A CNC Press Brake is one of the most critical assets in any sheet metal fabrication unit. Whether you’re running a JFY Press Brake or any other advanced bending machine, consistent maintenance is the key to ensuring long-lasting accuracy, performance, and safety on the shop floor.
A well-maintained press brake delivers:
- Higher bending accuracy
- Stable performance
- Reduced downtime
- Longer tooling life
- Lower operating cost
To help your team keep the machine in top condition, here is a complete maintenance checklist recommended by UPANAL CNC and JFY engineers.
1. Daily Maintenance Checklist
✔ Clean the Machine Surface
Wipe down the body, ram, backgauge, and working area to remove dust, oil, and metal particles.
✔ Check Hydraulic Oil Level
Ensure the oil level is within the recommended mark. Low oil affects bending pressure and accuracy.
✔ Inspect Tooling Alignment
Confirm punches and dies are seated properly and aligned to avoid angle errors.
✔ Backgauge Cleaning
Clean the backgauge fingers and guide rails to ensure smooth movement.
✔ Check for Unusual Noises
Vibrations, rattling, or high-pitched noise often indicate mechanical or hydraulic issues.
2. Weekly Maintenance Checklist
✔ Lubricate Moving Parts
Apply lubricant to:
- Backgauge guideways
- Sliding surfaces
- Ball screws
- Ram guides
Smooth motion = accurate bending.
✔ Inspect Hydraulic Lines
Look for:
- Oil leaks
- Cracks in hoses
- Loose fittings
Fix immediately to prevent breakdowns.
✔ Check Safety Sensors
Ensure that:
- Light curtains
- Foot pedal switches
- Emergency stop buttons
are working properly.
✔ Inspect Cooling System
Confirm that the oil cooler is functioning properly to maintain stable oil temperature.
3. Monthly Maintenance Checklist
✔ Check Hydraulic Oil Quality
If oil appears dark, milky, or has particles → replace immediately.
✔ Recalibrate Ram Position
Ensures consistent bending angles and parallelism.
✔ Backgauge Accuracy Test
Verify positioning accuracy and repeatability.
✔ Tighten Bolts & Fasteners
High vibrations may loosen bolts on:
- Frame
- Backgauge
- Tool clamps
- Support arms
✔ Clean Electrical Panels
Dust buildup can cause overheating or short circuits.
Always do this with power OFF.
🔩 4. Yearly Maintenance Checklist
✔ Full Hydraulic Oil Replacement
Change oil based on usage or as per manufacturer recommendation.
✔ Replace Filters
Oil filters and air filters must be replaced annually for stable system performance.
✔ Full Machine Leveling
Machine must be re-leveled to avoid bending inaccuracies.
✔ Controller Backup & Software Update
Ensure that program files, parameters, tool libraries, and offsets are backed up and updated.
✔ Preventive Maintenance by Certified Engineers
A professional PM visit helps:
- Detect hidden issues
- Fine-tune machine performance
- Extend machine life

5. Tooling Care Tips
- Clean tooling before and after use
- Avoid mixing dented or worn-out dies
- Use only JFY-recommended punches and dies
- Store tooling in proper racks
Proper tooling care improves bending quality and prolongs die life.
6. Signs Your Press Brake Needs Immediate Attention
If you notice any of the following, stop and inspect:
- Inconsistent bending angles
- Slow ram movement
- Overheating hydraulic oil
- Backgauge errors
- Abnormal noise or vibration
- Oil leakage
Ignoring these signs can lead to expensive downtime.
Conclusion
A CNC Press Brake is a long-term investment—and regular maintenance ensures it continues to deliver peak performance. With the right care, your JFY Press Brake installed by UPANAL CNC can run reliably for years with minimal downtime and maximum accuracy.
