Deep Hole Drilling Machines-TZK400

The TZK400/500 CNC scraping and rolling machine tool is a multi-purpose scraping and rolling machine tool designed based on the structural characteristics of the Italian Taki deep hole drilling and boring machine. It is suitable for scraping and rolling mixed processing of various hydraulic cylinders, cylinders and other precision pipe fittings. The processing hole diameter accuracy can attain IT7~IT9 level, the surface roughness can reach Ra0.2~0.4μm after rolling, and the processing straightness is less than 0.15mm/meter (the processing allowance of hot-rolled pipes is uniform and much less than 6mm.

The machine tool can choose three processing methods: a. The workpiece rotates, the device does not rotate, and the tool only makes reciprocating feed motion. It is appropriate for rough and fine boring and rolling processing of hot-rolled steel pipes; b. The workpiece rotates, the device rotates. , the working method in which the tool makes reciprocating feed motion, suitable for hard and fine boring and rolling processing of hot-rolled and large-gauge cold-drawn steel pipes; c. The workpiece does not rotate, the tool rotates, and the tool makes reciprocating feed motion. , suitable for fine boring and rolling processing of cold-drawn and slim steel pipes with small margins. The rotation of the workpiece has two main advantages: 1. When the workpiece rotates, the processing tool tends to the middle of the workpiece, which can greatly improve the straightness of the workpiece; 2. Hot-rolled pipe processing produces a giant amount of iron filings, and the rotation of the workpiece is conducive to the discharge of iron filings.
