Usage Precautions
Proper Installation
Before installation, thoroughly clean the tool holder's tapered shank, the spindle interface, and the holder's inner bore to ensure they are free of chips, rust, or damage. The boring bar must be inserted along the full length of the tool holder; the overhang length must not exceed three times the boring bar's diameter (3×D) to prevent excessive vibration.
01
Correct Clamping
Use a torque wrench to tighten the clamping screws in accordance with the manufacturer's specifications, avoiding overtightening or insufficient tightening. When installing the boring tool, take care to prevent the cutting edge from scraping violently against the inner surface of the tool holder, thereby avoiding damage to the cutting edge.
02
Safety Precautions
Protective eyewear, ear defenders, and safety gloves must be worn during operation. Avoid contact with rotating components and areas subject to high-pressure coolant spray.
03
Regular Inspection
Prior to each use, inspect the tool holder for dents, excessive wear, or damaged threads; any damaged components must be replaced immediately. Clean and lubricate the holder after use, and store it in a dry environment to prevent corrosion.
04
Prohibited Operations
It is strictly forbidden to clamp any tools or workpieces other than a boring bar. Do not touch the rotating tool holder before the machine has come to a complete stop for inspection.
05
Key Application Areas
Boring tool holder sets are widely utilized in the precision boring operations of equipment such as CNC milling machines and machining centers, serving as a critical accessory for the high-precision machining of parts featuring holes.
In the automotive manufacturing sector, these tools are employed for the high-precision boring of components such as engine blocks and caliper brackets. Furthermore, in the machining of hexagonal rivet holes for new energy vehicles, boring tool holders enable the completion of a single hexagonal hole in just one second-striking an optimal balance between efficiency and precision.
In mold manufacturing, these tools are utilized for high-precision boring operations on guide post holes and insert cavities within mold bases, thereby ensuring dimensional stability. In the precision machinery and hydraulics sectors, they are employed to machine components with stringent dimensional accuracy requirements-such as bearing housings and hydraulic parts. Furthermore, the processing of micro-components finds application in fields ranging from electronic devices and optical equipment to medical instruments; notably, certain small-diameter boring toolholders are capable of achieving a minimum machining diameter of just ø4mm.
Moreover, this tool set is adaptable to a diverse array of machining scenarios-including internal boring, back boring, and external boring-effectively meeting the full spectrum of requirements from roughing through to finishing operations.
