Face polishing and brushing machine

Bull 3500 grinding machine is optimal surface grinding machine for various shape tombstones and thin plates. The massive steel construction guarantees a non -vibrating, high quality grinding result. The special constructional demands characteristic for stone machinery, have been carefully taken into consideration already at the planning stage. Especially guides, bearings, guards and corrosion protection have been precedence. All the mechanical solutions are stated good at practice. The controls, functions and operating itself has been developed together with the professional workers in the stone industry. This means that interface etc. are very easy to use and the user's point of view has been expressed in that all the way! The graphic display on the control panel shows very clear and illustrative. Therefore the information is extremely easy to set and read. The important parameters will not be forgotten by the operator. All settings the stone positions and dimensions (even up to 10 different workpieces as standard) is easily and quickly done by teach-in. The straight edge of the stone is set facing the operators side, otherwise the stone can be of various shapes. For rectangular workpieces only two crosswise points are needed! The shape of the stone is followed with the joystick, and the reference point is pointed by water stream. These teach-in points are given by pushing the teach- in button. The remote acces is also as standard. The user can call Kasins CustomerSupport, which thereafter takes direct contact through the ethernet with the Bull 3500 control unit and communicates directly with it. (customer must have an ethernet connection to the machine)

Automatic head exchange for 7 heads.
