CRA901 CNC Router Rotary Indexer 4th Axis A 100:1 with 100 Chuck 86 Stepper Motor Gapless Harmonic Gearbox | Инструменты

Package includes:

1 x CNC Router Rotary Indexer

1 x Anti-claw pair

1 x wrench

Description:

This Rotary Indexer could be used for CNC milling machine based on wave (harmonic) gearbox. The main advantages over other types of gearboxes are a large gear ratio, lack of play, and reliable design.

The low location of the lathe chuck allows you to use the device in machines with little movement along the Z axis.

Model:

CRA901-A: with 3-jaw 100MM chuck

CRA901-B: with 4-jaw 100MM chuck

CRA901-C: Just is frame without chuck.

4th Axis Pulse Equivalent Setting:

Mach3 System Settings

Number of pulses of 1 Degree

(number of pulses of Motor/lap* micro-stepping Subdivision of Drive * reduction ratio)/360 degree

Example:

2-phase Nema23 Motor

micro-stepping ubdivision:16

Reduction ratio:50

(200×16×50)÷360=444.44444444

Weihong Card System Settings

The angle of one-pulse

360 degree/( number of pulses of Motor/lap* micro-stepping Subdivision of Drive * reduction ratio)

Example:

2-phase Nema23 Motor

Micro-stepping Subdivision: 16

Reduction Ratio:50

360÷(200×16×50)=0.00225

The replace algorithm of X or Y Axis:

Perimeter/ (number of pulses of Motor/lap* micro-stepping levels of Drive * reduction ratio)
