KR-1000 Cylinder Head and Engine Block Grinding Machine by Industrias Kras
Solidity, efficiency and precision are the characteristics that distinguish the KR-1000, the resurfacing machine for cylinder heads and engine blocks produced by Industrias Kras and intended for all those engine workshops that seek above all the quality for their machinery.
Produced respecting the traditional production systems of machine tools, the KR-1000 is totally made of spheroidal cast iron in all its main components.
Base, table, column and head are in fact made by means of cast cast iron, thus giving extreme solidity and robustness to the whole machine.
The table slides on the base through a system of flat and prismatic guides and is moved by a variable speed gearmotor, which acts directly on the recirculating ball screw which allows the table to be moved.
The head slides vertically on the column by means of dovetail guides, which is also operated thanks to the ball screw.
Certain construction characteristics of the KR-1000, such as the maximum stroke of the table, the distance between the column and the center of the table and the distance between the cutter plate and the table allow the KR-1000 to be the ideal heads and blocks resurfacing and milling machine for medium size engine workshops.
The variable speed of rotation of the grinding wheel and the adjustment of the table feed speed further extend the working possibilities of this exceptional resurfacing machine for heads and blocks.
The possibility of working both with abrasive and coolant sectors, or with the brazed carbide tool that is supplied with the standard equipment, increase the work potential of the KR-1000.
Additional optional accessories, such as the cutter plate for PCD and CBN inserts or the supports for inclined heads, can extend the working capacity of the KR-1000, meeting the needs of more experienced engine rebuilders.
An adjustable arm on the right side of the operator supports the control panel which houses all the drives:
- Wheel rotation start button
- Wheel rotation stop button
- Wheel speed adjustment knob
- Wheel rotation speed digital display
- Coolant pump start button
- Coolant pump stop button
- Right table movement push button
- Left table movement push button
- Stop table push button
- Table feed speed adjustment knob
- Digital display of table feed speed
- Rapid table movement button
- Table feed mode selector
- Emergency stop button
EQUIPMENT AND ACCESSORIES
Thanks to the wide range of accessories supplied in the standard equipment of the KR-1000, the machine is immediately usable by any operator.
There is also the possibility of integrating and enriching the KR-1000 with interesting and additional optional accessories, thus making it even more complete and performing resurfacer for cylinder heads and engine blocks.
