The machine is suitable for boring and roller burnishing of the hydraulic cylinder workpieces. After process, the diameter precision of the workpieces can reach IT8-IT9, and the surface roughness can reach Ra0.2-Ra0.4μm after roller burnishing.

The machine is mated with Siemens or Fanuc CNC controller and the boring box is mated with servo spindle motor. The spindle has stepless speed with high accuracy for its bearing and high rigidity. The feedbox adopts servo motor and high accuracy ball screw, while the whole casting of the bed and double rectangle guide ways assure its high rigidity, and the machine is also mated with chip conveyer with good leak-proof performance. The coolant filter adopts three steps filtration in the accuracy up to 50μm.

Mated with automatic sizing combined tools, the machine is ideal deep-hole process equipment with high accuracy and high efficiency. For instance, to process a inner hole with a diameter of Φ160:diameter allowance 1mm (after rough process), feed speed can reach 500~1250mm/min;the roughness can reach Ra0.2-0.4μm,the size accuracy can reach IT8~IT9,the process allowance of the three combined tools for diameter can reach 10mm,and the process efficiency can reach 150~350mm/min. The process efficiency is 3-5 times of the traditional deep-hole machine.
