secutex – the gentle power against raw impact forces. If screwing or welding is not possible, just glue the secutex where impact protection is required. No problem with the secutex special bonding material. These are the advantages by gluing (nearly) everywhere applicable No drilling or welding necessary Bonding where welding or screwing is impossible Applications Thin to medium thick wood plates Glass and plexiglass Sound absorbing elements Fine wood surfaces Examples Coolhouses Painted, laminated, veneered walls and surfaces According to special requirements A proper bond requires always a good preparation … The following procedure is needed 1. Cleaning of the surface Suitable grease and siliconedissolving cleaning agents are required. This step is important to ensure that there is no dirt on the surface which may be present during the grinding or sandblasting process. 2. Roughening the surface Sandblasting or grinding of the surface are especially suitable here.

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 ecoLine linear model surface and profile grinding machines are comprised of a single steel base design. The longitudinal linear motor drive table with a max. speed of 60 m/min is its defining characteristic. Since 1999 hundreds of these travelling table machines have been delivered and are well established in the market. The ecoLine model is available with a grinding area of 1,000 / 1,500 / 2,000 x 700 mm. The machine is equipped with linear guides in all three axes. The Y- and Z-axes are driven by servo motors and ball screws (KGT) while the longitudinal X-axis table is powered via direct drive linear motor. The standard 11 kW grinding spindle can be upgraded up to 26 kW. A wide variety of available options like different types of dressing units provide customization capabilities for specific requirements.

The smartLine covers the entire spectrum of travelling table grinding machines. From simple reciprocation surface grinding through speed-stroke, slot and profile grinding all the way to creep-feed grinding. This machine concept solves every grinding task. The machine‘s versatile building block system is designed to allow almost any combination in table drive systems from belt drive to ball screw system in combination with table mounted and overhead dressing units to solve your specific grinding task. The Kombi-version of the smartLine allows individual configurations all the way up to a complex creep-feed grinding machine. Grinding width, grinding height, type of drive and spindle power as well as all variations of dressing units from simple table-mounted dressing diamond to CD-grinding with a headmounted roll dressing unit as well as an automatic tool changer for grinding wheels and dressing tools can be selected to meet specific requirements.

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
