Vertical Lathe Machining – Process for Large Components up to 25 t
In vertical lathe machining, the workpiece rotates on a horizontal table while the cutting tool traverses vertically and horizontally. This makes the process suitable for large, heavy components that are too big for conventional lathes. The Ø 4,800 mm table offers a turning height of up to 2,400 mm. When boring, the drilling head engages from above and limits the usable height to 2,000 mm drilling height. The height actually achievable depends on how the workpiece is clamped and supported – we are glad to advise on a project-specific basis.
Flanges, rings, bushings and disc-shaped parts are manufactured to drawing. CNC control ensures reproducible tolerances, even on heavy and large-format workpieces. The 2×25-t crane system in the plant allows safe set-up and positioning.
Individual parts, small batches and recurring series parts are manufactured in Lorch on a contract basis – no minimum order quantities, with reliable delivery to the agreed schedule.
Dimensional inspection is carried out to drawing and tolerance specification with calibrated measuring equipment. Dimensional reports are prepared on a project basis and included in the scope of supply. Material certificates for the materials used are available on request. Quality assurance follows DIN EN ISO 9001:2015 with full traceability.
At Bock, vertical-turned parts are often used as a pre-fabrication stage for complex welded structures and special-machine components. Because turning, milling and welding work directly together in the same facility, components can be passed on without external logistics – significantly shortening lead times.
Heavy turned parts for crane and lifting-gear structures, vehicle systems and plant engineering are manufactured regularly at Bock. The 2×25-t crane system in the plant ensures reliable, safe handling and set-up of heavy parts up to 50 t – even with unwieldy dimensions.

Materials for CNC Turning and Vertical Lathe
Bock uses predominantly European-certified quality steels with full material traceability:
- Structural steel S235, S355 – Standard structural steel
- Fine-grained structural steel up to S1100 – high-strength, weldable
- Hardox 400 / 500 – wear-resistant steel for high-stress components
- Stainless steel 1.4301, 1.4571 – corrosion-resistant
- Special steels to drawing and customer specification
Material certificates and test reports are provided on request or according to project requirements.
Typical Applications
Vertical lathe machining at Bock is used for large and heavy rotational components manufactured to drawing or specification:
- Flanges for pipelines, pressure vessels and plant engineering
- Bushings, hollow cylinders and rings for special machinery
- Large rings and disc parts for heavy-duty applications
- Mounting plates and base plates for machine foundations
- Turned components for vehicle and crane systems
Turned components are frequently used as a pre-machining stage for welded assemblies and heavy steel fabrications. Production and quality documentation to DIN EN ISO 9001:2015 is available as standard for all order types.

Frequently asked questions about vertical turning
What is vertical turning?
In vertical turning, the workpiece rotates on a horizontal turntable while the tool traverses vertically and horizontally – for rotationally symmetric components that are too large and too heavy for conventional lathes. For this, Bock uses the Feichter FKD30/20 CNC vertical lathe in contract manufacturing in Lorch, from single parts to series.
Up to what diameter, what height and what weight is vertical turning carried out?
The vertical lathe turns up to Ø 4,800 mm turning diameter and 2,400 mm turning height; the workpiece weight is limited by the table load to 25 t. When drilling, the drilling head feeds from above and limits the usable height to 2,000 mm drilling height; the component height achievable in practice depends on how the workpiece is clamped and supported.
Are smaller turned parts also produced on conventional lathes?
Yes. In addition to the vertical lathe, two conventional lathes are available: a TOS SUS 63H with Ø 655 mm turning diameter and 2,000 mm turning length, and a Meuser with Ø 350 mm turning diameter and 1,000 mm turning length.
Can welded structures be turned on the vertical lathe?
Yes. Large rings of welded construction are turned bright at the ring face on the vertical lathe; turning, milling and welding take place in the same company.
Is a dimensional report supplied with vertical-turned parts?
Yes, on a project basis. Dimensional inspection is carried out to drawing and tolerance specification with calibrated measuring equipment, and the dimensional report is included in the scope of supply; material certificates for the materials used are available on request.
