JHMX-303 Series 3-in-1 Busbar Machine
Punch · Shear · Bend in one frame · 12 × 160 mm · four models from essential CNC to full servo positioning
JHMX-303 Series 3-in-1 Busbar Machine
Three machines in the footprint of one — and four control levels to grow with your shop, from essential CNC to full servo positioning.
Pick the Control Level You Need
All four models share the same punch / shear / bend platform and the 12 × 160 mm processing range. The difference is how the workpiece is positioned and how precise the bending is.
JHMX-303-SK-02
Siemens PLC bending — input thickness and angle, the machine computes the stroke. Punch and shear positioned on the 1,000 mm stop gauge.
JHMX-303-SK-01
Adds servo X/Y positioning for punching and servo-controlled bending, with job memory that recalls previous workpieces instantly.
JHMX-SF303-SK-02
Servo positioning modules and a 3.7 kW servo bending drive — bending positioning accuracy of ±0.02–0.04 mm for tight-tolerance work.
JHMX-SF303-SK-03-200K
The SF303 precision servo platform in the extended 200K configuration — built for heavier duty cycles and volume production.

One Frame, Three Independent Stations
Punching Station
300 kN punch with quick-change dies Ø 4.3–34 mm on a six-station ductile-iron turret. Eight die cores ship standard; change a die in under a minute.
Bending Station
CNC flat and edge bending — input thickness and angle, the Siemens PLC computes the stroke. Closed-frame design keeps angles repeatable, batch after batch.
Cutting Station
Double-column shear for square, burr-free cuts up to 12 × 160 mm. 1,000 mm cut-to-length stop gauge included.

JHMX-303 Series — Common Questions
Which of the four models should I choose?
If you position bars by hand today, the SK-02 is the value pick. Choose the SK-01 when you punch many hole patterns and want servo X/Y positioning with job memory. Choose an SF303 model when bending tolerance is critical — its servo drive holds ±0.02–0.04 mm positioning accuracy. Send us your bar sizes and we will confirm the best fit.
Can the three stations really work at the same time?
Yes. Each station has an independent motor, pump and valve block, so punching, bending and cutting can run simultaneously — a key reason the JHMX-303 outsells single-station machines.
What is the delivery time?
Standard machines ship in 10–15 working days after payment. It is our fastest-shipping model.
Is the JHMX-303 suitable as a first machine for a small shop?
Absolutely — every model covers punching, bending and cutting for bars up to 12 × 160 mm. Many customers start with the SK-02 and move up to servo positioning as volume grows, keeping the same tooling.
What training and after-sales support do you provide?
Remote installation guidance and operator training by video call are included. Spare parts ship from stock within 48 hours; technical response within 24 hours.
Can you customize voltage and plugs for my country?
Yes — 220/380/415/440 V at 50 or 60 Hz, with the plug type matched to your local standard.
