Industry-Standard Texture Reference:Matches common EDM texture scales used in mold making. Provides consistent reference points for surface evaluation, helping you make reliable finish judgments during production inspection. Durable Alloy Construction:Crafted from high-hardness alloy substrate with precision machining. Resists wear, scratches, and corrosion in workshop environments, staying readable for daily industrial use. Dual Inspection Method:Supports both visual and tactile comparison for quick assessment. Lets you evaluate finishes without extra equipment, speeding up quality checks on the shop floor. Multiple Roughness Grades:Includes a range of texture specimens from fine to coarse. Covers typical EDM and textured mold surface requirements, accommodating various mold types and specifications. Uniformly Calibrated Specimens:Each sample undergoes consistent processing and verification. Delivers stable texture depth and roughness values, supporting repeatable comparisons for quality assurance.
