• Compatibility

  The triangle carbide inserts have different chip breakers, making some inserts unsuitable for certain customers' lathes. Moreover, different lathes have different insert holders that match specific inserts. Therefore, buyers should ensure they buy inserts compatible with the customers' lathes and holders.

• Grade Selection

  Various manufacturers make triangle insert carbide tools from different carbide grades. Ideally, each grade is designed to cater to a specific customer's machining requirement. So, customers should select grade types based on the materials their customers plan to machine as well as the cutting conditions they will use.

What to Pay Attention to When Maintaining Triangle Cemented Carbide Inserts

To maximize the life of Triangle cemented carbide inserts, business owners should offer their customers insert maintenance guidelines. These maintenance procedures will help them maintain the performance of their Triangle inserts.

• Proper Storage

  They should store the inserts in a dry, dust-free environment. Extreme temperatures or high humidity will degrade the insert quality. Moreover, surrounding the inserts with foam or storing them in a dedicated toolbox prevent insert damage. In addition, avoid storing tipping tools with the inserts to prevent hacksaw tips for steel jobs from damaging the inserts.

• Regular Cleaning

  Machining debris can accumulate on the inserts over time. This debris will affect the performance of the insert if it builds up considerably. Business owners can advise their customers to regularly clean the inserts using a wire brush or compressed air to remove debris after every use. Further, they should use a suitable solvent to clean any stubborn residue on the inserts.

• Inspection for Wear

  Users should regularly inspect the triangle inserts for signs of wear. They can do this after every job or during big breaks. In the inspection, users need to look for chipping, cracking, or noticeable wear on the cutting edges. They can then use a magnifying glass to check for small fissures or micro-chipping. Users should then replace worn inserts promptly to avoid further damage to workpieces.

• Edge Maintenance

  Users can prolong the life of their inserts by carefully reconditioning the edges of new inserts using a diamond wheel or a specialized honing tool. However, only skilled staff should handle edge maintenance because improper honing can affect the quality of the cut.

• Monitoring Cutting Conditions

  Business owners should ensure their customers maintain optimal cutting speeds and feeds when using the triangle inserts. Excessive heat or force will cause unnecessary wear on the inserts. Therefore, avoiding such conditions will reduce the wear rate of the inserts. Also, they should use the recommended cutting fluids to reduce friction and dissipate heat.
