Cnc Turning: 1 to 1,000 units/days

Cnc Turning is used to machining rotating parts. The parts are clamped on the main shaft of the machine through a three-grip chuck and rotated at a high speed. Then, the turning tool is used to follow the bus of the rotating body to cut out the parts appearance. The lathe can also process internal holes, threads, bites, etc., the latter two are low-speed machining.

Machining Process

The main Served shafts, disks, sleeves and other workpieces with rotating surfaces.

  1. When turning stepped shafts, in order to ensure rigidity during turning, generally the part with the larger diameter should be turned first and the part with the smaller diameter should be turned after.
  2. When grooving on the workpiece of the shaft, it should be performed before finishing turning to prevent deformation of the workpiece.
  3. When finishing turning a shaft with a thread, generally the unthreaded part should be finished after the thread is machined.
  4. Before drilling, the end face of the workpiece should be turned flat. If necessary, punch the center hole first.
  5. When drilling a deep hole, drill the pilot hole first.
  6. When turning (Φ10—Φ20) ㎜ holes, the diameter of the tool holder should be 0.6-0.7 times the diameter of the machined hole; when processing holes larger than Φ20㎜, the tool holder for clamping the tool head should generally be used.
  7. When turning multiple threads or multiple worms, perform trial cutting after adjusting the exchange gear.
  8. When using an automatic lathe, adjust the relative position of the tool and the workpiece according to the machine adjustment card. After the adjustment, test turning is required. The first piece can be machined only after it is qualified. During the machining, pay attention to tool wear and workpiece size and surface roughness degree.
  9. When turning on a vertical lathe, after the tool post is adjusted, do not move the beam at will.
  10. When the relevant surface of the workpiece has position tolerance requirements, try to complete turning in one clamping.
  11. When turning cylindrical gear tooth blanks, the hole and reference end face must be machined in one setup. If necessary, the marking line should be turned out near the gear index circle on the end face.

Our CNC turning center near Dongguan, CN is equipped with hard-wired controls and tools to minimize set-up times, as well as automatic part catching and indexing capabilities. Our CNC turning machines also possess magazine bar feeders to increase production efficiency. All of these features make our innovative metal turning machinery well-suited for the fabrication of highly complex, precision parts.

Upholding a (+/-) 0.0005” precision tolerance, our advanced lathe turning equipment can process bar stock up to 10” in diameter and 44” in length. And, we can produce oem parts from a variety of materials, including stainless steel, acrylic, and fiberglass reinforced plastics.
