K-Series

Comprehensive machining with utmost precision

The horizontal boring mills of the K-series in planer type allow an efficient and precise complete machining of large prismatic work pieces. Due to the modular design and a wide scope of accessories, they can be precisely tailored according to the requirements of your work pieces.

Classification

  • K  Planer type
  • C  With automatic tool changer
  • U  With permanently integrated facing head
  • R  With RAM
  • G  High-precision boring mill

Boring spindle diameters available

  • 110, 125, 130, 150, 162 mm

The advantages at a glance

The planer type of the boring mill allows complete flexible machining of the work piece without conversion. The work piece change unit and the high level of automation guarantee minimal downtimes. The work piece change itself can be done either by means of a pallet changer or with an integrated table design.

Flexible and precisely designed

All linear axes have precision roller guides that guarantee a perfect machining result, just as the longitudinal compensation of the boring spindle and RAM, with engine speeds up to 5,000 rpm.

Optionally, the machines are available with hydrostatic guide ways, permanently integrated NC facing head or as high precision boring mill KG 110.

The K-series-design

The K-series is characterized by its compact and robust design: The ribbed box column, cast in one piece, guarantees the highest stiffness. The machine beds, arranged in T-form, are amply designed. Preloaded precision ball screws and linear compact roller guides achieve the highest machining accuracies. The hydraulic segment clamping of the table achieves high cutting performances.

By manufacturing all core components either in-house in Chemnitz or within the entire company group, UnionChemnitz can guarantee the highest quality. The K-series can optionally be equipped with a hydrostatic RAM including an additional infeed axis.

Options

Through numerous options, the machines of the K-series can be perfectly tailored to the requirements of your production:

Automatic tool changer

Depending upon the number of the required tools, you can choose between different automatic tool changers:

  • Travelling tool magazine with max. 60 tools
  • Magazine with max. 120 tools and linear feeder
  • Arena-magazine with max. 176 tools

Pick-up station

Milling heads are automatically changed by a shuttle located under the tool changer.

CNC-controls

Four variants are available: Siemens 840 D sl, Heidenhain iTNC 530, Heidenhain TNC 640 or Fanuc 31iB.

Twin table design

This stable work piece change unit can move loads of up to 60,000 kg.

NC-controlled facing head

The saddle can be integrated permanently in the head stock. The boring spindle can be used without removal of the facing head.

Precision boring mill

The precision boring mill KG 110 achieves the highest precision during boring, using an optimal thermal management system and many detail optimizations.

Comprehensive accessories

You can choose from a broad spectrum of milling attachments as well as rotary, traversing and tilting tables.
