Product catalog summary

Company Overview: EMUGE, part of the EMUGE-FRANKEN group, specializes in precision tools for thread production and clamping of tools and workpieces. Their product range includes taps, cold-forming taps, thread milling cutters, twist drills, dies, and thread rolls, all designed to enhance productivity and quality.

Product Lines: EMUGE offers a comprehensive range of solid carbide twist drills under the EF-Drill brand, categorized into four main product lines: EF-Drill Micro, EF-Drill, EF-Drill Modular, and EF-Drill C. Each line is tailored for specific applications, with varying diameter ranges and features such as internal cooling and specialized coatings.

EF-Drill Micro: Designed for small drill holes with a diameter range of 0.75 to 3.00 mm, featuring internal cooling and TIALN-T99 coating, suitable for ISO material groups P, M, K, N, S.

EF-Drill: Available in STEEL, VA, GG, and HCUT geometries, with a diameter range of 2.80 to 20.00 mm, offering both external and internal cooling options, and suitable for various ISO material groups.

EF-Drill Modular: Features a modular design with exchangeable cutting heads, covering a diameter range of 14.00 to 32.00 mm, providing flexibility and cost efficiency.

EF-Drill C: A chamfer drill with a diameter range of 2.80 to 15.50 mm, designed for economical production by combining drilling and chamfering in one step.

Technical Specifications: The catalogue provides detailed specifications for each drill type, including tool features, application areas, and recommended coolant-lubricants. The drills are designed to offer high machining volumes and excellent guiding properties, especially in challenging workpiece conditions.

Ordering and Product Information: The document includes an article code system for easy identification and ordering of drills, along with a comprehensive index and technical information section.

Overview: This document provides technical specifications and recommendations for cutting speeds and feed rates for various materials and drill types. It includes detailed tables with cutting speed (vc) and feed per revolution (f) values for different drill diameters and materials.

Specifications: The document outlines cutting speeds and feed rates for different materials such as steel, stainless steel (VA), cast iron (GG), and others. It provides minimum, recommended, and maximum values for each material and drill diameter.

Procedures: For optimal workpiece conditions and high-performance machine tools, high cutting speeds with reduced feed values are recommended. For machines with lower spindle speeds, lower cutting speeds with higher feed values should be used.

Recommendations: For EF-Drill-STEEL 8 x D, preparatory centering with a pilot drill is advised, and the recommended feed per revolution should be reduced by 15%.

Key Data from Tables: The tables provide cutting speed and feed per revolution values for drill diameters ranging from 3 mm to 20 mm. Each material type has specific values, indicating the flexibility required based on machine capability and material properties.

Critical Information: The bold printed values in the tables are recommended for stable conditions and high-performance tools. Adjustments in cutting speed and feed rate are necessary based on machine capabilities and material conditions.

Specifications and Tools: T-handle and Allen wrenches are specified for clamping and adjusting screws, with dimensions and tool identifications provided. Hydraulic expansion chucks for straight shanks according to DIN 6535 HA are detailed, including dimensions and tool identifications for SK 40 and SK 50.

Service Options: Services include replacing spare parts of the clamping system, adjusting expansion rates, and checking torque and concentricity.

Technical Information:

Regrinding and Recoating Service: Ensures restoration of original tool geometry and coating, with a turnaround of 2-3 weeks.
Typical Chip Forms: Various chip types are described, including start-of-drilling, optimal drilling, and drill-through chips, with notes on space requirements and potential issues.
Tool Clamping: Different clamping methods are discussed, including collet holders, hydraulic expansion chucks, and shrink-fit chucks, with emphasis on concentricity and vibration reduction.
Workpiece Clamping: Proper support and reduced feed for thin-walled workpieces are recommended to prevent bending stress.
Coolant Supply: Internal cooling is preferred for drill depths over 2 x D, with specific recommendations for coolant supply.
Point Angle: The influence of point angles on drilling performance is discussed, with recommendations for centering and pilot holes.

Special Drill Designs: Emuge offers custom solutions for drilling tools, including step drills and multi-tooth tools, tailored to customer needs.

Technical Specifications: The document provides detailed specifications for the EF-Drill Micro, including recommended coolant-lubricant pressures and flow rates for various twist drill diameters ranging from 1 mm to 3 mm. The pressure range is specified in bars, and the flow rate in liters per minute.

Assembly Instructions: Instructions for assembling the drill head into the holder are provided. This includes inserting and tightening screws with recommended torque values, which vary based on the size of the insert seat.

Machining Conditions: Guidelines for machining conditions are outlined, emphasizing the preference for internal cooling and specifying a recommended coolant-lubricant pressure of over 20 bar. The document also notes the maximum allowable slant for entry and exit, axle offset, and run-out.

Problems and Solutions in Drilling: The document identifies common drilling problems such as excessive wear, built-up edges, and chipping. It lists possible causes like excessive machining times, high temperatures, and unstable clamping, along with solutions such as increasing coolant volume, using lubricants with higher oil content, and reducing cutting speed.

Technical Questionnaire: A technical questionnaire is included for solid carbide twist drills, requesting information about the company, contact details, drilled hole specifications, machine details, and previous tools used. This section aims to gather comprehensive data for tool recommendations and performance evaluation.
