PFERD HM milling cutter SPG 1225/8 Z4 21122748

Pointed arch-shaped milling cutter according to DIN 8032 with teeth according to DIN 8033, flattened tip. - High cutting performance through optimal coordination of hard metal, geometry and toothing. Universally applicable on almost all materials. Reduced wear on the tool drive through impact-free work without chatter marks thanks to precise concentricity. Economical cutting due to long service life - Deburring, machining contours, chamfering/rounding edges, milling in preparation for build-up welding, preparation/leveling of weld seams, cleaning cast iron, changing geometries. Optimum speed and performance of the tool drive (compressed air, electric, flexible shaft) are prerequisites for the economical use of hard metal burrs. Use the highest possible speed within the recommended speed/cutting speed ranges. For low material cutting (deburring, chamfering, light surface processing), the speed can be increased by up to 100%. Pay particular attention to the speed recommendations for materials with poor heat conductivity such as stainless steel (INOX), titanium alloys, etc. in order not to damage the tool. Blue discoloration of the shaft and tool must be avoided. Only use clamping systems/drives with no play. Knocking and rattling of the tools lead to premature wear. Do not select the clamping length of the milling cutter too small. Rule: Minimum clamping length 2/3 of the shaft length. For the economical use of milling cutters with a shaft diameter of 6 mm or more, a drive power of 300–500 watts is required in the upper rpm/cutting speed range. When using milling cutters with coarse teeth (e.g. ALU teeth), even higher drive powers of 500 watts or more are advantageous. The circumference of the milling cutter in contact with the workpiece must not be more than 30% of the total circumference. Failure to observe this will lead to unsteady milling behavior and possibly tooth breakage. If this cannot be avoided, we recommend the TOUGH and TOUGH-S teeth. Milling cutters with HICOAT® coating are particularly suitable for machining materials that are prone to greasing. Alternatively, use cutting oil, grease, petroleum or similar to avoid clogging the teeth. Milling cutters are usually used in the opposite direction or in a pendulum motion. Move the tool quickly over the workpiece in the same direction to produce fine surfaces.
