Installation Example 1 for the "Varimec SSV5" Servo Feed Drilling Unit (Hydraulic Unit Replacement)

Installation Example 3 Varimec SSV5 (1)

Varimec modelSSV5-2610
WorkpieceOil gauge level hold on a crankcase
Shape1-φ12 drill x28L + φ23 spot-facing x3L
ToolsForming tool shape, super-hard burnishing drill

Before Installation

 Processing with hydraulic slide plus spindle unit
Stroke: 250mm

Results of Installation

  1. A 300 mm long stroke makes the slide table unnecessary.
  2. Shortening the tool used extends tool life and reduces costs.
    A more rigid tool also improves the machined surfaces of the hole and the spot-faced area (end surface of the oil gauge).
  3. Possible to carry out a variety of processing tasks by selecting NC control programs.
  4. Setting a second origin results in shorter cycle times. Tool replacement is also easier.
  5. Simultaneously changing the feed rate of the scrape sink part and the number of spidle rotations gives optimal cutting conditions, reduces processing takt time, and improves quality (machined surfaces, accuracy).
  6. Incidental equipment such as hydraulic tanks, plumbing and electromagnetic valves are no longer needed, which reduces costs.
    Seasonal variations in production (such as reduced feed rate due to lower operating temperature of oil in winter) are eliminated, making production planning easier.
