 Roberts Sinto BarinderCompetitor
HistoryProven technology Developed in 1972 with over 35 years of proven historyNew product developed in 2003. Very little history
Unit Sizes3 Standard Series with a variety of in each series2 Unit sizes available
Foot Print6’ x 8’ x 8’ H (saving valuable floor space)7’ x 10’ x 8’ H (utilizing valuable floor space)
Design(4) Servo axes positioning arm, single axis servo grinding head with servo index table (gives you multi axes part positioning with less components)6 Axes robot with 2-position indexing table (complex part positioning with more components)
ConstructionNo conventional robotic wrist required with servo drive motors at each point of motion (eliminates any damage that may be caused by grinding vibration on conventional robotic wrists)Conventional robotic wrist and typical torque tube servo drive system (vulnerable to damage that may be caused by grinding vibration on conventional robotic wrists)
Part Positioning360º or greater continuous servo rotation of casting during grinding (positioning arm has unlimited “A” axis rotation for continuous part to wheel contact during grinding)4-position pneumatic indexing fixture plate on 2-position pneumatic turntable (grinding wheel loses contact with casting during repositioning)
Turntable Features
Grinding operations are isolated from part loading/unloading (offers undisturbed grinding)
Castings are loaded/unloaded during grinding operations on turntable
Turntable Options2, 3 or 4 Station servo positions (each station can handle a different part arrangement)2 Station pneumatic
Part ClampingSingle casting clamping device on positioning arm (utilizing less components)2 Clamping assemblies (1 at each station on turntable doubling components)
Fixture Program ConformationEmbedded chip confirms program to fixture to eliminate crash potential (Provides the ability to change programs on the fly)Hand Scanner Optional
Main Wheel LifeAbility to run large diameter wheels reducing heat buildup (customers have documented 5 – 6 months of production between wheel changes)Smaller diameter wheels generating heat buildup (heat will damage diamond wheels causing shorter wheel life)
Available Spindles1 Main tool & 1 aux. tool standard (aux. tool can handle multi shaped tools; 6 sec. for one tool change)Offers 1 as standard Optional quick change (20 sec. added to cycle time for each tool changing)
Program Storage99 in unit
Unlimited via Ethernet package
Disk storage via FANUC Handi File
Limited to size of processor
Program Training1 Day or less at your facility(no experience needed)1 Week of Robot school (robotic knowledge required)
ProgrammingTrace, teach & adjust inside unit standard (2 - 4 hours per casting)Robot programming standard Off-line software optional (1 - 2 hrs. in office + 2 - 4 hrs. inside unit per casting)
Path ControlAmperage monitoring on spindle automatically reduces positioning arm speed for max. grind performanceMonitors amperage on spindle to signal change in wheel RPM speed to peak level
Processor ConfigurationSingle processorMultiple processors with cell PLC and robot controller
