CNC Turning Machining

What is CNC turning?

  • Turning is a cutting process that is performed by means of the normal main movement due to the rotation of the workpiece to create a cutting motion combined with the feed motion.
  • CNC is an acronym for Computer Numerical Control, which can be understood as numerical control with the support of a computer.
  • CNC turning is a machining method using computer numerical control technology to achieve high accuracy and fast working speed

Intech Precision Mechanical is a member of Intech Group, which has equipped with modern lathes and successfully applied CNC turning technologies to produce high-precision product details and beautiful aesthetics to meet the needs of customers. meet the increasingly demanding market needs.

Role of CNC turning:


Turning is an indispensable machining process in any mechanical processing plant. CNC turning has many outstanding advantages compared to traditional universal lathes:

  • Machining difficult and complex profiles that an ordinary universal machine cannot do.
  • Bringing high economic efficiency and high quality products.

Intech Mechanical is a multidisciplinary corporation in the field of high precision mechanics, industrial automation and technology, so Intech Precision Mechanical  is an important and indispensable piece to meet customer needs of Intech, and also to reinforce Intech's high-tech products to ensure quality

What included in the basic CNC turning machining?


To produce a high-quality CNC turning product, it requires going through many different steps and different stages, Intech Precision Mechanical  only offers the basic steps for those who are new to the precision mechanical industry refer to more;

1. Checking workpieces against drawing and checking machining materials:


Measuring the size of the workpieces compared to the size on the drawing, and checking the machining materials.

2. Rough turning of workpieces:


Based on the exact size of the part on the drawing and the actual measured size on the workpieces, decide how to turn the workpieces.

3. Checking design data ---> Designing model on CAD:


Checking on detailed drawings the contents of size, shape, roughness and processing materials.

4. CAM Programming (Translating CAD files into code for machining):

  • CAM is the successor of computer-aided engineering (CAE) and is often used in tandem with computer-aided design (CAD).
  • Checking the CAM program.

5. Installation of CNC lathes:

  • Checking detailed machining dimensions.
  • Removing unnecessary programs from your computer. CNC
  • programs can vary by day-to-day work, so care should be taken to remove existing programs from the machine.
  • Setting knife.
  • Setting the X direction so that the center of the chuck coincides with the drill bit.
  • Adjusting tool length.
  • Mounting the knife and jigs on the chuck.

6. CNC lathe operation:

  • Operating detailed machining machines

  • Measuring, evaluating, and checking the dimensions according to the required drawings.


What are the strengths of CNC turning technology?

  • Reducing the factor that depends on the technical skills of the machinist.
  • The operation is based on the available programmed software, so the working efficiency of CNC turning is high, the accuracy is high without requiring too much skill of the technician.
  • Humans only play a supervisory role, not directly conducting mechanical turning.
  • Reducing manpower, lowering production costs, and at the same time reducing product costs.
  • Providing uniform accuracy for each machined product.


In order to promote the strengths and limit the weaknesses, Intech Precision Mechanical has equipped with a combination of high quality CNC machining machines such as: HASS CNC milling machine, Focus CNC FBL-200L lathe, CNC wire cutting machine, CNC grinding machine, CNC laser cutting machine, CNC folding machine, CNC punching machine,...;

The right products on any machine, Intech Precision Mechanical will process on that machine to promote the strengths to make the quality, price, and progress of that product guaranteed and optimal.


10 basic steps to operate a CNC lathe:

There are many different types of CNC lathes and here Intech Precision Mechanical will present the general steps to operate the Focus CNC FBL-200L CNC lathe for your reference;

Step 1: Turning on the machine: Turning on the switch to open the machine.

Step 2: Returning to the benchmark: Making sure the table and the tool shaft will run to the machine's reference point.

Step 3: Selecting the knife: Depending on the purpose of processing different details, choose the appropriate knife.

Step 4: Setting the workpiece: Setting up the workpiece, setting the mounting type; setting the origin of coordinates for parts.

Step 5: Closing the machine door: After attaching the part, select the tool, the origin of coordinates 0 for the part, close the machine door (by pressing the close button of the machine).

Step 6: Adjusting the parameters.

Step 7: Safe tool compensation: Selecting the tool length and tool diameter compensation mode.

Step 8: Loading the program into the machine: Selecting the pre-programmed machining program.

Step 9: Knife compensation for machining

Step 10: Processing: The machine processes details according to the established program.
