Simultaneous 5-axis high precision Storm VMC

The Storm SV 700-5x is a simultaneous 5-axis, high precision vertical machining centre from Colchester-Harrison that has options of the latest high specification Heidenhain or Fanuc control, a choice of 15,000 rpm 15 kW or 11 kW, 12,000 rpm drives and either high speed 48 m/min or 32 m/min rapid traverse rates.

The Storm SV 700-5x has a machining volume of 700, 500 and 355 mm, in XYZ respectively, with a tilting A-axis high rigidity trunnion with a sweep of –100 deg to +30 deg to an accuracy of + 3 sec. The 360 deg rotational C-axis of the 250 mm diameter table is programmable up to 16.7 rpm with a repeatability for position within + 2 sec.

The machine has a high rigidity Meehanite cast base and saddle with heavy duty THK 45 mm width guideways. Oversize guide blocks have been specified to provide the perfect platform for combined five-sided approach, single cycle machining operations.

Full hydraulic locking is employed giving increased rigidity and a two-section worm creates a five times greater contact surface area than normal compound double lead systems. Not only does this system generate higher accuracy and a durability in operation, but it also maintains a backlash tolerance between 5 and 8 microns
