Kaltenbach used machines and more information

Information about the manufacturer KALTENBACH GmbH + Co. KG

The Kaltenbach Group is an internationally active family-owned company with experience from more than 130 years of machine manufacturing.

The Kaltenbach company was founded by Julius Kaltenbach in Lörrach in 1887. In 1953, with Dieter Kaltenbach in the 3rd generation, the development of circular saws was advanced and expanded. In 1987, the company invested in a new production facility for transport systems in nearby Burnhaupt-le-haut (France).
From 1994 onwards, rapid company expansion took place at Kaltenbach through in-house developments in the band saw sector, punching-shearing system sector and acquisitions of machine manufacturers in the same industrial segment. For example:

• Company Gustav Wagner from Reutlingen, Germany, a manufacturer of profile drilling rigs, flat steel machining centers and circular saws

• Company APS from Wateringen, Netherlands,
  a manufacturer of profile drilling rigs, angle punching and punching-shearing equipment.

• Company Gietart from Hengelo, the Netherlands,
  a leading manufacturer of blasting equipment and complete systems for surface treatment as well as surface preservation.

So under the owner Valentin Kaltenbach in the 4th generation, the family business Kaltenbach became a leading global total supplier in the market of steel processing machinery. In 2017, the company was sold by Valentin Kaltenbach to Zobel Values AG. As a result, the company has a financially strong shareholder who plans for the long term.

Kaltenbach, with its headquarters in Lörrach, in the border region to France and Switzerland, is one of the leading internationally active machine and plant manufacturers. Thanks to the Kaltenbach Group's international production facilities, service and sales offices, service and spare parts are guaranteed, even for older machines.

Saws for profile steel processing

The band saws and circular saws that are part of Kaltenbach's product range made the manufacturer the leading supplier of sawing technology in metal construction, plant engineering, steel construction and steel trade. The SLK, KKS, MSK, KBS and HDM series of circular saws are available for a variety of sawing applications.

Kaltenbach bandsaws

The KBS bandsaw machines are all equipped with a miter cutting device and are therefore especially designed for profile steel processing. The abbreviation DG listed in the product designation stands for double miter device and NA for automatic feeder. The Kaltenbach Proficut software package is used for easy programming of the band saws.

KALTENBACH HDM cold circular saw

The HDM circular saw series with the large saw blade diameters has been around for many years and in a large number of different models. In some cases, the Kaltenbach circular saw models HDM 750, HDM 800, HDM 1300, HDM 1430, HDM 1431, HDM 1432, etc. are used in various applications around the world. Kaltenbach cold circular saws have a particularly clean cutting action and are characterized by very high reliability. Even if the regrinding of the segment saw blades enables the saw blades to be used several times, the use of band saws is at times more favorable. Due to the use of modern band saws, the use of the large circular saws continues to decline.

KALTENBACH profile drilling machines

Kaltenbach profile drilling machines are all CNC controlled and can be combined with a suitable sawing system. Usually, a band saw is used for a saw-drill combination. However, Kaltenbach is the only manufacturer known to us who also still builds the large cold circular saw and combines it with a drilling machine. For the respective application numerous equipment variants are available from the low cost machine up to the fully automatic profile drilling line. The plants are supplemented with an extensive material transport system consisting of roller conveyors and cross conveyor systems.

KALTENBACH sheet metal processing centers

The Kaltenbach sheet metal processing center is a modern and economical equipment for automatic processing of sheet metal and flat steel. Due to its versatility, the sheet metal processing center finds application in steel construction, steel trade, metal construction and plant engineering. The combination of several types of machining such as drilling, tapping, countersinking, center punching, milling, mill marking, oxy-fuel cutting and plasma cutting are the strength of the sheet metal working center. Depending on the year of manufacture, all or some of the above functions are part of the equipment.
The WBZ and KF series of sheet metal processing centers have been proven and reliable production machines for more than 30 years of hard use in the flat steel processing environment. These solid machines have been continuously developed during their development phase and, depending on the year of manufacture, are equipped with a wide range of special features. For example, the new sheet metal working centers are equipped with one or two machining units for oxyfuel cutting and plasma cutting as well as one or two powerful drilling units with tool changer. The high drive power combined with high spindle speeds enables the use of carbide tools for drilling, milling and marking.

Series overview of WBZ and KF sheet metal working machines:

KALTENBACH KC notching robot, profile processing robot

The Kaltenbach KC notching robot is suitable for fast notching of steel beams, H profiles, U profiles, angle profiles and square tubes. Notching with a CNC-controlled automatic flame-cutting system has been a beneficial revolution for series production by reducing the amount of notching previously done manually with a hand cutting torch.

The Kaltenbach KC notching robot system consists of a stable machine gantry with a Kuka robot flanged to the crossbeam. The proven Kuka robot ensures that all notching positions can be reached with its motion axes.
Eight motion axes ensure the precise notching position of the sectional beams, angle steel or square tubes. Here, six movement axes are covered by the compactly built Kuka robot. The axis mounted on the crossbeam ensures the positioning of the robot in the transverse axis. The movement of the workpieces in the X-axis (longitudinal axis) is carried out by a solid pushing measuring carriage, which is guided along a rack on the roller conveyor on the infeed side. This, in conjunction with the driven roller conveyor, allows even heavy sectional beams to be moved and economically notched. A hydraulic clamping system ensures that the workpieces are held in place during the thermal cutting process. Depending on the machine type, the KC robot is optionally equipped with an oxyfuel flame cutting unit and/or a plasma cutting unit. Notching with a plasma cutting unit from Hypertherm or Kjellberg is faster than oxyfuel cutting, but requires perfect extraction of the resulting combustion gases and fine dusts.

Good operator skills are needed to program the Kaltenbach KC robot. The CAD data provided by the customer or the design department is transferred in DSTV format to the plant's CUT Manager via the DSTV interface. This can be done with an online connection or via a data carrier. This results in a 3D representation of the components. A "Moses" software subsequently generates the necessary robot data from the DSTV data. The "Moses" software from AUTOCAM Informationstechnik GmbH is an automatic CAD and CAM link to the Kaltenbach KC robot controller for notching in the plasma and oxyfuel cutting process. Then, for new workpieces, the first step is collision checking and verification of the robot axis positioning. This is followed by thermal notching and subsequent removal of the finished components with the roller conveyor on the outfeed side.
