AKKO boring heads: precision and reliability for modern metal cutting production.

The Turkish company AKKO, a recognized manufacturer of machine tools and cutting tools, offers a range of boring heads - key elements of the technological chain when processing holes on CNC milling and lathes. These products combine engineering thoughtfulness, compliance with international standards and affordable cost, which makes them in demand at Russian and foreign enterprises.

Purpose and scope of application

AKKO boring heads are designed for:

• Finishing (finishing) of holes with high precision;
• Diameter adjustments after drilling or countersinking;
• Obtaining the specified surface roughness parameters;
• Work with blanks made of steel, cast iron, non-ferrous metals and alloys.

Application areas

• Mechanical engineering (including production of engines and transmissions);
• Aviation and space industry;
• Tool manufacturing;
• Repair and restoration of parts.

Design features

Key design elements ensure the stability and accuracy of the process:

• Cylindrical shank (Weldon) - reliable fixation in the machine spindle.
• COOLANT supply system - effective cooling of the cutting area, reducing tool wear and improving surface quality.
• Precise adjustment of the boring system - the possibility of micrometric adjustment of the machining diameter.
• Rigid fixation with chuck - minimizes vibrations at high cutting speeds.
• Replaceable cartridges - quick replacement of cutting elements without reconfiguring the machine.
