The Kent CNC Heavy Duty Boring Turning Center Series provides 2 excellent configurations for heavy duty turning for large parts. This series is equipped with big hollow bores ideal for large diameter pipe-type work. The Kent CNC Large Bore Turning Center Series features up to 400 inches of bed, 12 inches in spindle bore diameter, and over 15,000 lbs of turning capacity. Designed for rigidity and precision, the Kent CNC large bore turning series can be equipped with up to 35 HP of spindle motor to perform heavy duty cutting and deep hole machining. In addition, this series is equipped with big hollow bores ideal for large diameter pipe-type work. Roller brackets are installed for heavy duty large workpieces with up to 20 inches in diameter.

One-Piece Fabricated Bed

The massive bed is built from high quality Meehanite cast iron, and stress relieved for prolonged heavy duty operations. In addition, the bedways are induction hardened to hardness of HRC 52~54, and precision ground to achieve high straightness accuracy. The bed is also designed with triple “V” and one flat slideway to increase machining dependability and precision.

Rigid Spindle

All gears are manufactured from high quality nickel chrome-molybdenum alloy steel in combination with a large module design. With the increased tooth module and gear width, the gears have larger contact surfaces for more durability and longer lifespan.

Our precision lathes are turned for ultimate performance through dynamic balance testing. The spindle is supported by high precision taper roller bearings. Also, an auto-lubrication system is equipped for headstock gears and spindle bearings.

Turret

The TA Series comes standard with an H4 hydraulic turret which holds 4 tools and can be quickly swiveled to cutting position. Optionally, a V8 hydraulic turret can be equipped to accommodate up to 8 tools. It also features high indexing accuracy, random tool selection and fast tool change times.
