Discover Precisionvast’s detailed approach to ensuring exact dimensional accuracy in our casting processes, highlighting the specific tolerances for different casting methods
CNC Milling
CNC milling is a metal machining process in which a solid block of metal is machined into a finished product of the desired size through the use of 3-, 4-, and 5-axis milling machines and a variety of cutting tools.
CNC Turning
CNC turning is an effective manufacturing process more suited to producing round parts by removing material from metal bars or tubes. It includes cutting processes such as boring, grooving and facing.

This is a low carbon metal alloy with good mechanical, machinability and welding properties at a reasonable price. The hardness can also be increased by carburizing. Common grades are 4140, 1020, 1045, etc.https://precisionvast.com/carbon-steel-casting/
At the end of the CNC machining process, a smooth surface finish is achieved with a minimum roughness of Ra6.3. If no additional surface finish is required, the part will remain on the machined surface. CNC machining can also produce parts with higher surface finishes such as Ra3.2 or Ra1.6.
Overview: What is CNC Machining?
CNC Machining Basics
CNC (Computer Numerical Control) machining is a type of CNC machine tool machining, which is an automated machine tool equipped with a digital control system. It is a combination of machinery, automation, computers and other high technologies. Its basic components are the digital control program carrier, the machine tool unit, the drive spindle unit, the body of the machine tool and the safety guards.
CNC machining is done by controlling the machine tool based on programming (usually G-code).The G-code digital language controls the machining process of the CNC machine tool. It enables the tool control system to use different positional coordinates to control tool feed and spindle speed, coolant and other functions.
The correctness of the tool path can be analyzed by idling the CNC machine. When the digital program is entered into the machine, the fixture tool and workpiece are mounted. When the idle button is pressed, the spindle does not rotate and the table automatically runs along the programmed path. During this step, it is possible to find out if there is any contact between the tool and the workpiece or fixture. The control of the above operations is carried out by the cams, dies and indexing devices in analog form. The machining accuracy of the part is affected by the accuracy of the cams and molds, allowing for the machining of complex parts with a certain degree of flexibility and versatility, and long machining lead times. CNC machining to solve the complex and precise, small batch, multi-species processing problems, widely used in modern industry, greatly improving the production efficiency of enterprises.
CNC Machining FAQs
CNC Machining at Precisionvast is a process where computer-controlled machines produce precise parts from various materials like metals and plastics.
We use diverse materials, including metals like aluminum, titanium alloys, and steel, as well as plastics such as ABS and polycarbonate.
Our process involves creating a digital blueprint with CAD software, guiding our CNC machines to accurately produce the final product.
CNC machining offers higher efficiency, precision, less waste, and faster production compared to traditional methods.
CNC Milling removes material with a rotating tool, ideal for complex designs. CNC Turning, suitable for cylindrical parts, rotates the workpiece against a cutting tool.
The size limit is based on the machine used, accommodating both small and large parts.
The time varies based on complexity, size, and material, ranging from minutes for simple parts to hours or days for complex ones.
We typically achieve tolerances of ±0.005 mm, depending on machine accuracy, tool quality, and operator skill.
Industries like aerospace, automotive, medical devices, and electronics rely on our CNC machining services.
