Important Maintenance Tips for Doosan Puma Series Lathes

Doosan Puma is a well known series of CNC lathe machines that are used by manufacturers across several industries. These machines are widely appreciated for their precision machining capabilities, heavy duty material handling power, and also their long machining life. But that long life can be achieved by a machining shop when the machine is maintained properly.

No CNC machine will be able to perform without proper maintenance, and the Doosan Puma CNC machines are no exception. So, in this blog, we will discuss the top Doosan Puma CNC maintenance tips that will help to give the machines a better running life.

Top Doosan Puma CNC Maintenance Tips for Better Machining Experience:

Here are some of the major factors that should be included in your Doosan Puma preventive maintenance checklist for extending Doosan Puma lathe life:

1. Cleanliness and Chip Management:

The first factor that should be included in the Doosan Puma CNC maintenance tips is proper cleaning and chip management. At the end of every machining shift, the machine should be properly cleaned and make sure that no waste chips are left in the machine bed, as accumulated chips cause damaging of slideways, clog coolant lines, and cause premature wear.

2. Monitoring Lubrication Levels:

The next factor that one should keep in mind is proper monitoring of the lubrication system of the CNC machine. The Puma series machine features an automatic lubrication system, and the lubrication system is very important for the proper health of the boxways and ball screws of the machines. You will have to check oil levels daily and make sure the automatic lubrication system is cycling properly. One of the Doosan Puma service best practices is to use the right lubricant mentioned by the company.

3. Take Proper Care of Spindle:

The spindle is one of the most important parts of the CNC machine, and one should give proper attention to Doosan Puma spindle maintenance for better health and performance. One should always give proper attention to whether the CNC spindle is having issues like noise, vibration, and overheating during machining operations.

Doing a daily spindle warm-up run before doing the actual machining can be highly beneficial for your CNC machine’s life. Run the Puma’s spindle for 10-15 minutes at the start of the day with low RPM, and gradually increase it.

4. Do Proper Coolant Maintenance:

The coolant quality has a direct impact on different factors of the CNC machine, like the tool life, surface finish, and machine cleanliness. Low coolant concentration might lead to rusting of internal elements, while high concentration can be hazardous for operators.

Check the coolant concentration level on a regular basis and make sure there is no contamination or foul odors. Dirty or degraded coolant can cause corrosion and clog coolant lines.

5. Inspect Turret Alignment and Indexing:

The Turret of the Puma CNC machines is incredibly robust, but it still needs proper inspection on a regular basis. It is responsible for accurate tool positioning. Check for smooth indexing and also listen for abnormal sounds during tool changes. Catching even a small misalignment beforehand will prevent long-term wear.

6. Take Care of Chuck and Jaw Condition:

Lastly, one of the important Doosan Puma CNC maintenance tips is checking the chuck and jaw of the machine. The chuck assembly faces constant stress during turning operations. Inspect jaws for wear, chips, and deformation. Clean the chuck regularly to prevent any kind of chip buildup.

Overall, the maintenance of the Doosan Puma CNC machine is pretty straightforward. So, if you are looking to buy a CNC lathe of the Doosan Puma Series, then check the collection of MachineStation.

FAQs:

1. How often should routine maintenance be performed on a Doosan Puma series lathe?

Basic inspections such as lubrication checks, chip removal, and visual inspections are typically done daily. Weekly and monthly tasks usually focus on filters, coolant condition, and system checks, while preventive maintenance follows the manufacturer’s recommended schedule.

2. What should operators listen for during daily operation?

Unusual noises such as grinding, knocking, or inconsistent turret indexing can indicate wear or mechanical issues. Identifying these early allows for inspection before issues escalate.

3. How does chip management impact machine maintenance?

Poor chip evacuation can lead to conveyor jams, coolant overflow, and internal buildup. Regular cleaning of conveyors and augers supports smoother machine operation.
