TWO-AXIS MILLING HEADS TCH SERIES TECHNAI Two-Axis Milling Heads with Electro-spindle Recommended for new generation milling machines with horizontal or vertical axis, intended to take advantages by 5 axis machining strategies: full 5 axis and/or 3+2 axis machining process techniques are made possible by the integration of the TCH milling heads. The TCH series is expressly designed for following machining fields: Mould & Die, Injection mold, Aerospace parts and general Mechanics. HEAD STRUCTURE TCH MODULAR CONCEPT DESIGN All the TCH Head are designed with an innovative concept of “open...

TCH 13 H is compact like the heads with single arm but with the advantage of the greater rigidity of the fork structure which allows to support the spindle on both sides. Excellent price-performance-precision ratio, it is suitable for receiving Electro-spindles with body up to D180mm. The TCH 15 is the small-medium size head with a perfectly symmetrical fork structure, it is suitable for receiving Electro-spindles with body up to D190mm. TCH 15 expresses a new up-grade of excellence of Technai’s Direct Drive technology and is intended for applications that require maximum precision and...

TWO-AXIS MILLING HEADS TCH SERIES TCH 13 H is the most compact two-axis head with a fork structure offered by Technai Optimal price-performance-precision ratio, accepts electric spindles with a body of up to D 180mm with a torque range of 35 -: - 60 Nm. Designed to excel in mould finishing, it is distinguished by optimal thermal stability. It is best used when equipped with high quality electric spindles It has Direct Drive motors on both axes that allow for optimal fluidity and excellent precision in executing the finishing trajectories with controlled axes (full 5-axis mode) It has...

TWO-AXIS MILLING HEADS TCH SERIES TCH 15 is the medium-small sized two-axis head with technical contents that reflect the state of the art and the experience of Technai in the design of Direct Drive heads. The structure is fork-shaped with a double motor on the A axis - perfectly symmetrical - and it adapts with a few variations to be configured when processing moulds or aluminium and composite components of aeronautical structures: • To process moulds with an extended spindle body and an electric spindle of selected quality • For "aerospace" processing in the most compact configuration and...

ELECTROSPINDLE TYPE

TWO-AXIS MILLING HEADS TCH SERIES Two axis head with fork structure, optimized for 5-axis machines, integrates modules with Technai Direct Drive motors on both axis, and is available with electrospindles up to 24.000 rpm and 50 kW, HSK-A63 or HSK-A100 tool holder. TCH 20 head is designed to equip big 5-axis machines and it is characterized by a compact structure which integrates the C-axis Direct Drive motor in the fork structure. The short distance between the spindle nose and the A-axis makes the TCH 20 suitable for a wide range of machining application: • aluminum structural parts for...

TWO-AXIS MILLING HEADS TCH SERIESThe new TCH 30 is the "Large" size of the Technai range, it allows the integration of an electrospindle with body diameter up to 315mm and torque in the range between 250 and 300 Nm. The new TCH-30 renews the former TCH 30, and integrates the latest features homogeneous to the entire line of Technai heads, in particular: . Integration of a wider choice of electrospindles. • Improved geometric accuracy and qualitative positioning accuracy. • Simple and intuitive adjustment of the geometry of the two rotary axes. • New absolute encoders on both axes. •...

TWO-AXIS MILLING HEADS TCH SERIES TCH-U 40-50 head declines the concept of universal head for undercut milling operation in the full direct drive version. The goal is achieved by integrating the torque motors of the C and B rotary axes with a powerful electrospindle for the tool actuation. The product is mainly intended for the general mechanical industry and is optimized for milling machines or machining centers with vertical ram (bridge type or gantry machines). TCH-U 40-50 is equipped with 47 kW, 1 50 Nm and 1 3.000 rpm electrospindle, that is a well-balanced set of performance for...

DIRECT DRIVE TECHNOLOGY The Direct Drive principle is simple: The electric servomotor generates mechanical power needed to move the final load, driven by the electronic-digital servo-control. At the beginning machines were servo-controlled by drives CNCs and PLCs to which was assigned the limited function of automatically generate the sequence of movements previously performed “by hand” by the operator; precision and quality remained a characteristic of the mechanical quality of the machine. The second generation of electronics control introduced assistance and compensation functions to...

A Direct Drive system with Torque motor releases the potential of electronic regulation achieving immediate benefit. The absence of gearbox means that most of problems associated with friction, wear and other cyclical drive defects, are overcome. Performance can be configured according to the technical specifications, up to the limits of individual components that from the Direct Drive system. Also, the number of components and assembly costs are reduced. The simplified, symmetrical structure facilitates the construction of adjacent parts. The combined result of such aspects leads to a...
