Tong-Tai (Topper) introduces a 20" pallet horizontal machining center -- the HB500. This is the first of a series of horizontal machining centers the designs of which are based on proven
concepts by well-established Japanese manufacturers. This design makes the machine suitable for general-purpose applications or high speed machining applications. The X & Y movement
is on the column with the Z movement being on the table. This combination allows for sufficient area for chip removal in high speed machining applications.
The machine base is a 20" x 20" pallet with an automatic pallet changer. The maximum part dimension is 36" x 36" with a total maximum weight of 1,300 lbs. The standard indexing on the
pallet is 1 degree. There is an optional 4th axis available. It has a 50 taper (HSK optional) built-in spindle with 30HP main motor and a maximum rpm of 10,000. External spindle cooling
and coolant through the spindle is standard on the HB500. For high speed machining and high material removal applications, there is also a coolant wash inside the bed, coolant wash from
the ceiling, an 8 piece coolant nozzle in front of the spindle and a fully enclosed splash cover to contain all the fluids and chips.
Strokes of the axis are X 32", Y 28", Z28" with a rapid 1990 ipm traverse. The machine has a Fanuc-18iM control with rigid tapping and capabilities of RISC chip, look ahead and Data
Server for High Speed Machining applications.
