KHM660B Door Machining Center: OneStation Forming for LockSlot and HingeSlot Machining
The Bottleneck Restricting Premium Wooden Door Production
For wooden door manufacturers, the separate processing of lock holes, lock slots and hinge slots has long been a key bottleneck limiting production quality and output. In traditional workshops, door panels go through cutting and edge banding first, then operators need to move workpieces across multiple separate stations to complete lock and hinge machining. Repeated lifting, positioning and clamping bring heavy manual workload, and positioning deviations easily occur during operation. Accumulated minor errors result in rough grooving and rejected door panels, which raises scrap rates and hinders the production of highquality finished wooden doors. Manual speed improvement cannot solve this fundamental problem. Factories need integrated intelligent equipment to streamline this process and support smart manufacturing for the door industry.
OneStation Forming: 8 Spindles for Simultaneous Lock & Hinge Machining
The KDT KHM660B door machining center is tailormade for highend wooden door production. It is an allinone machining center dedicated to lock hole, lock slot and hinge slot fabrication. With 8 groups of highperformance spindles, the machine enables lock and hinge feature machining at the same time within one working cycle. Door panels only require one single clamping, eliminating repeated flipping, crossstation transfer and secondary positioning. This greatly cuts labor intensity for operators and improves overall workshop operation safety. The integrated processing delivers neat, smooth grooving results, helping manufacturers produce premiumgrade wooden door products.

Premium Core Components & Intelligent Control System
PCbased Intelligent Visual Editing Software
Equipped with KDT selfdeveloped DoorLine PC intelligent control system, it adopts a visual interactive interface. Operators can preview machining layouts, edit parameters and monitor realtime equipment status directly on screen. The intuitive operation reduces manual calculation errors, and supports fast switching between different door specifications, lowering the technical threshold for new operators.
ServoAdjusted Automatic Worktable
The servodriven worktable automatically adapts to different door panel dimensions and completes selfpositioning and clamping. The optimized clamping structure firmly fixes the workpiece while avoiding scratches on door panel surfaces during conveying and processing. It protects the finished appearance of highend wooden doors and reduces cosmetic defects.
Precise Technical Parameters Matching Wooden Door Production
The KHM660B is built to fit mainstream wooden door production requirements:
- Machining width: 300–1200 mm
- Machining length: 1800–3000 mm
- Machining thickness: 30–70 mm
- Max moving speed: 60 m/min
- Total installed power: 35.3 kW
The X/Y/Z axes adopt 1.5 kW servo motors. Multigroup spindles with different power configurations (6kW,1.5kW,0.75kW) handle vertical and horizontal cutting for lock and hinge slots. It balances fast feed speed and stable cutting precision for longterm continuous production.

Flexible Connection Solutions for Diverse Production Modes
KHM660B supports two application modes to satisfy different factory layouts:
- Standalone unit with automatic loading & unloading: Ideal for factories with smallbatch customized orders. The auto loader/unloader reduces manual material handling.
- Integrated into full automatic wooden door production lines: Seamlessly connects with upstream and downstream equipment to build a fully automated workflow for mass wooden door manufacturing.
Typical Application Scenarios
This machine creates outstanding value for factories upgrading toward smart door manufacturing:
- Wooden door manufacturers pursuing highend finished products, requiring clean and precise lock & hinge grooves to guarantee product quality.
- Massproduction door factories looking to reduce labor cost, cut physical workload and raise workshop safety standards.
- Mixedproduction workshops with frequent changes of door sizes. Its adaptive servo worktable supports fast switching between different panel dimensions.
- Factories building full automated wooden door production lines, seeking reliable core machining stations for lock and hinge processing.
