Frequently Asked Questions (FAQ):

What is the maximum weight of a workpiece this machine can handle?
The machine is designed for heavy-duty applications. The standard configuration can typically handle workpieces up to 20 tons, but this is fully customizable based on your specific requirements for even larger frames.
Can it machine materials other than cast iron?
Absolutely. While optimized for heavy cast iron, the machine's powerful spindle and rigid structure are equally capable of milling various steels, alloys, and other hard metals used in heavy equipment manufacturing.
How customizable are the machine's travel distances and table size?
Extremely customizable. The X, Y, and Z axis travels, as well as the worktable dimensions and load capacity, are key parameters we tailor to match your largest frame components and production workflow.
What kind of precision and surface finish can I expect?
Utilizing precision components and advanced control systems, the machine delivers high positioning accuracy and repeatability. For cast iron frames, it can achieve surface finishes suitable for functional mating surfaces without extensive secondary processing.
What after-sales support and training do you provide?
We provide comprehensive installation guidance, operator training, and technical support. A detailed manual and access to our engineering team ensure smooth integration into your production line.
Is the CNC control system user-friendly for our operators?
Yes. We offer industry-standard control systems from brands like Siemens or Fanuc, known for their intuitive programming interfaces and widespread use, which helps reduce the operator learning curve.
What are the power requirements for this large machine?
Being a heavy-duty machine, it requires a substantial power supply, typically in the range of 80-150 kVA depending on the spindle configuration. Specific requirements will be detailed in the customized proposal.
How do you ensure machine quality and reliability?
Our manufacturing process adheres to strict quality standards, including ISO 9001. Each machine undergoes rigorous factory testing and run-off procedures before shipment to verify performance against agreed specifications.
