3D scanner: 0.05mm

Cylinder

Replaceable clip head

Block

More accurate

linear movement:0.0002mm;

rotational movement: 0.00072degree

linear movement:0.0002mm;

deformation of the part: almost negligible

Smaller three jaw chuck

rotational movement: 0.00072degree

  • Hole angle<5°

maximum moving time: 3.6s per hole

Overall Layout

3D printed support

Flexible Clamping System

maximum drill time: 5s per hole

  • Maximum total time: 8.6s per hole

Improved Design

  • Scanning time: 2 min

Machine without the case

For 20 holes: 4min52s<5min

Check!Check!

Compared with thrust bearing

Handles larger axial and radial load

Considerable larger bending moment

Tool length switch

All major parts redesigned

<25kg

Total Weight

New Linear guide

Handles bending moment

Components : Designed & purchased

Initial position switch

Dustproof cap

1. New components purchased

Increased reliability

2. lightweight design

580

x-direction guide:self-design

space: save 200mm

Table-Class!

Basement

New drill motor

1. Less volume

2. More simple structure

A substantial weight reduction compared to a solid basement

3. Easier to control

4. Torque almost constant in a large range of rpm
