amatérský soustruh
závity dělá krokový motor řízený (výměnným) kotoučkem na vřetenu
běžné posuvy 2x 555 generátor pulzů
DETAILS:
Between Centers: 750 mm. (easy to extend).
Swing: 450 mm.
Center height: 185 mm.
Chuck: 6".
Chuckspeed: Min.150 rpm, Max. 471 rpm.
Cross slide: adjusting manual.
Headstock: (main) Tapered roller bearings 2 x 32013, (End) Pillow Block ball bearing P210.
Tailstock: Centre MK 4.
Compound: Also used as crossslide, Turnable 90 degree.
Chuck speed reduction: With gearbox Suzuki sj410 (one low speed reverse).
Thread Sizes: M 1.00 , 1.25, 1.50, 1.75, 2.00, 2.50, 3.00 Left and right. (Any other pitch possible by changing plastic encoder disk diameter).
Leadscrew: driven by stepping motor.
Steppingmotor: SANYO DENKI 103-845-6742(1). (34 Frame)
Steppingmotor drive: GAC 03.
Encoder: EL58C2500Z5L, 2500 ppr.
Ratio Leadscrew /steppingmotor: 2 :1 (using T-Belt, cam and crankshaft gear from Suzuki sj410 engine).
Carriage replacement by one step: 0.0037 mm.
Feed cutting speed: Variable with 2 pulse generators (555), two directions, Fast return or both directions slow.
Threadmaking: Leadscrew speed in combination with encoder counter setting and encoder disk diameter.
Counter/Divider (Lead screw speed control): one 4017 decade counter with step switch (on panel) 9 speeds.
Powersupply: 45 Vac / 5, 12, 24Vdc.
Auto Reset Sys. (threading): Leadscrew starts running if chuck and leadscrew are at home position.
Holes drilling division (Chuck lock): with steps of 10 degree.

Víťa - BF20 - upraveno na CNC + Mach3 + SS, soustruh CJM250, MK3 Průša, ostřička nástrojů
a má i své stránky - a má tam i nějaké schema co má jak zapojeno / vymyšleno

při řezání závitů snímá jak polohu vřetene tak i polohu posuvového šroubu a tak to synchronizuje
Synchronization is done with 2 proximity sensors (one for the leadscrew and one for the spindle). A simple Reset System with a NAND gate will let the leadscrew running sync.
