Product description

Heidenhain 631940-01 is an HDR, or Hard Disk Removable, unit for the MillPlus IT CNC control and serves as the control system's central mass-storage device. The unit contains pre-installed NC software 538952-02 in version V600, Service Pack 05, and is intended as a ready-to-use replacement for defective or worn original drives. Its 30 GB capacity provides space for system files, NC programs, machine parameters, tool data and cycles. The 2.5-inch drive uses an IDE (ATA) interface and fits the slide-in bays of Heidenhain main computers MC 420, MC 422 B, MC 422 C, MC 422 D and the MC-6xxx and MC-7xxx series without modification. The associated MillPlus IT control family is used in milling machines, boring machines and machining centres in medium and higher performance classes. It supports multi-axis contouring control, extensive cycle programming, ISO/DIN compatibility and interfaces for CAD/CAM integration. After an HDR replacement, the control is intended to resume operation with the stored machine data and NC programs without a lengthy reinstallation or configuration process. The removable cassette design supports rapid exchange without specialist tools. Heidenhain 631940-01 is intended as a direct replacement for continued production operation. Heidenhain 631940-01 is available directly from our warehouse in Germany.

Frequently asked questions

Contact us
Is there a warranty?

Yes. We provide a 14-day functional warranty for used items. The component must be functional on arrival, and the warranty applies only while the warranty seal remains undamaged.

Depending on availability, we will either provide a replacement or refund the full purchase price after the item has been returned. Further details are set out in the terms and conditions supplied with our quotation.

How quickly do you ship, and which shipping options are available?

We normally dispatch available items immediately and, in many cases, on the same working day. For urgent requirements or machine downtime, we will identify the fastest suitable option and can confirm a specific delivery window on request. Express shipping and collection from our premises are also possible by arrangement. We ship worldwide using reliable parcel and freight carriers; freight shipments may require additional preparation to ensure safe delivery.

Is there a guarantee?

Yes, we provide a 14-day functional guarantee for used items. This means the component must be operational when received.

Please note that the guarantee only applies when the warranty seal is undamaged.

How quickly do you dispatch and which shipping options are available?

We generally dispatch immediately - in many cases on the same working day. For particularly urgent requirements or machine downtime, we find a suitable solution as quickly as possible and provide a specific delivery window on request.

Express shipping or collection from our premises is also possible, depending on the situation. State your requirements during the ordering process or contact us directly.

We ship worldwide and work with reliable shipping partners, from parcel services to freight forwarding. Freight shipments normally require some preparation so the goods arrive safely and undamaged.

Which payment methods are available?

Payment is normally made by bank transfer against invoice. Payment is due within 10 calendar days of receiving the goods.

As a rule, we offer purchase on account for all customers. In individual cases, such as new customers or particularly high-value components, we may agree advance payment. This decision is made individually and communicated transparently.

Can we return items if they were ordered incorrectly?

Because we sell exclusively to business customers (B2B), there is no general right of return and no consumer right of withdrawal.

Please note that returns of functioning goods are generally excluded. In justified exceptional cases, we can assess an individual solution, but this is not the standard procedure.

Is there a discount when ordering several items?

For larger order quantities or several items of one type, we can offer individual discounts.

Simply send us a quick enquiry - we check availability and will gladly prepare a tailored quotation with quantity pricing.

Do you also purchase industrial spare parts?

Yes, we also purchase automation components, such as frequency inverters, PLC assemblies, panels, servo motors and CPUs. Components from Siemens, Lenze, Schneider Electric, Control Techniques or Heidenhain are especially sought after, and other brands are also possible.

The process is straightforward: email us an inventory list or overview photos at info@reha-industriekomponenten.de. We calculate a market-based purchase price and send you an offer.
