Types of Machines for Cutting Granite
Bridge Saw
Bridge saws are widely used for cutting large granite slabs. They feature a diamond blade mounted on a bridge structure, allowing for precise vertical and horizontal cuts. The machine operates with high accuracy, making it ideal for fabricators who require consistent results. Companies like BACA Systems specialize in these machines, offering various models tailored for different cutting needs.
CNC Saw
CNC (Computer Numerical Control) saws provide advanced cutting capabilities for granite. With 5-axis technology, these machines can create intricate designs and complex shapes that are hard to achieve with traditional saws. Park Industries is known for its superior CNC saws, which enhance productivity while ensuring precision in every cut.
Waterjet Cutter
Waterjet cutters utilize high-pressure water mixed with abrasives to cut through granite. This method minimizes thermal stress and edge chipping, making it suitable for delicate designs. The versatility of waterjet cutters allows them to work on various materials beyond granite, including glass and metal. They are an excellent option for those who require flexibility in their cutting projects.
Bridge Type CNC Machine
The bridge type CNC machine combines the benefits of a bridge saw and CNC technology, allowing for both automatic cutting and versatility in handling different stone types. The Schind 16651 model offers features like a hydraulic damper table and automated dimensioning, making it user-friendly and efficient for granite fabricators.
Tile Cutter
For smaller granite pieces and tiles, tile cutters provide an efficient solution. These compact machines are designed for easy handling and portability, making them suitable for on-site work. While they may not offer the same precision as larger machines, they are perfect for quick jobs and smaller projects.
Handheld Saw
Handheld saws are ideal for cutting granite on the go. Their portability allows workers to make quick cuts without the need for large equipment. While they may not provide the same level of precision as other machines, they are invaluable for smaller jobs and renovation projects.
Key Features to Consider
When selecting a granite cutting machine, consider the following key features:
- Precision: Look for machines that guarantee high accuracy, especially for complex designs.
- Power and Speed: Evaluate the motor power and cutting speed to ensure the machine meets your production requirements.
- Ease of Use: Choose machines that offer user-friendly interfaces and automation features for efficient operation.
- Durability: Ensure the machine is built from high-quality materials to withstand rigorous use.
- Maintenance: Consider how easy the machine is to maintain, including access to parts and service support.
