Angular concrete workpiece milling machine - has conveyor belts arranged in oblique Z=section to form workpiece supports

摘要

The machine mills and/or grinds the surfaces of angle-section concrete workpieces. It has supports for the latter at right angles, forming an angle open to the top to allow milling of the inside surfaces. Belts (17,19) form the supports and conveyor. For milling the outer workpiece surfaces, further conveyor belts (18) are provided, in planes at right angles to the adjacent ones and forming an angle open to the bottom. Thus the belts together form an oblique Z-section. The belts can be driven by two shafts (20,24) at right angles and parallel to the two planes formed by the Z and coupled together. Each shaft drives only the belts parallel to it.
