GSX MILL SLOT

Product catalog summary

Product Overview

The document presents the GSX MILL SLOT, a high-performance carbide coated end mill designed for continuous processing from drilling to contour milling and grooving. It features a unique three-flute design enabling efficient hole and pocket machining with a single tool, suitable even for small machining centers.

Key Features

Three-flute design: Allows seamless transition from drilling to slotting and contour milling.
New GSX coating: Enhances lubricity and high-temperature hardness, improving chip evacuation and tool life.
Optimized groove shape: Minimizes vibration and burr formation, especially effective on thin or low-rigidity workpieces.
High efficiency on small machines: Stable cutting forces enable high productivity on small spindle machining centers.

Performance Comparison

Comparative data shows the GSX MILL SLOT produces less corner wear and burr height than competitor products, with burr height reduced to less than one-third.

Applications

Ideal for machining structural steels (SS400), carbon steels, cast irons, alloy steels, pre-hardened steels, hardened steels (up to 50HRC), stainless steels (SUS304, SUS316), nickel alloys, and titanium alloys.

Tolerances and Geometry

Diameter tolerance varies by size:
- Up to 3 mm: 0 to -0.015 mm
- 3 to 12 mm: 0 to -0.02 mm
- Above 12 mm: 0 to -0.03 mm
Shank diameter tolerance: h6
Helix angle: 40°

Recommended Cutting Conditions

Cutting parameters are provided for various work materials including structural steels, carbon steels, alloy steels, hardened steels, stainless steels, nickel alloys, and titanium alloys. Parameters include spindle speed (rpm) and feed rate (mm/min) for side milling, grooving, and slotting operations with different depths of cut and radial engagement.

Example for side milling with diameter 1 mm on structural steel: 19,600 rpm and 300 mm/min feed.

Usage Guidelines and Recommendations

Adjust cutting conditions if vibration or abnormal noise occurs.
If machine maximum speed is below recommended, use max speed and reduce feed proportionally.
Use rigid, high-precision machines and tool holders for stable machining.
Use air blow for dry machining.
Use wet machining for stainless steels, nickel alloys, and titanium alloys.
For drilling stainless steels, nickel alloys, and titanium alloys, use step drilling with 0.1D increments.

Catalog excerpts

It is most suitable for into grooving continuously from slotting. It is released in a short type. GS MILL SLOT is stocked in the regular cutting length. Process from drilling to Contour milling Consecutively This endmill having designed originally three flutes can do processing from drilling to contour milling consecutively. Even With Small machine high efficient processing Fluctuation of cutting force is small, and can do high efficiency processing in small spindle machining center. Minimizes fluttering and burr It optimizes ditch shape, and even low hardness and low clamp power such as a sheet restrain vibration and burr. Chip removal is Well Stability processing It is superior to lubricity and hot hardness by new GSX coating, and realize good chip removal and long tool life.
