This AUTOMATIC CYCLE machine, that was designed for the sawing of 1000 max. high blocks, is targeted to the production of large thickness slabs for tombstone art, building elements and paving stones.
The axis positioning is ensured by a PLC controlled system that comprises electronic vector regulators (inverters) and position digital transducers (encoders).
Disc down feed can be programmed during last phase of each cutting stroke thus permitting stroke immediate reciprocation and consequent “PENDULAR” motion that eliminates unproductive time.
The machine is equipped with VANISHING DISC that reduces noise level in any working position. Owing to the components high quality, to the sturdiness and precision of the mechanical parts, M950EF is an highly productive and reliable machine that maintains its great efficiency in time.
Two large contact surface “V” guides, machined onto the bridge, allow for trolley clearance- free sliding driven by a rack/pinion system.
Anti friction slides between trolley and bridge and continuous lubrication oil pits cut along the “V” guides enable the trolley stroke to be smooth and without vibrations even in case of high travelling speed.
Contrasting wheels, that compact trolley and bridge, allow discharging of the cutting stress directly onto the foundations.
The disc holder unit comprises an upper platform for main motor mounting and the spindle assembly that are connected to form a sole body through three ground chrome plated large diameter columns that slide vertically into protected housings machined onto trolley structure.
The two columns in front position absorb longitudinal stress caused by cutting action and improve disc performance.
Vertical displacement is driven in a balanced way through two synchronized screw/lead nut systems motioned by encoder controlled gear motor.
Bridge moves along two track ways fixed onto foundations. Bridge transversal displacement is driven through two rack/pinion systems that are synchronized through a connecting shaft motioned by an encoder equipped and inverter adjusted speed gear motor.
Bridge sliding along track ways is guided through two pairs of bearing wheels, with large centreline distance (1200 mm), that ensure bridge stability.
A system of auxiliary contrast wheels reacts to all vertical stress and allows for a very smooth disc performance。

Block Cutters T14 SM – T16 SM:
As a tradition Terzago the block cutters are built with dimensional generosity, with strong cast iron bridge for a time performance of undisputed length.
Built in the four columns frame and in the two columns frame.
For marble and granite, mono or multi discs.

Block cutter with automatic cycle for cutting marble.
Heavy duty type for transforming blocks of marble and similar stone into strips. Built in cast iron on four columns. Connecting beams and over-size bridge in cast iron.
Working speed of electrically powered blade-head unit can be regulated.
Hydraulic opening/closing of horizontal blade with dedicated line.
Transverse bridge movement is electric with rack/pinion system, running on interchangeable levels and positioning with encoder.
Vertical movement with four precision screws mounted on columns with four worm screws. Four counter-screws prevent accidental falling of bridge. One-speed step-cutting motor for rotation of screws synchronised by connecting shaft; encoder for positioning.
Main transmission by high performance tracks with oil-bathed gear box. Shaft rev. changes by pulley Motorised block carriage.
Centralised lubrication. Water-tight electrical cabinet.
Control panel with keyboard and real-time display of operator instructions, alarms and operating parameters.
