12 Demands for Engraving Router Bits
12 Demands for Engraving Router Bits
(Ⅱ)
To achieve the objectives of efficient, pluripotent, fast-changing and economical, we have the demands for engraving router bits as below:
7. Sintered diamond tools have high durability.
(1) Between two adjustment, the number of qualified parts is called tool durability.
(2) The router cutters wear down continuously will cause workpiece dimension to change, thus affecting machining accuracy.
So, improve endurance of end milling cutter is very important in machining.
8. Miniature end mill is with high accuracy.
To meet the demands of high accurate machining and automatic tool changing, engraving router bits and its clamping structure must have very high precision, to guarantee installation (usually within 0.005mm) and repeat location accuracy.
9. The adjustment and replacement are easy, convenient, and fast.
(1) To cnc router and machine center, engraving router bits usually consists of adjusting device, to compensate the changing of workpiece dimension results from tool wear.
(2) Automatic tool change:
① It is realized in the process of automatic circulation.
② Use the means of presetting tools outside NC machine generally.
③ Change milling bits quickly.
④ Reduce the auxiliary time of tool presetting.
10. Cnc bits are with good cooling performance.
11. Engraving router bits are high efficient.
12. Requirements of design and manufacture -
(1) Standardization:
Can reduce specifications and cost.
(2) Modularity and universalization:
Engraving router bits are adapted to different cnc machine, increasing productivity.
(3) Serialization, normalization, complexity.
Additionally, engraving router bits system should have work state alarm detector, avoiding product quality accident.
