Features and performance of the LEO 1600 series. The LEO 1600 series from DN Solutions is a compact, high-speed horizontal turning center (using a 6-inch chuck), designed to deliver outstanding machining productivity for round, circular workpieces,. Below is detailed information regarding the features and performance of this machine series:
1️⃣ Basic Structure and Machining Area (Optimized Design) - Stable structure: The machine utilizes a 30° slanted stable bed structure combined with a highly rigid roller-type LM guideway system on all axes, ensuring stability and reliability during the machining process,. - The largest machining area in its class: Despite its highly compact design (with a machine width of only 1850 mm), the LEO 1600 offers an extremely spacious machining area,:
Dimensions: 1850 mm x 1690 mm. X-axis stroke (travel distance): 175 mm. Z-axis stroke (travel distance): 330 mm.
Robust construction - Large processing area
- Machining Capacity: The maximum turning diameter reaches 320 mm - 332 mm, and the maximum turning length is up to 303 mm,. The machine allows a bar working diameter of 45 mm and supports a maximum allowable workpiece weight (including the chuck) of up to 70 kg for chuck work and 150 kg for shaft work.
2️⃣ Powerful Cutting Performance - Spindle: The machine is equipped with a highly reliable spindle featuring high-rigidity bearings, reaching a maximum spindle speed of 4000 r/min,,. The main spindle motor power is 7.5/5.5 kW, generating a maximum spindle torque of approximately 71.6 - 72 N·m, which perfectly meets flexible cutting requirements. - Turret: Equipped with a high-strength octagonal turret (durable 8-station design) that ensures stable tool rotation and supports up to 12 tool positions (stations),,. This facilitates fast and stable tool selection, maintaining powerful performance during heavy cutting,. The turret indexing time (1 station swivel) takes only 0.15 seconds. - Tailstock (Optional): Customers can optionally equip a rigid tailstock to provide stable support when machining long workpieces (quill diameter 65 mm, quill travel 80 mm). The rapid traverse rate of the X and Z axes goes up to 30 m/min, significantly reducing non-cutting time
3️⃣ Energy Saving Efficiency (ESG / Energy Certificate) The LEO 1600 machine holds an Energy Certificate thanks to improvements that help save 10.52% in power consumption compared to previous models (a reduction of approximately 157.526 kWh/month). This energy saving comes from: - High-efficiency 3-phase motors (Class IE3/IE4) and a high-efficiency LED work light & signal tower that consume less power. - Low power solenoid valves, and the latest low-loss servo & spindle amplifiers with low power dissipation. - Power saving function to reduce standby power and an optimized electrical cabinet cooling system.
4️⃣ Ease of Operation and Support Features - User-friendly design: The front window is reclined/angled for easy monitoring by the operator, and the wide door opening of 430 mm helps reduce operator workload. Chip disposal is directed to the rear side, and routine maintenance details are conveniently placed at the front of the machine. - DN Solutions Fanuc i Plus smart controller: Equipped with a 10.4-inch display featuring an intuitive and user-friendly design. Notably, it integrates the Sketch-Turn conversational programming software for PC, which is easy for beginners to learn, saves programming time, and reduces processing cycle time. In addition, the EZ Work function allows for easy tool management, machining load monitoring, and peripheral device settings. - Flexible peripheral equipment options: The machine supports various options to optimize automation, such as: Chip conveyor, Part catcher, Tool setter, Oil skimmer, Dust collector, and Quick change CAPTO tooling system. High pressure coolant pump: Upgrade from the standard pump (1.3 bar) to a 1.5 bar or 4.5 bar type and Coolant Chiller to minimize thermal deformation.
5️⃣Machined Materials The LEO 1600 is commonly used for machining popular metal materials, specifically: - Steel and Cast steel: This is clearly reflected in the machine's chip conveyor options. The hinged belt conveyor is specifically designed for steel applications (producing 30mm chips or longer), while the magnetic scrapper conveyor is recommended for cast steel machining applications. - Flammable materials: The documents provide a specific safety warning about the high risk of fire when processing "flammable materials" if non-water-soluble cutting fluids are used or if coolants are not controlled properly.
6️⃣Machined Products (Workpieces) The LEO 1600 is a compact, high-speed horizontal turning center optimized for machining round, circular workpieces. The characteristics of the products this machine can process include: - Flexible dimensions: The machine can turn products with a maximum turning diameter of up to 332 mm and a maximum turning length of 303 mm. - Long shaft-type products: With the support of the rigid tailstock, the machine ensures stable support when machining long shaft-shaped workpieces. - Heavy products: The machine has excellent load capacity, allowing a maximum allowable workpiece weight of up to 70 kg for chuck work and 150 kg for shaft work. - Mass production from bar stock: The machine allows a bar working diameter of up to 45 mm. When combined with options like the bar feeder interface and the part catcher, the machine is highly ideal for the mass production of small and medium-sized parts
7️⃣ Practical Industrial Applications
DN Solutions' turning and machining solutions—including the LEO 1600—are widely deployed across key industrial sectors, including: - Automotive, Aerospace, Energy, Medical Devices, Semiconductors, and Die & Mold Manufacturing. - Typical End Products: Automotive spare parts and components, lock nuts, cutting tools, and fasteners. Summary: The LEO 1600 is a compact horizontal turning center that delivers the power and capability of larger machines. Combining high speed, precision, and energy efficiency, it is an ideal solution for optimizing productivity and shop-floor space utilization.
