Product Overview

This single segment cold press mould for core drill bits is specially designed for room-temperature pressing of single core drill segments, replacing traditional hot pressing with cold forming technology. Optimized for high-precision drilling of hard and brittle materials like ceramics and tiles, it achieves precise pressing of single segments at ambient temperature, avoiding thermal damage to diamond abrasives. Suitable for producing single segments of 30-150mm thin-walled drills, especially for small-batch customized orders and R&D sampling.

Product Features

Low-temperature Precision Pressing Process：Using a servo hydraulic system for 0-60 tons constant pressure pressing, segment density uniformity is controlled within ±1.2%, retaining original diamond sharpness, increasing cutting efficiency by 25% compared to hot pressing, while reducing energy consumption by 40%.

High-wear Resistance Composite Material：The cavity is made of DC53 die steel with vacuum quenching + cryogenic treatment, surface hardness reaching HRC64-66. Combined with TD coating technology, anti-adhesion wear resistance is increased by 3 times, capable of withstanding over 80,000 cold pressing cycles, extending mould life to 4 times that of traditional materials.

Single-hole Precision Forming Design：Adopting an independent single-hole cavity structure with laser positioning system, hole position accuracy is controlled within ±0.05mm, segment radial runout ≤0.03mm, meeting high concentricity requirements of thin-walled drills and reducing drilling yaw risks.

Quick-release Single-cavity Structure：The mould uses a modular single-hole design, single cavity replacement time ≤3 minutes. With a manual fine-tuning device, it supports 0.1mm-level hole diameter adjustment, adapting to fast switching of multiple segment specifications, ideal for small-batch multi-variety production.
