Easy NC Programming
Easy programming by simply offsetting the centers between the machine spindle and hole.
Eccentric grinding process
Under the premise of ensuring rigidity, the use of eccentric grinding process can effectively avoid the empty.
Well designed
Precision crafted, screw off-set design, blades are mounted without gaps for enhanced rigidity. Avoid blade loss caused by vibration, better machining effect.
Eccentric back spot face hole
Solve the processing pain points, processing the back countersunk holes do not need to turn the surface, greatly improving processing efficiency
Rust and corrosion prevention
Electroplating treatment, so that the product is corrosion-resistant, wear-resistant, oxidation-resistant, the blade and the cutter bar close fit, high tightness, comprehensive precision better
Side fastening clamping method
The surface of the toolholder is milled parallel and flat, which makes the clamping force stronger and less slippery during machining.
Replaceable standard inserts
Interchangeable CCMT inserts reduce processing costs
Clear specification branding
Laser engraving for clearer specification branding
