Cylindrical grinding machine - Import export

To achieve the required shape and dimensional accuracy, Tyrolit offers vitrified-bonded, resin-bonded, and electroplated CBN and diamond wheels. Our abrasives ensure safe working without thermal damage to the workpiece. This process is typically used for cylindrical or tapered workpieces, especially joints with an axis or shaft, such as gears, steering systems, injection systems, and hollow shafts. Tyrolit provides vitrified-bonded tools with excellent profile retention and cool finishes, reducing thermal load. Depending on the material, we recommend our superabrasives over conventional tools. Our resinoid bond, specially developed by Tyrolit, ensures shorter grinding times and maximum process stability. Resin-bonded diamond and CBN tools offer long tool lives and high dimensional accuracy. Electroplated tools exert low grinding pressure, ideal for small diameters.

External cylindrical grinding is essential for achieving optimum surface finishes on workpieces like camshafts, crankshafts, and transmission shafts. It's used on various materials, including unalloyed, low-alloyed, and high-alloyed steels, HSS, tungsten carbide, industrial ceramics, and cast metals. The key to selecting the right tool lies in matching the grinding wheel to the specific requirements of the grinding application. This involves considering workpiece properties, tool, machine, settings, cooling lubricant, and dressing technology. Our high-quality tools and consulting services ensure optimal process parameters. Tyrolit offers a wide range of high-quality grinding tools for various applications and materials. We provide vitrified-bonded conventional wheels with different grains for specific materials, and resin-bonded high-performance tools made of CBN or diamond with our special bond system. The VIB STAR system reduces vibration for a smooth grinding process.

The mono-base design of the multiLine models allows grinding widths (Z-axis) of up to 900 mm. The compact, steel base designed multiLine model is equipped with linear guides in all three axes. The feed axes Y and Z are driven via servo motors and ball screws. For machines up to 2,000 mm the table is driven via ball screw (KGT). For longer tables up to 6,000 mm a linear motor (LIM) is used. The standard version of the multiLine comes with high-precision linear scales for positioning of the vertical axis. The direct drive grinding spindle with up to 37 kW guarantees optimal torque transfer. To meet your requirements this model can easily be customized through a large variety of available options like different types of overhead and table mounted dressing units for using Al-oxide or CBN/diamond grinding wheels.

Our gantryLine models can process large, wide and heavy workpieces up to lengths of 5000 mm and widths up to 2000 mm with high precision. Special designs are also available to process wider and longer workpieces. This machine line with its variety of available features is suitable for surface grinding applications all the way through complex CNC manufacturing cells. Next to the horizontal grinding spindle a vertical tiltspindle can be mounted for grinding for example machines beds with under grip. The sturdy gantry-style machine design features a modern vibration-free mechanical table drive, linear guideways in all axes, an over-sized spindle drive as well as ball screws and linear scales in vertical and cross axes. These features guarantee that today’s expectations in the precision machining of large surfaces are met for rough machining and high precision machining as well. The gantryLine achieves highest workpiece precision and surface quality.

The millGrind series is specially developed for the requirements of machining in the turbine industry as multiple technology solution in one set-up. The modular machine system in travelling table design allows an individual configuration of the machine according to the customers' needs. Automatic tool and diamond roll changing allows the machining to machine with — Al-oxide, CBN and diamond grinding wheels — Drills — Milling cutter — Laser cladding — Measuring of the unfinished workpiece — Measuring of the machine workpiece including rework in one set-up. This guarantees that all machined surfaces run to each other and errors are avoided by repeated re-chucking. In addition to the machining of new blades and vanes for rework a laser cladding device can be added. This allows the measuring, cladding and grinding or milling of the worn areas.

This model is well suited for efficient, economical processing of circular workpieces via surface and step grinding operations. There is no lost time through deceleration, acceleration and reversal as with conventional reciprocation grinding. The grinding wheel remains in contact with the workpiece throughout the grinding process. Single workpieces can be located centrically on the table while multiple workpieces can be located concetrically to optimize table space utilization. A tilting table option allows grinding of chamfers or blade edges (i.e. circular blades), where the table can be tilted +/- 5 degrees. The high-precision rotary table is belt driven. This machine is offered with the xpressCube SPS controls package. A software option is available for step grinding operations. Benefit Overview — Compact and robust machine design — High productivity through continuous contact between wheel and workpiece — High long-term precision — Precision rotary table — Easy to operate
