EMR Indexable Milling Tool Holder

About the product

1.The EMR milling tool holder is suitable for a variety of machining tasks, including surface, U-groove, side and slotting operations.

2.It is made of high-quality 42CrMo steel with a hardness of HRC48, which is durable and low resistance.

3.Its large chip space ensures efficient chip evacuation and maintains performance even in harsh conditions. The off-set screw design enhances the fit with the milling tool, making it ideal for heavy cutting, large rotations and high feed rates.

4.This indexable tool holder is a reliable choice for precision and power in milling applications.

Material & Construction

• Core Material: Forged from high-quality 42CrMo alloy steel, a material renowned for its high tensile strength (≥1,000 MPa) and impact resistance. The holder undergoes quenching and tempering treatment to achieve a hardness of HRC48—striking a balance between rigidity (to resist bending during heavy cutting) and toughness (to avoid cracking under vibration).

• Surface Treatment: Features a black oxide or zinc-nickel coating that provides corrosion resistance (withstanding coolant exposure in wet machining) and reduces friction between the holder and spindle interface, minimizing wear over time.

• Precision Machining: Critical surfaces (spindle taper, tool clamping seat) are ground to ±0.002mm tolerance to ensure low runout (≤0.003mm at the tool tip), a key factor in maintaining machining precision.

Key Features

1. Versatile Machining Compatibility
   Engineered to handle multiple milling tasks:

• Surface Milling: Achieves flat, smooth workpiece surfaces (Ra ≤ 1.6μm) for components like automotive engine covers.

• U-Groove & Slotting: Its rigid structure supports deep slotting (up to 5× tool diameter) and precise U-groove machining, ideal for industrial brackets or mold frames.

• Side Milling: Maintains stable cutting when machining vertical edges of parts, ensuring consistent wall thickness (tolerance ±0.005mm).

• Off-Set Screw Clamping: The off-set screw design applies uniform pressure to the indexable insert, enhancing grip strength by 30% vs. standard holders. This ensures the insert stays securely in place during heavy cutting (up to 8,000 N cutting force), high spindle speeds (2,000–8,000 RPM), and high feed rates (0.3–0.8 mm/tooth).

• Large Chip Space: Generous chip evacuation channels prevent clogging—even when machining ductile materials (e.g., aluminum, low-carbon steel)—reducing heat buildup and avoiding chip-induced scratches on the workpiece.

Applications

• Target Industries:

• Automotive: Machining engine blocks, transmission housings, and chassis components (heavy-duty roughing and semi-finishing).

• Heavy Machinery: Manufacturing large structural parts (e.g., hydraulic cylinder barrels, gear blanks) that require deep slotting or surface milling.

• Mold & Die: Semi-finishing mold cavities and U-grooves in tool steel (e.g., P20, H13) for plastic injection molds.

• Materials Handled: Carbon steel (Q235, 45#), alloy steel (40Cr, 42CrMo), stainless steel (304, 316), aluminum (6061, 7075), and cast iron (HT200).

Compatible Machines

• CNC Milling Machines: Fanuc Robodrill, Haas VF-series, Mazak VTC, and DMG MORI DMC (supports BT40, BT50, or CAT40 spindle interfaces).

• Vertical Machining Centers (VMCs): Ideal for medium-to-large part machining, leveraging the holder’s rigidity for heavy cuts.

• Horizontal Machining Centers (HMCs): Used for high-volume production of symmetric parts (e.g., automotive brackets), where the holder’s chip control and stability prevent downtime.

Performance & Lifespan

• Recommended Operating Parameters:

• Spindle Speed: 2,000–8,000 RPM (varies by workpiece material; lower speeds for cast iron, higher for aluminum).

• Cutting Force Capacity: Up to 8,000 N (suitable for heavy roughing).

• Runout: ≤0.003mm (ensures insert edge wears evenly, extending insert life by 25%).

• Service Life:

• 7–10 years of daily use (8–12 hours/day) in standard machining environments.

• Reduced to 5–7 years if used primarily for abrasive materials (e.g., cast iron with sand inclusions) or without regular maintenance.

• Maintenance: Clean the spindle taper and clamping screw after each use; lubricate the screw quarterly to prevent seizing; store in a dry, dust-free case to avoid corrosion.
