Grinding of inner diameters of sleeves
We provide services for internal grinding. We work with large diameters.
We grind the inner surfaces of pipes and sleeves on a special lathe.
We grind the inner diameter from 220 mm, the outer diameter up to 1000 mm.
Other sizes on request (it is possible to modify or create a project-specific stationary or mobile equipment for grinding).
We use internal grinding to restore the sleeves of large hydraulic cylinders.
We also provide services for grinding shafts and rollers with mobile machines.
Our advantages
Specialized machine park for grinding large inner diameters
We have a large park of stationary equipment: turning, jig boring, milling, jig drilling, hydraulic section
We have mobile machines for boring, grinding and milling on site
We work with non-standard orders. We have our own design department for developing design documentation and technology for complex repairs and an R&D department for designing and developing new equipment and machines for the project.
We also provide forging blanks and CNC precision machining services for our clients, covering industries such as energy, petrochemicals, steel, engineering machinery, plastics, prevention and control, hydraulics, healthcare, and food. Please feel free to send us drawings for inquiries.

Heavy Forging Press Capacity
Our heavy-duty forging presses support open-die forging and deformation of large-section forgings, including discs, shafts, blocks, and custom components. This capability enables us to meet the demanding forming requirements of heavy industrial applications.
Heat Treatment Capability
Heat treatment is a critical step in achieving the mechanical properties required for heavy-duty forgings. Our process capabilities meet the strength, toughness, and structural stability requirements for forged components used under demanding operating conditions.
Heavy Shaft Machining
We offer machining capabilities for large forged shafts and long cylindrical components, supporting both rough and finish machining. This capacity is suitable for stepped shafts, rotor shafts, rollers, and other heavy-duty forged shaft components.
Ring Forging Machining
Our machining facilities are capable of handling large ring-shaped forgings and circular parts that require precise turning, face machining, boring, and contour control. This capability is suitable for industrial ring blanks, heavy-duty circular parts, and machined ring forgings.
Cylindrical Forging Machining
We offer machining solutions for heavy-duty cylindrical, hollow, and tubular forgings. This capability supports the machining of sleeves, cylinders, and other thick-walled forged components used in pressure vessels, rotating systems, and general industrial applications.
Inspection & Testing
Quality control is integrated into our production process through the inspection and testing of forged and machined parts. Our capabilities help verify the dimensional accuracy, condition, and quality consistency of industrial forgings prior to delivery.
Packing & Delivery
Finished forgings are properly protected and packaged to minimize the risk of damage during storage and transportation. Our packaging methods ensure the safe domestic delivery and export shipment of machined and high-value forged components.
