Production Process
|
Core Equipment
|
Equipment Purpose
|
|
Powder Pretreatment
|
Ball Mill
|
Used for grinding and mixing cemented carbide raw material powders such as tungsten carbide. It refines bulk or coarse-grained raw materials into micron-sized powders and homogenizes multi-component powders, ensuring the consistency of the subsequent green compact composition and sintering performance.
|
|
|
Spray Drying Tower
|
Performs rapid drying and granulation of mixed powders to remove moisture and excess solvents, forming granular powders with good fluidity and uniform particle size. This lays the foundation for accurate mold filling and uniform density of pressed green compacts.
|
|
Compaction Molding
|
Electric Direct-Drive CNC Press
|
Adapted for precision forming of cemented carbide inserts. It uses CNC full-closed-loop control technology and provides instantaneous large thrust through synchronous direct-drive motors to precisely control compaction pressure and displacement. It can realize near-net-shape forming of inserts with complex shapes such as chip breakers, ensuring the dimensional consistency of batch products.
|
|
|
Servo Molding Machine for Cemented Carbide Powders
|
Precisely regulates the movement of upper punches, master molds and other components through a servo system to achieve high-precision forming of fine powders. It supports the compaction of complex structures such as multi-step and special-shaped cutting edges, reducing subsequent processing after sintering. Meanwhile, it optimizes the density of different areas of the insert body through gradient compaction to improve mechanical properties.
|
|
Sintering Treatment
|
Ridder Gas Pressure Sintering (GPS) Furnace
|
Integrates multiple functions including vacuum dewaxing, vacuum sintering and pressure sintering. It can introduce gases such as argon to adjust the atmosphere, with a maximum temperature of 2200℃. It enables densification of cemented carbide inserts, reducing internal pores and improving hardness and wear resistance. Its rapid cooling technology can significantly shorten the cooling time of the high-temperature furnace body, reducing energy consumption during non-sintering stages.
|
|
|
Degreasing Furnace
|
Serves as an auxiliary equipment before sintering. It specifically removes forming agents such as PEG and paraffin contained in pressed green compacts, avoiding gas generation from the high-temperature decomposition of forming agents during sintering which may cause defects such as pores and cracks in inserts, thus ensuring the structural integrity of sintered inserts.
|
|
Pre-Coating Pretreatment
|
Automatic Sandblasting Equipment
|
Performs sandblasting on the surface of sintered inserts before coating to remove oxide layers, residual impurities and burrs. It also increases the surface roughness of inserts, greatly improving the bonding strength between the subsequent coating and the substrate and preventing coating peeling.
|
|
|
Automatic Cleaning Equipment
|
Adopts a combined water and solvent cleaning process to thoroughly remove dust and oil attached to the surface of inserts after sandblasting. It ensures the surface cleanliness of inserts, prevents impurities from affecting coating uniformity and adhesion, and provides qualified substrates for the coating process.
|
|
Coating Processing
|
Ridder Chemical Vapor Deposition (CVD) Coating Furnace
|
Relying on Ridder's core chemical vapor deposition technology, it causes chemical reactions of coating gases under high-temperature and high-pressure environments to deposit wear-resistant and high-temperature-resistant coatings (such as TiN, TiCN) on the surface of inserts. This significantly improves the wear resistance and high-temperature oxidation resistance of inserts during cutting.
|
|
|
Physical Vapor Deposition (PVD) Coating System (e.g., German Metaplas Automatic Coating System)
|
Deposits coating materials onto the surface of inserts through technologies such as arc and magnetron sputtering, forming a smooth coating with strong bonding force. It is suitable for precision cutting inserts requiring high coating surface finish, which can improve chip removal performance during cutting and extend the service life of inserts.
|
|
Processing & Inspection
|
Cutting Edge Grinding Machine
|
Uses 4-axis or 5-axis grinding equipment to precision grind the cutting edge of coated inserts. It ensures the dimensional accuracy of the cutting edge reaches the micron level, guaranteeing the machining precision and surface finish of inserts during cutting.
|
|
|
Cutting Test Equipment (e.g., German DMG CNC Lathe)
|
Conducts cutting performance verification of finished inserts. Through the supporting measurement and analysis system, it detects key indicators such as the cutting life and wear resistance of inserts, providing data support for the optimization of insert process parameters and quality control.
