About this lot

DMG Deckel Maho DMU 70 – 5-axis machining centre

For sale is a used 5-axis milling center of the type DMU 70, built in 2008, with Heidenhain iTNC 530 control. The machine is designed for simultaneous 5-axis machining and is ideal for complex milling tasks in areas such as tool and mold making, mechanical engineering or single part production.

Specifications:
• Manufacturer: DMG Deckel Maho Seebach GmbH, Made in Germany
• Model: DMU 70
• Year of construction: 2008
• Spindle speed: up to 10,000 rpm
• Control: Heidenhain iTNC 530
• Supply voltage: 400 V / 50 Hz
• Power consumption: 25 kVA
• Tool holder: SK40 / BT40 (a wide range of tools available)

Condition & Special Features:
• The machine is functional and is currently still in productive use.
• Note: The stage hangs slightly by about 0.10-0.15 mm in the Y direction, which should be taken into account in precision applications.
• All axes and spindle run smoothly, the tool changer works reliably.
• Interior with typical signs of wear, well-kept general condition.

Operating hours according to control:
• Control on: 46,753 hours
• Machine on: 43,046 hours
• Program run: 11,333 hours

Counter values (BAUSER):
• Top (power on): 43,388 h
• Bottom (spindle/operation): 13,280 h

Accessories / Equipment:
• Extensive tool set with holders, clamping devices and milling cutters
• Tool trolleys and shelves included
• Various spare parts and accessories
Remarks:
The machine is overall in a used, but functional condition. It was regularly used and maintained in multi-shift operation. All main functions such as spindle, final drives, tool changer and control are intact. The machine is still in productive use, but will be retired as part of a restructuring.

Mechanical condition:
• The spindle runs smoothly and without increased running noise.
• The tool changer works reliably and without malfunctions.
• The guides and drives show normal wear according to age, but without functional failure.
• Note: The rotary table shows sagging of approx. 0.10–0.15 mm in the Y direction. This offset is measurable, but can still be well compensated for with a suitable machining strategy (e.g. clamping on flat surfaces, compensation above zero points).

Electrical/control condition:
• Heidenhain iTNC 530 control system runs stably
• Screen, keypad, controls and emergency stop are in good condition
• No known errors in memory or diagnostics

Optical Condition:
• Usual signs of wear on the trim and interior
• Viewing window with a slight matt finish, but functional
• Machine has been cleaned regularly and maintained

Application example (practical relevance):

The machine was most recently used to machine complex aluminum housings and 3D milled parts for prototyping and fixtures. Thanks to its 5-axis simultaneous capability, it is ideal for machining of:
• Freeform surfaces
• Multi-sided clamping (5-sided machining)
• Drilling patterns in inclined positions
• Mold inserts for toolmaking

Even if there is a table deviation, the machine can still be used economically with medium accuracy requirements (<0.05 mm).

Result:

This machine is ideal for companies that want to get started with 5-axis technology on a budget-conscious basis or expand their capacities in fixture and mold making – with a realistic view of age-related tolerances, but solid basic substance.

Frequently Asked Questions

How can I bid on a lot?

To place a bid, you need to have an account with Surplex. You can create one by clicking on 'Create Account' at the top right corner of our website. Once registered and after completing your profile, you can start bidding on your desired items.

What is reserve price?

A reserve price is the (non-visible!) minimum amount that a seller has set for a lot and is the lowest price for which the seller is willing to sell. The highest bidder who meets or exceeds this price wins.

If this price is not met, you can still have a chance to win. The closer your bid is to the reserve price, the greater your chance of winning this lot.

The lot is awarded to the highest bidder whose bid is equal to - or higher than - the reserve price at the end of the auction. If the highest bid has met the reserve price or more, the lot is sold immediately for this price.

How much does it cost to buy at Surplex?

There is a fee, the buyer's premium, added to each lot you win. The amount of the fee is shown on each individual lot. You see the buyer's premium for each lot when you are logged in as a customer at Surplex. Note that VAT is always added to your bid unless otherwise stated.

What is an auto bid versus a manual bid?

An auto bid is a way for you to automatically participate in a bidding process. You enter an amount you are willing to pay for an item and then automatic bids are placed for you up to your maximum bid - but only if necessary. Your maximum bid is hidden from other bidders during the auction. Placed auto bids are indicated by an "A" after the placed bid in the bid history. You need to update a manual bid every time someone outbids you. Keep in mind that an auto bid in the same level as a later manual bid will always lead the auction - because it was placed first.

How does the payment process work?
