9 Shearing Machine Maintenance Checklists You Should Know!

shearing machine maintenance checklist

Regular maintenance is crucial for the optimal performance and longevity of shearing machines. Proper upkeep ensures the machine operates smoothly, reduces downtime, and minimizes the risk of breakdowns or malfunctions during operation. By adhering to a comprehensive shearing machine maintenance checklist, you can significantly enhance its lifespan while maximizing efficiency and productivity.

Today, we will provide you with nine essential maintenance tasks that should be included in your routine checklist. Follow these guidelines to keep your shearing machine running at its best!

Shearing Machine Maintenance Checklist

Proper maintenance ensures your sheet shearing machine’s longevity and optimal performance. As a vital piece of forging machinery in the metal processing industry, regular upkeep is essential for smooth operations. Here is an informative checklist to help maintain your shearing machine at its best!

  • Operating Rules

To ensure the safe and efficient operation of shearing machines, it is imperative to follow proper operating rules. These guidelines standardize work behavior and prioritize human-machine safety while minimizing product rework and scrap caused by operator negligence. Accidents can be prevented by strictly adhering to these protocols and ensuring workers’ well-being on the job.

Additionally, operating rules contribute to quality assurance by assigning material confirmation responsibilities and enforcing obedience to production processes for impeccable results. You can extend the lifespan of your shearing machine by maintaining correct machine use, following operating procedures, and regularly lubricating according to the chart.

  • Lubrication

You must lubricate your shearing machine properly to keep it running smoothly. Before each start-up, carefully follow the prescribed operating procedures and add clean, sediment-free lubricating oil according to the chart’s specifications. Regular maintenance involves adding lubricating oil during every shift for operators and applying it to rolling bearing parts semi-annually for mechanics. At the end of each workday, thoroughly clean and oil all machine tool components.

  • Cleanliness

Maintaining cleanliness in your shearing machine is paramount for several reasons:

  1. It enhances the machine’s longevity by protecting it from environmental elements and corrosion through regular application of rust-proof oil. A clean machine operates at its peak performance as filters are replaced and dust buildup on components is removed.
  2. Cleanliness ensures safety by preventing malfunctions or accidents caused by accumulated dirt and debris.
  3. Regular cleaning promotes efficiency with easier servicing while avoiding product overhauls and scraping due to negligence.
  4. Maintaining a clean hydraulic shearing machine system prevents blockages that can lead to costly failures.

  • Bearings and Electrical Safety

Proper maintenance of shearing machines includes handling the bearings and ensuring electrical safety. Regularly clean and inspect the bearings, applying rust-proof oil to unpainted areas for optimal performance. Follow the lubrication chart guidelines when adding lubricating oil, ensuring its cleanliness and freedom from sediment.

When operating the machine, prioritize electrical safety by opening the main control power supply lock on the cabinet first. Set switches to the “ON” position sequentially. Start with switch settings on electrical cabinets, then move to those on control panels.

During the shutdown, follow proper protocol. Turn off main control switches before rotating power switches on cabinets to the “OFF” position, securely locking them in place for added safety. It’s equally crucial that motors and electrical boxes remain clean while stabilizing zero-connecting units efficiently.

  • Inspection and Replacement

Regular inspection and timely parts replacement are essential to maintain a shearing machine effectively. Conduct routine inspections to check the condition of switches, safety devices, handles, belts, knobs, and keys for any damage or wear. Removing and examining worn-out parts is crucial if severe wear is detected during inspection.

When it comes to replacement, items that are unusable or fail to meet accuracy standards must be promptly replaced or repaired. Prioritize replacing any components that show signs of significant wear discovered during inspection.

  • Daily Preparation

Before starting your daily work, it is essential to prioritize the preparation of your shearing machine. The prep includes daily maintenance tasks such as applying lubrication and thoroughly cleaning the machine tools. By dedicating time to these essential steps, you can ensure maximum performance and durability for your machine.

  • Blade Maintenance

When you are maintaining the blade of the machine, don’t forget to regularly inspect the blade for any signs of dings, dents, or curvature. If it becomes dull or develops cracks, sharpening or replacing it promptly is necessary. The clearance between the upper and lower blades should be appropriate based on metal thickness.

Don’t overlook regular cleaning of the blade and applying anti-rust grease to unpainted parts consistently. It’s essential to securely fasten the blade plate while maintaining proximity to its surface carefully. Keep both upper and lower plate surfaces parallel for effective operation.

  • Cutting Limits

Understand the cutting limits of your shearing machine for optimal use. Follow the manufacturer’s guidelines to ensure you stay within the specified workpiece thickness and width parameters. Exceeding these limits can lead to costly damage.

Shearing machines apply force between a moving upper blade and a fixed lower blade, breaking metal plates into desired sizes based on required dimensions. To maintain this process, it’s important to maintain an appropriate clearance gap of around 10-15% relative to the sheet thickness. You should also bear in mind the stroke-per-minute limit. For example, RGS Mechanical Shear can produce up to 40 strokes per minute.

  • Authorized Operation

Properly authorized operations are paramount in maintaining shearing machines. Begin by strictly adhering to safe operating procedures and wearing necessary protective gear. Operators must thoroughly understand the machine’s structure and usage while ensuring a clear workspace with ample room.

Before commencing work, conduct a no-load test to ensure smooth tool movement up and down multiple times without any issues. During operation, never place hands on the cutting edge or touch foot buttons while handling materials or observing the line to prevent accidents.

In case of malfunctions, promptly press the emergency stop device for immediate action. After ensuring stability through power supply shutdowns, maintenance should only be carried out by professionals. Unauthorized individuals should not start or operate machinery unless granted proper permissions from personnel experienced with these tools.


In conclusion, a maintenance checklist for shearing machines provides essential guidelines to ensure efficiency and safety. Keeping machines oiled, clean, inspected, and replaced with new parts will extend their lifespans and prevent accidents or malfunctions. Regular maintenance not only enhances machine longevity but also improves efficiency and productivity.
