Hydraulic multi-station fixture for CNC machining centres

Name: Hydraulic multi-station fixture for CNC machining centres
Brand: Dongben Workholding
SKU: DB-FIX-CUSTOM-01
Availability: InStock

Built to your drawing: one set-up, several parts per cycle, repeatable to 0.01 mm.

Hydraulic clampingMulti-stationBuilt to drawing0.01 mm location

A dedicated hydraulic fixture designed around the part, not around a catalogue. We take your 3D model, the machine table drawing and the tolerance stack, then design the locating scheme, the clamp sequence and the hydraulic circuit so that the part is machined in one set-up with no re-clamping between operations.

Typical use: aluminium or cast-iron housings, covers, brackets, bearing carriers and valve bodies in batch sizes from 200 to 50,000 pieces per year, where cycle time and repeatability both matter.

Clamping elements	Swivel clamps, swing clamps, wedge clamps, support cylinders
Hydraulic unit	Optional power pack: 1.5–7.5 kW, air-hydraulic or electric
Control	Manual valve panel, or interface to machine M-code
Machine interface	T-slots, zero-point grid or sub-plate, per your table drawing

How it is built

Design review before metal is cut

We return a DFM note within 3 working days: datum choice, clamping force, wall thickness risk, chip evacuation and clearance to the tool holder. Nothing is machined until you sign the design.

Prove-out before shipment

Every fixture is assembled, pressure-tested at 1.5× working pressure and run through a trial cut. You receive the trial-cut video, the CMM report and the hydraulic schematic.

Spares that fit

Clamping elements, seals and locating pins are standard catalogue items, so a worn clamp is a next-day replacement rather than a new fixture.

Questions

What do you need to quote a hydraulic fixture?

A 3D model of the part (STEP or X_T), the machine table drawing, the operations to be performed, the required cycle time and the annual volume. A 2D drawing with the tolerance stack is enough for an indicative price.

How is the fixture located on the machine?

Three options: T-slot keys, a zero-point sub-plate, or a dedicated base plate bolted through existing holes. We match whatever is already on your table so you do not buy a new pallet system.

Who owns the design?

You do. The 3D model, drawings and the hydraulic schematic are delivered with the fixture and are yours to use, modify or re-order against.

What is the usual lead time for a repeat order?

3–4 weeks for a repeat of an existing design, because the drawings and the proving programme already exist.
