5-Axis Machining in a Small Footprint

"The CT-350 5-axis vertical machining center (VMC) from Tongtai features state-of-the-art performance in a small footprint. The CT-350 has a high-end machine construction and performance at an affordable price," said a company spokesperson. The structure of the CT-350 is a "C" frame-type machine and was designed around mold-type machining centers to ensure rigidity during cutting. The column of the CT-350 has a wide span designed to make it torsion-resistant while cutting a 5-axis part. Rigidity is enhanced by using 45 mm roller type guideways and pre-tensioned, large-diameter ballscrews.

The CT-350's table size is 13.78" diameter and can handle a maximum load of 440 lbs. The integrated rotary table uses the roller gear cam in both the tilt and rotation axes. The roller gear cam design provides zero backlash, high rigidity and fast rotation speeds. The stroke on this machine is 15.75" in X, 20.08", in Y and 20.08" in Z. The A-axis stroke is +30° through -120°, and the C-axis stroke is 360° with rotation speeds of 40 RPM and 33 RPM, respectively. The CT-350 features rapid feedrates of 1,418 IPM in X and Y, and 1,182 IPM in Z. A 20 HP direct-drive 15,000 RPM Big Plus 40 taper spindle with air/oil mist lubrication is standard in the CT-350; an optional 20,000 RPM integral spindle is also available. The standard 24-position arm type tool changer is equipped with a roller gear cam mechanism to reduce tool change time to only 2 seconds. Larger 30- and 40-tool ATCs are optional.

The CT350 is equipped with a FANUC OiM-F CNC control to perform 4+1-axis cutting. However, if 5-axis simultaneous cutting is necessary, a FANUC 31iM-B5, Siemens 840D or Heidenhain iTNC-640 can be installed.

"The CT-350 is Tongtai's smaller 5-axis machining center with a small footprint for shops that need a 5-axis machine, but do not have the floor space for a larger machine tool," said the spokesperson.
