Specification: Name: Mechanical Edge Finder Material: Carbon Steel Big End: 20mm/0.8inch Small End: 10mm/0.4inch Total Length: 90mm/3.5inch Quantity: 1pc Mechanical Centering Bar Features: 1. A 10 straight rod can be mounted on a cutter chuck or drill chuck. 2. Offset the sizer by 0.5mm by lightly pressing the side of the sizer with a finger. 3. To rotate it at 400-600RPM. 4. The spring force is small enough to prevent the small cutter or drill bit from breaking. 5. Establish contact between the measuring stand and the end face of the workpiece, by touching and moving it little by little, it will reach the full contact state, the measuring stand will not vibrate, just like a static contact state, if an external force is applied at this time, the measuring stand will be moved out of position, the starting point of sliding here is the required reference position. 6. The final position of the workpiece itself is the coordinate position with a radius of 5 mm of the measuring subsystem Precautions for using the offset edge detector. 1. Do not use the edge detector to bend or drag barely, otherwise it will affect the accuracy. Do not adhere foreign matter or fine dust to the sliding end surfaces. 3. Do not exceed 600RPM during measurement. 4. The offset edge detector cannot be used on horizontal type machines. Product Description This high-precision mechanical rotary measuring tool is suitable for traditional milling machines and integrated machining machines. The non-magnetic edge finder is placed in a storage box. The mechanical rotary measurement has no clamping error, and the repeated measurement accuracy can reach 0.005 mm. A 4 mm probe specially designed for measuring small openings and narrow grooves. The rotating part of the lower end of the mechanical edge finder is of anti-magnetic design. luckymeet
