Automatic Down feed/自动向下进给单元

Electronic control for down feed of the grinding head can be adjusted at the operating panel as well as the drive motor’s stepping controller. Depending on the grinding modes, up to three different grinding parameter recipes can be stored.

The parameters of the grinding head for starting position, feed rates and spark out are freely programmable.

Technical Data/主要技术参数

Set of Anti Vibration Pads (90-00451-0064) /一套抗震动衬垫

to absorb ambient vibrations, which could influence the grinding pattern negatively.

Centralised Lubrication System (61-00321-0032) /中央冷却系统

a time-controlled, automatic supply of all lubrication points through a central pump

Additional cost for software modification/软件变更额外收费
for compensation of the different wheel wear of the two grinding wheels without Marposs Electronic Sizing Control. No automatic control circuit, the wheel wear values have to be calculated.
Also incorporated in the control is a cycle counter for control of the TWIN grinding wheel wear.

Options/可选配置项目

Chamfering spindle ( 2/60-00285-0101) TSAV 80 du x 280

倒角研磨主轴装置（倒角研磨可作为配置一体机用）
A second grinding station is used for simultaneous chamfering of the blocks.
The grinding process is a single step one. A short stroke cylinder (60-00351-0067) automatically lifts the grinding wheel when the table is in fast motion, thus conserving the work piece surface. Positioning of the spindle is effected manually.

Spindle speed:                    n= 4000 rpm
Power                          N= 2,2 kW
Voltage / Frequency            400 V, 50 cycles

Block handling with automatic rotating unit and intermediate depositing rack

工件全自动取料和放料操作系统

The work piece to be ground is taken from the intermediate depositing table, placed on the machine table by a transport system and subsequently clamped onto the machine table by vacuum.
The work piece is automatically turned in the grinding area by the rotating unit to enable grinding of all 4 work piece surfaces. At the end of the grinding-/polishing cycle the work piece is placed back on the intermediate depositing table.

Electronic Sizing Control (60-00213-0258)/电子尺寸控制系统

Before grinding, a one point measurement is carried out at each side of the brick. The value measured is transmitted to the grinding head down feed controller which calculates the starting position and the down feed value per grinding step.

Before grinding, the sizing control unit also monitors the block input dimensions, as  certain block dimensions are necessary to start the grinding process,

Power supply: 230 V, 50/60 cycles
Complete with all accessories.
