Spindle HeadThe spindle is mounted directly to the Fanuc spindle motor for faster acceleration anddeceleration, and to reduce vibration during high speed operation. The powerful 18.5kW(24.8Hp) spindle motor drives the 40 taper tools at speeds up to 10000 r/min.

The refrigerated spindle cooling systemcirculates cooling oil to maintain aconstant temperature for high accuracy,regardless of the ambient temperatureor cutting conditions.

The dual contact systemoffers simultaneous dualcontact between the machinespindle face and tool holderflange face.

Suitable for high productivity.

The automatic 180 degree indexing pallet table is an integral part of the VC 430 / VC 510. The table mechanism is mounted directly to the bed of the machine on a horizontal plane toenhance the table rigidity. Because the table is stationary during machining, the non-cutting sideof the indexing table can be set-up while the workpiece is being machined on the machine side.As an added feature, rotary table cables and work holding hoses can be run down from the sheetmetal wall.

High RigidityStable bed and column assemblies are designed for high speed and heavy duty machining.

Rigid Body Interface for Additional Equipment

Rapid Traverse

The one piece bed is a rigid, heavily ribbed, Meehanite casting that remains stableunder the heaviest cutting conditions. Fine grained Meehanite cast iron is used forits excellent vibration absorbing characteristics. The VC 430 / VC 510 features asuperior traveling column design. The table, and therefore the workpieces, remainsstationary during machining. This design provides a uniform load to the guideways,ball screws and motors.

Advanced Performance & Units

The large-scale cutting oil pump and tank arelocated away from the machine's main body toprevent heat transfer. The pump generates 60 HZpower when measured at the pump outlet. Themain axis cutting oil device (T-S-C) is available asan option.

Through Spindle Coolant

Flood Coolant

The large capacity coolant tank is located onrollers. The coolant tank is isolated from themachine bed to prevent heat transfer andassociated thermal distortion. Providing highvolume flood coolant as a standard feature.

Coolant System

std.

opt.

A standard rigid tapping functionallows synchronized, high-speedtapping with a standard colletchuck. This eliminates the need for special tap holders.The tapping depthcan be accuratelycontrolled.

Rigid Tapping

A lubrication system providesautomatic lubrication to allguideways and ball screws.The way oil is delivered bypiston distributors whichprecisely meter the volume. Alow level alarm prevents themachine from restarting.

Coolant tank

Coolant chiller

Coolant Chiller

The coolant chiller lowers coolant temperature,helping to cool both the workpiece and toolduring the machining operation. When usinginsoluble cutting oils, a coolant chiller isrecommended to cool heated oil and preserve machining precision.
