Deep Hole Boring Machines-TZK400

The TZK400/500 CNC scraping and rolling machine tool is a multi-purpose scraping and rolling machine tool designed primarily based on the structural characteristics of the Italian Taki deep hole drilling and boring machine. It is suitable for scraping and rolling combined processing of various hydraulic cylinders, cylinders and other precision pipe fittings. The processing hole diameter accuracy can obtain 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 plenty less than 6mm.

The machine tool can pick out three processing methods: a. The workpiece rotates, the device does not rotate, and the tool solely makes reciprocating feed motion. It is appropriate for rough and fine boring and rolling processing of hot-rolled metal pipes; b. The workpiece rotates, the device rotates. , the working method in which the tool makes reciprocating feed motion, appropriate for hard and fine boring and rolling processing of hot-rolled and large-gauge cold-drawn steel pipes; c. The workpiece does now not rotate, the tool rotates, and the tool makes reciprocating feed motion. , suitable for satisfactory 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 center of the workpiece, which can greatly improve the straightness of the workpiece; 2. Hot-rolled pipe processing produces a massive amount of iron filings, and the rotation of the workpiece is conducive to the discharge of iron filings.

We will specially customize equipment of such specifications and models according to user needs.
