Little Giant's machine tool introduces high-speed and high-precision full-function CNC lathe
Japan's Yamazaki Mazak subsidiary, Little Giant Machine Tool Co., Ltd., has introduced a new high-speed and high-precision full-function CNC lathe model QTN 100-II, set to begin production at the company’s facility in September this year. This latest addition expands the range of CNC lathes offered by Little Giant, now covering chuck sizes from 6 inches up to 15 inches, making it more versatile for a wide array of industrial applications.
The QTN 100-II is designed with enhanced performance in speed, precision, functionality, user-friendliness, and space efficiency. It is particularly well-suited for processing high-volume, high-accuracy components such as automotive parts, gears, and other precision-engineered components. The machine is ideal for manufacturers looking to boost productivity while maintaining tight tolerances and consistent quality.
Powered by advanced electric spindle technology, the QTN 100-II features a spindle speed of 6,000 revolutions per minute, allowing it to handle both low-speed heavy-duty cutting and high-speed, high-power machining. The machine uses smooth high-gain servo control and high-performance AC servo motors, enabling fast and vibration-free acceleration and deceleration. The X-axis moves at 30 meters per minute, while the Z-axis reaches 33 meters per minute, significantly improving cycle times.
The QTN 100-II also comes equipped with a high-speed, high-precision 12-bit turret that allows tool changes in just 0.18 seconds, greatly enhancing production efficiency. Additionally, the intelligent tailstock, driven by a servo motor, offers automatic positioning and pressure adjustment, ensuring precise and reliable support during machining operations.
To further enhance automation, the machine includes a tool measuring device that supports the automated processing of complete part sets and integrates with bar feeders for workpiece collection. It also features MAZAK’s latest MAZATROL MATRIX CNC system, which offers an intuitive human-machine dialogue programming interface. The system includes functions like interference checking, intelligent safety protection, vibration suppression, and sound alerts, making it easier and safer to operate.
With these advanced features, the QTN 100-II represents a significant step forward in CNC machining technology, offering manufacturers a powerful, efficient, and user-friendly solution for modern manufacturing needs.
Fuel Dispenser Mechanical Accessories
Fuel Dispenser Mechanical Accessories – Classification Overview
Â
Mechanical accessories are the core structural and functional components that ensure the reliable operation, safety, and durability of fuel dispensers. These parts are primarily responsible for fuel delivery, flow control, leak prevention, and physical support. Fuel dispenser mechanical accessories can be classified by function, installation location, material type, and application environment.
Â
1. By Function:
• Fuel Nozzles:
Manual or automatic shut-off nozzles designed for controlled and accurate fuel dispensing.
• Fuel Hoses:
Flexible, pressure-resistant hoses for safe fuel flow between the dispenser and vehicle tank; available in single or vapor-return types.
• Breakaway Couplings:
Safety devices that disconnect in case of excessive tension, preventing fuel spills and equipment damage.
• Swivels:
Allow for flexible nozzle movement, reducing hose wear and improving user convenience.
• Flow Meters:
Measure the volume of fuel dispensed; available in gear, vane, or piston types.
• Filters and Strainers:
Remove impurities from fuel to protect internal components and maintain fuel quality.
Â
2. By Installation Location:
• External Components:
Nozzles, hoses, boots, and breakaways—located on the outside of the dispenser, used directly by the customer.
• Internal Components:
Flow meters, filters, valves, pulleys, and structural brackets—housed within the dispenser body.
• Base and Mounting Parts:
Include foot plates, enclosures, seals, and frames that provide support and structural stability.
Â
3. By Material Type:
• Aluminum Alloy:
Lightweight, corrosion-resistant components for nozzles and housings.
• Stainless Steel:
Durable and suitable for harsh environments, used in valves, filters, and structural supports.
• Rubber and Composite Materials:
Used in hoses, seals, gaskets, and anti-static components for safety and flexibility.
Â
4. By Application Environment:
• Standard Fueling Stations:
General-purpose accessories designed for daily retail use with gasoline or diesel.
• High-Flow or Truck Stations:
Heavy-duty components such as large-diameter hoses and high-capacity nozzles for commercial vehicles.
• Cold or Harsh Climates:
Specially treated accessories with anti-freeze, anti-corrosion, or enhanced sealing features.
Â
All fuel dispenser mechanical accessories are manufactured to meet industry safety standards, ensuring long service life, operational accuracy, and compatibility with international fuel dispenser systems.
