Sharpening of cutting tools is a common problem prolonged use of the tool. Even tool hard steel gradually loses its productive properties and requires sharpening for extending the period of application and reducing the cost of getting a new.
Our company for the solution of this problem provides a universal grinding machine 3Е642. The machine performs a grinding or lapping of the cutting tool made of hard alloy, tool steel or or mineral ceramic. Advantage of the tools made of hard metal-ceramic joints, unlike high-speed steel, high content of tungsten and high heat resistance. Grinding is performed with abrasive, diamond and grinding wheels.
In addition, the grinding machine performs the following work:
- external and internal circular grinding;
- flat grinding.
The defining characteristics of the grinding machine 3Е642:
- large metallurgical performance in a compact size;
- no wrong with the table drive from the flywheel;
- cast frame to reduce vibrations when machining the workpiece, increase machining accuracy;
- the permissibility of the installation on the machine the suction dust;
- the ability to resupply a large list of additional equipment required to implement the technical specifications, in particular for fixing workpieces;
- installation on the machine sine plate;
- reversal of the motor ofthe grinding wheel in the direction opposite the spindle, allows weighty toaccelerate changeover, increase technological capabilities.
An important part of the machine 3Е642 is the ability to set it to the widest number of devices that allows you to handle almost any cutting tool.Video Universal Tools And Cutter Grinder 3Е642
