325linear from Schutte extends high precision grinding
The 325linear from Schutte extends the tried-and-tested, high-precision 5-axis CNC grinding machine series 305: its extended axis paths, increased rigidity and 2 auxiliary slides for workpiece clamping and guidance cover your machining tasks from microtools to gun drills. For production parts such as implants, the enhanced axis dynamics result in improved surface quality and reduced cycle times. The use of linear direct drives, optimised guidance and cooling systems further increases the proven high positioning and track accuracy.
The extremely compact and well-arranged design of the 325linear offers an even more rigid structure so that the extended X and Z paths can be traversed with maximum dynamics in the shortest possible cycle times. Workpieces ranging from extremely small drill bits through production components up to hob cutters are guided and positioned precisely. Wheel change and handling systems round off the productivity of the 325linear.
The innovative second auxiliary slide permits the combined use of tool guidance, support, tailstock or workpiece pallets. Thanks to the modular structure, the equipment can be set up flexibly for a very wide variety of workpieces and process tasks on both of the slides as an option.
The SIGSpro software provides consistent support for users: At the machine or a PC workstation, you can program the machining operations and devices with operation and menu guidance. The 3D simulation also allows you to prepare the most complex clamping situations offline, to check for collisions and to optimise cycle times
