Condition: like new (used), Year of construction: 2019, operating hours: 3,000 h, functionality: fully functional, LIEBHERR LK 200 – CNC Gear Skiving Machine Main technical data CNC control: Siemens HMI (Liebherr LHStation / LHMobile operator concept) Max. module: approx. 3.0 mm Max. workpiece diameter: approx. 200 mm Max. workpiece weight: approx. 25 kg Table diameter: approx. 285 mm Axial travel: Axial stroke up to approx. 500 mm Machining stroke / shift distance: approx. 400 mm Max. spindle power: 16 kW Max. workpiece spindle speed: 3,000 min⁻¹ Max. feed rate (radial): 7,500 mm/min Hob / tool speed: up to 4,000 min⁻¹ Max. tool diameter: approx. 150 mm Wet machining Especially for internal gears, wet machining offers major advantages: During the skiving process the cutting edges are cooled and lubricated, which significantly reduces the thermal load on the tools. The chips produced are reliably removed and are not drawn back into the cutting zone. Optimal chip evacuation leads to improved gear accuracy and superior surface quality. LHStation & LHMobile operator concept Liebherr intelligently separates programming and machine operation into two units: LHStation (fixed operator panel / monitor): Large screen area for data input and process monitoring Multi-touch surface with additional tactile elements Increased operating speed and process reliability LHMobile (mobile handheld unit): 10" multi-touch as standard Context-sensitive views such as PLC/NC keys, program status and messages Wired signal transmission for maximum safety during setup Kjdpexwzvlsfx Aadedw Ideal for ergonomic, user-friendly operation directly at the machine Skiving³ – overview of advantages Machine Very rigid machine design with cast-iron bed to absorb process forces Ringloader concept for fast workpiece change Tailstock for shaft machining and optimum workpiece clamping Optional chamfering during the machining process Burst-proof enclosure, suitable for both dry and wet machining (oil or emulsion) Tool Design and manufacture of conical and cylindrical skiving cutters Process-optimized tool design for every workpiece Tools available in PM-HSS and solid carbide versions Process Comprehensive process analysis and simulation to determine optimum cutting conditions Use of technology applications for customized process optimization Collision analysis with calculation software to secure the process Machine concept – efficiency through gear skiving Gear manufacturers are looking for alternatives that are: More productive and cost-effective than gear shaping At the same time more flexible than broaching The LK 200 is designed exactly for this: The basis is the high rigidity of the machine bed and skiving head (special bearing concepts, also for longer tool holders – crucial for internal gears). Combined with a burst-proof housing, the machine is suitable for both dry and wet cutting. The integrated tailstock unit makes the system universally usable for: External and internal gears Shafts and short gears on one machine By combining machine, tool and process (Skiving³), the LK 200 offers a fully integrated solution for highly productive gear skiving.

Sustainable Reliability: Ensure reliable and sustainable processing. Cost Efficiency & High Productivity: Benefit from lower production costs and high productivity due to a short grinding process and reduced production times for subsequent processes (cylindrical grinding). Quirlig Grinding Technique: Experience an optimized grinding process with the Quirlig Grinding Technique. Properly ground center holes that have cross-hatched grinding pattern. The cross-hatched grinding pattern ensures that oil is retained when the workpiece is placed between the centers during the cylindrical grinding process, creating a micro oil layer. The micro oil layer prevents unwanted "dry running" during cylindrical grinding. Easy to Use CNC Control Panel: Benefit from very simple operation and grinding program recording with the Beckhoff control panel and Z-axis servo movement. Industry 4.0: Fully compatible with Industry 4.0 applications, thanks to the Beckhoff control panel. Low Maintenance Costs: Enjoy low maintenance costs throughout the machine's service life, thanks to Swiss-quality construction. The Zentroflex SA-series center hole grinding machines are designed to deliver high-precision cylindrical grinding in the aviation, automotive, and machinery sectors. Additionally, the Zentroflex SA-series is the ideal solution for recovering parts distorted after heat treatment or for reducing cylindrical grinding costs. Z-Axis movement is provided by servo motor in CNC form. The part is loaded-unloaded and clamped manually. Settings are made from CNC control panel and grinding is started by pressing the start button. No other manual setting or control is made during grinding. Contact us for more details.
