三. Utility, Installation & Commissioning

Q6: What utility conditions are required for SY‑830B Automatic Gantry Cutting Machine?

A6:Power supply: 3‑phase 220V /50 Hz, reliable protective earthing mandatory. External compressed‑air supply required, stable pressure 0.6 MPa. Floor load‑bearing ≥3400 kg. Check doorway & aisle dimension before delivery due to long machine body. Keep workshop ventilated; keep hydraulic oil away from open fire. Reserve ample space for head cross‑travel, platform movement, die disassembly‑assembly and maintenance. Extension: Machine overall length exceeds 5 m, verify factory passage in advance. Hydraulic oil is flammable; basic fire‑fighting equipment shall be equipped.

Q7:What are requirements for installation & placement of SY‑830B Automatic Gantry Cutting Machine?

A7:Place machine on flat hard load‑bearing floor and level whole unit. Do not stack materials on both sides of gantry‑head travel path to avoid mechanical interference. No obstacles above worktable. Keep away from high‑temperature heat‑source and open fire. Reserve clearance for electric, hydraulic and servo‑guide‑rail maintenance.
Extension: Do not install tight against wall. Keep safety clearance on both sides for traveling‑head stroke.

Q8:What is complete test‑running operating procedure for SY‑830B Automatic Gantry Cutting Machine?

A8:

1.Confirm reliable power earthing. Connect compressed‑air source and confirm stable 0.6 MPa pressure. Fill 80 kg hydraulic oil; verify oil‑pump rotation direction; level whole machine.

2.Switch to 【Manual Mode】, mount die. Use black hand‑wheel plus setting‑switch with 4 mm EVA sheet for die‑height calibration. Extension: Never place hands under cutting‑head during die‑setting.

3.Perform trial cut under manual mode. Increase cutting‑depth parameter by 5 ms per step, do not make large‑step adjustment in one time. Confirm full penetration of trial sample.

4.Move head & feeding‑platform manually, finish 【initial cutting‑position calibration】. Set knives‑per‑row, moving distance, feed‑length, dwell‑hold‑time on touch‑screen; select nesting mode Mode1/2/3; save as recipe.

5.Switch to 【Auto Mode】, home‑reset machine, load raw‑material and start automatic production. Machine stops immediately once safety light‑curtain is blocked.

⚠️Important: Do NOT modify recipe parameters while machine runs automatically. After X/Y‑offset modification: trigger emergency‑stop to clear system memory and re‑home origin point. 6.After production: execute full‑machine home‑reset, stop oil‑pump motor and cut‑off main power. 7.Maintenance procedure: power‑off; wait hydraulic‑system full cooling; place solid support block between cutting‑head and platform before repair work.

Q9: What precautions for recipe‑management & nesting‑mode selection?

A9:Mode1: regular neat‑array for standard nesting. Mode2: dislocation with reduced knives on alternate rows. Mode3: dislocation with equal knives per row. Always save recipe after parameter modification for later recall. Old‑recipe parameters cannot be reused directly after die‑change or material‑thickness change; re‑trial‑cut and re‑calibration is mandatory.
Extension: Die dimension shall not exceed moving‑head dimension 350×350 mm, otherwise mechanical collision will occur.
