JFY – VR Series CNC Shearing Machine

Short intro, no fanfare. JFY has been around for 25 years, pumping out sheet-metal gear from their Jiangsu plant, roughly 40 000 square meters of weld fumes and coffee mugs. The VR family, insiders still call it “the green rake” because the first demo units left a jade paint trace on every trade-fair floor, has rolled through three major revisions. Each tweak, from hydraulic manifold casting to touchscreen PCB, came out of forums, field notes, the occasional irate email from a Dubai job shop that tried to run 10 mm stainless in August heat.

Cutting physics

Stop, think. Guillo­tine shearing is simple, blade goes down, metal gives up. Yet, the evil is in the angle. Variable rake lets you push thicker plate without cranking pump pressure into the red. VR handles a span from 0.5° to 2°. Mild steel up to 13 mm, stainless a hair less, aluminum walks in the park. Rake change is servo-driven, the controller needs roughly 2 seconds to hop from minimum to maximum.

Before diving deep, two quick bullets to clear the air, then we move on.

• Blade gap chart pops up automatically on the CNC, so the night shift cannot mess it up.
• Backgauge uses a ball-screw, not a chain, so repeatability stays inside ±0.05 mm even when the workshop AC dies.

Cool. Continue.

Core parameters

The numbers below are pulled from JFY’s own English manual revision 2023-11 and cross-checked against three UAE installers who signed off final acceptance reports.

Stare at the table, sip coffee, then notice what hides between the lines. The stroke count is not fixed, the inverter talks to the hydraulic valves, so thin sheet climbs to 12 cuts every minute, thick slab drops to 8 to save the blades.

After the table, let us scratch the surface of everyday usability.

Operator view

You walk up, LCD is already awake because the previous guy never hits shutdown. Interface icons look cheaper than on a smartphone, but the order of menus makes sense. Blade life counter ticks in hours, not strokes, which at first feels weird yet mirrors reality, thicker runs age the edge faster. Two USB slots, one on the panel front, one behind the door, shielded from coolant mist. UAE shops love to keep the G-code on thumb drives, network cables gather dust.

There is a foot pedal, standard, but JFY finally learned to fit a silent return spring. Less clanging. Safety light curtain is optional. Most Gulf clients pick it because insurance inspectors are picky after 2021 overhaul of federal regulations.

Heat tolerance

Dubai summer, 45 °C plus humidity from the creek, kills hydraulic seals faster than bad coffee. VR units leaving the factory for the Middle East carry Viton O-rings and a bigger chiller loop. Oil stays under 55 °C even during double shift. Field notes from Sharjah confirm this, pump housing measured 51 °C after continuous 7 hour run on 8 mm carbon steel.

Maintenance corner

Need a break, so here is a quick list for the foreman’s fridge magnet.

• Flip blades every 450 hours, four-way edge pattern saves money.
• Change oil at 2000 hours or once a year, whichever bites first.
• Backgauge belt tension check every Monday, tool-free, just lift the hatch.

Do those and the machine keeps its temper. Skip them, and the backgauge starts singing off-key.

Series lineup

Same VR tag, different muscle. Three mainstream sizes ship to the Gulf right now.

• VR-31010, 3100 mm length, 10 mm thick, fits containers easier.
• VR-41013, the one we dissect here, sweet spot for HVAC shops.
• VR-61016, 6100 mm length, 16 mm thick, mainly for shipyards in Abu Dhabi.

Frame geometry stays identical, only table length and cylinder bore change. So operator training is a one-time pain.

Market comparison

Enough brand brochure talk, how does VR stack up against usual suspects from the same aisle.

The Turkish Durma wins on raw horsepower yet drinks more amps, which can be a headache with DEWA tariffs. Accurl matches many points yet charges extra for the heat exchanger that JFY throws in by default.

Real shop feedback

One Sharjah subcontractor cutting 6 truckloads of mild steel weekly told me, over WhatsApp voice note full of machine noise, that the VR backgauge homed within 0.03 mm after a forklift bump. Another, a small Ras Al Khaimah fab shop, swapped the OEM blades for Bohler after 18 months, not because of chips but they just wanted longer edge life on 304 stainless. Their words, not marketing.

Control options

The stock E21S controller suits 80 % of tasks. If you feel posh, pay extra for the DAC-360T touch panel. Net gain is graphics for multiple cut lists and angle presets. Firmware already contains Arabic dialogs, though the translation feels Google-ish. You can always fall back to English.

Installation footprint

Floor space, including the service corridor, lands at 5300 × 2550 mm. Weight is about 14.5 t. A regular 20 t overhead crane does the trick. Anchor bolts, M24, 12 of them, dry in 48 hours. JFY manual pretends you have epoxy anchors, in real life most shops just chemical stud them and call it a day.

Operating cost

Crunch quick math. Power draw hovers around 18 kW under load, roughly 0.08 dirham per kilogram of mild steel sheared if your DEWA rate is 0.32 AED per kWh. Blades are 620 AED each edge when you buy four-way sets, so budget 0.02 AED per kilogram on consumables. Not bank breaking.

Spare parts flow

TRUMPF-JFY joint venture means many hydraulic blocks are sourced through Bosch-Rexroth. That cuts lead time, because Dubai has a Rexroth warehouse. Electrical parts sit on Siemens shelf, easily next-day from Jebel Ali free zone.

Final takeaway

The VR family does not claim magic, it just chops metal, day in day out. Variable rake, reasonable stroke speed, chilled oil tank, all wrapped in a frame thick enough to survive desert logistics. That combo explains why you see these machines in HVAC duct lines, trailer chassis plants, and an odd art sculpture studio that loves beating up 5 mm Corten.

Key advantages

• Variable rake lets you attack thick plate without oversizing hydraulics.
• Standard oil cooler keeps seals alive in Gulf summers.
• CNC backgauge with 1000 mm travel crushes rework and aligns with lean layout.

And that is it, blades down, job done.
