Quick-Change Pallet System Features High Retention Force Spindle Choices Enable 5-Axis HMCs to Machine Variety of Materials Designed for both powerful and high-performance machining, HBZ Trunnion five-axis horizontal machining centers from Handtmann offer a variety of spindle types suitable for machining aluminum as well as steel. The series includes the HBZ TR 80 with turning option, which features an 800-mm table; the HBZ TR 120 with a 1,200-mm table; and the HBZ TR 160 with a 1,600-mm table size. For machining aluminum, the machines use a 125-kW spindle that can achieve speeds as fast as 30,000 rpm for a high chip removal rate and reduced machining time. A horizontal machining configuration and large chip conveyor support the high volume of chips produced. Rigid tool interfaces allow the use of spindles with high torque for machining materials like steel. They can be machined on the compact HBZ TR 80 at as much as 430 Nm torque, while the larger HBZ TR 120 and HBZ TR 160 offer maximum torque of 1,010 Nm. According to Handtmann, it is primarily the rigid machine design that enables the use of the different spindles. Essential components were constructed to achieve maximum rigidity at a high table load and under dynamic conditions. For example, the Z axis uses a welded steel construction because of the higher E module; the A axis is driven and clamped from both sides; and the X axis is driven and fitted with upper and lower guideways. These factors, along with the use of three-point floor mounting, resist the particularly high feed forces. The Handtmann Spindle Monitoring System (HSMS) is designed to monitor and optimize all processes, continuously checking vibration, bearing temperature, rotation speed, etc. The HSMS also can automatically define optimal feed values and rotation speeds. The HMCs can accommodate both Siemens 840D SL and Heidenhain TNC640 controls, and offer a flexible tool range, including large tools for applications with deep cavities as large as 400 mm on the HBZ TR 80 and as large as 500 mm on the HBZ TR 120 and 160. The tools are held in magazines with various tool capacities.

This high retention force increases the clamping system's rigidity, enabling considerably higher cutting forces; even extremely high shear forces can be absorbed reliably, the company says. The Vero-S is designed for increased precision, efficiency and process reliability with reduced setup in metal cutting and CMM inspection. The Vero-S uses one or more clamping pins to clamp workpieces, pallets, clamping stations, existing fixtures and tombstones. Its radial-aligned clamping slide pulls in the clamping pin and locks it. Exact positioning is accomplished via a short taper. Radial location is done via a diamond pin, ensuring a repeat accuracy of at least 5 microns (0.0002"). Holding forces of as much as 16,800 lbs can be achieved. A pneumatic pressure of 6 bars (85 psi) is sufficient for opening the module. The system is completely compatible and interchangeable with Schunk's previous pallet systems, and the clamping pins work universally across the line. Workpieces can be transferred from machine to machine or to a CMM accurately and seamlessly, the company says. The module is completely sealed and protected against the penetration of chips, dust and coolant. An air purge connection is integrated into the standard module and can also be used for part recognition. The position of the clamping side can also be monitored via an air purge monitoring system. The module also is equipped with bottom and lateral air connectors for mounting flexibility. For more information from Schunk Inc. of Morrisville, NC, phone 919-572-2705 or visit us.schunk.com.
