Cletus' PM-935TS-3PH Mill Log

[Cletus]

Almost there, most of the whistles and bells are on it. Have to go hunt down some Metric hardware next week and proceed to mount the glass scales.

Chip management system

Very convenient device!

David Best has great installation info here:

Morton Quill Speed-Stop on PM935 Mill

This is a tutorial about how to change out the factory supplied quill depth stop on a J-head milling machine, and replace it with an upgraded version that has quick positioning capability. This particular depth stop is made of stainless steel in the USA by Morton Machineworks and is available...

(.....just some M5 x 30 SHCS keeping back the installation of the scales, will go get some tomorrow)

 

[Cletus]

So, these are the very first parts made on the new mill. They are the standoffs for mounting the Z-axis DRO Scale rail. One is purposely made 0.020" shorter than the next for proper scale alignment.

The selected surface for mounting the Z scale:

 

[Cletus]

Well, the DRO is up and running.
The machine is now fully commissioned (one week of full-time work).

Cletus’ Revised On-Machine Setup 2021/09/10


B037 = 01 Show All parameters

A082 = 230 Motor Nameplate Voltage

B012 = 11 Motor Nameplate Amperes

F001 = 60.00 Output Frequency Setting

A003 = 60 Base Frequency

A004 = 120 Maximum Frequency

A061= 120 Frequency Upper Limit

A062= 0.00Frequency Lower Limit

H004 = 4 Motor Poles
F002 = 3.00 Acceleration Time

F003 = 1.00 Deceleration Time
A001 = 01 Frequency Source (ext Pot) Pot on terminals “H”, “O”, and “L”

A002 = 01 Run External
C001 = 00 Set Fwd to terminal “1”

C002 = 01 Set Rev to terminal “2”

C003 = 06 Set JOG to terminal “3”

A038 = 4 Jog Frequency, 4.0 Hz

B031 = 10 High Level Access

For braking resistor implementation add the following:
A042 = 5 Manual torque boost value (0-20%)
A054 = 60 %DC braking force for deceleration (0-100%)
A083 = 1 AVR filter time constant (0-10%)
B029 = .5 Deceleration rate of active freq. Matching (.1 to 3000.0)
B090 = 10 %Dynamic braking usage ratio (0-100%)
B092 = 01 Fan control

B095 = 02 Dynamic braking control (BRD) selection

B097 = 60 Should set automatically to resistor value
B131 = 390 Decel. overvolt. Suppress level
B133 = 1 Decel. overvolt. Suppress proportional gain

I fondly call it the "Nut-Cracker", cause if you leave it on, in all likelihood, the knee handle will crack your nuts when you use the motor drive!
Notwithstanding, just a simple device, cut crudely from HDPE flat-stock, that holds the knee crank engaged for hand adjusting Z-travel and quickly removed for motorized running (or, easily pulled out on your way to the floor, after your nuts have been indeed cracked!)

 

[HighWall]

I have a 935TV with most of the additions you've mentioned. I really enjoy working with (and on) this machine.

All I'm lacking is the Z-axis power feed and hooking up the mist collant system. That Z-axis feed is looking better and better to me.

 

[Cletus]

Oh yes, the Z-axis power drive is indespensible
