The mounting and setup is performed easily and quickly. The support inserts are held by a quick clamping system and can be aligned to the taper angle. High Frequency Spindle The high frequency spindle is used for the grinding of pockets of inserts and for grinding with small diameter wheels. The HF spindle can be mounted in the place of a standard spindle. The spindle turret can even host several HF spindles. Machine Control The Model Evolution is configured with the CNC control Num. This allows for customisation of your grinding strategies, as well as compatibility with your existing Programmers and/or Operators Know-How. The CNC control has its own unique drive technology and programming System. NUM Software NUMROTOplus® with 3D Simulation and Collision Detection Profitability through high automation The machine can be equipped with an automatic tool loading unit, allowing 24/7 and un-manned operation. Yüksek Kapasiteli Takım Yükleme Ünitesi / Tool Loading Unit with High Capacity The tool loading unit consists of 2 accurate CNC-Axes (X2 & Y2), as well as pneumatic motion and clamping units. The tool loading unit consists of dual pallets and dual grippers. During a single loading sequence, a new blank is taken from the 1st pallet by gripper #1 and awaits completion of the grinding cycle. Once grinding has completed, the tool loading unit enters the machine, removes the finished tool with gripper #2, inserts the new blank into the collet and exits the machine. The finished tool is then placed into pallet #2. The TTB standard pallets (tool diameters from 1 to 16 mm) can contain upwards to 814 tools, which depends on the tool diameter. Customerspecific solutions, such as special pallets or loading sequences can be provided upon request. Flexibility by a multitude of accessories TTB can supply special peripheral equipment, accessories and special units upon request • Coolant filter and supply pump units • Tanks and transfer pumps • Chillers • Oil mist filtration systems • Fire protection systems • Optical measuring systems for grinding wheels • Image processing for tool positioning • Special measuring systems with laser or probe technology • Assembly units for specific applications • Special loading units Kinematics The Evolution consists of 2 groups of axes, the grinding unit and the workhead unit. They are mounted onto a cast iron base plate. The base plate is supported by special anti-vibration pads, to avoid interferences from external sources. The grinding unit (A & Y-axis) controls movement of the grinding wheels. The workhead unit (U, V, X and Z- axis) controls movement of the tool. The U-axis has dual functionality: it can be used as a positioning axis or a freeturning spindle (used when cylindrical grinding). The TTB kinematic allows the wheels to grind above or below the tool. The thermal stability of the machine components is guaranteed by the use of temperature controlled fluids. The heart of the machine is the spindle turret, consisting of 4 spindles. Each spindle can be equipped with up to 3 different grinding wheels. This feature provides the machine with important advantages: • All required grinding wheels are always and instantly ready for use in the machine. • The selection of the grinding wheel is performed in seconds. • Absolute accuracy in positioning and repeatability. The tools can be ground in one clamping and with the highest degree of precision. Additionally, the linear axes have a “one of a kind” motion-driving system; a combination of hydrodynamic technology and a calibrated preload. The conclusion: guaranteed unparalleled repeat accuracy and backlash-free movements of less than 0.0004 mm. Setup of the Machine For setup of the Evolution, there are choices of various workpiece spindles, clamping systems, wheel spindles and wheel flanges. This allows individual configurations and optimization of the machine for a specific grinding task. Changing of the modular units happens easily and quickly. The tool measuring probe is standard equipment for the machine. The grinding wheels can be trued and measured while mounted inside the machine.
