    ECT-Windotec Series

    E-Chain
    A double end tenoner in 3, 5, and 6-spindle configurations, built for joinery and window production. Both ends of a component are processed simultaneously — tenoning, scribing, and profiling done in a single pass rather than two.

    Typically chosen by

    • Joinery shops producing window frames or door sets who need accurate, repeatable tenoning at volume
    • Timber component manufacturers looking to consolidate multiple operations into one pass rather than running separate machines
    • Workshops stepping up from single-end or manual tenoning who need both ends processed simultaneously to reduce handling time

    Key specification considerations

    Available Configurations
    3-spindle, 5-spindle, 6-spindle
    Each step up adds horizontal scribing spindles or a second vertical profile spindle — choose based on the number of operations your profile requires in a single pass.
    Max. Cutting Height
    150 mm
    Fence Length
    2400 mm
    Supports longer components such as full-height window stiles without the workpiece overhanging unsupported.
    Machine Weight
    1850 kg (3-spindle) / 2200 kg (5-spindle) / 2450 kg (6-spindle)
    All variants exceed 500 kg significantly — floor loading capacity should be confirmed with your building surveyor before installation.

    Working Table Size
    800 x 400 mm (all variants)
    Fence Length
    2400 mm (all variants)
    Supports longer components such as full-height window stiles without the workpiece overhanging unsupported.
    Compressed Air Connections
    2 pcs (all variants)
    An on-site compressed air supply will be required — confirm pressure and flow rate with IWM before installation.
    Main Saw — Motor Power
    5 hp (all variants)
    Main Saw — Spindle Speed
    3000 rpm at 50 Hz (all variants)
    Main Saw — Spindle Diameter

    Top & Bottom Horizontal Spindles — Motor Power
    Not fitted (3-spindle) / 3 hp x 2 pcs (5-spindle) / 3 hp x 2 pcs (6-spindle)
    These scribing spindles are what allow the 5 and 6-spindle variants to undercut the shoulder cleanly — essential for a tight-fitting tenon on profiled sections.
    Top & Bottom Horizontal Spindles — Spindle Speed
    Not fitted (3-spindle) / 3000 rpm at 50 Hz (5 & 6-spindle)
    Top & Bottom Horizontal Spindles — Spindle Diameter
    Not fitted (3-spindle) / 40 mm (5 & 6-spindle)
    Top & Bottom Horizontal Spindles — Spindle Length
    Not fitted (3-spindle) / 150 mm (5 & 6-spindle)
    Top & Bottom Horizontal Spindles — Blade Diameter
    Not fitted (3-spindle) / 160 mm (5 & 6-spindle)
    Vertical Spindle 1 — Motor Power
    10 hp (all variants)
    Vertical Spindle 1 — Spindle Speed
    3000 rpm at 50 Hz (all variants)
    Vertical Spindle 1 — Spindle Diameter

    Vertical Spindle 1 — Cutter Diameter
    350 mm (all variants)
    Vertical Spindle 2 — Motor Power
    Not fitted (3 & 5-spindle) / 10 hp (6-spindle)
    The second vertical spindle on the 6-spindle variant allows an additional profile or cope operation in the same pass — relevant where your section requires more than one vertical cut.
    Vertical Spindle 2 — Spindle Speed
    Not fitted (3 & 5-spindle) / 3000 rpm at 50 Hz (6-spindle)
    Vertical Spindle 2 — Spindle Diameter
    Not fitted (3 & 5-spindle) / 40 mm (6-spindle)
    Vertical Spindle 2 — Spindle Length
    Not fitted (3 & 5-spindle) / 180 mm (6-spindle)
    Vertical Spindle 2 — Cutter Diameter
    Not fitted (3 & 5-spindle) / 350 mm (6-spindle)
    Machine Dimensions (L x W x H)
    2080 x 2700 x 1900 mm (3-spindle) / 2740 x 2700 x 1900 mm (5-spindle) / 3190 x 2700 x 1900 mm (6-spindle)
    Allow additional clearance beyond the machine footprint for workpiece infeed and outfeed, operator access, and extraction ducting — the 6-spindle variant in particular will require careful shop floor planning.
    Net Weight
    1850 kg (3-spindle) / 2200 kg (5-spindle) / 2450 kg (6-spindle)
    Gross Weight (packed)
    2000 kg (3-spindle) / 2350 kg (5-spindle) / 2600 kg (6-spindle)
    Packing Dimensions (L x W x H)
    2290 x 2000 x 2100 mm (3-spindle) / 2850 x 2000 x 2100 mm (5-spindle) / 3300 x 2000 x 2100 mm (6-spindle)
    Electrical Supply
    Confirm with IWM at point of enquiry
    Phase and amperage requirements vary by configuration and must be established before ordering to ensure your workshop supply is adequate — speak to IWM for the figure relevant to your chosen variant.
    Noise Level
    Confirm with IWM at point of enquiry
    Operating noise levels for multi-spindle tenoners of this type typically exceed 80 dB — acoustic treatment or hearing protection measures should be assessed for your workshop before installation.
    Feed Speed
    Confirm with IWM at point of enquiry
    Feed speed directly affects output rate and finish quality — discuss your target cycle time with IWM to confirm the available range suits your production requirements.
    Min. / Max. Workpiece Length
    Confirm with IWM at point of enquiry
    Minimum workpiece length determines whether your shortest components — such as short door rails — can be processed safely; confirm this against your section schedule before specifying.

    Is this the right
    machine for you?

    Choose the ECT-Windotec Series if...

    • You need to process both ends of a component simultaneously — window stiles, door rails, or framing members — and single-end processing is creating a bottleneck
    • Your sections require profiling and scribing in addition to tenoning, making the 5 or 6-spindle variant more appropriate than a basic tenoner
    • Your production volume justifies a dedicated double-end machine rather than repositioning workpieces through a single-end setup
    • You are producing repeat profiles at consistent lengths and need the fence and table arrangement to support accurate, repeatable batch runs

    Consider an alternate model if...

    • Your volume is lower or your profile requirements are simpler — the ECT-SET100 single end tenoner may be a more proportionate investment for smaller workshops
    • You only need grooving rather than full tenoning — the ECT-C2 Single End Grooving Machine is likely more appropriate and more cost-effective
    • You are processing flooring or decking components where end profiles are standardised at high volume — the dedicated Tenoners For Flooring range may be better suited to that application
    • Your lengths and tolerances demand CNC-controlled positioning rather than manual fence adjustment — the NC Type Automatic Double End Tenoner should be discussed as an alternative
