Kolb spindle and milling head repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Kolb (Kolb Klüppelberg) spindles and milling heads — a German manufacturer of large-format gantry milling machines, known for its Cubimat and Pentamat ranges.
Kolb Klüppelberg, a German manufacturer of large-format gantry milling machines
TLDR: Kolb Klüppelberg (Germany) designs large-format gantry milling machines and machining centres, with flagship ranges such as Cubimat (VC, YC) and Pentamat, intended for machining massive parts in heavy mechanical engineering workshops.
Kolb Klüppelberg has built recognised expertise in the design of large-dimension gantry milling machines, with the Cubimat (available in VC, YC versions) and Pentamat ranges, whose most imposing models can handle parts weighing several dozen tonnes on tables that can exceed 9 metres in length. Kolb machines feature tool-changing systems that can hold more than a hundred tools, with configurations offering several interchangeable milling heads (vertical and angular heads) covering a wide spectrum of operations on a single machine.
A range of multiple milling heads for machining massive parts
TLDR: Kolb gantry milling machines feature SK 50 taper spindles, with installed power outputs of up to 120 kW and spindle torques of up to 5,500 Nm, combined with several interchangeable milling heads (vertical and angular) depending on the operation to be performed.
Kolb gantry milling machines in the Pentamat series feature SK 50 taper spindles, with rotation speeds typically ranging from 6.3 to 2,500 rpm across three speed ranges, spindle torques of up to 5,500 Nm and a total installed power of up to 120 kW on the most imposing configurations. These machines can be fitted with several interchangeable milling heads — vertical heads of various lengths and diameters, as well as an angular head — to adapt to the geometry of the part being machined. On gantry milling machines in the Cubimat range, dedicated to medium- to large-capacity applications, the spindles are also SK 50 taper, with drive powers of around 7.5 kW on the associated drilling configurations.

Frequently asked questions
Do you repair the interchangeable vertical and angular milling heads?
Yes, we work on these heads, whatever their length or diameter.
Do you work on high-torque SK 50 spindles (up to 5,500 Nm)?
Yes, we diagnose and repair these spindles, designed for machining massive parts.
What is the average lead time for a complete overhaul?
Allow around 20 working days in the workshop, depending on the condition of the spindle and the availability of parts (bearings, seals, specific components).
Do you work directly on site for large-size heads?
Yes, our team travels to diagnose and, whenever possible, work directly on site to avoid the full removal of bulky, heavy heads.
Do you offer a preventive maintenance contract for a fleet of Kolb machines?
Yes, we draw up preventive maintenance programmes tailored to your production pace, particularly relevant for heavy mechanical engineering workshops.
