SDJ precision boring head

1. Displacement of 10mm with an error ratio of 0.001

2. Displacement sensitivity unilateral 0.0025

3. Measure the unilateral cutting accuracy variable of 0.005

4. Rotary clearance 0.0255. Single surface roundness (4 times diameter) 0.001

6. Unilateral cutting amount: 0.8mm

7. Insert: TPGH0902

P20 material manufacturing, High seismic performance.

Water outlet is set inside, Cool the boring blade in time.

Sawtooth rail type blade holder, The boring is more rigid.

One side cutting 0.8mm,

Fast and large allowance cutting.

(Conventional EWN boring head ，

The unilateral cutting amount is 0.2mm,

SDJ is （0.8mm）=EWN（0.2mm） × 4）Coarse and fine adjustment scales,

From fast adjustment to accurate adjustment,

It can reduce the use of rough boring head,

Save cost and reduce boring time.Product Instructions

1. Turn the top screw with a wrench, and the screw is loose.

2. Push the top slider to quickly adjust the scale of the rough boring cutter.

3. Rotate the side fine boring dial to fine tune.

4. After setting, turn the set screw to prepare for processing.
