Ziersch GmbH - Portal grinding machines

Features
For the grinding of large work pieces with a width of up to 2,200 mm. Large and heavy work pieces can quickly and effectively be machined on these portal grinding machines.

Portal grinding machines with standard equipment alone are available at a very good price/performance ratio. Standard equipment includes amongst others the following:

Sturdy, cast iron execution of all machine components
Scraped and turcite coated slideways in the X-axis
Preloaded precision linear guideways in the Y-axis and Z-axis (Bosch Rexroth)
Hydraulic table motion with return cooling unit
Electro-mechanic cross- and vertical motion
Measuring system in vertical axis (Heidenhain) for precise positioning
Paper band filtration unit with 1,700 l tank and 5 bar pressure pump
Fully automatic grinding and dressing cycles
Additional magnetic separator for prefiltration of the paper band filtration unit
Integrated rinsing channel
Machine lamps
Table-mounted dressing device
Partial encapsulation of the machine with sliding door
High-performance spindle drive for efficient grinding

Control system features:

Automatic vertical infeed with dressing amount compensation
Fully automatic grinding cycle with dressing cycles
Easy operation via touchscreen
Large and clear colour screen (10.4")
Electronic handwheel, usable in vertical- and cross axis
