Machines, Service, and Support from Hartwig, Inc.

A regular preventive maintenance program can have a variety of benefits to your operation: preventing unplanned downtime, prolonging the life of your machines, and even helping your team learn to take better care of your equipment. We customize our preventive maintenance programs according to what type of equipment is running in the shop and what applications are being performed. 

While no two preventive maintenance programs are exactly the same, this list provides a basic overview of the activities that should be performed on a regular basis to keep your machines running at their peak.

Daily preventive maintenance

Your operators should perform these activities at least once per day, or even better, once per shift:

• Check hydraulic pressure and fluids, chuck pressure, lube levels; and, if you have a cooling system, check the cooling unit level.
• Clean out chips, grease parts as needed, clean off windows and doors, and wipe down and lubricate way covers for smooth movement.

Every three months or 500 hours

The following activities can be performed by either your team members or your Hartwig technician:

• Check hydraulic pressure and fluids, chuck pressure, lube levels; and, if you have a cooling system, check the cooling unit level.
• Clean out chips, grease parts as needed, clean off windows and doors, and wipe down and lubricate way covers for smooth movement.

Every six months or 1,000 hours

Your Hartwig service technician will perform the following activities twice per year:

• Clean the coolant tank of sludge, chips and oil.
• Clean the chuck and jaws.
• Drain the hydraulic tank and replace the hydraulic oil, and change the line filter and suction filter.
• Clean the radiator and make sure the radiator fins are straight.
• Drain and clean the lubrication unit and add fresh way lube.
• Drain and refill the cooling unit.
• Check the leveling of your machine and adjust if necessary.
• Clean and inspect way wipers and replace any wipers that are damaged.

Once per year or every 2,000 hours

Your Hartwig service technician will perform these activities once per year: 

• Check the headstock for taper.
• Check the spindle for radial and end play.
• Check the chuck cylinder for run out.
• Check the tailstock for taper.
• Check turret parallelism and inclination.
• Run a backlash program to check the backlash in X and Z axis.
