Used machines:
Milling machine for machining the back of steel keys

consisting of:

• Robust machine frame with precision-milled base plate.
• Loading magazine for fitting bar magazines.
• Automatic loading unit
• Pneumatic loading pusher with quickly interchangeable masks for the respective key type.
• Ejector or hold-down lever similar to the FIMAT machine you are currently using. Chute for transferring the milled keys into a bin.
• The entire loading magazine can be moved axially on precision guides by +/- 20 mm. An adjusting spindle with position indicator is provided as a setting aid.
• The entire magazine block is secured by means of a clamping bar.
• Pneumatic power clamping device for holding the two key-specific clamping jaws.
• These jaws can be changed quickly when switching profiles. Clamping device adjustable by +-1° via set screws.
  With precisely manufactured jaws, adjustment should only be necessary once!
• Precision clamping jaws (wire EDM). An extension to additional keys is possible at any time.
• 2-axis NCI milling unit with ball screws and linear slide guides
• 1 milling spindle with three-phase motor for machining the back. The SK30 milling arbor for holding the corrugated milling cutter is replaceable (mechanical quick-change with drawbar).
  This means that cutters with different bore diameters or lengths can also be used if required.
• Motor with belt drive in Z arrangement
• Power: 1.5 kW
• Speed: 3000 rpm
• Frequency inverter for infinitely variable speed adjustment
• Chip deflectors and a chip drawer integrated into the machine table.

Optional chip extractor available on request; however, from today’s perspective this should not be necessary.

Automatic loading unit with additional refill hopper.
consisting of:

• Welded bracket with boring-mill machining for mounting the components
• Refill hopper (heavy-duty version with 40 kg payload)
• Vibratory bowl feeder with discharge baffle, diameter 400 mm
• Inductive level monitoring
• Pneumatic singulation
• Turning wheel 1 (inductive detection of head position)
• Turning funnel (tip detection via laser photoelectric sensor)
• Transfer rail to the stack magazine
• Control units
• Control system expansion

• BECKHOFF control system with touch panel. Recipes for the various key types and back variants can be stored.
• 2 Beckhoff servo axes AM8023, 400 V AC, Mo= 1.20 Nm, multiturn absolute encoder, Z axis with brake.
• Beckhoff built-in panel PC with 6.5" touch interface, control cabinet with all required control components, fully wired and tested; the visualization is created with TwinCat HMI.
• Recipe for saving various motion profiles.
• Creation of the circuit diagrams in Eplan8.
• The control cabinet is permanently mounted to the machine frame.
• The operating elements and the panel PC are mounted in the side wall of the control cabinet.
• Machine installation and initial commissioning at AUMAT.
• ITEM safety enclosure
• Staff training during acceptance at AUMAT.
• 3 sets of jaws and 3 magazine pushers are supplied, corresponding to the sampled keys.

Cycle time: approx. 3 seconds/keyChange parts for milling machine for machining the back of steel keys
consisting of:

• 5 sets of clamping jaws, precision wire-EDM, hardened to HRC 60

• 4 key pushers, contour-EDM, hardened and ground

• Staff training
