HAWK MECHANICAL ENGINEERING SERVICES INC.

CNC Machine Services


Hawk specializes in electrical, electronics, and mechanical repair, rebuild, retrofit and maintenance of CNC machine systems. This can include rewiring the entire system and installing pre-engineered PLC systems.

Hawk can also replace relay logic with PLC controllers to eliminate electrical failures. Each rebuild includes, as needed, inspection and repair of all conduit, control panel and legend plates. Hawk inspects your machine geometry using laser technology.
Hawk also specializes in turcite replacement on machine ways and hand scraping to restore proper alignment.

In addition to rebuilding the mechanical components, we run detailed inspections on the following systems:
electrical, mechanical, coolant, hydraulic, lubrication.

For CNC machines that are mechanically sound, but have defective or outdate control; retrofitting is an economical alternative to buying a new machine. A retrofit involves replacing the CNC control and all other components, including

wiring. A retrofit can save you a substantial amount of money, since it only costs about 30% of the price of a new machine. Retrofitting is done by Hawk with total client satisfaction so that no discrepancy or flaws are seen further. With today’s technology, there are many CNC controls from which to choose- from sophisticated controls that run other software, to controls that run a given machine’s operation. Hawk engineers and technician specialists will help you make the right choice. Because we know CNC machines, we can assure the right retrofit to achieve your specific goals. Don’t discard expensive CNC machines or parts. Hawk can restore worn or damaged CNC machines regardless of make, model, manufacturer or long lead time for onsite work. Equipment thought un-repairable or even scrapped can usually be returned to manufacturers’ specifications and tolerances. Our CNC field engineers and technicians have a combined 50 years of experience. Our CNC field staff are factory trained and provide routine and complex repairs, rebuilds, retrofit and maintenance, alignments, electrical, mechanical, electronic, hydraulic, pneumatic services. We repair many types of machines. Instead of the brand and model of the machine we focus on the control that they are equipped with. That is what defines a machine, not necessarily the make and model. 

We can repair the following control systems (including the associated motor drives, power supplies, displays, etc.:

Now, these are just a few of the systems we see regularly. We encounter many new and one-of-a-kind repairs all the time and we have no problem completing them. We can repair pretty much any CNC machine and their components. This is because we do not base our repair tactics on simply replacing the components and giving it another try. We actually investigate the root cause of the problem down to the discrete components (resistor, microchip, etc.) and resolve the problem. This involves a lot of schematic drawing and actually understanding the functioning of the device rather than just putting a band-aid on the problem.
