Product catalog summary

Milling Parameters Overview
The document provides detailed milling parameters for SikaBlock® model and tooling boards, including key symbols and conversion formulas for calculating parameters such as cutting width, diameter, feedrate per tooth, cutting speed, cutting depth, revolutions, feed rate, and number of teeth.

Milling Steps and Parameters
Seven milling steps are outlined, each with specific parameters for roughing and finishing processes:

Step 1: Roughing with a cutter head Ø 42 mm, cutting speed 500 m/min, cutting depth 5.0 mm.
Step 2: Roughing with WPB Ø 20 mm, cutting speed 500 m/min, cutting depth 2.5 mm.
Step 3: Roughing with WPR Ø 12 mm, cutting speed 600 m/min, cutting depth 2.0 mm.
Step 4: Roughing with WPR Ø 6 mm, cutting speed 300 m/min, cutting depth 0.5 mm.
Step 5: Finishing flat areas with WPB Ø 8 mm, cutting speed 400 m/min, cutting depth 0.3 mm.
Step 6: Roughing and optimizing with WPR Ø 8 mm, cutting speed 400 m/min, cutting depth 0.15 mm.
Step 7: Finishing rest material shapes with VHM Ø 4 mm, cutting speed 200 m/min, cutting depth 0.1 mm.

Processing Guidelines
For SikaBlock® model boards, acclimatization to 18–25°C before machining is essential. Machining can be done manually or with machines using sawing, milling, or drilling. Bonding areas must be clean and free of dust, grease, or oil, with specific adhesives like Biresin® Foam Adhesive recommended.

Model and Tooling Boards Characteristics
The document compares different SikaBlock® model boards (e.g., M80, M150, M330) and tooling boards (e.g., M940, M960), highlighting their density, color, characteristics, and applications. For example, SikaBlock® M80 is noted for its fine, dense surface and low dust formation, suitable for styling models and design studies.

Adhesives and Fillers
Details on adhesives and fillers include mixing ratios, pot life, and setting times. Biresin® Foam Adhesive is a 1-component adhesive with a 10-minute open time and a setting time of 6–8 hours.

Physical Data
Approximate physical data such as Shore-hardness, flexural strength, and coefficient of thermal expansion for various SikaBlock® boards are included to aid in selecting the appropriate material for specific applications.

Tool Specifications
The document lists milling tools with specifications such as diameter, number of teeth, radius, cutting speed, revolutions per minute, feed rate per tooth, overall feed rate, cutting depth, and line spacing, crucial for selecting the appropriate tool for specific milling tasks.

Material-Specific Instructions
Different SikaBlock® materials, such as M970, M960, M1000/M1050, and M980, have tailored milling parameters and processing instructions, including acclimatization, machining methods, and bonding recommendations.
