Frequently Asked Questions
Q
What types of shims are available for turning tool holders?
We offer shims in five figure types (A, B, C, D, and E) to suit a wide range of turning tool holder configurations. Each figure type corresponds to a specific geometry, with multiple specifications available covering different dimensions of d, h, and L to match your tooling requirements precisely.
Q
What is the difference between the N-type and Q-type clamping screws for grooving holders?
The N-type clamping screws (e.g., M4*6N, M5*12N) are designed for standard grooving holder clamping applications, while the Q-type screws (e.g., M4*14Q, M6*20Q) feature a different thread engagement geometry suited for specific grooving holder designs. Please refer to the dimension table to select the correct type based on your holder's bore and thread specifications.
Q
How do I select the correct insert screw size for my cutting insert?
Insert screw selection depends on the insert pocket thread size (d1), outer diameter (D), total length (L), and the cone angle (a). Match the thread specification of your insert pocket (e.g., M2.5*0.45, M3.5*0.6) with the corresponding insert screw in the table, and verify the cone angle (50°, 55°, or 60°) matches your tool holder's design requirement.
Q
What material are the center screws and clamping screws made from?
Our center screws and clamping screws are manufactured from high-strength alloy steel with precision heat treatment to ensure durability, corrosion resistance, and consistent clamping force. This ensures reliable performance under demanding turning and grooving operations.
Q
Are the clamps and C rings compatible with standard W-type turning tool holders?
Yes. The C ring (KH540) is specifically designed for W-type turning tool holders, providing a secure locking function. The clamps listed (HL-series, MY-series, WT16, YW08) are engineered to be compatible with common industry-standard turning tool holder designs. Please verify the D, d1, L, and H dimensions against your holder specifications before ordering.
Q
Can custom specifications be provided for shims, screws, and clamps?
Yes, we support custom specifications for shims, center screws, clamping screws, clamps, and related turning tool holder accessories. If your application requires dimensions beyond the standard range listed in our catalog, please contact us with your technical drawings or dimensional requirements and our engineering team will provide a tailored solution.
