Coolant Chiller - Installation

1

Small VF

Secure the drill template to the enclosure in the location specified by the diagram. Use 5/16 drill bit to make holes using template.

Note:  For VF-2YT that have a stiffener on back panel use a spacer and longer bolts to mount.

For all models except those stated below, place drill template on right side [4] of the stiffener otherwise for the models stated below place on left side [3].

  • VF-3YT/50
  • VF-5/50XT
  • VF-5/50TR
  • VF-5/50

2

Align the upper bracket [1] with the upper three holes drilled in the enclosure panel using the template.

Raise the left side window and install the coolant chiller upper bracket [1] onto the enclosure panel using the sealing washers [2] and machine screws [3]. Do not fully tighten the machine screws.  Make sure the position of the upper bracket can still be adjusted by hand. 

 Note: For VM-2, VF-2YT and VF-2SSYT equipped with SMTC-50 and built before 01/2020. These machines have a stiffener [4] on the back panel that require a spacers.  Install the spacers [5] (P/N 59-1822) in between the back panel and the upper bracket.  Install the longer screws (P/N 40-1978) and washers (P/N 45-0184).

Do not fully tighten the machine screws.  Make sure the position of the upper bracket can still be adjusted by hand. 

 

3

Use the hooks on the top of the coolant chiller to hang the coolant chiller from the upper bracket and put 2 machine screws in the bottom.

 

4

Install the hex nuts [1] onto the upper bracket.  

Align the coolant chiller with the lower two holes drilled in the enclosure panel using the template.Install sealing washers [2] and machine screws [3] onto the coolant chiller.

Tighten all the fasteners securing the upper bracket and coolant chiller.

 Note: For the VF-2YT that have a stiffener on the back panel install the spacers (P/N 59-1822) in between the back panel and the coolant chiller.  Use the longer screws (P/N 40-1978) and washers (P/N 45-0184).

Coolant Filter - Installation

1

Install as shown, 1/2 of the threads should be engaged.

Slide the coolant filter assembly [2] onto the machine screws [1] and tighten.

Install hose caps onto all the barb fittings.

2

Route the coolant hoses as shown.  Secure the coolant hoses to the barb fittings with hose clamps.

If a coolant hose does not reach its barb fitting create a jumper hose using a double sided barb fitting.  Allow each hose some slack so it does not kink.

Route the coolant hose [1] from coolant pump to the filter assembly.

Route the coolant hose [2] from the filter assembly to the heat exchanger.

Route the coolant hose [3] from the waycover washdown to the filter assembly though the cable carriers under the coolant chiller. Secure the waycover washdown hose with a cable clamp [5].

Route the temperature sensor cable [4] along the waycover washdown hose.  Secure it to the waycover washdown hose between the sensor and the cable clamp using a zip tie.

Route the coolant hose [6] from the washdown spray nozzle to the filter assembly.

Route the coolant hose [7] from the flood coolant to the heat exchanger.

ST Coolant Chiller - Installation

1

Secure the drill template to the enclosure in the location specified by the diagram. Make sure the template is flat on the enclosure. Use a 5/16 drill on the top 3 holes on the template. Use a 7/32 drill on the bottom 2 holes on the template. Deburr the holes after drilling.

ST-10/15 [1]

  • X = 2"

2

Remove the rear panel from the machine.

Install the bracket [1] with the upper three holes drilled in the enclosure panel with the button head screws[2].

Reinstall the rear panel to the machine.

3

Use the hooks on the top of the coolant chiller to hang the coolant chiller from the upper bracket.

4

Install the hex nuts [1] onto the upper bracket.  

Align the coolant chiller with the lower two holes drilled in the enclosure panel and install the self tapping screws[2].

5

Disconnect the coolant hose[1] from the coolant pump and connect it to the lower fitting on the coolant chiller.

Connect the hose[2] that was included with the coolant chiller kit to the upper fitting on the coolant chiller and the coolant pump.

Electrical - Installation

Electrical Safety

Caution: When maintenance or repair is performed on CNC machines and their components, you must always follow basic safety percautions. This decreases the risk of injury and mechanical damage.

Push [POWER OFF].

Set the main circuit breaker to the [OFF] position.

Lock the main circuit breaker. Use an approved lock with an approved safety tag.

Danger: Before beginning any work inside the control cabinet the High Voltage indicator light on the 320V Power Supply / Vector Drive must be off for at least 5 minutes. If the voltage indicator light is on, do not touch the electrical components. The high voltage in the electrical cabinet can kill you. Some service procedures can be dangerous or life threatening. DO NOT attempt a procedure that you do not fully understand. If you have any doubts about performing a procedure contact your Haas Factory Outlet (HFO) and schedule a service visit.
