Milling machine for machining the back of steel keys

Used milling machine completely overhauled.

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 form 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
