GN-6S23 Planer

Gau Jing
A six-spindle four-sided planer moulder for joinery and timber workshops that need to dimension, surface, and profile stock in a single pass. Handles working widths up to 230 mm and feed speeds up to 40 m/min, with the option to configure between four and eight spindles.

Typically chosen by

  • Joinery shops producing window sections, door components, or moulded profiles at volume
  • Timber processors who need four-sided dimensioning and surface finish in a single pass
  • Workshops stepping up from a smaller four-sider and needing additional spindles for more complex profiles

Key specification considerations

Spindles
6 (4–8 spindle configurations available)
More spindles allow more profile complexity or additional operations in a single pass, reducing handling and secondary machining.
Working Width
10–230 mm
The 10 mm minimum suits small-section mouldings; the 230 mm maximum covers most UK joinery stock including standard door and window profiles.
Feed Speed
6–40 m/min
Variable feed via frequency converter lets you slow the machine for harder species or complex profiles and open it up for straightforward dimensioning runs.
Spindle Speed
6,000 rpm

Working Width (min–max)
10–230 mm
The 10 mm minimum suits small-section mouldings; the 230 mm maximum covers most UK joinery stock including standard door and window profiles.
Working Height (min–max)
7–160 mm

Spindle Speed
6,000 rpm
Motor Power (individual spindles)
5.5–18.5 kW per spindle (configuration-dependent)
Each spindle is independently driven — confirm your three-phase supply capacity with IWM when specifying, as total connected load across all motors is substantial.
Lubrication
Centralised lubrication system
A centralised system means routine lubrication points are serviced from one location, reducing downtime during maintenance.
Air Pressure Adjustment
Centralised
Centralised pressure control allows the operator to adjust feed pressure across the machine from a single point, rather than setting each unit individually.
Machine Dimensions
Contact IWM for current dimensions
Allow additional clearance in front of and behind the machine for infeed and outfeed of long stock — as a guide, plan for at least the length of your longest workpiece at each end.
Machine Weight
Contact IWM for current weight
Cast iron construction means this machine is heavy; floor loading should be checked before installation — contact IWM for the current weight figure.
Electrical Supply
Three-phase — confirm supply requirements with IWM
This machine requires a three-phase supply; verify available amperage at your distribution board before ordering.
Extraction Spout Diameter / Quantity
Contact IWM for extraction specification
Adequate extraction is essential on a six-spindle machine — discuss spout sizes and airflow requirements with IWM or your extraction supplier when planning the installation.
CE Marked
Yes
CE marking confirms the machine meets applicable EU/UK machinery safety directives, which is a requirement for legal use in UK workplaces.

Is this the right
machine for you?

Choose the GN-6S23 Planer if...

  • You need six spindles to run more complex profiles or combine operations in one pass without secondary handling
  • Your production volume justifies a larger, heavier-duty four-sider over a more compact entry-level machine
  • Surface finish quality is critical and you want high-precision spindles as standard in the machine's construction
  • You want the option to configure the machine with up to eight spindles as your profiling needs develop

Consider an alternate model if...

  • Your profiles are straightforward and four spindles are sufficient — the GN-5S23 or Soukup GS-423 / GS-523 may be a more proportionate choice for your operation
  • Your maximum working width exceeds 230 mm — the GL-645 handles up to 450 mm width and may be more appropriate for wider stock
  • You need a simpler dedicated moulder rather than a four-sided planer moulder — the GH-623 Moulder may be worth discussing
  • Your throughput requirements are modest and a smaller or simpler machine would avoid unnecessary capital outlay — talk to us and we can help assess the right level
