Detailed Solution
Download Solution PDF- धातुकर्म में खरोंचनी का प्रयोग निर्माण के पहले कार्य-वस्तु पर रेखाएँ खींचने के लिए किया जाता है
- खरोंचनी की सूक्ष्मतः टेपर की हुई और सूक्ष्म बिंदु नोक पतली और अधिक परिशुद्ध रेखा खींचती है, साथ ही यह बहुत निकट रेखाएँ खींचने में भी उपयुक्त है
- लेकिन अधिक सूक्ष्म नोक जल्दी घिस जाती है और उसे बार - बार नुकीला करना पड़ता है और यह आसानी से टूट भी जाती है
- इसलिए 12° से 15° डिग्री अधिक उपयुक्त है
