The Ultimate Guide to CNC Chip Conveyors
In the world of CNC machining, the effective management of metal chips is crucial for maintaining production efficiency and machine longevity. Chip conveyors are essential tools designed to remove chips and debris generated during the machining process, ensuring that machines operate smoothly without interruptions. This guide will explore the different types of chip conveyors, their applications, and how to select the best option for your CNC machine.
Types of CNC Chip Conveyors
| Type of Conveyor | Description | Best For | Pros | Cons |
|---|---|---|---|---|
| Hinge Belt Conveyors | Features a series of hinged steel belts to transport chips. | General machining operations | Robust, handles various chip types, low maintenance | Can be bulky |
| Scraper Belt Conveyors | Uses a flat belt with scrapers to move chips. | Smaller machines or tight spaces | Compact design, effective for small chips | Limited chip type handling |
| Magnetic Conveyors | Utilizes magnets to lift and transport ferrous chips. | Metalworking with ferrous materials | Efficient for metal chips, minimal wear | Not suitable for non-ferrous chips |
| Auger Conveyors | Employs a rotating screw to move chips. | High volume chip removal | Great for thick chips, versatile | Can be less efficient for fines |
Understanding Chip Conveyor Technologies
Hinge Belt Conveyors
Hinge belt conveyors are designed for heavy-duty applications. They consist of a series of interlocking metal plates that are hinged together, allowing for continuous movement even under heavy loads. These conveyors efficiently remove chips, reducing the frequency of maintenance and downtime. Hennig Worldwide (hennigworldwide.com) offers a variety of hinge belt conveyors tailored for different machining needs.
Scraper Belt Conveyors
For smaller machines or those with restricted space, scraper belt conveyors are ideal. They feature a flat belt with scrapers attached, which effectively removes chips and shavings from the machine bed. Their compact design makes them suitable for tight spaces while still maintaining efficient chip removal.
Magnetic Conveyors
Magnetic conveyors are designed to transport ferrous chips using magnets. This technology is particularly useful in environments where metal chips are prevalent. Jorgensen Conveyors (www.jorgensenconveyors.com) provides magnetic conveyor systems that enhance productivity by ensuring that chips are removed efficiently without the use of additional energy.
Auger Conveyors
Auger conveyors utilize a screw-like mechanism to move chips. They are best suited for applications requiring the removal of thick chips and are often used in high-volume machining operations. These conveyors are excellent for processing chips for recycling, making them a sustainable choice for manufacturers.
Applications of CNC Chip Conveyors
Chip conveyors are versatile and can be integrated into various machining processes. Key applications include:
- Machining Centers: Chip conveyors prevent machine jams by continuously removing chips, ensuring optimal performance.
- Lathes: They help maintain cleanliness and efficiency by transporting chips away from the work area.
- Milling Machines: Chip conveyors are essential for both horizontal and vertical milling machines, handling chips effectively to minimize downtime.
Selecting the Right Chip Conveyor
When choosing a chip conveyor for CNC machines, consider the following factors:
- Chip Type: Different chips require different conveyor types. For example, ferrous chips are best handled by magnetic conveyors, while hinge belt conveyors are more versatile.
- Space Constraints: Ensure that the selected conveyor fits within the available space without compromising machine access.
- Volume of Chips: High-volume operations may benefit from auger conveyors or larger hinge belt systems.
- Integration Needs: Some systems may require integration with existing machine controls or automation. Hennig Worldwide (hennigworldwide.com) provides custom solutions for such needs.
