The ATK ball valve sphere machining machine is suited to small valve ball machining where buyers need a compact CNC solution for stainless steel valve balls. The technical catalog overview lists a 20-80 mm processable workpiece or pipe-diameter field, while the model table separately lists maximum bar diameters of 80 mm, 160 mm and 40 mm for ATK80, ATK130 and ATK40. These fields are not interchangeable and require model confirmation.

Source and specification boundary
Source basis: Technical catalog reference reviewed by AMY CNC on 2026-07-14. Catalog values are planning references and must be confirmed against the workpiece drawing and final quotation.
The technical catalog overview diameter and the model-specific maximum bar diameters are separate source fields. They are not interchangeable and require model confirmation before selection.
RFQ data buyers should prepare
- Workpiece drawings or photos with target dimensions.
- Valve type, valve size, material, and machining sequence.
- Required tolerance, surface finish, cycle target, and batch quantity.
- Voltage, available floor space, loading method, and automation preference.
- Any fixture, coolant, safety, packing, or local service requirement.
Buyer questions
What should buyers confirm before selecting the ATK Ball Valve Sphere Machining Machine?
Confirm the workpiece drawing, valve size range, material, required accuracy, production rhythm, voltage, fixture requirement, and whether any automation or loading option is needed.
Which valve parts does this sphere machining machine support?
The catalog evidence supports small stainless steel valve balls and ball-valve components. Final scope should be checked against the buyer’s drawings and target machining sequence before quotation.
Can AMY CNC prepare OEM documentation and nameplate requirements?
Discuss nameplate and documentation requirements with our factory before quotation. Record the agreed configuration, service scope and any required compliance documents in the order.
How should buyers use the specification table?
Use the specification table to compare model size, workpiece range and utilities. Confirm the selected model, fixture, tooling, accuracy and acceptance criteria against your drawing before ordering.
Next step
Send the workpiece drawing, target production rhythm, material, voltage, and preferred loading method. AMY CNC can map the requirement to a suitable machine family and prepare a technical quotation proposal.
