QIHAI LASER Launches QH-6016GH 160mm Chuck 4000W Tube Laser Cutting Machine with Water-Assisted Slag Removal

Foshan, Guangdong, China - QIHAI LASER has launched the QH-6016GH, a 4000W tube laser cutting machine built for the 15-160mm pipe range that most fabrication shops work with every day. The machine combines a 6 metre loading bed, a 160mm chuck and semi-automatic loading with an optional water-assisted slag removal module that clears molten dross from the inside of the tube before it can bond to the bore wall.

The mid-range problem: dross you cannot reach

Fabricators cutting tube in the 60mm to 160mm range run into a specific difficulty. The outside of the cut is easy to clean with a grinder, but the inner wall is not. Molten dross thrown from the kerf cools and welds itself to the bore, and on tube longer than a metre there is no practical way to reach it. The consequence is visible at the next station: welding porosity, poor thread engagement, uneven coating adhesion, or a part that has to be scrapped after the cut was already correct.

The QH-6016GH addresses this with an optional water-assisted slag removal unit. A controlled water flow travels along the tube bore and meets the cut zone, quenching the molten dross and carrying it out of the tube before it solidifies on the inner surface. Water is recovered and recirculated through the chiller circuit, so running cost stays low in continuous shifts. The outcome is a clean bore, a dross-free lower cut edge and a part that moves to welding without manual reaming.

Machine configuration

What the specification means in production

• 4000W covers the everyday wall thickness range - carbon steel tube up to roughly 8mm wall and stainless tube up to 5mm are cut at production speed, which matches the majority of furniture, racking, gate and general fabrication work.
• 160mm chuck covers 15-160mm pipe - one machine handles the sizes a job shop actually quotes, instead of forcing a choice between an oversized platform and a machine that cannot take the larger jobs.
• Six metre bed keeps handling simple - standard 6m stock is loaded directly, and semi-automatic feeding shortens changeover between bars without the cost and floor space of a full automatic loading magazine.
• 80m/min positioning and +/-0.05mm accuracy - fast travel between features keeps hourly output high, while repeatable accuracy protects hole position and end-cut squareness on parts that are welded later.
• Optional bevel cutting - weld-ready end profiles can be produced on the same machine, reducing fit-up work at the welding station.

Five independently selectable functions

The QH-6016GH is supplied with five optional functions that can be specified separately according to tube size, wall thickness and downstream process: water-assisted slag removal, bevel cutting, zero tailing cutting, head removable around chuck, and weldseam identification. A buyer configuring a machine for furniture tube may choose water-assisted slag removal and zero tailing cutting, while a buyer producing structural components may prefer bevel cutting and weldseam identification. Nothing is forced into the base price.

Who the machine fits

The QH-6016GH is aimed at steel furniture and shelving producers, racking and storage system manufacturers, gate and fence fabricators, gym and fitness equipment makers and general job shops that cut mixed tube sizes daily. These are operations where the tube diameter rarely exceeds 160mm but where the bore cleanliness directly affects welding quality, and where a machine that is too large wastes capital while a machine that is too small limits the order book.

Availability and support

The QH-6016GH is available to order now with a minimum order quantity of one set. Machines are CE certified and carry a two year machine warranty, a laser source warranty of up to two years and a one year warranty on optional modules. Factory installation supervision, operator training and remote technical support are included. Fabricators can send sample tube for a cutting trial and receive a configuration proposal matched to their pipe sizes and downstream process.
