The Cutting Holder is one of the most fundamental components in CNC machining and lathe operations. Its primary function is to securely clamp and position the cutting insert, providing a rigid and stable base for material removal. Without a reliable cutting holder, even the most advanced inserts cannot deliver consistent performance. Cutting holders are used for a wide variety of machining processes, including external turning, internal boring, threading, grooving, and parting. By ensuring correct insert positioning and minimizing vibration, cutting holders allow manufacturers to achieve accurate dimensions, superior surface finishes, and efficient machining cycles. They are indispensable tools for both heavy-duty roughing and fine finishing operations.
Rigid Construction: Made from high-grade alloy steel with heat treatment for maximum durability and wear resistance.
Precision Design: Ground clamping surfaces ensure accurate insert positioning and repeatability within tight tolerances.
Vibration Control: Engineered geometries reduce chatter, ensuring smoother cutting performance and longer tool life.
Versatile Compatibility: Supports a wide range of insert types and geometries, including CNMG, DNMG, SNMG, TNMG, VNMG, and more.
Corrosion Resistance: Coated surfaces (such as black oxide or nickel plating) extend service life in various machining environments.
Quick Setup: Many models feature easy insert replacement systems, reducing downtime and simplifying maintenance.
With these features, cutting holders play a crucial role in achieving consistent performance, cost efficiency, and long-term reliability in machining operations.
Shank Sizes: Common sizes include 16 mm, 20 mm, 25 mm, 32 mm, and 40 mm, depending on machine type and cutting depth.
Insert Types: Compatible with multiple ISO-standard inserts for roughing, finishing, threading, and grooving.
Holder Types: External turning holders, boring holders, threading holders, grooving and parting holders, profiling holders.
Clamping System: Mechanical clamping with screws, wedges, or lever systems for secure insert fixation.
Precision Tolerance: Typically ≤0.01 mm runout, ensuring dimensional stability in repeated use.
Surface Treatments: Black oxide or anti-rust coatings for longer operational lifespan.
These specifications enable cutting holders to adapt to different materials, cutting forces, and machining strategies, from heavy steel cutting to precision machining of non-ferrous alloys.
Proper Installation: Ensure the cutting holder shank is mounted firmly and aligned with the machine’s tool post or turret.
Insert Selection: Match the insert geometry, grade, and coating to the workpiece material and machining conditions.
Secure Clamping: Tighten inserts with the correct torque, as improper tightening can lead to insert movement or tool failure.
Cutting Parameters: Use cutting speeds, feeds, and depths of cut recommended for both the insert and holder to prevent overloading.
Maintenance: After each use, clean the insert pocket and clamping area to remove chips, oil, or coolant residues. Regularly inspect for wear and replace damaged holders.
By following these steps, cutting holders deliver stable machining performance, extended insert life, and minimized downtime.
Automotive: For engine shafts, transmission parts, and mass production components where speed and consistency are critical.
Aerospace: For precision turning of turbine blades, structural components, and alloy parts requiring high accuracy.
Heavy Machinery: For large-scale turning and boring of equipment parts under heavy cutting loads.
Medical Equipment: For small, high-precision parts such as implants and surgical instruments.
General Precision Engineering: For machining of components in electronics, robotics, and custom manufacturing.
