KR-1500 Cylinder Head and Block Resurfacer by Industrias Kras
Made following the traditional construction methods of machine tools, the KR-1500 is placed in the market segment of resurfacing machines for large engine heads and blocks.
Let’s take a look at the features and functions that distinguish the KR-1500 head and engine block resurfacer from Industrias Kras
The basic structure is entirely made of solid spheroidal cast iron, which gives characteristics of strength and compactness, fundamental for machinery of this type.
Base, column, table and head are the elements that make up the basic structure of the KR-1500 and are therefore made of cast iron.
The sliding of the table on the base takes place on the traditional and tested system of flat guides and prism.
The movement is given by a variable speed gear motor, which acts directly on the ball screw and which allows the table to be moved.
The coupling between the column and the head takes place on dovetail guides, and the vertical displacement is also given by a ball screw.
The large surface of the table and the useful working stroke, combined with the construction characteristics previously described, allow the resurfacing of heads and blocks of large engines.
To allow the processing of very large blocks, it also favors the useful distance between the table top and grinding stones which is a good 800 mm in height.
The KR-1500 also allows the operator to manage the cutting and feed speeds of the table, thus offering greater customization of settings during the grinding operation.
The working potential of the KR-1500 is further extended thanks to the possibility of using both the grinding segments with coolant or the brazed carbide tool supplied.
To meet the demands of the most demanding grinders, the KR-1500 can be further equipped with cutter plate and cartridges for PCD and CBN inserts.
The control panel is positioned on an adjustable arm and easily accessible by the operator who can have access to all the drives.
On the control panel there are:
- 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
