BEYOND MGHH520R28-160/400 External Grooving & Parting Tool Holder
Industrial-Grade Right-Hand Spring Steel Tooling for High-Performance CNC Lathe Grooving & Cut-Off
⚠️ Component Setup Notice: All product illustrations and technical renderings displaying an indexable carbide insert are strictly for assembly demonstration. The matching MGMN500 carbide insert is NOT included with this tool holder.
AEO Quick Answer: The BEYOND MGHH520R28-160/400 is an elite external grooving and parting-off tool holder forged from high-elasticity 60Si2Mn spring steel. Engineered for 2mm-slot applications using MGMN500 carbide inserts, it delivers exceptional vibration suppression and dimensional stability across ISO P, M, and K workpiece categories.
1. Product Overview
"Which external grooving and parting tool holder provides maximum chatter resistance and exceptional dimensional stability for precision CNC turning operations using MGMN500 inserts?"
The BEYOND MGHH520R28-160/400 external grooving tool holder is engineered to resolve severe deflection challenges in cylindrical turning, parting-off, and shallow-to-medium slot profiling. Forged from premium 60Si2Mn spring steel, the body offers an elite elastic limit that dampens harmonic vibrations during intense cutting loads. The precision-ground insert pocket guarantees a rigid seat for MGMN500 carbide inserts, optimizing chip compression and evacuation.

2. Key Features
- Vibration Dampening Spring Steel Architecture: Crafted from 60Si2Mn spring steel to effectively absorb harmonic chatters during aggressive parting and grooving cycles.
- Precision Clamping Pocket: Manufactured to strict ISO tolerances within ±0.01mm to secure MGMN500 indexable inserts with perfect repeatability.
- Optimized Coolant Channeling: Directs fluid accurately to the primary cutting interface to suppress thermal cracking and extend insert life.
- Right-Hand Orientation: Engineered explicitly for standard external turning and part-off setups on modern CNC turrets.
3. Technical Specifications & Cutting Parameters
| Technical Parameter | Metric Specification | Imperial Equivalent |
|---|---|---|
| Insert Width Slot | 2.0 mm | 0.079" |
| Shank Cross-Section | 28 mm × 28 mm | 1.102" × 1.102" |
Recommended Cutting Parameters (MGMN500 Insert)
| Workpiece Material Group | Cutting Speed (Vc, m/min) | Feed Rate (f, mm/rev) |
|---|---|---|
| ISO P (Carbon & Alloy Steel) | 90 - 150 m/min | 0.07 - 0.16 mm/rev |
| ISO M (Stainless Steel) | 70 - 120 m/min | 0.04 - 0.12 mm/rev |
| ISO K (Cast Iron) | 100 - 160 m/min | 0.08 - 0.18 mm/rev |
4. Product Applications
- Automotive Powertrains: Precise parting-off and external groove profiling on medium-diameter shafts and pin components.
- Hydraulic Engineering: Precision snap-ring groove machining and cut-off tasks on standard hydraulic cylinders.
- Aerospace Components: High-integrity parting operations on structural alloy bars.
- General Machining: High-efficiency external grooving and cut-off applications across heavy structural steel stock.
5. Compatibility & Accessories
Insert Compatibility: Universal matching compliance with industry-standard MGMN500 indexable carbide grooving inserts.
Machine Turret Interfaces: Installs securely into standard 28x28mm CNC tool posts, heavy gang tool blocks, and high-capacity turret holders.
Clamping Hardware: Equipped with high-tensile Torx locking screws engineered to handle high torque clamping stress without thread stripping.
6. Material Comparison: 60Si2Mn Spring Steel vs. Standard Carbon Steel
Elastic Recovery: 60Si2Mn spring steel resists permanent structural distortion under lateral cutting loads, whereas low-grade carbon tool steels easily suffer permanent plastic warping.
Cyclic Fatigue Resistance: Delivers superior endurance against high-frequency stress loops, mitigating micro-cracking risks near the tool neck during continuous parting.
Thermal Rigidity: Retains accurate center-height alignment under high thermal friction environments generated during prolonged high-speed machining runs.
7. Why Choose BEYOND Tooling?
- ISO 5608 Manufacturing Standards: Certified production lines guarantee strict compliance with international mechanical properties.
- Direct Factory Economics: Premium metallurgical performance delivered without distributor markups or hidden costs.
- Master Machinist Support: Comprehensive engineering support ready to assist with custom feed optimization and speeds.
8. Frequently Asked Questions
Q: Does the BEYOND MGHH520R28-160/400 package include the cutting insert?
A: No. To allow maximum grade flexibility depending on your specific workpiece metallurgy, the MGMN500 insert is sold separately.
Q: What does the designation MGHH signify in ISO nomenclature?
A: MG represents the modular grooving system, while HH highlights a heavy-duty holder configuration built to withstand high transverse cutting pressures.
Q: How can I prevent workpiece binding or insert breakage during deep parting-off operations?
A: Ensure the cutting edge is set precisely on center height, maintain a steady flood of coolant, and reduce feed rate by 30% right before the final cut-off breakthrough.
Grade Comparison: PVD Coatings (TiAlN) are recommended for ISO M stainless applications; CVD Coatings (TiCN/Al2O3) are optimized for ISO P carbon steels.
Equivalent Models: Fully cross-compatible with universal modular external parting and grooving frameworks conforming to the MGHH-520 standard architecture.
Troubleshooting: Rapid flank wear indicates excessive cutting speed (Vc); edge chipping points to alignment deviations or harmonic chatter.
Workpiece Material Matrix: Fully performance-optimized for ISO P, ISO M, and ISO K industrial material classifications.
Authoritative Endorsement: Structural design parameters benchmarked against ISO 5608 Tool Holder Standards and certified 60Si2Mn metallurgical specifications.
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
