I'm looking to build a very small and precise as possible CNC mill to brass and steel.

Would this X,Y set up be a good place to start?

I have attached a photo and the specs are below.

Parker 404XR X/Y Stage Assembly:
Parker 404100XRMP Linear Actuators
16mm dia. Precision Ground Ballscrew,
Proximity Sensors Limit / Homing,
IMS MDrive17 Stepper Motors with Built-in Driver & Encoder
+12vdc to +48vdc Input Voltage
512-line Encoder (2,048 edges per rev)

The actuators are model 404100XRMP with a 100mm rated stroke length, but the max stroke length is actually about 120mm (4-3/4").
The ballscrews are precision ground 16mm dia. x 5mm pitch and the rails are model Hiwin MGNR9H with two bearings on each rail.
The actuators have (3) proximity sensors (Limit / Homing switches) that are mounted to the side of the actuators in a protective aluminum housing with clear plastic top cover & 5-pin connector.

The 404XRMP actuators are extremely accurate ('P' = 'Precision' model), they have a repeatability of 1.3um (1.3microns = 0.00005")
Length of actuator (not including motor mount or motor) is 12", overall length of actuator with motor & mount is 17-1/2"
Parker model# 404100XRMP-D2H3L2C25M37E1B1R1P1
The motors are IMS MDrive 17 steppers with built-in driver and an internal 512-line encoder. Output shaft is 5mm diameter with flat.
IMS MDrive17 motor Model# MDI3CRL17B4-EQ

They look to be pretty light duty.
NEMA 17 steppers

Encoders only 512 count - this is very low

Thank you!
