01 · Why KnorrTec
Four reasons why KnorrTec is the right partner for your machine cabling.
As a cable assembler — not a distributor — we bring the technical expertise that is essential for reliable connections in machine tool and special-purpose machinery manufacturing. We don't supply standard off-the-shelf goods; we develop the connection that fits your machine.
Technical consultation in advance
Before we start assembly, we clarify your requirements together — machine type, control system, cable routing, ambient conditions. That way, the cable set is right the first time.
Custom assembly from quantity 1
No minimum order quantity. Exactly your length, your connector, your protective sheath — from the prototype for the first special-purpose machine to series production for the model line.
Manufacturer-independent
Compatible with all common control and drive systems. We know the connection standards used across the market and supply the right connection — regardless of your machine's manufacturer.
Tested quality
Every cable assembly is 100% electrically tested. Connectors with protection ratings up to IP69K for use in areas exposed to coolant — with test report on request.
02 · Technical Requirements
What cables for machine tools need to be capable of.
Standard industrial cables quickly fail in the harsh environment of machine tools. Knowing the requirements of axis drives, spindles, and control cabinets is what enables the right choice of cable material — this is the consulting expertise KnorrTec brings to the table.
Oil resistance
Coolant and hydraulic oil attack standard PVC sheaths. In machine tools, oil-resistant PUR or TPE sheaths are essential.
High flexibility
Cables in cable carriers on linear axes go through millions of flex cycles — requiring fine-wire strands to class 5/6 with a robust outer sheath.
EMC shielding
Servo and spindle drives generate strong interference fields. Braided shielding with high coverage reliably protects signal and encoder conductors.
Compact design
In tight control cabinets and machine housings, every millimeter counts. We assemble compact connector and cable solutions for confined installation spaces.
Temperature resistance
The heat generated near the spindle and at servo drives requires heat-resistant sheath materials and carefully planned routing away from critical heat sources.
Vibration resistance
In continuous operation, cables on machine tools are exposed to constant vibration. Strain-relieved connections and robust conductor insulation prevent contact fatigue and cable breakage.
"No off-the-shelf standard cable. Every connection for your machine tool was discussed with you beforehand."
KnorrTec — cable assembler, not a distributor.
03 · Made-to-Measure Assembly
From requirement to finished cable — starting at a single piece.
We are not a catalog supplier. Every cable we deliver was specified together with you and manufactured at our facility in Beratzhausen. That's the difference between a connection that holds — and one that fails.
Inquiry & Consultation
You describe your requirements: machine type, control system, cable routing, environment. We ask the right questions — and together we find the optimal cable specification.
Technical specification
Our team determines conductor cross-section, flex class, shielding design, sheath material, connector, and protection rating — documented as a drawing for your records.
Assembly
We manufacture at our facility in Beratzhausen — exactly your length, your connector, your imprint. From a single unit for a special-purpose machine to series production for a model line.
Testing & Delivery
Every cable is electrically tested. Delivered with a test report — on request with labeling and set packaging for direct installation on the machine.

04 · Applications
Three machine categories — one source.
Whether a CNC machining center, a custom special-purpose machine, or the modernization of an existing system — we know the specific cable requirements of each area and deliver the right cable assembly.
B.01
CNC machining centers
Axis drives, spindles, and tool changers place high demands on flexibility, oil resistance, and interference immunity — the right cable for every axis.
- Servo motor cables for axis drives
- Encoder cables for spindle and axis feedback
- Shielded control cables
- Connector cables for SIMATIC MICRO-DRIVE
B.02
Special-purpose machinery manufacturing
Custom automation solutions require custom connection technology. Especially with small batch sizes, our cable assembly from a single unit pays off.
- Custom-made from a single unit
- Structural assemblies for fast integration
- Customer-specific pin assignment
- Short lead times for prototypes
B.03
Retrofit & modernization
When retrofitting older machines with new control technology, old and new connection standards collide. We adapt the connection — not the other way around.
- Adapting old connector standards to new ones
- D-Sub and circular connectors for existing systems
- System cabling for new control cabinets
- Single units with no minimum order quantity
05 · Product Categories
The product range for machine tools & special-purpose machinery.

08 · Frequently Asked Questions
For cable assembly for machine tools.
From how many units does KnorrTec assemble cables for machine tools?
From a single piece. There is no minimum order quantity. This is especially important in special-purpose machinery manufacturing with small batch sizes — we produce prototypes and series runs using the same materials and processes, with no surcharge for small quantities.
Why are standard cables often not sufficient for machine tools?
Coolant and hydraulic oil attack Standard PVC sheaths cable carriers on linear axes call for highly flexible strands, and servo and spindle drives generate interference fields that require effective EMC shielding require. Add to that tight installation spaces in the control cabinet and vibration during continuous operation. KnorrTec advises on which cable material suits your specific machine.
How long does a custom assembly take?
You will receive technical feedback and a quote within 24 hours after your inquiry. Prototypes are typically available in 1–2 weeks available. Series production depending on scope and material availability on request — we communicate delivery dates transparently and reliably.
Can KnorrTec also support retrofit projects involving older control technology?
Yes. When retrofitting older machines with new control technology, we often see old and new connection standards collide. We adapt the connection to your existing machine and the new control system — rather than tying you to a specific brand. Simply tell us the machine type and existing connections in your inquiry.
Which control and drive systems does KnorrTec supply matching cables for?
We assemble manufacturer-independent for all common CNC controls and drive systems. For Siemens SIMATIC MICRO-DRIVE, we also maintain a dedicated product category with pre-assembled connector cables — for all other systems, simply tell us the machine type and connection standard.
