When your CNC lathe faces the dilemma of blade replacement every 2 hours during 45# steel roughing, severe chip adhesion during 304 stainless steel machining, or frequent chipping due to interrupted cutting of mold steel — the CCMT120408-PM 4235 CNC Turning Insert will provide you with a disruptive machining solution. This professional tool integrating gradient cemented carbide technology and multi-layer CVD coating is specially designed for steel, stainless steel and mold steel machining. With a 180% tool life improvement and 40% metal removal rate breakthrough, it redefines the standard for high-efficiency cutting.

Perfectly suitable for rough to semi-finishing of ordinary structural steels such as A3 steel and 45# steel. Recommended parameters: Ap=0.8-2.5mm, Fn=0.1-0.6mm/r, Vc=150m/min. In machine tool bed guideway machining, it achieves efficient cutting with a single feed of 2mm, and the machining efficiency is 40% higher than that of traditional inserts.

Aiming at the machining difficulties of 304 and 316 stainless steel, the special coating formula effectively inhibits work hardening. In medical device part machining, the cutting edge remains sharp after 8 hours of continuous cutting, avoiding dimensional deviation caused by frequent tool changes, and the qualification rate is increased from 82% to 99.7%.

Suitable for cavity machining of pre-hardened mold steels (HRC30-45°) such as P20 and 718H. Used with high-precision tool holders, it can achieve a surface roughness of Ra0.8μm, reducing the subsequent polishing process time by 50%. In large injection mold machining, the single-piece tool cost is reduced to 1/3 of the traditional scheme.

• Installation Points: Ensure the contact area between the insert and the tool pad is ≥90%, and the clamping torque is controlled at 25-30N·m to avoid insert deformation due to over-tightening
• Cooling Suggestions: When using emulsion cooling, the flow rate should not be less than 4L/min, and the nozzle should be aligned at a 30° angle to the cutting area
• Wear Judgment: When the flank wear reaches 0.3mm or the crater depth exceeds 0.15mm, the insert should be replaced in time
• Storage Conditions: Store in a dry and ventilated environment with temperature 5-30℃ and relative humidity ≤60%, avoiding contact with corrosive substances

Each CCMT120408-PM 4235 insert has passed the ISO 9001 quality system certification, and the cutting edge precision is controlled within ±0.01mm. We provide:

• Custom cutting edge grinding service for bulk purchases
• 7-day no-reason return and exchange (unused state)
• 24-hour machining scheme consultation by professional technical team
