Robust Construction and Precision EngineeringThe WMW Heckert ZFWVG 250 x 2000 mm Thread Milling Machine features a heavy-duty cast iron body and hardened, ground slideways, ensuring excellent vibration dampening and longevity. Designed for high-precision thread, spline, and gear cutting, it supports up to 2000 mm long workpieces with a maximum thread diameter of 250 mm. The robust tailstock and adjustable table improve machining stability during intensive operations.
Versatile Threading and Milling CapabilitiesEquipped with both a hobbing head and milling head, the machine allows users to perform a diverse range of operations, including threading, spline cutting, and gear manufacturing. The wide thread pitch range (0.5-100 mm) and feed options (manual and automatic from 0.02 to 6 mm/rev) offer remarkable flexibility. It is adaptable to both 3-jaw and 4-jaw chucks, facilitating straightforward workpiece changes.
Reliable and Efficient OperationDelivering spindle speeds from 22.5 up to 1120 rpm and driven by a powerful 7.5 kW main motor, the ZFWVG 250 x 2000 operates efficiently in demanding environments. Its integrated coolant system supports longer tool life and consistent machining results. The manual control system ensures operational simplicity for skilled technicians, making it ideal for both export and domestic manufacturing.
FAQ's of WMW Heckert ZFWVG 250 x 2000 mm Thread Milling Machine:
Q: How does the WMW Heckert ZFWVG 250 x 2000 ensure precise thread cutting?
A: The machine is engineered with hardened and ground slideways for stable, vibration-free movement. Its manual controls and flexible feed options allow for fine adjustments, while the included hobbing head and milling head provide high accuracy when cutting threads, splines, and gears.
Q: What is the maximum size of workpieces that can be machined?
A: This model can accommodate workpieces up to 2000 mm in length and a maximum thread cutting diameter of 250 mm. The distance between centers and over-bed diameter ensures large or complex workpieces can be handled with ease.
Q: When is it appropriate to use the hobbing and milling heads included with the machine?
A: The hobbing head is ideal for cutting gears and certain types of splines, while the milling head is preferred for more general-purpose milling or threading applications. Operators switch between the heads to match the operation required by the job specification.
Q: Where can the WMW Heckert ZFWVG 250 x 2000 be installed safely?
A: Due to its substantial size and weight (approx. 7500 kg), it should be installed on a solid shop floor with sufficient space-about 5200 x 1800 mm-for both operation and maintenance. Proper electrical connections for 3-phase, 415V, 50Hz power are also necessary.
Q: What accessories are provided with this thread milling machine?
A: The machine is supplied with a hobbing head, a milling head, change gears, centers, standard tooling, and an integrated coolant system, making it well-equipped for a wide range of threading and milling tasks.
Q: How is the machine operated without CNC or computerized controls?
A: Operation is entirely manual, handled via control levers and dials. This simplifies maintenance and allows experienced machinists to make precise adjustments in real time, which can be preferred in specific manufacturing contexts.
Q: What are the main benefits of using this thread milling machine?
A: Key benefits include its ability to handle heavy-duty workpieces, support versatile threading and milling processes, and maintain reliability over long-term use thanks to robust construction and quality components. Its flexibility and heavy-duty accessories make it an excellent choice for industrial manufacturing.
