High Precision Er Milling Collet Sets Er Collet Chuck Er20 Spring Collet
Material:SUJ2 High-carbon bearing steel (After heat treatment, it has rigid hardness and toughness, better grinding quality, good flexibility and longer using life span).
HRC: 46°; Taper: 8°; Surface roughness: within RZ2.5.
Chucking range:ER8,ER11=0.5mm;ER16, ER20, 25, 32, 40=1mm, but if the internal hole is less than 2.5mm, the chucking range will be 0.5mm.
The internal hole is manufactured by precise honing.
The concentricity is totally examined according to DIN norm. There're three kinds of classed for precision: General class.
0.02mm; A class 0.01mm and UP class 0.005mm (UP class is recommended to be used with HSP clamping nut, it will have better stability).
The collet mainly used for the cutting tools like drill, taps, mills and teamers etc. Also it has flexibility and can be applied widely and variably

1. Good chip control & perfect turning surface
Provides perfect turning surface of the workpiece .Excellent and reasonable Chipbreaker design, removing the chips smoothly and taking away the heat of the rubs of the workpiece.

2. CVD coating ensures the high wear resistance
The layer of the CVD coating with the thickness around 8um-20um which guaranteed the high wear resistance.

3. Less tool breakage, cost down of each component
Saving costs and reducing the cost of each component to increase the profits .The high wear resistance makes the long tool life of the carbide inserts, which means you could saving more budget on purchasing the inserts.

4. Long tool life, higher production.
Long tool life means you need less time changing the inserts while machining. A reliable and safe performance every time.

 

Customer's case: 

1. Flank Wear
-Workpiece material contains high hardness chemical elements (tool steel, die steel)
Increase cutting speed if abnormal flank wear is caused by a very slow cutting speed.
Solution: Reduce cutting speed or feed rate or use more wear resistant grade

2. Crater Wear
-Workpiece material contains high hardness chemical elements
Solution: Reduce cutting speed or feed rate or use more wear resistant grade

3. Cracking
-Excessive feed rates when interrupted cutting
Solution: Reduce feed rate, Use tougher grade

 

Technical support and after-sale service:

1. Recommending more suitable processing parameters.
2. According to the workpiece design, material and CNC machine
scheme.
3. We can offer together with tool holder.
