GL-645 planing moulder 450mm Width

Gau Jing
For timber frame builders, sawmills, and structural joinery shops that regularly handle sections wider than standard 4-sided planers can manage — the GL-645 brings 450 mm capacity, configurable spindle count, and high feed speeds into a single heavy-duty machine.

Typically chosen by

  • Timber frame and structural joinery businesses processing beams, posts, and pillars that exceed the capacity of standard 4-sided planers
  • Sawmills and large joinery manufacturers needing high-throughput wide-board surfacing and profiling in a single pass
  • Workshops tendering for construction or fit-out contracts that regularly specify wide moulded sections and cannot afford repeated re-runs through narrower machines

Key specification considerations

Maximum Working Width
450 mm
This is the practical upper limit for a single pass — confirm your widest regular section against this figure, allowing a small margin for material variance.
Number of Spindles
4 to 8 (configurable)
More spindles allow additional profiling operations in a single pass, reducing the need for secondary machining runs and improving surface finish at speed.
Feed Speed
6–120 m/min (configurable)
The upper range suits high-volume straight planing; lower speeds are typically selected when running complex profiles or harder timbers where surface quality matters more than throughput.
Feed Roller Width
450 mm with hydraulic outboard bearing support
Hydraulic outboard bearings help maintain consistent downward pressure across the full roller width, which is particularly important when processing wide or uneven sections to prevent chatter marks.

Optional Jointer Devices
Straight knife jointer and profile knife jointer
Knife jointer devices dress the cutting edge in situ, extending time between full knife changes and helping maintain consistent profile accuracy during long production runs.
ATS Automatic Position Controller
Optional
Automates spindle positioning between jobs, which reduces changeover time and operator error when switching between profiles — particularly valuable in mixed-profile production environments.

Machine Dimensions
Contact IWM for confirmed dimensions
Allow additional floor clearance beyond the machine footprint for infeed and outfeed support, extraction ducting connections, and safe operator access on both sides.
Machine Weight
Contact IWM for confirmed weight
A machine of this scale and construction is likely to require a floor loading check before installation — confirm with IWM and your structural engineer.
Motor Power / Electrical Supply
Contact IWM for confirmed electrical specification
Confirm three-phase supply availability and current capacity at your premises before ordering — a machine in this class will have a substantial electrical demand.
Spindle Speeds
Contact IWM for confirmed spindle speed data
Minimum Working Width
Contact IWM for confirmed minimum
Working Height Range
Contact IWM for confirmed height range
Extraction Spout Size / Requirement
Contact IWM for confirmed extraction requirement
Extraction sizing should be agreed with your dust extraction supplier at the point of specification — a machine of this width and spindle count will have a significant extraction demand.
Noise Level
Contact IWM for confirmed noise data
If measured noise exceeds 85 dB(A), acoustic screening or hearing protection zones will be required under UK noise at work regulations — confirm with IWM.

Is this the right
machine for you?

Choose the GL-645 planing moulder 450mm Width if...

  • Your regular work includes sections wider than 230–300 mm — beams, wide boards, or structural pillars — that a standard 4-sided planer simply cannot accommodate
  • You need the flexibility to configure spindle count and feed speed to match your specific product mix, rather than buying a fixed-spec machine
  • Production volume and throughput justify a heavy-duty wide-format machine, and downtime for knife changes needs to be minimised via optional jointer devices
  • You are specifying for a construction timber or engineered wood environment where surface quality across the full 450 mm width must be consistent at speed

Consider an alternate model if...

  • Your widest section is consistently under 300 mm — the GH-623 Moulder or the Fourside Planer Moulders GN-5S23/GN-6S23 may be a better-proportioned and more cost-effective fit
  • Your volume does not justify the scale of this machine — the Soukup GS-423 or GS-523 are worth discussing with IWM if your throughput is more modest
  • You are primarily processing standard-width softwood or hardwood sections for joinery rather than structural wide-format work — a smaller moulder in the range will likely serve you better
  • Floor space or electrical supply is constrained — talk to IWM about the Four-Sided Planer Model 180 PSE or other narrower alternatives before committing to a machine of this footprint
