How To Program A Double-column CNC Vertical Lathe?

The double-column CNC vertical lathe is an efficient and high-precision machine tool that is receiving more and more attention and application. This kind of machine tool plays an irreplaceable and important role in processing large workpieces and workpieces with special shapes such as pipes and cylinders. However, due to the difficulty of programming, many operators are not proficient enough in programming double-column CNC vertical lathes. So, how to program the double-column CNC vertical lathe? Let's find out below.
1. Necessary knowledge before programming
Before programming a double-column CNC vertical lathe, you first need to obtain basic knowledge. The knowledge that needs to be mastered includes: the structure of machine tools, basic control theory, operating instructions such as G code and M code. Only by being familiar with this knowledge can you write and debug programs and improve processing efficiency.
2. Basic programming steps
After mastering the necessary knowledge, you can proceed to the specific programming steps. Before programming, you need to configure the machine tool parameters and related parameters of the workpiece to be processed, and then follow the following steps:
(1) Determine the spindle speed and feed speed, and set the G codes of the spindle and feed;
(2) According to the shape and geometric dimensions of the workpiece, write the processing contour and main cutting tool path in the control program;
(3) Select appropriate cutting tools and fixtures, and set cutting parameters according to workpiece requirements;
(4) Input the written program into the CNC system for verification and debugging;
(5) Carry out processing operations in manual, semi-automatic or automatic modes.
3. Things to note when writing programs
When writing a program, you need to pay attention to the following points:
(1) Determine the coordinate system and coordinate direction, and select the corresponding coordinate system origin and coordinate axis according to programming needs;
(2) Try to use straight lines or simple curves to draw points, and do not use a large number of multi-segment polylines and curves to avoid affecting the processing accuracy;
(3) Set cutting parameters, compensation amount, speed and feed according to specific operating needs.
Programming of double-column CNC vertical lathes is generally difficult, but in fact as long as you master the relevant knowledge and skills, you can easily write corresponding programs to improve processing efficiency and quality. There are many details that need to be paid attention to during the entire programming process, but as long as you master the methods and precautions, you can better apply this efficient and high-precision machine tool.
