8 Simple Tips to Follow When Operating CNC Lathe Machines

Does your industry require a lathe machine with CNC compatibility? Although the CNC component's software element makes lathing easier, it doesn't mean the device won't need regular maintenance to perform correctly.

To operate a lathe machine properly, follow these tips or precautions to lower the risk of injury and the cost of replacement parts.

What is a CNC Lathe Machine?

A CNC Lathe Machine uses CNC or Computer Numerical Control technology to design instructions for the machine to move. Lathe machines clamp onto the material to keep it in place, use spindles to rotate, and initiate a cutting tool to shave away metal and wood. Used mostly for machining parts like pipes and shafts, lathe machines can achieve symmetry using a 2-axis tool, but a 3-axis tool can mount material for radial and axial operational directions.

Industries that wish to purchase a lathe machine for sale have a wide selection to choose from, including ones with threading and taper attachments. Any industry that requires shaping, sanding, drilling, turning, knurling, deforming, or cutting will benefit from using a lathe.

How to Safely Use a CNC Lathe Machine

1. Load the Program Before Use

CNC machines use a program to conduct tasks, but it can't start creating parts without a part program already loaded into the software. Newer machines use a USB drive to transfer information back and forth, but some older machines may need a serial connection directly to the computer. Ancient machines may even require a floppy disk, but it's best to avoid these lathing instruments. Floppy disk run technology has limited functionality or complexity.

2. Ensure the Work Piece is Secure

Before turning the machine on, you must ensure that the workpiece is tightly secure into the lathe. The part that grips the material, also known as the collector chuck, needs to clamp down to the point that it can't be removed by human force but not so tight that it ruins the workpiece.

3. Read the Parts Program or Programmer to Load Appropriate Parts

Similar to any computer program, CNC machines cannot create the finished product you desire if the proper programming or parts aren't loaded. Consult the parts program or manual to ensure the machine has everything it needs to complete the job, or ask a programmer. The parts won't work unless the coolant pump is on and the nozzle is hitting the tips of each tool.

4. Set Offsets for Tools

All parts need to be in a specific location to fit with the X and Z axis of the material you're using. Most part programs will let you know when the tools are in the correct location by beeping or refusing to start until the tools are offset correctly. Of course, the workpiece must also offset.

5. Keep the Cutting Tool Sharp

Inspect that cutting tool before starting the lathe to make sure it can cut through the material you're using. You should replace the cutting tool consistently with heavy use. A dull cutting tool can produce a faulty piece or dislodge large metal chunks that could fly off and injure you.

6. Wear Safety Equipment

Safety equipment, like impact-resistant safety glasses, gloves, and headgear should be worn to prevent injury. Never wear loose-fitting clothing or jewelry that has the potential to get dislodged in the machine. Lathes are dangerous and should be used with caution.

7. Maintain an Obstruction-Free Environment 

Since lathes are elevated away from the ground, they don't typically create a lot of mess, but you should still look around at the floor before operating one. Remove any tools, power cords, or boxes that could cause you to trip into the machine or onto the floor.

8. Clean Scrap Material After Using the Lathe

After running the part program successfully (always stop the machine if a problem occurs), remove any excess metal or wood from the workspace. When the lathe is turned off and unplugged, use a vacuum to suck up any small bits of material that can't be removed by hand.
