm) is subject to the tool with a cylindrical shank with connection TTS and machined the delicate profile with a preview of Vf = 950 mm/min and a depth of ap = 1, 8 mm. Strong vibration, both from the piece and the machining, require a high stability and rigidity in the connection of the tool. To compare the BUR of interchangeable head of Mapal-Ayma with TTS connection with a tool of interchangeable head of competition, Mapal-Ayma tool increased useful life in 30% to 1100 pieces.

New expandable reamer bit HPR

There are completely new opportunities to the development of the adjustable HPR reamers of interchangeable head. The edges can be adjusted with great precision. This means that holes can be machined with total reliability with tolerance in the field of IT6. In addition, with this system of regulation, the wear of the phyla considerably increasing the useful life of the tool can be compensated. This provides a significant reduction in machining costs.
