DHKM Hydraulic Circular Cutting and Flanging Machine
The DHKM hydraulic circular cutting and flanging machine cuts a round blank from sheet and then flanges its edge, on the same head and in the same set-up. It works on flat discs and on dished (crowned) parts, such as the bottoms and lids of tanks and vessels.
Two models: the DHKM 6 for blanks up to Ø3850 mm and 6 mm mild steel, and the DHKM 8 for blanks up to Ø4550 mm and 8 mm mild steel.
• 2 models • Cutting up to Ø4550 mm • Flanging radius R10–R80 • 6–8 mm mild steel • LCD touchscreen

DHKM Design
The part sits on a carrier that moves towards the head and is adjusted up and down hydraulically. The blank turns while the cutting blades trim it to diameter. The flanging rolls then form the edge to the set radius.
- One head, two operations: cutting and flanging without moving the part to another machine.
- Roll drive: top and bottom flanging rolls are driven through planetary gearboxes, by an electric motor on the DHKM 6 and a hydraulic motor on the DHKM 8.
- Part carrier: double-speed, with hydraulic height adjustment for flat and dished parts.
- Support: side supports with hydraulic pistons.
- Control: LCD touchscreen operator panel.

Choosing the DHKM Hydraulic Circular Cutting and Flanging Machine
Choose the DHKM hydraulic circular cutting and flanging machine by the largest blank diameter, the sheet thickness and the flanging radius you need.
- DHKM 6: blanks up to Ø3850 mm, 6 mm mild steel or 4 mm stainless, radius up to R70.
- DHKM 8: blanks up to Ø4550 mm, 8 mm mild steel or 5 mm stainless, radius up to R80; hydraulic roll drive.
For thicker dished heads and flanging with or without a centre hole, see the DBFM flanging machine. To press the dish first, see the HPDP hydraulic dishing press. For thin sheet and rings up to Ø1000 mm, see the DKM circular shear.

Frequently Asked Questions About DHKM
What does a circular cutting and flanging machine do?
It cuts a round blank to diameter and forms a flange on its edge, in one set-up. The DHKM does both on the same head, on flat and dished parts.
Can the DHKM flange dished heads?
Yes. The hydraulic carrier adjusts its height for flat and dished parts. For thicker heads, with or without a centre hole, the DBFM flanging machine is the better fit.
Can it cut stainless steel?
Yes, up to 4 mm on the DHKM 6 and 5 mm on the DHKM 8. A special blade set for stainless steel is available.
What is the smallest diameter?
600 mm (DHKM 6) and 790 mm (DHKM 8) for cutting, or down to 400 / 620 mm with the small-diameter attachment.
DHKM or DKM?
The DKM cuts blanks and rings up to Ø1000 mm and 2 mm. The DHKM cuts much larger and thicker blanks and also flanges the edge.
