BIG Kaiser Angle Heads Combine Operations

      BIG Kaiser Angle Heads combine vertical, horizontal and angular operations on one machine, improving runout accuracy and lowering the potential for error created by multiple setups, according to a spokesperson.

      Angle heads are designed to increase productivity by changing the angle of the cutter without repositioning the workpiece. Universal type angle heads (AGU series) are offered for machining all angles from 0 to 90 degrees with only one set-up. Angles are adjusted and set at 1 degree increments with a positive locating system. Models for 40 taper machines offer up to 1/2" collet capacity and run at speeds up to 6,000 RPM. 50 taper models offer up to 3/4" collet capacity and run at speeds up to 4,000 RPM.

      90 degree (AG90 series) angle heads offer fixed 90 degree angle in a variety of tapers, lengths and collet capacities (.010" to .787"), using BIG Kaiser's Baby Chuck system. A twin angle head provides two cutter heads 180 degrees apart, fixed at 90 degrees. AG90 angle heads offer speeds from 3,000 to 8,000 RPM.

      In the AG90 series, HMC type angle heads offer the combination of power and large diameter tool capacity, using BIG Kaiser's Hi-Power Milling Chuck system. Available in CV and BT 50 taper models, the HMC type angle head has a maximum speed of 3,000 RPM and tool diameter of 11/4". This model is offered as high rigidity "S" type made with a steel housing and reinforced locating pin for applications that require heavier cutting loads.

      Build-up type angle heads can be fitted with a range of 35 taper adapters to cover many machining requirements. Adapters are available for end mills, shell mills, slitting saws, drills, and tapping attachments.

      BIG Kaiser angle heads are equipped with hardened and ground chrome-nickel steel spiral bevel gears, precision hardened and ground spindles, and precision angular contact ball bearings.

      A compact design helps assure rigidity and minimize overhang, shortening projection length and reducing overall load. Minimized overhang also helps eliminate interference with the automatic tool changer (ATC) and connecting storage pockets in the tool magazine.

      BIG Kaiser angle heads use a non-contact sealing method designed to prevent coolant and particle contamination. A coolant jacket allows coolant coming through the stop block to be directed to the tool cutting edge while simultaneously cooling the angle head.

      Simultaneous dual contact between the machine spindle face and the tool holder flange face and the machine spindle taper and tool holder taper shank is also available, using the BIG PLUS Spindle System. According to the company, simultaneous spindle and flange contact helps enhance rigidity and repeatability, which yields many benefits in higher metal removal rates, higher accuracy, improved surface finish, and extended tool life.
