Method for testing cutting performance of diamond saw blade, diamond grinding wheel and diamond drill bit

A method for testing cutting performance of a diamond saw blade, comprising steps of:

• (1) obtaining a set load parameter value, particularly comprising steps of:
• controlling a feed amount of the diamond saw blade;
• finding out a load value K corresponding to a maximum feed amount of the diamond saw blade on a cutting object;
• and setting M=0.70K-0.85K, wherein M is the set load parameter value;
• (2) during cutting, controlling a cutting load value of the diamond saw blade to be 0.90M-1.1M through a servo system;
• and
• (3) according to a cutting length and a cutting time, calculating a sharpness of the diamond saw blade;
• and, according to the cutting length and a consumed tooth height of the diamond saw blade during cutting, calculating a working life of the diamond saw blade.

A method for testing grinding performance of a diamond grinding wheel, comprising steps of:

• (1) obtaining a set load parameter value, particularly comprising steps of:
• controlling a feed amount of the diamond grinding wheel;
• finding out a load value K corresponding to a maximum feed amount of the diamond grinding wheel on a grinding object;
• and setting M=0.70K-0.85K, wherein M is the set load parameter value;
• (2) during grinding, controlling a grinding load value of the diamond grinding wheel to be 0.90M-1.1M through a servo system;
• and
• (3) according to a grinding volume and a grinding time of the grinding object, obtaining a grinding sharpness of the diamond grinding wheel;
• and, according to the grinding volume of the grinding object and a consumption value of a tooth height of the grinding wheel after grinding, obtaining a working life of the diamond grinding wheel.

A method for testing drilling performance of a diamond drill bit, comprising steps of:

• (1) obtaining a set load parameter value, particularly comprising steps of:
• controlling a feed amount of the diamond drill bit;
• finding out a load value K corresponding to a maximum feed amount of the diamond drill bit on a drilling object;
• and setting M=0.70K-0.85K, wherein M is the set load parameter value;
• (2) during drilling, controlling a drilling load value of the diamond drill bit to be 0.90M-1.1M through a servo system;
• and
• (3) according to a drilling time, a tooth height consumption and a drilling depth, obtaining the performance of the diamond drill bit.
