CNC Turning Materials for Steel Parts

Steel 1018

Generally referred to as light steel, 1018 is very weldable as well fit to appear solidifying procedures such as carburizing. Once carburized, this product is generally utilized for gears, worms, mold, and mildew parts.

CNC  steel 4130

Steel 4130

When contrasted to normal moderate steel, this kind is commonly known as alloy steel due to its increased degrees of alloying components. This alloy includes chromium and also molybdenum as reinforcing aspects. These components significantly boost its mechanical homes. Applications can consist of taps, drills, and also aircraft engine mountings.

Steel 4140

The properties of steel 4140 and 4130 are similar, but the carbon content has been increased. The extra carbon increases its strength and gives it better hardening properties. Chromium is also added to improve corrosion resistance. Applications for Steel 4140 include thin-walled pressure vessels, spindles, and high-strength bolts.

Steel 4140 PH

4140PH steel is a pre-hardened version of 4140 steel with excellent mechanical strength and hardness properties. Its pre-hardening eliminates the need for post-processing heat treatment. This is ideal if you are concerned that the heat treatment of the part will cause unacceptable deformation of the finished part. Typical applications include shafts, mandrels, and dies.

Advantages of CNC Turning Steel Parts

CNC Turning Steel Parts
  • CNC turning is an automated work mode, which greatly improves work efficiency.
  • CNC turning is an automated work mode, which greatly improves work efficiency CNC turning in an automated process generally has much lower error rates and higher part quality than manual turning.
  • CNC turning is an automated work mode, which greatly improves work efficiency CNC turning is completely suitable for the production of small and medium-sized parts of 50-1000 scales.
  • CNC turning is an automated work mode, which greatly improves work efficiency Save labor costs, resulting in an overall reduction in parts costs.

What is CNC Turning?

Turning is a machining method in which a workpiece is rotationally machined using a cutting edge with a specific geometry. Usually, the workpiece rotates, and the tool with a single cutting edge moves along the machined surface. Compared with boring and milling, turning is the most common machining method in modern machining methods.

New, turning problems are limited almost exclusively to chip formation and machining costs. Controlled chip flow and chip breaking in turning means not only that the material being removed is removed from the machined area, but the chips must break in a controlled manner to remove as much cutting heat as possible from the cutting process.

Materials Finishes

  • The finish of steel is similar to that of stainless steel, generally shiny in appearance and slightly darker than aluminum alloys.
  • CNC turning steel parts can be media blasted again after machining or electropolished to a variety of surface finishes.

Process Characteristics of CNC Turning

  • It is easy to ensure the positional accuracy of each machining surface of the workpiece
  • The cutting process is relatively stable, avoiding inertial force and impact force, allowing the use of larger cutting amount, high-speed cutting, which is conducive to improving productivity
  • Suitable for the finishing of non-ferrous metal parts
  • When the surface roughness of non-ferrous metal parts is large and the Ra value is small, it is not suitable to use grinding, but turning or milling is required. High quality can be achieved when fine-turning with diamond turning tools.
