Entry-Level Machining Centre from Hermle

A new, vertical-spindle machining centre, which can be supplied in 3-axis or 5-axis configuration, has been added to the range manufactured by Hermle, Germany. Called C 400 Basic, it is available in the UK through sole agent, Geo Kingsbury Machine Tools, Gosport.

The machine has fundamental attributes similar to those of Hermle's high-end models, such as a modified gantry design, mineral cast bed, and trunnion-mounted rotary table for the fourth and fifth CNC axes, all offering rigidity, low vibration and high machining accuracy. Stainless steel cladding throughout the working area is also to be found in the new machine. However, it comes with fewer options and is not intended to be automated.

Linear axis travels of 850 x 700 x 500 mm give the machine approximately equivalent capacity to the established C 42 U model. Workpieces weighing up to two tonnes can be processed on the fixed, 1070 mm x 700 mm table of the 3-axis version, while the 5-axis machine table can support 600 kg. The large swivel diameter of one metre between the side plates of the trunnion and the 650 mm diameter rotary table flattened on two sides to 540 mm provide versatility of production.

Spindle speed options are 15000 or 18000 rpm (20 kW / 180 Nm) and both are equipped with Hermle's patented collision protection system. In the event of a collision in the Z-axis direction, the energy is absorbed by six displacement sleeves, in many cases preventing spindle damage. In standard design, the C 400 Basic has a 38-tool magazine integrated into the machine bed. An optional, additional magazine with 87 tools is available. Tool breakage monitoring and measuring is included.

Minimal idle times result from 6 m/s2 acceleration to 35 m/min rapids in all linear axes. Trunnion swivel is at 25 rpm through +91 / -139 degrees, while C-axis positioning is at 35 rpm. Control is by the Heidenhain iTNC 530 CNC containing numerous Hermle user cycles that considerably improve or simplify machining processes.
