Aluminum CNC Lathe Turning Part CNC Machining Custom OEM Part CNC Machining
Service Stainless Steel CNC Parts
CNC turning is a machining process that involves cutting material to create round shapes,
typically using a CNC Lathe.
In this process, the workpiece is placed inside the lathe and rotates while a cutting tool removes
material until only the desired shape remains.
CNC turning is particularly well-suited for cylindrical parts and is usually performed using round
rod material.
However, square and hexagonal bar stock can also be used depending on the requirements.
The primary goal of CNC turning is to manufacture parts with shapes achievable by feeding a
cutter into a rotating bar of raw material.
It can also be employed to reduce the diameter of a workpiece to a specific dimension.
Lathe turning is commonly used for shaping metal or wood.
CNC lathes find applications in metalworking, woodworking, and metal spinning processes.
They produce precise round shapes, often with accurate outer diameter (OD) and inner
diameter (ID) dimensions.
Product Details
CNC turning machines are capable of cutting a wide range of materials, including aluminum,
bronze, copper, ceramics, plywood, various steel alloys, stone, wood, zinc, and various
engineering materials.
This versatility makes them an excellent choice for crafting prototypes during product
development. Furthermore, CNC milling allows for precise and rapid adjustments until the
desired final product is achieved.
| Common Materials | |
| Name | Description |
| Aluminum | High machinability and ductility, good strength-to-weight ratio. |
| Stainless steel | High tensile strength, corrosion and temperature resistant. |
| Mild steel | High machinability and weldability, high stiffness. |
| Brass | Low friction, excellent electrical conductivity, golden appearance. |

Our tolerances for machined parts are typically within +0.005"/-0.005" for most metal geometries,
and within +/- 0.010" for plastics.
However, tolerances may vary for larger parts, especially when maintaining flatness over extensive
sections post-heat treatment.
