KH4A 4 Axis ATC CNC Router for Curved-Surface and Side Machining
Combine flat routing, angled tool access, side drilling and grooving, curved-surface machining and automatic tool changes in one industrial swing-head platform.
Quick CNC can configure the KH4A around your drawings, materials, tool list, workholding, output target and workshop utilities.
Who Should Evaluate the KH4A?
The KH4A fits furniture factories, cabinet and door manufacturers, woodworking shops, CNC service companies, sign makers, plastics and composite processors, distributors and project buyers.
Typical Workpieces
- Furniture and door components
- Cabinet and custom woodworking parts
- Curved or angled wood features
- Signs, displays, foam patterns and suitable composite parts
Material Families
- Solid wood, MDF, plywood and particle board
- Melamine board, acrylic, PVC and plastics
- Aluminum composite panel and foam
- Suitable soft aluminum after process review
Reach Side, Angled and Curved Features Without Treating Every Job as Flat
A fixed vertical spindle is efficient for top-accessible profiles, pockets and drilling, but it cannot directly reach every side or angle. The KH4A spindle changes angle through a 180-degree range so the tool can approach side features, angled cuts and curved geometry.
The automatic tool changer supports multi-operation work. We recommend confirming tool reach, spindle angle, fixture clearance and collision space from the actual CAD file before configuration.
Where the KH4A Fits — and Where Another Machine Is Better
Choose KH4A When
- Parts need side holes, slots, lock or hinge features.
- Curved furniture surfaces or angled cuts need better tool access.
- One job requires several tools and automatic changes.
- The production mix combines flat and angled operations.
Choose Another Platform When
- All features are reachable from above: compare a 3-axis ATC router.
- Full-sheet breakdown is the main bottleneck: compare nesting equipment.
- Connector-hole throughput dominates: compare drilling-focused equipment.
- The part needs two rotary degrees of freedom or heavy-metal removal.

Speed and resolution are machine-reference values. Finished-part quality and output depend on material, toolpath, cutter, tool length, workholding, dust or chip control, calibration and inspection method.
Motion Architecture Built Around Tool Access
The KH4A uses rack-and-pinion movement on X/Y and a ball screw on Z. The welded frame, gantry, Taiwan linear guides, Yaskawa servo system and swing-head spindle operate as one machining platform.
Working area alone does not define usable clearance. We check spoilboard, fixture height, tool length, spindle nose, dust hood, safe retract height and swing-head collision space against the real part.
Select Options From the Production Requirement
We configure the reference KH4A with a 9 kW HSD swing-head ATC spindle, Syntec 6MB controller, Yaskawa 850 W servo motors and a vacuum table with a 7.5 kW pump.
- Custom working size: choose it only after checking part size, fixture allowance, tool-change clearance and workshop access.
- Becker pump: evaluate it from material porosity, leakage, zone layout and service requirements.
- Rotary attachment: use it for suitable cylindrical or indexed parts; it does not replace the swing-head function.
- Tool capacity: confirmed with the selected machine configuration and operation sequence.
Define the Engineering Boundary Before Quotation
Quick CNC can configure the working area, workholding, pump selection, tooling, dust collection interfaces, electrical supply and selected accessories after reviewing project data. Every change is checked against usable travel, machine footprint, loading direction, service access and operator sequence.
Part Data
Raw and finished dimensions, drawings, material and critical surfaces.
Process Data
Operations, access angles, tool diameters, depth per pass and cycle target.
Site Data
Voltage, extraction, air, floor, door size, lifting and operating space.
Match Tooling, Workholding and Acceptance to the Real Part
Tool choice starts with material, cutter diameter, depth per pass, surface requirement and operation sequence. Flat sheets can use the vacuum table when sealing area is sufficient. Small, porous, irregular or high-force parts may need mechanical clamps or dedicated fixtures.
Quick CNC can arrange a representative sample plan using the buyer’s drawing, material or equivalent stock, critical dimensions and inspection method.
Set the Acceptance Method Before the Machine Is Built
Define operations, tools, acceptance dimensions, surface requirements, cycle target and evidence format before order release. Quick CNC can prepare a pre-shipment checklist and provide the agreed machine documentation.
Model-specific declarations or certificates are supplied only when their product and destination scope is confirmed in the order documents. Archive workshop imagery supports machine identity and production context; it is not presented as a completed customer test record.

Choose the Machine From the Access Problem
KH4A Swing-Head Router
Best when the spindle must approach side, angled or curved features while the workpiece remains on the table.
3-Axis ATC Router
More economical when every feature is reachable from above and the job is primarily flat routing.
Rotary-Axis Configuration
Use when the workpiece itself must rotate in a chuck and tailstock for cylindrical or indexed work.
5-Axis / Specialized Equipment
Use when the geometry requires two rotary degrees of freedom, more complex multi-face access, nesting automation or drilling throughput.
Production Patterns to Consider for KH4A
Evaluate KH4A for curved furniture components, door edge and lock-slot work, decorative panels, angled grooves, sign and display parts, foam patterns and mixed 2D/3D jobs.
These are process-fit scenarios, not customer-case claims. Final suitability is established from the drawing, workholding plan, toolpath and agreed sample or acceptance method.

KH4A Buying Questions
Is KH4A a rotary-axis CNC router?
The standard machine role is a swing-head router: the spindle changes angle through a 180-degree range. A separate rotary workpiece attachment can be discussed as an option for suitable cylindrical or indexed parts.
Can KH4A replace a three-axis ATC router?
It can perform conventional flat routing and adds side or angled access, but the extra axis and programming requirements are unnecessary when every feature is reachable from above.
Can it cut soft aluminum?
Suitable soft aluminum may be evaluated after checking rigidity, spindle, cutter, lubrication or air blast, workholding, chip evacuation, alloy, thickness, depth per pass and finish target.
How many tools does the automatic tool changer hold?
The exact capacity is confirmed with the selected KH4A configuration. The reference machine uses a linear automatic tool changer, but no conflicting tool-count figure is published.
What information is needed for a quotation?
Send drawings, material, dimensions, required operations, tool requirements, production target, software, utilities, destination and acceptance criteria.
