The capability and versatility of the Lagun range is key to its success, particularly the TM series of cross moving column machines.
The four machine TM range has X-axis travel up to 5,000mm combined with Y-, Z, and V-axis travels of up to 1,300/2,000/1,500mm respectively. With travels of this size the machines are also built to handle large workpieces weighing up to 10,000kg, and with the V-axis (which holds the digital spindle) fully retracted it is possible to fit components up to 2,500mm diameter on the machine’s rotary table. With the turning option specified, this rotary table can rotate at up to 400rpm to create a highly capable turning system.
For milling, the TM series can be specified with a choice of six milling heads, three of which are universal Hure-type heads with spindle speeds ranging from 3,000 to 6,000rpm. An orthogonal-style head can also be specified for the machine, which gives index increments of 1° in both planes of movement with positioning controlled by two encoders and Hirth couplings, making it ideal for turning operations. Alternatively, a choice of two horizontal heads, of differing lengths scan be specified.
With one of the Hure, or orthogonal, heads fitted, the TM series is capable of machining five sides of a component completely. With either the 40 or 60 position chain-type toolchanger, complex parts can be machined without interruption.
Given the large scale of the Lagun TM machines, the largest weighs 29,000kg with a footprint of 9,200mm x 7,371mm and spindle travel of 2,700mm (Y + V axes) and 2,000mm in the Z-axis, guarding also needs to be taken into consideration. Here, Lagun can provide various options, one being to fully enclose the machine or, alternatively, a more cost-effective option is to use side curtains and fencing to separate the operator from the working environment.
With the Lagun range, and the TM series, the ability to machine large and heavy components is fully possible. The larger MM and ML machines in the range have X-axis travels up to 12,000mm and the capability to machine parts weighing up to 14,000kg, yet still retain excellent agility with traverse rates up to 20m/minute.
With production increasing across sectors such as die/mouldmaking, automotive, aerospace, and renewable energy, as well as general machining, RK International is confident that it will see a rise in demand for the Lagun range here in the UK and Ireland.
