Products Description

RBH adjustable double-edged rough boring tool series covers mainstream machining apertures from φ25 to φ204mm. Adopting a symmetrical double-edge balanced cutting structure, it solves the disadvantages of uneven force and low cutting efficiency of traditional single-edge boring tools. The whole tool is integrally formed of high-strength alloy steel and processed by multi-layer heat hardening and precision grinding, featuring solid structure, excellent impact resistance and deformation resistance, suitable for long-term continuous CNC heavy-duty machining.
Equipped with a high-precision mechanical micro-adjustment structure with clear scales and stable adjustment stroke, it maintains zero gap and no displacement after locking, ensuring consistent aperture dimension in mass production. The optimized open chip groove accelerates heat dissipation and smooth chip removal, reducing workpiece wall scratches and built-up edges. Compatible with various machining centers, CNC boring and milling machines and standard shanks, it is widely used in medium-bore rough boring processes in machinery manufacturing, auto parts, hydraulics, molds and other industries, shortening processing cycles and lowering overall production costs.

Product Feature

Core Performance Upgrade・Stable Cutting & Cost Efficiency

Double-Edge Balanced Cutting Design

The symmetrical double-edge layout counteracts cutting force mutually, greatly reducing cutting vibration. It keeps stable in long overhang machining, effectively avoiding elliptical holes and tool marks to improve roughing quality.

High-Strength & Heavy-Duty Adaptation

Made of special alloy material with hardened surface treatment, balancing hardness and toughness. It is suitable for cutting carbon steel, cast iron and alloy steel, resisting wear and bending under heavy load to extend service life.

Precision Micro-Adjustment & Locking System

With visible external adjustment scales, aperture tuning is simple and intuitive with reliable positioning accuracy. The integrated locking structure ensures tight fitting without loosening or shifting during operation for stable dimension output.

Modular High Compatibility Configuration

The standardized connecting structure quickly matches mainstream CNC shanks without extra adapters. The compact structure adapts flexibly to narrow cavities and dense hole machining scenarios for wide application.

FAQ

Q: Q1: What is the adjustment range of RBH double-edged rough boring tool?

A: A1: The standard boring range is φ25–φ204mm, covering most medium aperture processing needs in machinery, auto parts and mold industries.

Q: Q2: Will double-edge cutting cause excessive load and machine vibration?

A: A2: The symmetrical double-edge design balances radial force with even cutting load. It delivers better shock resistance than single-edge tools and will not cause abnormal vibration with correct parameters.

Q: Q3: Will the adjustment part loosen and cause dimension deviation after long-term mass production?

A: A3: Adopting thickened locking buckle and anti-loosening positioning structure, it provides sufficient clamping force to avoid loosening and ensure long-term dimensional stability in continuous processing.

Q: Q4: Is it suitable for machining hard materials such as stainless steel?

A: A4: The high-strength tool body supports hard cutting. Equipped with special carbide inserts, it can stably process stainless steel, alloy steel and other high-hardness workpieces.

Q: Q5: Is the installation complicated? Does it need to modify machine fixtures?

A: A5: It adopts a universal standard interface, consistent with conventional boring tools. It can be installed directly on existing shanks and fixtures without equipment modification.

Q: Q6: Does this tool have optimized chip removal design to avoid chip jamming?

A: A6: Designed with widened streamlined chip grooves and double-edge split chip removal, it ensures smooth chip discharge, effectively preventing chip accumulation and workpiece scratching.
