Other Repair Services
Many modern machines have a plastic type of way liner called TURCITE. It is a very durable material that wears very well. When the way lube is lacking or contamination enters the lube system the turcite tends to lose its effectiveness, becoming soft and gummy in nature, thus separating from the machine casting. Although many popular thicknesses are available, the correct way is to machine it to the desired thickness. This allows for a nice mating surface, to work in harmony with your machine slide ways. It is imperative the lube system is evaluated for its capabilities of delivering the proper amount of lube to the NEW TURCITE. Being Shop Based and Field Mobile, RAKO Inc can offer a COMPLETE TURN KEY Job , depending on your desires.
This type of machine may have ball screws for the travel movements of the table.
The measured accuracy of the turcite project may be reflective of the quality of the ball screws and nuts, as well as the thrust bearings. If the turcite and table area was lacking lube, it is a highly probable the ball screw was challenged as well.

Clutch / Brake Adjustment
Vertical Turret Lathes (Bullard Type) can be commonly referred to as VTL’s. Most brands are equipped with a mechanical or hydraulic actuated type of clutch / brake combination. This arrangement is used to inch the machine during set up or part inspection. Over time the clutch packs / discs wear and lose their crisp responsive action. The sluggish action of either the clutch or brake action(s) is a signal adjustments may be needed. This DUPLEX Pack is sensitive to adjustment. Over tightening can and will result in damage to the internal activation fingers. Some machines are equipped with electromagnetic clutches, which relies on voltage to control the starting and stopping action. Should you need help in determining your machine clutch / brake type, please send several pictures of the general machine image to make your clutch / brake type determination. If the machine is equipped with a pendant control, most likely it is equipped with Electromagnetic OR Hydraulic actuated clutch / brake packs.
Gear Box Repairs
Spindle Speeds and the Feed / Rapids Movement(s) of the machine are generally arranged by a gear box configuration. Speed selections are usually made by a mechanical movement of gears by reference of shifting forks. Shifting Failures occur when the shifting forks fail to move the gears to the correct position. This can be a result of broken sheared pins – worn keys – broken jaw clutch or yoke fingers – stripped gear teeth – failed bearing, or a combination there of. RAKO can provide phone assistance to help with a preliminary evaluation, to isolate the trouble spot. Should a more in-depth determination be desired, a Field Service Call may be in order.
Rail / Turret Head Repairs
Most Rail Heads are moved by an Acme Screw / Nut configuration. Over time the threads on the Screw / Nut become worn and may fail. This issue can be addressed
By replacing the Screw & Nut. Most likely, a custom made screw & nut will be needed.
Having Elevated Wear on your Rail / Turret Head, can cause your Cutting Tool Tip be below centerline, resulting in accuracy issues. Problematic Indexing of the Turret Head is usually caused by worn gears – pins – and bushing in the manual indexer for tool selection. Should one be experiencing these issues, a Phone Call to RAKO can quickly give you insight as to your choice of Repair Options.
