titled 'HMCs Built for Rigidity'
AV-Tech Machine Tool has added the HT-500A and HF-380 series CNC HMCs to the Twinhorn line. The machines are designed with high-tensile Meehanite cast iron on all major parts to increase rigidity. They also feature a three-layer, T-shape, box-type design. The base structure’s multiple layers and enforced ribs prevent deformation and reduce vibration during high-speed operation, the company says.
To further enhance stability and resistance of column motion, the machines feature a differential slide base and high-/low-level X-axis guideways with a 580-mm-wide span.
Other features include external spindle cooling systems, air-lock systems on spindle noses and floating-tool clamp/unclamp systems to reduce noise and vibration
