DW89CNC Mandrel Hollow Pipe Bending for Gym Equipment, Hydraulic Bending Tools, CNC Pipe Bending Machine.

The DW89CNC is a CNC-controlled, hydraulic mandrel pipe bending machine designed for bending hollow pipes used in gym equipment and other applications. It combines mandrel support with hydraulic power and CNC control for accurate, wrinkle-free bends.

Mandrel bending uses an internal support (mandrel) inserted into the hollow pipe during bending to prevent collapse, wrinkling or ovality — ideal for thin-walled or hollow sections such as tubing used in fitness equipment.

Yes. The machine uses a hydraulic system for bending force and a CNC control system for programmable, repeatable bending sequences.

The specification lists carbon pipe and stainless steel (S.S.) examples. Minimum bending radius is given as 1.5D with sample sizes shown (e.g., carbon pipe 115×6.0 and S.S. 88.9×3.0). It is intended for common hollow pipes used in auto parts, motorcycles, fitness equipment, bicycles, steel furniture and sanitary equipment. For other materials or specific diameters/wall-thickness combinations, confirm with the manufacturer.

Minimum bending radius is specified as 1.5D (1.5 times the tube diameter). Example entries in the spec include carbon pipe (115×6.0) and stainless steel (88.9×3.0).

Maximum bending radius listed is 300 mm. Maximum bending angle listed is 185°.

The availability (maximum) length of bending pipe is listed as 3500 mm.

Hydraulic oil pressure is specified at 14 MPa. Electrical motor power is specified as 11 kW.

Weight is listed as 3050 kg. Size is given as 4800 × 120 × 130 (units are likely millimetres as supplied in the specification). Confirm exact footprint and required clearance with the supplier before installation.

That line appears in the specification but is ambiguous. It may refer to an internal program count or a process code. Please confirm with the manufacturer or sales representative for the precise meaning.

The machine is recommended for auto parts (brake tubing, bumper, muffler, seat frames), motorcycle manufacturing, fitness equipment, air conditioning and refrigeration piping, bicycle industry, steel furniture and sanitary equipment manufacture.

Yes. Mandrel-type benders typically use interchangeable tooling (bending dies, mandrels, clamps, wipers). Specific tooling options and changeover procedures should be discussed with the supplier to match your pipe diameters and wall thicknesses.

Regular maintenance typically includes hydraulic oil checks and changes, filter replacement, lubrication of moving parts, periodic inspection of tooling and mandrels, and CNC/controller backups. For detailed schedules and spare parts, refer to the manufacturer's maintenance manual or contact their service team.

Installation, commissioning and operator training are commonly offered by the manufacturer or distributor. Spare parts and after-sales support availability vary by supplier—confirm lead times, warranty coverage and local service options when ordering.

The public specification lists key mechanical parameters, but exact figures for bending accuracy/repeatability, required power supply configuration, lead time, packaging, shipping and price are not provided. Contact the manufacturer or authorized dealer with your pipe sizes, material and production requirements to obtain detailed performance data and a formal quotation.
