CNC milling/lathe machines are multi-tasking, multi-functional CNC machines used to produce complex workpieces in a single operation. These machines are capable of turning workpieces and applying rotary tooling operations such as cross drilling, tapping, grooving and milling. Parts requiring multiple operations can be machined in one setup, especially if sub-spindles allow parts to be passed from one spindle to another during machining, essentially machining two parts at the same time. All of these processes combined in one complete cycle can result in faster part manufacturing, increased accuracy (no re-clamping) and less setup time.Absolute's CNC milling/turning centers offer these benefits at a very affordable price.

What is CNC turning?
CNC turning is used to create cylindrical parts. During CNC turning, the material is rotated at high speed while the single point cutting tool begins to subtract material from the workpiece. CNC turning is most commonly used on metal alloys. benefits of CNC turning include high levels of accuracy, repeatability, speed and cost.
What is CNC Milling?
CNC milling is used to produce parts that do not have cylindrical features. The workpiece is held in place while the tool rotates around the material to produce the desired shape. CNC milling can be used to create a finished product from raw material or as an auxiliary process to add definition. CNC milling can be used on a variety of materials including metals, glass, plastics, ceramics, elastomers and composites. benefits of CNC milling include higher productivity, accuracy and precision.

Sheet metal laser cutting is working by irradiating the focused high-energy and high-density laser beam to the workpiece, and make the irradiated material molten, vaporized, ablated. Meanwhile, the high speed airflow will blow away the molten material, and realize the cutting on the workpiece.
High volume Manufacturing is based on the interchangeability of products or parts. The rigid production line greatly improves production efficiency and reduces production costs. Its notable features are stable product structure and high degree of automation.
Steel is one of the most commonly used materials in CNC milling and CNC turning. The primary element of steel is iron (from iron ore) combined with varying amounts of other elements to create a variety of steel types, producing metals with a wide range of physical properties to meet the requirements of a variety of applications.
Precision welding, such as TIG welding, produces clean and exceptionally accurate welds. Precision welds are defined as the purest welds for joining tubes and fittings on both metals and plastics. A precision weld’s bead fully penetrates the inner wall of a tube, pipe, or fitting.
CNC milling and turning are the two most common CNC machining processes. CNC milling involves the use of rotating tools to remove material from the workpiece. CNC turning, on the other hand, uses a non-rotating tool to shape the workpiece. Both milling and turning can be performed on a variety of materials, including metals, plastics and composites. In general, CNC milling is better suited for creating flat surfaces, while CNC turning is better suited for creating cylindrical shapes. However, both processes can be used to create a wide variety of shapes and geometries.
CNC lathes and milling machines are computer-controlled tools used to create precise, complex parts for a variety of industries. These machines work by using rotary cutting tools to remove material from the workpiece. Turning processes are used to create cylindrical parts, while milling processes are used to create flat or irregularly shaped surfaces. Both processes can be performed on a variety of materials, including metals, plastics and composites.
Turning and milling machines combine the functions of a lathe and a milling machine. These machines are often used to produce small, complex parts, such as those used in the electronics or medical industries.
To make a part, lathes and mills first start with a piece of material called a workpiece. The machines then use a variety of tools to remove the material from the workpiece and shape it into the desired shape. The turning process involves rotating the workpiece while using cutting tools to remove the material. The milling process, on the other hand, involves moving the workpiece past the rotating tool. These two processes can be performed simultaneously on both lathes and milling machines, resulting in increased efficiency and precision.
Their ability to produce extremely precise parts makes them a must-have tool for many manufacturing industries. In addition to being more accurate than manual turning and milling methods, CNC machines can produce parts faster and with less waste. As a result, CNC lathes and milling machines have become an important part of the global manufacturing business.
CNC lathes and milling machines are used in a variety of industries to make precision parts. Automotive, aerospace and medical manufacturers use CNC machines to make engine parts, drive shafts and surgical instruments.
For example, aerospace companies use CNC machines to make parts for aircraft and satellites. Automotive companies use CNC machines to make parts for cars and trucks. Medical companies use CNC machines to make implants and prosthetics. In the electronics industry, CNC machines are used to produce circuit boards and other components.
Finishing the surface of a part is the final step required in the CNC machining process. Finishing is used to eliminate defects, increase resistance and strength, improve part appearance, and more. Here are some common surface finishes for CNC machined parts.
Sandblasting: The sandblasting process adds a satin or matte finish to CNC parts. Matte finishes are accomplished by spraying glass beads on the part using a pressurized air gun.
Powder Coating: Parts are powder coated with a thin protective layer that adds strength and wear resistance. In the powder coating process, the part is first primed with a chromate or phosphate coating. Next, the part receives a dry powder coating from an electrostatic gun. Finally, the part is cured in an oven.
Anodizing: CNC parts are anodized to form an oxide layer that increases their density, thickness and durability. Anodizing also makes the part non-conductive. During the anodizing process, the part is placed in an acidic electrolyte bath used as an anode. A cathode is added to the part and current is passed through the acid. Oxygen ions in the electrolyte and atoms in the alloy bond along the surface of the part.
Surface grinding: The surface grinding process is used when specific dimensions or a precise finish is required. Surface grinding removes material by using a high-speed grinding wheel as a cutting tool.
Polishing: Polishing techniques improve the size and accuracy of a part while producing a mirror finish. Polishing tools and abrasive materials are used to obtain a smooth surface.
Passivation: The corrosion resistance of CNC machined parts is improved when the passivation process is completed. Passivation can include spraying, cycling in chemical solutions, gel application or tank dipping.
Chemfilm: Chemfilm finishes are chemical conversion coatings that increase the corrosion resistance of aluminum substrates and serve as a base for organic coatings. Parts are impregnated, brushed or sprayed with a chemical film layer.
Vacuum Metallization: The vacuum metallization process produces a mirror or decorative uniform finish, while also improving the barrier properties to heat, air, light or water. In the vacuum metallization process, the part is placed in an enclosed chamber where metal vapor adheres to and covers the part.
Screen Printing: Screen printing is used to transfer designs or logos onto the part. When a part is screen printed, a grid is used to apply the ink to the surface, but only to the permeable areas not covered by the blocking stencil.
Plating: Plating increases the corrosion and wear resistance, electrical conductivity and reflectivity of the part. During the plating process, the part is immersed in an electrolyte bath containing the material that will be used to coat the metal. The electrical charge causes the material to transfer to the part, resulting in a uniform metallic coating.
Tumbling: Tumbling or ultrasonic polishing removes any sharp points or edges from the machined part. During the tumbling process, the part is placed in a bucket with media, water and cleaner. The barrel is tumbled at different speeds depending on the desired finish.
Painting: Painting can be used to add color, varnish or ink to the part. Painting methods may include spraying using equipment to paint parts.
As-Milled: As-milled or as-machined products do not require secondary processing. They will still have visible imperfections and may have a rough surface.
